Building an Ethereum Mining Rig - Part 2

First update to the guide "Building a 6Gpu Mining Rig for Ethereum" - Let's talk about Claymore.
This update supplements and does not replace the Guide to Build a 6GPU Mining Rig for Ethereum published on our site.

The substantial differences are due to the installation of the latest version of the Windows 10 Operating System, the mining on the Ethermine pool (in our opinion simpler than Dwarfpool) and the use of the XFX RX 580 8gb GPUs.

The first variant is found in Part 4 of the guide: the environment variables are not to be entered as they will be integrated directly into the bat file to start mining.

The second variant is found in Part 7 of the guide and leads us to "mine" on a different pool using the Claymore software.
Download the latest version at the following link: https://github.com/Claymore-Dual/Claymore-Dual-Miner

Once downloaded, unzip everything on a folder on your desktop and open the start.bat file with notepad. Clear the contents and copy the following command:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where instead of "your wallet address" you will have to put your Ethererum wallet - obviously without the quotes - and instead of worker you will put an identification number in case you build more RIGs (such as RIG1, RIG2, etc ...). We opted for the eu1 pool even if some on the discussion forums believe that the us1 is more profitable.

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner


The Ethermine pool offers a very well crafted and descriptive interface. In the Payouts section, after only 5 minutes of mining, you can decide the minimum amount of Ether to be transferred to your wallet by simply entering the IP address of the RIG.

We have decided to mine directly on the Ethereum address of our Exodus wallet. It is not recommended to mine directly on Coinbase, as reported on the site itself. Sin.

Nothing should be left to chance when you decide to build a mining rig for Ethereum.
The third variant is the most difficult of all. Once you have reached Part 5 of the guide, you can decide whether to continue or follow this update / variant. If you are here it is probably because you have run into some problem that the guide does not allow you to solve.

With the latest version of Windows 10, you may run into a kernel conflict between the operating system and AMD's Radeon Software Crimson ReLive Edition Beta for Blockchain Compute drivers. This conflict will prevent you from using Atiflash after installing the drivers.

Important: Before making any changes to the BIOS, please backup each GPU.

Important: first of all flash the GPUs with the original bios if for any reason you are forced to reinstall the operating system.


Still on Atiflash.
The advice would therefore be to flash the GPUs and then install the AMD drivers. Let's say it would be because you may run into another problem this time related to the GPUs themselves. Since each video card is different from any other, the bios mod of the GPU could crash the operating system showing the classic blue screen and displaying an error related to the Atimkdag.sys file.

This could be due to the fact that some GPUs have significantly higher performance in the calculation phase than others. We could call it a factory overclock but not using them for gaming we cannot say it with absolute certainty.

Having assessed these two drawbacks, the only safe solution is to flash all the GPUs, disconnect them except for the first one, install the Blockchain drivers (plus Atimkdag patch) and launch the mining command verifying that the operating system does not go into crash in the next 5 minutes.

Turn off the rig again and connect the second GPU so on up to the sixth. In the event that one or more video cards should crash the system, disconnect them. After that, it uses DDU from the provisional mode and flashes these GPUs with their original bios. At this point, connect them again, reinstall the Blockcain drivers (plus Atimkdag patch) and start mining definitively.

All the operations related to the use of Atiflash, DDU and driver installation are reported in Part 5 and Part 6 of our guide.
A little bit of Overclocking.
You will certainly find significant differences in performance between the GPUs.

At this point all that remains is to "operate" with an overclocking software. We opt for OverdriveNtool. Our constantly updated guide is available at the following link: https://www.cryptoall.it/2019/10/12/complete-guide-to-overdriventool/

Link to the official YouTube channel for verification: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

GPUs with modified bios will not leave much room for modification. You will have to proceed with the most extreme overclocking on those that mount the original bios; obviously always in small steps by saving the profile for each GPU. Our guide explains in detail how to do it.

Hoping to have been of help, we give everyone an appointment for the second part of the update on how to build an Ethereum mining rig in which we will explain in detail the dual mining on the Ethermine pool.

See you soon.

ACIS-mining and its 3 best algorithms

ACIS-mining and its 3 best algorithms
Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms.
📌 With the advent of ASICs for mining, it became possible to mine Bitcoin in much larger quantities than using video cards. ASIC is an integrated circuit specialized to solve a specific problem, in our case, only for bitcoin mining. These schemes are many times more profitable than video cards, because with more power (hash calculation speed) they consume much less energy. This served as a good reason to create a cryptocurrency mining business.
📌 In bitcoin and other blockchain systems, the complexity of mining depends on how quickly the miners find the block. Compared with the GPU and CPU, specialized #ASIC miners solve #PoW puzzles better and are therefore able to quickly find new blocks.
📌 Since PoW is still the preferred mining consensus mechanism, we propose to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: #SHA256, #Scrypt, and #X11.
🔹 The SHA-256 algorithm has a number of advantages over other information protection technologies. Over the years of use in the cryptocurrency industry, he has shown his resistance to various hacking attempts.
🔹 Scrypt is a cryptocurrency mining algorithm that was previously interesting to many single miners in view of its resistance to the so-called “hardware attack”. The speed of creating blocks in a Scrypt-based blockchain is about 30 seconds. The hashrate, like Ethash, is measured in Megahash per second. Scrypt, first of all, became popular due to its use in Litecoin #cryptocurrency.
🔹 X11 is an encryption algorithm in which eleven are used instead of one function. This means that this technology can provide a high degree of security, because in order to harm the system, an attacker will have to crack all 11 functions, which is very unlikely, because the changes made will be visible after breaking the first function, and developers will have a lot of time to protect the system before the hacker reaches the eleventh function.
Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining.

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

https://preview.redd.it/vhvj6v093df51.jpg?width=1024&format=pjpg&auto=webp&s=00c0c223d9758edec8ed49a8cb9024f96d3ee343
Greetings from the UMI Team! Our Whitepaper describes in detail the key pros and cons of the two mechanisms which the great majority of other cryptocurrencies are based on:
Proof-of-Work (PoW) — mining technology. Used in Bitcoin, Ethereum, Litecoin, Monero, etc.
Proof-of-Stake (PoS) and its derivatives — forging technology. Used in Nxt, PeerCoin, NEO, PRIZM, etc.
As a result of a careful analysis of PoW and PoS, which are designed to fight against centralization, there came a conclusion that they both fail to perform their main mission and, in the long run, they lead to the network centralization and poor performance. For this reason, we took a different approach. We use Proof-of-Authority (PoA) algorithm coupled with master nodes, which can ensure the UMI network with decentralization and maximum speed.
The Whitepaper allows you to understand the obvious things. This article will give you a clear and detailed explanation of the technology implemented in the UMI network. Let's glance at the heart of the network right now.
Proof-of-Authority: How and Why It Emerged
It's been over a decade since the first transaction in the Bitcoin network. Over this time, the blockchain technology has undergone some qualitative changes. It's down to the fact that the cryptocurrency world seeing the emerging Proof-of-Work defects in the Bitcoin network year after year has actively searched for ways to eliminate them.
PoW decentralization and reliability has an underside of low capacity and scalability problem that prevents the network from rectifying this shortcoming. Moreover, with the growing popularity of Bitcoin, greed of miners who benefit from high fees resulting from the low network throughput has become a serious problem. Miners have also started to create pools making the network more and more centralized. The “human factor” that purposefully slowed down the network and undermined its security could never be eliminated. All this essentially limits the potential for using PoW-based cryptocurrencies on a bigger scale.
Since PoW upgrade ideas came to nothing, crypto community activists have suggested cardinally new solutions and started to develop other protocols. This is how the Proof-of-Stake technology emerged. However, it proved to be excellent in theory rather than in practice. Overall, PoS-based cryptocurrencies do demonstrate a higher capacity, but the difference is not as striking. Moreover, PoS could not fully solve the scalability issue.
In the hope that it could cope with the disaster plaguing all cryptocurrencies, the community came up with brand new algorithms based on alternative operating principles. One of them is the Proof-of-Authority technology. It was meant to be an effective alternative with a high capacity and a solution to the scalability problem. The idea of using PoA in cryptocurrencies was offered by Gavin Wood — a high-profile blockchain programmer and Ethereum co-founder.
Proof-of-Authority Major Features
PoA's major difference from PoW and PoS lies in the elimination of miner or forger races. Network users do not fight for the right to be the first to create a block and receive an award, as it happens with cryptocurrencies based on other technologies. In this case blockchain's operating principle is substantially different — Proof-of-Authority uses the “reputation system” and only allows trusted nodes to create blocks.
It solves the scalability problem allowing to considerably increase capacity and handle transactions almost instantly without wasting time on unnecessary calculations made by miners and forgers. Moreover, trusted nodes must meet the strict capacity requirements. This is one the main reasons why we have selected PoA since this is the only technology allowing to fully use super-fast nodes.
Due to these features, the Proof-of-Authority algorithm is seen as one of the most effective and promising options for bringing blockchain to various business sectors. For instance, its model perfectly fits the logistics and supply chain management sectors. As an outstanding example, PoA is effectively used by the Microsoft Azure cloud platform to offer various tools for bringing blockchain solutions to businesses.
How the UMI Network Gets Rid of the Defects and Incorporates the Benefits of Proof-of-Authority Method
Any system has both drawbacks and advantages — so does PoA. According to the original PoA model, each trusted node can create a block, while it is technically impossible for ordinary users to interfere with the system operation. This makes PoA-based cryptocurrencies a lot more centralized than those based on PoW or PoS. This has always been the main reason for criticizing the PoA technology.
We understood that only a completely decentralized product could translate our vision of a "hard-to-hit", secure and transparent monetary instrument into reality. Therefore, we started with upgrading its basic operating principle in order to create a product that will incorporate all the best features while eliminating the defects. What we’ve got is a decentralized PoA method. We will try to explain at the elementary level:
- We've divided the nodes in the UMI network into two types: master nodes and validator nodes.
- Only master nodes have the right to create blocks and confirm transactions. Among master node holders there's the UMI team and their trusted partners from across the world. Moreover, we deliberately keep some of our partners — those who hold master nodes — in secret in order to secure ourselves against potential negative influence, manipulation, and threats from third parties. This way we ensure maximum coherent and reliable system operation.
- However, since the core idea behind a decentralized cryptocurrency rules out any kind of trust, the blockchain is secured to prevent master nodes from harming the network in the event of sabotage or collusion. It might happen to Bitcoin or other PoW- or PoS-based cryptocurrencies if, for example, several large mining pools unite and perform a 51% attack. But it can’t happen to UMI. First, the worst that bad faith master node holders can do is to negligibly slow down the network. But the UMI network will automatically respond to it by banning such nodes. Thus, master nodes will prevent any partner from doing intentional harm to the network. Moreover, it will not be able to do this, even if most other partners support it. Nothing — not even quantum computers — will help hackers. Read our post "UMI Blockchain Six-Level Security" for more details.
- A validator node can be launched by any participant. Validator nodes maintain the network by verifying the correctness of blocks and excluding the possibility of fakes. In doing so they increase the overall network security and help master nodes carry out their functions. More importantly, those who hold validator nodes control those who hold master nodes and confirm that the latter don't violate anything and comply with the rules. You can find more details about validator nodes in the article we mentioned above.
- Finally, the network allows all interested users to launch light nodes (SPV), which enables viewing and sending transactions without having to download the blockchain and maintain the network. With light nodes, any network user can make sure if the system is operating properly and doesn't have to download the blockchain to do this.
- In addition, we are developing the ability to protect the network in case 100% of the master nodes (10,000 master nodes in total) are "disabled" for some reason. Even this is virtually impossible, we've thought ahead and in the worst-case scenario, the system will automatically move to PoS. By doing so, it will be able to continue processing transactions. We're going to tell you about this in our next publications.
Thus, the UMI network uses an upgraded version of this technology which possesses all its advantages with drawbacks eliminated. This model is truly decentralized and maximum secured.
Another major drawback of PoA-based cryptos is no possibility to grant incentives to users. PoA doesn't imply forging or mining which allow users to earn cryptocurrency while generating new coins. No reward for maintaining the network is the main reason why the crypto community is not interested in PoA. This is, of course, unfair. With this in mind, the UMI team has found the best solution — the unique staking smart-contract. It allows you to increase the number of your coins up to 40% per month even with no mining or forging meaning the human factor cannot have a negative impact on the decentralization and network performance.
New-Generation Proof-of-Authority
The UMI network uses an upgraded version of PoA technology which possesses all its advantages with drawbacks virtually eliminated. This makes UMI a decentralized, easily scalable, and yet the most secure, productive, profitable and fair cryptocurrency, working for the sake of all people.
The widespread use of UMI can change most aspects of society in different areas, including production, commerce, logistics, and all financial arrangements. We are just beginning this journey and thrilled to have you with us. Let's change the world together!
Best regards, UMI Team!

Cryptocurrency Mining Today

Cryptocurrency Mining Today
Mining is one of the key concepts in the crypto world. Everyone who comes into contact with this sphere somehow wonders about the mining of coins. How profitable is mining in 2020, and what are the current trends?
by StealthEX
Crypto mining is a process during which a computer solves mathematical problems, resulting in the release of new blocks of information. This gives its owners a certain amount of coins, which is deposited in the total pot and registered in the public “ledger”, so-called blockchain. Machines in the network are also checking transactions with existing coins, adding this information to the blockchain as well.
As for the issue itself, the most well-known algorithm of mining is Proof-of-Work (PoW), used in the networks of Bitcoin, Litecoin, Ethereum and many others.
During the mining process, the latest transactions are verified and compiled into blocks. It is usually a series of calculations with an iteration of parameters to find a hash with the specified properties. The node which first solves this problem receives a reward. This approach was specifically designed to encourage those who provide the computing power of their mining machines to maintain the network and mine new coins.
It is usually no need for a newcomer to know and understand all the complicated details of the mining process, just how much they can earn with certain equipment and electricity costs.
Everything is designed in such a way that the complexity of calculations is steadily increasing, which then requires a constant increase in the computing power of the network. In 2009-2010, for mining bitcoin, miners only had to download and run the software on their personal computers, but very soon the network became so complicated that even with best PCs with a powerful processor, mining became unprofitable. That’s why miners started to use more effective video cards (graphics processing units or GPUs) and join them in so-called “farms”.
In most systems, the number of coins is determined in advance. Also, many networks are gradually reducing rewards for miners. Such emission restrictions were built into the algorithm to prevent inflation.
Thus, the cost of mining for smaller participants no longer pays off, which makes them turn off their hardware or switch to another coin where they can still make their profit.
In particular, on the evening of May 11, 2020, a halving took place in the bitcoin network, the reward for mining was halved, from 12.5 to 6.25 BTC. In June, the revenue of bitcoin miners decreased by 23%, to the lowest since March 2019.
However, in mid-June, the difficulty of bitcoin mining showed a record growth over the past 2.5 years. Mining the first cryptocurrency has become 15% more difficult. Although, by the beginning of July, the complexity had stabilized. The growing difficulty of mining the first cryptocurrency indicates that new miners have joined its network. Previously, some of them turned off the equipment, as it became less profitable to mine the coin due to a decrease in its cost and halving.
Now the absolute majority of new coins are generated by industrial mining. This is done by large data centers equipped with specialized computers based on the ASIC architecture. ASICs are integrated circuits that were initially optimized for a specific task, namely the mining of cryptocurrencies. They are much more productive than CPUs and video cards, and at the same time consume much less electricity. ASIC computers are the main type of equipment for the industrial production of crypto.
So now, after the halving, BTC coin mining has become even less profitable. For beginners, mining the first cryptocurrency is unlikely to be suitable. It is more often earned by large companies that have all the necessary equipment, access to cheap rental conditions, electricity and maintenance.
Hence newbies are better off starting with mining altcoins. It is even more profitable to work in a pool, that is, together with other miners. This can help to place farms in one place and negotiate a favourable price for electricity, so you can get a small but stable income dux to the total capacity of the pool.
Therefore, it has become much more difficult for regular users who have only non-specialized equipment at their disposal to generate virtual money. However, GPU developers have significantly increased the performance of their devices in recent years, so mining on a video card is still common.
Another important event that changes the situation in the mining sphere will be the hardfork of the Ethereum network with the turn to the Proof-of-Stake algorithm. For now, Ethereum is the most popular altcoin for GPU mining, but Ethereum 2.0 will not require using such powerful equipment, so then it switches to PoS, GPU owners will have to look for alternative coins to mine.
At the moment the most popular altcoins for mining on GPUs are Ethereum (ETH), Ethereum Classic (ETC), Grin (GRIN), Zcoin (XZC), Dogecoin and Ravencoin (RVN). There are actually a lot of mining programs that automatically determine which coin is more profitable to mine at the moment.
In the coming years, the market is waiting for a race of technologies. Manufacturers are investing in finding ways to increase hashing speed and reduce power consumption. Mining pools will play an increasing role. The market will also be affected by applications for mining cryptocurrencies on smartphones that require low computing power, such as Dash or Litecoin.

$1 of Bitcoin value created is responsible for $0.49 in health and climate damages in the US and $0.37 in China.

The rising electricity requirements to produce a single coin will lead to inevitable social crisis
Energy Research & Social Science Volume 59, January 2020, 101281
Abstract
Cryptocurrency mining uses significant amounts of energy as part of the proof-of-work time-stamping scheme to add new blocks to the chain. Expanding upon previously calculated energy use patterns for mining four prominent cryptocurrencies (Bitcoin, Ethereum, Litecoin, and Monero), we estimate the per coin economic damages of air pollution emissions and associated human mortality and climate impacts of mining these cryptocurrencies in the US and China. Results indicate that in 2018, each $1 of Bitcoin value created was responsible for $0.49 in health and climate damages in the US and $0.37 in China. The similar value in China relative to the US occurs despite the extremely large disparity between the value of a statistical life estimate for the US relative to that of China. Further, with each cryptocurrency, the rising electricity requirements to produce a single coin can lead to an almost inevitable cliff of negative net social benefits, absent perpetual price increases. For example, in December 2018, our results illustrate a case (for Bitcoin) where the health and climate change “cryptodamages” roughly match each $1 of coin value created. We close with discussion of policy implications.

Mining: Weird Time to Start, a Good Time to Think

Mining: Weird Time to Start, a Good Time to Think
Well, it’s supposed to be an optimistic article about most promising mining cryptos, but then something happened. No one was too naive to believe that the events unfolded around the COVID-19 pandemic will not affect global markets, but the turbulence that occurred was very significant and, what is most sad, it is still very difficult to say how soon the situation will stabilize.
https://preview.redd.it/9xxheofluzp41.png?width=1024&format=png&auto=webp&s=cd8ca033faddf57ea041e82ceadee1037b8587f1
Many people were already bothered that crypto mining is becoming less profitable in 2020 and will be meaningless very soon, but even though big companies having bigger resources took over most of the industry, cryptocurrency mining using video cards remains available to common users and still has potential.
Despite, the volatility of the cryptocurrency market hashrate of the Bitcoin blockchain network yet remains almost at the same level and that is a quite positive sign. At the moment, the most reliable option seems to be to leave mining to large ASIC-farms and return when the stock panic subsides and the prospects will be clearer.
Although Bitcoin is still the most popular cryptocurrency on the market, every year the complexity of operations necessary for its production increases, and rewards fall (after halving in May 2020, we will talk about 6.25 BTC per block). For mining many altcoins, the threshold for entry is much lower, therefore it makes sense to look for a more profitable option among them.
But first, let’s try to understand a little what conditions we need for profitable mining.
There are several crucial aspects that determine how profitable mining will be. These are such obvious things as the price of the currency or the amount of reward for the generated block.
And this is the reason it is now very difficult to calculate the possible income. One way or another, the market price of altcoins depends on the position of bitcoin, which is experiencing bad times. For several months, the world of crypto mining has been preparing for the May halving, because the reduced supply led to a significant increase in prices. This time should not have been an exception, but now when bitcoin does not rise above $5500 and risks falling below $3500, we can only make vague guesses about its potential price in May. Many analysts tend to believe that closer to the middle of April, the negative effect of the crisis should be reduced, and positive expectations from halving and a large amount of cash from investors should have a positive impact on the price of bitcoin. Altcoins, as a rule, repeat the dynamics of the first cryptocurrency and will also continue their growth to historical highs in the year’s future.
Next, you should also pay attention to the complexity of mining because it affects the time and energy spent on generating the block. Do not forget about the cost of electricity in your region, as one extra-large bill can negate all your efforts to earn money on currency mining.
Do not forget about expenses on a mining rig and it’s amortisation.
In addition to the above, you should find out how practical the chosen currency is: whether it can be exchanged for fiat or more popular coins, what fees are charged by exchanges that work with it, and what reputation it has in general.
In order to avoid unpleasant mistakes, it is easier and more reliable to check the possible profit in one of the many calculators.

Best altcoins to mine in 2020

Monero is the currency with the highest anonymity rates, which stays attractive to many users and remains one of the strongest altcoins. The specific proof-of-work hashing algorithm does not allow ASIC-miners, so it is relatively easy to mine using personal computer’s processors and graphics cards. AMD graphic cards are preferable for this task, but NVidia suits as well. The current block reward is 2.47 XMR.
Litecoin is one of the oldest Bitcoin forks, but unlike it uses a different “Script” PoW algorithm which allows less powerful GPUs to mine coins. Litecoin is on the most popular, and successful Bitcoin forks and considered one of the most stable cryptocurrencies. Block mining reward is 12.5 LTC.
Ravencoin is another Bitcoin hardfork, and like Monero’s its X16R algorithm is practically unavailable for ASIC machines. Raven keeps gaining popularity for many reasons – it has faster block time, higher mining reward (5,000 RVN at the moment) and secure messaging system.
Dogecoin is not a joke anymore. Hard to believe, but this currency once made for fun, became one of the most valuable ones. Like Litecoin it uses Scrypt algorithm and great for mining with GPUs.
One more Bitcoin fork Bitcoin Gold was made specifically to kick out ASICs and clear the road for GPUs. It may not be the fastest-growing currency, but it is definitely one of the most stable.
That’s all for today. Stay safe, cause health is our most important asset.

Pure PoW is DEAD

When I was 16, camping out in an airport waiting to board my first International flight to England I began chatting with a U.S. Airforce pilot who had camped up beside my group. Asking him what it was like to fly at mach speeds he replied in a very sober expression, “you have to be alert at all times. You see a mountain or some obstacle appear on the horizon, you better adjust now or you’re going to slam into it.” Maybe he was adding dramatic effect, I’ve never flown at mach speeds at low altitudes, but I never forgot it and the analogy it carries...especially so fitting for technology and progress.
This past week in cryptocurrency shined an important (and hopefully sobering) light on a “mountain” that appeared on our industries horizon...and has actually been visible to us for far too long already: Pure Proof of Work’s inevitable fate.
By pure, I mean consensus algorithms that use nothing but the original Bitcoin proof of work consensus model without updates or algorithm changes to address its weaknesses relative to the ever expanding technology used to hash it. This means Bitcoin, today’s Ethereum, Zcash, Ethereum Classic, and other coins that comprise most of the value in the top 100 cryptocurrencies. The original, unmodified form of basic PoW that most of these coins use is dead. This demise may not be fully appreciated today, but as sure as a mach-speed plane, unable to turn in time is doomed to collide with a mountain in its path, these blockchains must soon either accept their lack of security in today’s world or fork and upgrade to more effective solutions, some of which have been pioneered by smaller projects that don’t command as much hash power and therefore already had to face and address their need for extra security.
I believe it’s actually irresponsible to deny it and assume economics, hash power, market, sentiment or even self-preservation of network participants will be protection enough.
Because Bitcoin is the biggest (by market cap) of the pure PoW cryptocurrencies in existence today, I’ll establish my arguments using BTC, but the same goes for all pure PoW cryptos.
1 - Economics Bitcoin is often defended because it has the largest market cap of all cryptocurrencies and commands most of the capable hash worldwide that might be used to attack it. It is a “store of value” with proponents of this argument relying on few factors, limited supply combined with sentiment being one of the most prominent. They believe that this limited supply will inevitably drive the price up and, somehow, bitcoin will remain unequivocally secured and established.
Bitcoin has serious limitations in its adherence to the pure PoW model, and though the realities of competition has kept it free from major 51% attacks, I predict that it’s only a matter of time before it cannot command the majority of hash power that may be used to attack it. Lack of acceptance that consensus must use more than just PoW, even when checkpoints are an already accepted as necessary augmentation, leaves Bitcoin open to a catastrophic failure at some point in the future, which would affect the short term value of every cryptocurrency, even those that have addressed and solved the most glaring security challenges of a pure PoW model. Some projects have developed and are now using more advanced, more secure technology than pure PoW, and still remain fully decentralized. This is now an area where altcoins are leading, as they fill the security vacuum. With altcoins also having smart contracts and advanced currency capabilities and being potential stores of value as well, the landscape visible on the horizon in front of us looks quite different from the smooth sailing we have seen behind us with respect to projects relying on PoW and PoW alone. I’m not suggesting that Bitcoin should try to be everything that every other altcoin is becoming, but to rely on its single function as an argument of it’s security and sustainability while refraining from important technical advancements to secure its future, is foolish. The calculator is an important, valuable, and useful tool, yet people understood that it should be part of a more multifunction solution and now carry one around inside their smartphone.
The argument supporting Bitcoin’s status quo as a pure PoW blockchain and claiming it is perfect as is for whatever particular reason, is often combined with the following and includes an argument resting on self-preservation. In other words, why would anyone be nefarious and ruin their own wealth and store of value given the enormous hash power and cost it would take to attack Bitcoin? Bitcoin, then, relies on theoretical protection with idealistic boundaries.
2 - Hash Power and Hardware Capabilities This is sort of a 2 in 1 argument. Bitcoin is considered by many, the most secure blockchain in terms of pure hash power. In other words, more hash power is directed at Bitcoin than any other cryptocurrency and, there are limits to sha256d hashing speeds, economically and in hardware capabilities therefore it would be too expensive to attack Bitcoin and by the same token, make no sense to the attacker to do any wrong in this case (self preservation).
To assume technology, A: is limited to what we know now and B: will remain within these bounds for long, is just ignorant. What happens when sha256d can be hashed faster, when hardware innovations change the cost and capabilities involved? How do we know it isn’t possible now? What’s more, will Bitcoin always hold its position as the “special” coin due to its leading network hashpower that simply will never experience a world where there is enough available hash power from other sources to use for a 51% attack? The argument that Bitcoin will remain special is not an argument that its technology can protect it, especially with its roots as a project that grew from a figurative David with its sights set on the Goliath of the banking industry.
Look at the enormous hash power presently directed at Bitcoin and ask, what happens if that hash power is suddenly directed at another, less special coin, as part of a 51% attack? Is that other coin ready to defend in some way against that event? And how does this then impact Bitcoin? I would submit that at the end of the analysis, if the only thing protecting Bitcoin and its current technology from being doublespent to death is the fact that it is uniquely “special” because it is biggest, then as it unarguably becomes centralized among the largest Bitcoin participants and/or institutions, in an ironic way, refusal to improve technology could create exactly the systemic centralization that Satoshi was trying to prevent.
Even so, the idea that Bitcoin can always and forever remain the largest cryptocurrency and “special” as such, ignores historical realities that teach us differently. Remember “alta-vista”, the pre-Google winner of the search engine wars? Remember AOL? MySpace? The economics of bitcoin as people understand them today, the economics involved in mining pure PoW, the sentiment and value assigned to bitcoin and any coin now, can change as rapidly as Bitcoin emerged, even unexpectedly to the masses.
The ETC attack of only a few days ago just put the entire Cryptocurrency industry on notice. Any project without an active solution in place of immunity or at least a defense against a 51% hash attack is in trouble. I would argue that even though it will likely still take some time for market dynamics to enable an attacker to reasonably mount a 51% attack on the largest pure PoW cryptocurrency, Bitcoin, without new defense against such an attack, it is a question of when, not if.
The other day I identified a small handful of projects that have developed and are using defenses against 51% hash attacks, only one of which has a provable solution of hash attack immunity in place.
It’s important to note, any solution that can be seen as real progress over the Bitcoin protocol must be one that is decentralized. While some cryptocurrencies solve the 51% hash attack problem with a fully centralized approach, that truly misses the point of the original Bitcoin paper. Centralized databases are a different technology altogether, and implementing a centralized solution to a decentralized technology changes it entirely, in which case it’s more akin to just trying to brand your centralized database with the latest catch phrases to gain attention, support or funding.
Here’s a short list I identified of projects who have developed a defense or a complete solution to 51% hash attacks. To my knowledge, all of these solutions are now active on the respective project main networks, with the exception of Litecoin Cash, which is running on testnet at this time.:
As an industry, we need to face the fact that pure PoW is an incomplete solution to decentralized blockchain security in this age of cheap, fungible compute power. Pure PoW-only systems must evolve, and it’s time we look beyond to understand what are the best solutions that have evolved to address that fact. If you are part of a crypto project, no matter how large, you ignore the notice provided by the ETC attack at your own peril and the peril of your network participants.
My request is this… if you know of a project with a 51% hash attack solution, please provide some information below. If you totally disagree with the main point of this post, please provide a reasoned argument to prove me wrong or explain why pure PoW systems will remain viable indefinitely. As an industry, it’s time we see the blunt reality and apply innovation. Those who don’t will be reduced to interesting historical experiments.

Litecoin Difficulty Calculators are misleading. The proper approach to difficulty increases and new hardware ROI calculations.

Going through thread after thread I am consistently seeing a common misconception. The proper way to look at mining rig ROI rates is brought up in various places, but it is clearly being ignored en mass (i.e. the nooblets out there swarming in on our society).
Calculators like these below are simple calculations based on the current difficulty. http://www.litecoinminingcalculator.com/ http://www.coinwarz.com/calculators/litecoin-mining-calculator https://www.litecoinpool.org/calc
These provide a number of outputs revenue rates over different time scales.. Hr, Day, Month..year.. Which makes them very very misleading.
Let's walk through a couple scenarios and asses the current situation of the network, what difficulty rate increases are 'possible' and how hardware availability has an effect.
Example Scenario
If I were to pick up a Radeon 280x and get it hasing at ~700Kh (let's assume free electricity for the examples). One of these calculators would output the following:
0.36 LTC / Day 10.75 LTC / Month 130.88 LTC / Year
Often times you see someone buying some new mining equip saying - oh s*&^ I can drop $300 on a new card and earn 10.75 LTC in a month. Leading to the assumption the hardware will pay itself off in just 1 month's time.
However - reality quickly hits once you look at the network difficulty increases. The Litecoin network normalizes the difficulty every 2016 blocks such that the next 2016 blocks will have an estimated solution time of 3.5 days. Thus the difficulty will increase or decrease based on the network hashrate roughly ever 3.4-3.6 days (you should all know this - if you don't - read up https://litecoin.info/Main_Page).
Past difficulty increases have been between -14.82% and 20% with the last two increases being >13% - the largest 7 day increase in difficulty ever (source: http://bitcoinwisdom.com/litecoin/difficulty - bottom of the page). With the recent increase in LTC/USD and LTC/BTC prices - GPUs have been flying off the shelves and it is a generally accepted assumption that we will see a large network hashrate increase in the near future.
If we see similar ~10% difficulty increases every 3.5 days - we will be at a difficulty of 4600 in 1 month and 312000 in 2 months. The propagation of a 700Kh miner output is shown in the table here from my own calculator.
STABLE DIFFICULTY INCREASE SPEED 700 KH/s LTC/USD 40 $ DIFFICULTY JUMP/2016 Blocks 10% Time between Diff Jumps 3.5

If the difficulty jumps are a consistent 15% the story is grim and the output is as follows - the card should ROI sometime at the end of January. Unless you factor in electricity at ~$1 USD/day...

However..if we see a few 20% increases in the near term and then smaller increases therafter this story is not so ideal. Factor in electricity and you're likely to never make ROI.

The above examples assume a steady difficulty increase from now until forever - which as the past would suggest - is unlikely (LTC diff historically jumps all over the place with many near zero changes and some large positive/negative changes. The average diff change in the past 6 months is ~+2.3%).
There are only so many GPUs being manufactured, only so many miners mining LTC over another crypto at any one time and there is of course downtime for hardware issues. To assume there will be a 15% increase from now until the end of February every 3.5 days resulting in a difficulty 32X what it is now which may not sound unreasonable (65,000) - but in my opinion unlikely. Lets take a look at some numbers..
If The network hashrate reflecst the influx of new GPUs - it is therefore related to the number of GPUs produced and sold / unit time.
If there have been 100,000 GPUs sold and put online in the next month with an average hash rate of 500Kh/s running 24/7 the hashrate would roughly double. (increase by 50,000 GH/s)
1 million GPUs added to the network would increase the hashrate by roughly 500MH/s or 10x what it currently is now - bringing the difficulty to approximately 20,000. This still does not reach the 15% increase rate of 65,000 by the end of February - so you must ask yourself.. is a skyrocketing difficulty based on added recent interest reasonable?
From the 3rd example where the network hashrate increases in the short term and levels off in the long term - We only need to see an influx of 4-5X the current network hashrate before the end of December to increase the difficulty enough such that in the long term ROI may not be possible. This is the equivalent of ~400k GPUs.
So I employ you to ask yourself a few of the following questions
Just a bit of food for thought. Realistically calculate your ROI and proceed under the impression there are many new miners hopping on this bandwagon in the near term. Take comments that say "Diff is going to go through the rooooooof" skeptically and ask yourself what lies within 'reason'.
This all of course assumes a stable price at or near $40/LTC which is subject to great fluctuations. However, IMO the real way to judge a miner's ROI is by the # of coins it produces vs. the intiail cost of the hardware in coins at purchase. I.e.
Cheers.
EDIT 1: Two good calculator alternatives.
EDIT 2: Let's take a look at mining pools shall we?
At the time of posting per: https://www.litecoinpool.org/pools - the top 3 pools contain roughly 60% of the network hashrate. If you visit their pages we can deduce a bit of information about how many people are mining and rough orders hashrate magnitude.
http://wemineltc.com/stats https://coinotron.com/coinotron/AccountServlet?action=statistics
At wemineltc there are ~26000 workers outputting a total HR of 14.7 GH. At Coinotron the number of miners is not disclosed, however the top 20 miners account for 16% of the total pool HR. At LiteGardian there are 5118 miners outting a total HR of 9.2 GH.
So making a few assumptions - there are roughly 50-60k workers on the top 3 pools with ~60% of the network hashrate and 5-6% of that hashrate comes from only 20 miners. To continue, If there are 50,000 workers (rounding down) outputting ~50GH (rounding way up) - this is an average HR of 1MH/worker. (Still talking about the top 60% of the HR in the top 3 pools). But we know that ~2GH comes from 20 miners - and there are many people mining with rigs <2 top end GPUs - mining is certainly a 'top heavy' economy.
Now you must ask - how many workers does each miner run.. etc. I estimate that this approximate 50k workers equates to less than 25k individual miners. So ~25k miners have constitute the top 60% of the network hashrate and have an average of ~2Mh each.
How many people are LTC mining on dedicated rigs? Part time on gaming rigs? To me, looking at a number of ~1,000,000 people mining LTC at this time is far fetched and lies somewhere in the lower order of magnitude.. maybe 50-100k people on the entire network.
Back to my previous examples.. how many GPUs must sell and come online to increase the hashrate.. and how many new miners?
If every miner gets 1 new GPU hashing at 500KH and the number of miners triples and new miners have an average of 4 500KH GPUs... 25k * 500KH + 25k * 2000KH + 60GH (current rate) = 172GH network rate. (This would be ~300,000 new 500KH GPUs on the network)
I can see the network hashrate increasing 2-5 times in the near future (2-4 months), but without the advent of a new technology that increases hashrates significantly I believe the limiting factor will be two fold. New miners and quantity of available new GPUs.
Edit 3.

Idle-Empire - Earn PayPal, Gift Cards & More | An extensive overview

Introduction

This is a full overview about Idle-Empire, a GPT (Get-Paid-To) site that's been around since 2015. Idle-Empire is primarily targeted towards gamers, but they also have payouts through PayPal, Gift Cards, Cryptocurrencies, and Perfect Money - so I think it's a good fit for beermoney too!
Idle-Empire has a lot of different earning and payout methods, some that you won't find on regular GPT sites. I'll go over every earning and payout method in this post.

Links

You get 500 Points ($0.05) for free when you sign up through my referral link, and of course, you support me too. I'll also include a clean link for people who prefer not to use my referral link:

Referral Link | Clean Link

Supported Countries

As far as I'm aware, there are no country restrictions on Idle-Empire. Everyone can sign up. There are some earning methods where your country does not matter, for others it does matter. People from all countries are able to idle, mine, complete promotions, and collect referrals. The availability of surveys, offers, and videos depend on your country.

Currency Value

Idle-Empire uses the term "Points" for their virtual currency. 10,000 Points are worth $1.00.

Payout Proof

I can provide this Coinbase payout proof.

Payout Conditions

The minimum payout amount is $0.10 for most payout methods. Some payout methods like gift cards ($1.00 - $10.00) or PayPal ($2.50) have a higher minimum payout amount.
You'll need to verify your account before you can make your first payout. You can verify your account with your mobile phone number, a verification code will be sent to your phone number.

Earning Methods

In this section, I'll describe all available earning methods and add my personal opinion and experience about every method.

Surveys & Offers

I guess everybody here is familiar with the concept of surveys and offers. They are tasks that involve answering questions, downloading programs and mobile apps, registering on platforms, and much more. It's a grind but it can pay off since there are some offers that pay good money. Idle-Empire has a number of different offerwalls, here's a full list:
Personally, I like doing surveys and offers because they pay well. But it's also more work than other earning methods. No pain, no gain.

Videos

Idle-Empire has videos from EngageMe.TV, Smores.TV, and Hideout.TV. I believe many of you guys are familiar with those 3 providers, they are all owned by AdscendMedia. All you have to do is watch videos and sometimes there's gonna be an advertisement in between videos, and after every 3 ads, you get paid 50 Points.
I liked to do videos in the past because it was easy and fast. Now I do it less, I feel that it became slower because I get fewer ads than before.

Game Servers

You have to join the Team Fortress 2 game servers of Idle-Empire and every minute you receive 1 Point. That's 1440 Points per day, which is $0.144 per day or $4.32 per month. It's not much but you don't have to do anything for it except being on the server. This process is called "idling" because you don't do anything. Idle-Empire shows video ads on the servers, so I guess that's how they can afford to pay people for being on the servers.
Team Fortress 2 is free-to-play on Steam, so everyone can just install it.
Idle-Empire also has an Autojoin tool which makes sure you automatically get reconnect to the server in case of a disconnected (can happen if your internet is down for a moment).
I'm usually on the game servers 24/7 because it's free money for me - my computer is always running anyways and having the game run in the background doesn't bother me since it's not slowing down my computer.

Mining

Most people will have noticed the cryptocurrency craze during 2017 and 2018, where mining also played an important role. Idle-Empire has its own cryptocurrency miner and you get paid for running it on your computer.
The average hashrate is currently 261 hashes per second. There's a calculator on the Idle-Empire website and it says that you earn 32,451 Points per month with that hashrate - that's $3.24. Note that this is just the current average, you might earn less or more depending on the GPU and CPU you have.
The issue with mining is that it takes your computer a lot of its CPU/GPU power, so you won't be able to use it for other stuff in the meantime. Your computer will also consume more electricity. I believe mining isn't worth it for most people anymore unless you don't pay for electricity.
I've used mining about 10 months ago or so and it was much more profitable at the time, I was making $0.80 - $0.90 per day. Haven't done it since the profitability went down, I think for most people it's only worth it now if you have free electricity.

Referrals

Idle-Empire has a simple referral system - you earn 20% of what your referrals earn through surveys/offers, servers, and mining. Here are the terms:
20% is pretty nice and I believe it can be a good passive income if you get active referrals.

Promotions

Promotions are basically offers from Idle-Empire. Most promotions are simple to complete.
There are some promotions that you can do on a daily basis just by pressing a button, that's pretty good. Also, I think it's worth to complete all the tasks that just require a few button clicks like verifying your email or following them on social media.
Here's a full list of all promotions:

Basic

Follow Social Media

Daily Tasks

Invite Friends

Create Content

Payout Methods

In this section, I'll quickly summarize the available payout methods.

PayPal

I'm sure everyone is familiar with PayPal. Idle-Empire sends USD to your PayPal account. There's a fee of $0.30 + 2.9%.

Gift Cards

They currently offer gift cards for the following platforms:

Cryptocurrencies

Idle-Empire has cryptocurrency payouts through Coinbase. The coins will be sent to your Coinbase account with zero fees. These currencies are supported:

Perfect Money

Perfect Money might be an alternative to PayPal for some people, especially when PayPal isn't available in your country. Perfect Money funds can be converted to Bitcoin, Skrill, Neteller, Payeer, Payoneer, and many others. Idle-Empire sends USD to your Perfect Money account.

BitSkins

BitSkins is a marketplace for Steam items, mainly for CS:GO and TF2 skins but many other games are supported too. Idle-Empire sends USD balance to your BitSkins account.

OPSkins

OPSkins is a marketplace for virtual and physical items. Idle-Empire sends Operation Points to your OPSkins account.

CSGOShop

CSGOShop is a marketplace similar to BitSkins but apparently, it has fewer users and supports fewer games. Idle-Empire sends USD balance to your CSGOShop account.

KeyJoker

KeyJoker seems to be a website where you can buy cheap indie Steam games. Idle-Empire sends credits to your KeyJoker account.

Boosters

Idle-Empire has "Boosters" that are randomly created on weekends (Saturday and Sunday). Boosters temporarily increase the earnings for one earning method, the boost can range from 1% to 100% and lasts a few hours. I've seen boosters for surveys/offers, videos, mining, and the game servers.

Conclusion

Idle-Empire can be a good alternative to traditional GPT sites for many users, especially since it doesn't have any country restrictions.
It has some unconventional earning methods like idling, mining, and some promotions but you'll also find the usual surveys, offers, and videos. Idle-Empire has many different offer walls, so that's nice if you like to grind.
The payout methods are primarily targeted towards gamers but they also have payouts through PayPal, Gift Cards, Cryptocurrencies, and Perfect Money. So I guess there's something for everybody.
The boosters on weekends are a good opportunity to complete some high paying offers and get a nice bonus on top. Coupons are also regularly posted on Twitter and the other social media channels and they can be redeemed in just a few seconds, so that's fast and easy.
I hope this extensive overview was helpful to some people! :)

Proof Of Work Explained

Proof Of Work Explained
https://preview.redd.it/hl80wdx61j451.png?width=1200&format=png&auto=webp&s=c80b21c53ae45c6f7d618f097bc705a1d8aaa88f
A proof-of-work (PoW) system (or protocol, or function) is a consensus mechanism that was first invented by Cynthia Dwork and Moni Naor as presented in a 1993 journal article. In 1999, it was officially adopted in a paper by Markus Jakobsson and Ari Juels and they named it as "proof of work".
It was developed as a way to prevent denial of service attacks and other service abuse (such as spam on a network). This is the most widely used consensus algorithm being used by many cryptocurrencies such as Bitcoin and Ethereum.
How does it work?
In this method, a group of users competes against each other to find the solution to a complex mathematical puzzle. Any user who successfully finds the solution would then broadcast the block to the network for verifications. Once the users verified the solution, the block then moves to confirm the state.
The blockchain network consists of numerous sets of decentralized nodes. These nodes act as admin or miners which are responsible for adding new blocks into the blockchain. The miner instantly and randomly selects a number which is combined with the data present in the block. To find a correct solution, the miners need to select a valid random number so that the newly generated block can be added to the main chain. It pays a reward to the miner node for finding the solution.
The block then passed through a hash function to generate output which matches all input/output criteria. Once the result is found, other nodes in the network verify and validate the outcome. Every new block holds the hash of the preceding block. This forms a chain of blocks. Together, they store information within the network. Changing a block requires a new block containing the same predecessor. It is almost impossible to regenerate all successors and change their data. This protects the blockchain from tampering.
What is Hash Function?
A hash function is a function that is used to map data of any length to some fixed-size values. The result or outcome of a hash function is known as hash values, hash codes, digests, or simply hashes.

The hash method is quite secure, any slight change in input will result in a different output, which further results in discarded by network participants. The hash function generates the same length of output data to that of input data. It is a one-way function i.e the function cannot be reversed to get the original data back. One can only perform checks to validate the output data with the original data.
Implementations
Nowadays, Proof-of-Work is been used in a lot of cryptocurrencies. But it was first implemented in Bitcoin after which it becomes so popular that it was adopted by several other cryptocurrencies. Bitcoin uses the puzzle Hashcash, the complexity of a puzzle is based upon the total power of the network. On average, it took approximately 10 min to block formation. Litecoin, a Bitcoin-based cryptocurrency is having a similar system. Ethereum also implemented this same protocol.
Types of PoW
Proof-of-work protocols can be categorized into two parts:-
· Challenge-response
This protocol creates a direct link between the requester (client) and the provider (server).
In this method, the requester needs to find the solution to a challenge that the server has given. The solution is then validated by the provider for authentication.
The provider chooses the challenge on the spot. Hence, its difficulty can be adapted to its current load. If the challenge-response protocol has a known solution or is known to exist within a bounded search space, then the work on the requester side may be bounded.

Source-wiki
· Solution–verification
These protocols do not have any such prior link between the sender and the receiver. The client, self-imposed a problem and solve it. It then sends the solution to the server to check both the problem choice and the outcome. Like Hashcash these schemes are also based on unbounded probabilistic iterative procedures.

Source-wiki
These two methods generally based on the following three techniques:-
CPU-bound
This technique depends upon the speed of the processor. The higher the processor power greater will be the computation.
Memory-bound
This technique utilizes the main memory accesses (either latency or bandwidth) in computation speed.
Network-bound
In this technique, the client must perform a few computations and wait to receive some tokens from remote servers.
List of proof-of-work functions
Here is a list of known proof-of-work functions:-
o Integer square root modulo a large prime
o Weaken Fiat–Shamir signatures`2
o Ong–Schnorr–Shamir signature is broken by Pollard
o Partial hash inversion
o Hash sequences
o Puzzles
o Diffie–Hellman–based puzzle
o Moderate
o Mbound
o Hokkaido
o Cuckoo Cycle
o Merkle tree-based
o Guided tour puzzle protocol
A successful attack on a blockchain network requires a lot of computational power and a lot of time to do the calculations. Proof of Work makes hacks inefficient since the cost incurred would be greater than the potential rewards for attacking the network. Miners are also incentivized not to cheat.
It is still considered as one of the most popular methods of reaching consensus in blockchains. Though it may not be the most efficient solution due to high energy extensive usage. But this is why it guarantees the security of the network.
Due to Proof of work, it is quite impossible to alter any aspect of the blockchain, since any such changes would require re-mining all those subsequent blocks. It is also difficult for a user to take control over the network computing power since the process requires high energy thus making these hash functions expensive.

Evaluating baking in a o% fee exchange vs a 10% fee standard baker

Ok, first the context:
I am an old crypto investor. I mined Bitcoin, when it was still doable with GPUs. I still have some rigs working (using Nicehash).
I participated in Tezos ICO (the only one I participated in). My only major positions are in Bircoin and Tezos, but I have several small positions in Ether, Litecoin, Nano, etc..
I am comfortable with computers (have a PhD in Computer Engineering, etc.)
I have operational accounts in several exchanges - mainly Bitstamp, Kraken and Binance.
I must start by stating that I like the new possibility of placing PoS "coins" in a good exchange and letting them handle the details of staking.
When Coinbase started that new trend, I didn't think much about it. I don't like Coinbase. Closed my account there long ago. And the fee is stupid.
But Binance with 0% fee is a different story. Binance is one of the exchanges I use at present. And 0% is a very good fee...
So This time I had to really think about what to do with my Tezos. Keep my present baker? Or send them to Binance?
And so for the substance:
At present I'm paying a fee of 10%, to avoid the hassle of baking myself. That reduces my yearly "returns" from around 6.3% (or something close to that) to some 5.7% (in fact the return is only somewhat meaningful in relation to the inflation, and even then it is debatable, but let's forget all that).
Now in Binance, which I trust for small, relatively short-term positions, I would get the full 6.3%.
The difference between having my keys, my direct control of my Tezos and using a standard for-profit baker and having them stored in an exchange baking with 0% fee is 0.6 to 0.65% yearly "return".
So, I really thought about it, but decided to leave the baking with my present baker. He works reasonably well, never failed paying my share, and I keep full control of my Tezos. In principle I will only lose them if I, myself, do something stupid.
Binance is a good exchange, but no exchange is 100% safe from some mishap.
I prefer to lose 0.6% per year to avoid the exchange-related risk, which I assume to be reasonably small, but I can't really calculate (but may well be above 1% of bankruptcy risk per year).
I believe this is the kind of reasoning everybody must make. If the risk evaluation of most Tezos holders is similar to mine, the independent bakers will survive.

AMA - Community Edition

Updated:
11) $5m buyback
12) Release of yp part 3?
13) It is allegedly possible that ICX supply can be doubled in only 4 years thanks to a whopping 20% annual token inflation
14) One of the things that got me excited about crypto was that there was no inflation. I'm a bit disappointed in Icons approach here.
15) Where is the DEX?
16) How far are we from interoperability? Am I correct in saying that interoperability is years from completion?
I'll be answering all questions to the best of my knowledge, this list will update regularly.
1) Clear description how icx will go up by benefiting from the line partnership. -> 2 or 3 practical examples.
Don't forget Unchain is a joint venture, so Unchain is ICON's company as well, their success is directly beneficial to ICON. In a recent interview w Brad, Henry also shed some light regarding this JV and that it is way beyond a simple partnership agreement https://youtu.be/paFYyt1hVWc?t=155
2) Clear description how icx will go up by building private blockchains and connecting them. -> 2 or 3 practical examples.
I answered this to someone on telegram a couple days ago. Here's my example,
"So I asked what's the use for icx with private chains. They have no reason to connect to the public chain and they have no reason to tokenzie their business."
The missing link is interoperability. The private chains need a way to communicate w each other, this is actually how the ICON project was conceived. ICONLOOP(loopchain then) offered blockchain solutions to enterprises and consortiums, but they had no way to interoperate
So I think the argument originated from, if the design paradigm is emergent for private chains to go public, or interoperate through a public chain as a common block
We've heard about those use cases and see actual implementations from U-coin vending machines to hospitals making insurance claims etc
I agree in some cases it doesn't make sense for private chains to go public, if its designing a problem to solve, lets not do that
but i'd say, a random guess, that 90%+ of the private chains have a reason to connect, much like intranet/internet
Let me try another example, we've heard the hospital/insurance too many times
Let's say there's a trade financing supply system of a large manufacturer w thousands of vendors
before their enrollment, you'll probably need to do some identity and reputation check in the public chain (common services like ID validation should readily be available as a public service, like chainID)
that will validate their legitimacy.. then next step is prolly for the vendors who need the trade financing where they need a more complex system like a stable coin to avoid volatility.. and move the money around
instead of rebuilding a coin, they could adopt a coin system within the ICON network
then what happens next.. i guess disputes w goods lost or quality problems.. again, vendors can call for a public arbitration system where there'll be a network of lawyers who specialize in cross-border disputes or arbiters to provide the service
so we need a chain of services that can be called throughout the life cycle, interoperable between private and public chains
there are plenty more use cases, but its not a hard choice to make, its definitely possible to have a common meeting point while maintaining sensitive information within their local blockchain
In the example above, nothing is tokenized, their businesses are on the private blockchain without a native coin, but they use the common services from the public like stable coins or arbitration system
3) Monthly or quartal reports on partnerships, marketing, and the tech.
You mean something like this? https://medium.com/helloiconworld/icon-3q-achievements-8c42ea798a0b
4) Opinion why korean people dont bring icx volume on korean exchanges.
I don't think even president Moon has an answer to this :P But are people really this patriotic when it comes to money? Do Americans invest in American ICOs for being made in USA? I guess some will, but this is not (and shouldn't be) the main driving force of token demand.
5) Clarification what kind of understanding we should have about this 124 teampower - are they employees with 40 hours/week working contracts or just 2 hours, cooperations partners, freelancer, what ever.
I paid a visit to the KR office a couple months back, it was like a giant coding factory running full steam. I can attest to this, they're full time employees working around the clock.
6) Roadmap - stop giving yourself room for delays and interpretations by not offering a roadmap.
My suggestion on this one is to have a % completion roadmap with change logs. I think most people are more interested in progress, less deadlines.
7) Quarterly AMAs.
Sounds good.
8) Why the hell are ICON members still advisors at Sentinel Protocol, a ICO that promoted itself using icon as blockchain and then moving to EOS.
As far as I can tell, the two teams are still in good relationships. Timing was unfortunate, SP always had their first product (uppward) scheduled to launch shortly after their fundraising. Public presale also ended a lot faster than expected (scheduled to run for a week, ended in 3 minutes). During the period ICON was migrating to mainnet V3 and doing token swap. It made sense for them to deploy on a working platform, without compromising their schedule. Their team also said that they haven't ruled out the possibility to migrate back to ICON (although I think its less likely this day).
9) Spend some money on an english translation expert for you social media appearance.
The translations (YouTube subtitles) were a bit sloppy I agree, understandable enough but they should definitely spend more time proof reading, professional presentation is a thing.
10) How much from the received ICO money/ether has been provided directly or indirectly to iconloop.
The raised ETH from ICO are barely spent, you can check on etherscan from the contribution address.
11) $5m buyback
From the key announcement by ICON foundation’s CFO Jay, the repurchase program is a pending legal matter, after consultation with law firms they’ll proceed with the buyback. https://youtu.be/keDitkWssv8?t=160
The team stated two main intentions for conducting this program,
If you read between the lines from the buyback announcement https://medium.com/helloiconworld/key-announcements-from-icon-8ea0f5a18d6f
Repurchases under the foundation’s program will be made in open market or privately negotiated transactions subject to market conditions, applicable legal requirements, and other relevant factors.
What this is saying is that, the buyback has no intention to create short term pumps, otherwise all purchases would’ve been made in the open market under a timed schedule. What this also implies is that, there won’t be a public wallet with an open schedule, to avoid legal obligations (insider trading) or unintended purposes (manipulation).
So what is to be expected? Giving a deadline won't make sense because everything can be timed, so my take is that an announcement will be made after the repurchase has been completed. I don't think anyone can take advantage of this program but will still benefit directly with $5M worth of tokens off the market supply.
12) Release of yp part 3?
This is expectedly a highly anticipated yellow paper, as it will likely outline all the details we need to know about staking. This YP however is not just a simple table with your annual returns, this is also technically far more complex than the previous two YPs.
I provided a very simplified explanation for IISS in this thread: https://twitter.com/2infiniti/status/1020141186797846529
IISS is however a lot more complicated than this, it is a full AI based incentive scoring system to explore the optimal incentive scheme to vitalize the ecosystem. On top of incentives, it is also the base metrics for governance policies (voting). Incentives are designed with token economic studies, to reinforce target behavior, based on operant conditioning principles, eg. dormant accounts, distribution schemes based on activity levels, penalties for malicious nodes etc, and it is very difficult to get right.
If you look into the WP, IISS further explored with things like mitigation of inequalities, weighted average and adjustment, efficiency of IISS, fairness of distribution, prevention of misusage and many other topics explored in depth.
The point is, this YP is very complex, and personally I’d wish the team to take as much time as it needs to get it done right. IISS will ultimately decide the overall health of our ecosystem, its sustainability and well, our passive income.
With that said, I am also with you that I’d love to see the details asap, as I have plans to build a tool similar to the Virtual Step Calculator where people can easily calculate their returns. From the announcement at least, it does look like the team is close to completion and labeled the release "soon", so let's just have a little patience and let them do all the necessary last checks.
Also as a reality check, YPs are researches that need to be formalized, implemented and iterated enough times before an official release. So please don’t expect to start staking right away when YP pt3 sees the light.
13) It is allegedly possible that ICX supply can be doubled in only 4 years thanks to a whopping 20% annual token inflation
Please go to this thread for my explanation: https://twitter.com/2infiniti/status/1060397068852748288
14) One of the things that got me excited about crypto was that there was no inflation. I'm a bit disappointed in Icons approach here.
Most crypto token issuance models can be broken down into these 3 categories
All of the above models can work in their own ways, depending on the behavior its trying to incentivize. Sustainable crypto economies are backed by a recursive loop of value transfer that all participants are incentivized to participate in. The goal is to create an incentive loop that all parties act in their own self-interest, then creating greater value.
Let’s take a look at bitcoin’s incentive loop, a simple model where mining is profitable, more miners create more security and security adds intrinsic value.
Mine bitcoin -> market dynamics decide value -> incentive to mine -> security of network increases -> more incentive to mine ←|
Augur’s case
Trusted prediction platform -> more stakes in events -> more incentive for REP holders to verify truth -> more people verifying, more trusted ←|
In ICON’s case, incentives are centered around i_score, which is a function of activities within the network. The incentive loop would look something like this
I_score rewards and governance control (votes) -> more incentive to participate in activities and governance policies -> increased network security and activity ←|
Similar incentive loop found in SCORE
SCORE staking (virtual steps) -> increased activities -> sustainable SCOREs ←|
Now for continuous issuance models, the goals are no different from other models. They want to issue tokens, just enough that it is optimal for maintaining security and encourage participations, creating a healthy incentive loop.
But can’t these models infinitely issue to a point where my money is worth next to nothing?
Yes, this is in theory possible. For Ethereum, with majority of network miners approving such change (say removing ice age), and a new Ethereum client to accommodate this change, resulting in an issuance similar to a 51% attack. Since issued ETH is also linked to the value of a single token, this will render ETH much less valuable. In practice, this is extremely unlikely to happen, as miners are financially discouraged by doing so, since they have much more to lose, just part of the game theory.
ICON’s issuance is a system implementation which depends on activities happening in the network. There are also preventive measures such as issuance upper bound and representative mitigations. I explained issuance model in full in this thread: https://twitter.com/2infiniti/status/1060397068852748288
15) Where is the DEX?
For this one hear the explanation directly from Min: https://youtu.be/tk2tZpnrI0o?t=1662
16) How far are we from interoperability? Am I correct in saying that interoperability is years from completion?
Not entirely. Interoperability will likely take a few phases to roll out, what we should be anticipating for right now is BTP (Blockchain TransfeTransmission Protocol) specification.
What is exactly is BTP?
From the abstract level, BTP creates a mechanism by which two channels may pass messages to each other. BTP assumes that multiple channels (eg. private blockchains from ICONLOOP) running on the ICON network under their own state and logic, at the same time connecting to the base channel for consensus mechanism. This is the simplest form of interoperability.
Down the road we should expect more and more advanced versions, handling threat models, connection lifecycles, asynchronous requests, and all sorts of optimization and so forth. This is enabling interoperability between blockchains one phase at a time, gradually reaching the end game of hyperconnecting the world.
So how long is this going to take?
I do not know. But the purpose of this reply is to explain that interoperability is not an on-off switch, but will likely take many phases to roll out.

Returning back to mining Monero after over 6 months. Need advice.

I have a rx580 and a ryzen 1600. It's been over 6 months so I have no clue what miner pools are good and what new miner software (was using claymore) are now here. My Aorus rx580 8gb failed to show video when I used the most up to date drives from AMD so I used the ones from the Gigabyte website and it's been fine so far.
Backstory (some insight on how I ended up mining Monero) I started mining coins about 3 years ago, with litecoin. I used minergate and with the help of their calculator I relized I could mine Monero for a way higher profit. It was during these times that I earned the majority of my Monero. I bought a 7870 to further my profits after I sold my 6950. But never sold my 0.25 XMR that I made.
Shortly thereafter my 7870 died and I was left unable to mine or game. I had little money to spare, But since the price of Monero had skyrocketed I used 0.20 to buy another used 7870.
The 7870 lasted for awhile and during that time I finally built a real gaming PC. I put a ryzen 1600 and started mining with that too. After a trip away from home I came back and started doing some cleaning. During that I heard the pc make a audible electronic sounding click. I didnt think much of it till when I went to check on it and found that the graphics card had died.
Since the mining boom was now over I set out to buy a new card. I saw an offer I could not turn down. Somone had tried to build a bitcoin rig and was selling their rx580s from it to desperately try and make money back. I got one for 100$ and proudly installed it.
Current problems: First thing I noticed was that with the most to date drives from AMD I got no video. I went to the gigabyte website and downloaded their drivers and its worked fine since. I need to figure out why this may be and if its common. It's the Aorus rx580 8gb. I also need advice on what miners I should be using with the rx580 and the Ryzen 1600 and also new pools as the one I was using, pool.monerominepool.com, shut down.

Huobi Exchange Review

A HISTORY OF HUOBI
Huobi was founded in 2013 by their current CEO and chairman, Leon Li. Li’s background includes having attended Tshingua University, specializing in Automation. Before starting the Huobi Group, Li spent time as a computer engineer at Oracle. In December of 2013, Huobi was named as the largest digital asset exchange operating in China. 2017 saw Huobi extend their limbs into Korea, Singapore, and Japan.
Currently, Huobi has headquarters of various financial sectors based in: Singapore; South Korea; Japan; Australia; Indonesia; Russia; Argentina; Thailand; and China. The company has strived to give customers not only a great exchange, but a great resource for any service one may need. Despite the many difficulties faced with Chinese government in regards to cryptocurrency laws, Huobi has managed to adapt to the changes and thrive globally, eventually branching off into various sectors including venture capital, a cryptocurrency wallet project, and a division dedicated to working with mining pools.

HUOBI'S PLATFORM
spot trading : Huobi offers several different platforms to serve any customer’s needs. For starters, Huobi offers a standard spot trading platform that operates similarly to many other spot trading platforms in the industry. The platform features a multi-timeframe chart, a depth chart, and integration with TradingView (including their tools). Customers are able to view the order book and the asset trading history, as well as their own personal order history. Limit orders, Market orders, and Stop-Limit orders are all available options for traders.
margin trading : For the trader that prefers to trade with a little more volume or risk, Huobi offers a Margin trading platform. Customers can apply for loans through Huobi to trade a greater quantity of cryptocurrencies and profit from the price spread. The original loan must be paid back, and accounts can be liquidated if the risk ratio falls below 110% (calculated as: [(Loaned Amount + Tradable Balance) Total Asset] / [(Interest Payable + Loaned Amount)] x 100%.) Traders can margin trade with Bitcoin; Ethereum; XRP; Litecoin; Bitcoin Cash; and EOS. These assets can be traded with USDT or BTC.
futures trading : Huobi also offers a Futures trading platform. While margin trading can be risky, trading contracts is said to be very high-risk. With that being said, Huobi offers Weekly, Bi-Weekly, and Quarterly contracts in Bitcoin; Ethereum Classic; Ethereum; EOS; Litecoin; Bitcoin Cash; XRP; TRX; and Bitcoin SV.
OTC(P2P) - The OTC, or over-the-counter, section of Huobi offers potential buyers and sellers a way to move large quantities of coins without exposure to the fickle exchange market. Certified merchants can register here, and slippage can be minimized by matching buyers and sellers directly instead of creating market orders.


HUOBI APPS
While you do have the online trading interface, Huobi does have computer programs and mobile apps that you can use.
I found that the PC programmes were more functional as they did not have to rely on the PC browser and were hence much faster. They also have better charting and you are in more control of your trading parameters. These programs are available on Windows and Mac devices.
However, if you are a trader that is always on the go, that is where the Huobi mobile apps come in. These were developed for the main exchange but you can switch to the derivative markets on the futures and swaps platform.
This was a pretty well designed application and you have one-touch ordering as well as some basic charting functionality. The app is available in iOS and Android and you can head on over to the respective app stores to get a sense of the feedback.


EXCHANGE SECURITY
Huobi operates a hot and cold wallet storage procedure. This means that they keep the vast amount of their coin holdings in an offline environment away from hackers. They then have a smaller percentage in “hot” wallets with multisig capability.
They also operate a decentralized server structure around the world which can ensure uptime irrespective of whether one of the servers goes down. You can think of this as effective load balancing.
Finally, they have anti DDoS measures in place. We all know that crypto exchanges are prime targets for Denial of Service attacks and it can be quite frustrating when these are perpetrated in peak market times.


IS HUOBI TRUSTWORTHY?
Huobi, like many exchanges in the space, has had, at one time, some shady history, but for the most part, has managed to maintain a clean reputation. Historically, Chinese exchanges have shown to operate in accordance with different standards, with many exchanges having to suffer at the will and whim of the Chinese government. Some of the controversy Huobi has seen in the past has been a result of this (particularly with the Chinese ban on ICO tokens). It should be noted that in 2017, the exchange did invest into “wealth-management products” using idle customer funds. This sort of activity shouldn’t be taken lightly.
However, with that being said, the exchange continues to turn over a large amount of volume. For the most part, the exchange can be considered a trustworthy platform to trade popular and exotic cryptocurrencies. This does not mean it is entirely safe to store user funds on the exchange, as the exchange (or the user funds) can be susceptible to risk at any given moment. No matter how comfortable one may be with the internet, one should always remember that the internet is not as safe as many would like to believe. Huobi does have measures in place in the unfortunate event that an account is breached, and if verifiable, the customer may be able to retrieve lost funds.
A unique feature offered on Huobi is their Official Media Authenticator. This essentially lets users enter the URL of a content channel to see if the channel is authentic. A feature like this, while seemingly simple, could save anyone from potentially losing their funds due to a scam or phishing website.


HUOBI REVIEW VERDICT
Huobi Global offers a signficant host of features to its users and has maintained its credibility over a long period of time. This is largely one of the main reasons it a ranked as a top 4 exchange by liquidity as its users trust their funds there.
After establishing itself in Asia, Huobi is trying to branch out and take on other areas of the globe which is great news for Western traders. Additionally, the Huobi prime platform could provide some great opportunities for the exchange users moving forward.

Pure PoW is DEAD

When I was 16, camping out in an airport waiting to board my first International flight to England I began chatting with a U.S. Airforce pilot who had camped up beside my group. Asking him what it was like to fly at mach speeds he replied in a very sober expression, “you have to be alert at all times. You see a mountain or some obstacle appear on the horizon, you better adjust now or you’re going to slam into it.” Maybe he was adding dramatic effect, I’ve never flown at mach speeds at low altitudes, but I never forgot it and the analogy it carries...especially so fitting for technology and progress.
This past week in cryptocurrency shined an important (and hopefully sobering) light on a “mountain” that appeared on our industries horizon...and has actually been visible to us for far too long already: Pure Proof of Work’s inevitable fate.
By pure, I mean consensus algorithms that use nothing but the original Bitcoin proof of work consensus model without updates or algorithm changes to address its weaknesses relative to the ever expanding technology used to hash it. This means Bitcoin, today’s Ethereum, Zcash, Ethereum Classic, and other coins that comprise most of the value in the top 100 cryptocurrencies. The original, unmodified form of basic PoW that most of these coins use is dead. This demise may not be fully appreciated today, but as sure as a mach-speed plane, unable to turn in time is doomed to collide with a mountain in its path, these blockchains must soon either accept their lack of security in today’s world or fork and upgrade to more effective solutions, some of which have been pioneered by smaller projects that don’t command as much hash power and therefore already had to face and address their need for extra security.
I believe it’s actually irresponsible to deny it and assume economics, hash power, market, sentiment or even self-preservation of network participants will be protection enough.
Because Bitcoin is the biggest (by market cap) of the pure PoW cryptocurrencies in existence today, I’ll establish my arguments using BTC, but the same goes for all pure PoW cryptos.
1 - Economics Bitcoin is often defended because it has the largest market cap of all cryptocurrencies and commands most of the capable hash worldwide that might be used to attack it. It is a “store of value” with proponents of this argument relying on few factors, limited supply combined with sentiment being one of the most prominent. They believe that this limited supply will inevitably drive the price up and, somehow, bitcoin will remain unequivocally secured and established.
Bitcoin has serious limitations in its adherence to the pure PoW model, and though the realities of competition has kept it free from major 51% attacks, I predict that it’s only a matter of time before it cannot command the majority of hash power that may be used to attack it. Lack of acceptance that consensus must use more than just PoW, even when checkpoints are an already accepted as necessary augmentation, leaves Bitcoin open to a catastrophic failure at some point in the future, which would affect the short term value of every cryptocurrency, even those that have addressed and solved the most glaring security challenges of a pure PoW model. Some projects have developed and are now using more advanced, more secure technology than pure PoW, and still remain fully decentralized. This is now an area where altcoins are leading, as they fill the security vacuum. With altcoins also having smart contracts and advanced currency capabilities and being potential stores of value as well, the landscape visible on the horizon in front of us looks quite different from the smooth sailing we have seen behind us with respect to projects relying on PoW and PoW alone. I’m not suggesting that Bitcoin should try to be everything that every other altcoin is becoming, but to rely on its single function as an argument of it’s security and sustainability while refraining from important technical advancements to secure its future, is foolish. The calculator is an important, valuable, and useful tool, yet people understood that it should be part of a more multifunction solution and now carry one around inside their smartphone.
The argument supporting Bitcoin’s status quo as a pure PoW blockchain and claiming it is perfect as is for whatever particular reason, is often combined with the following and includes an argument resting on self-preservation. In other words, why would anyone be nefarious and ruin their own wealth and store of value given the enormous hash power and cost it would take to attack Bitcoin? Bitcoin, then, relies on theoretical protection with idealistic boundaries.
2 - Hash Power and Hardware Capabilities This is sort of a 2 in 1 argument. Bitcoin is considered by many, the most secure blockchain in terms of pure hash power. In other words, more hash power is directed at Bitcoin than any other cryptocurrency and, there are limits to sha256d hashing speeds, economically and in hardware capabilities therefore it would be too expensive to attack Bitcoin and by the same token, make no sense to the attacker to do any wrong in this case (self preservation).
To assume technology, A: is limited to what we know now and B: will remain within these bounds for long, is just ignorant. What happens when sha256d can be hashed faster, when hardware innovations change the cost and capabilities involved? How do we know it isn’t possible now? What’s more, will Bitcoin always hold its position as the “special” coin due to its leading network hashpower that simply will never experience a world where there is enough available hash power from other sources to use for a 51% attack? The argument that Bitcoin will remain special is not an argument that its technology can protect it, especially with its roots as a project that grew from a figurative David with its sights set on the Goliath of the banking industry.
Look at the enormous hash power presently directed at Bitcoin and ask, what happens if that hash power is suddenly directed at another, less special coin, as part of a 51% attack? Is that other coin ready to defend in some way against that event? And how does this then impact Bitcoin? I would submit that at the end of the analysis, if the only thing protecting Bitcoin and its current technology from being doublespent to death is the fact that it is uniquely “special” because it is biggest, then as it unarguably becomes centralized among the largest Bitcoin participants and/or institutions, in an ironic way, refusal to improve technology could create exactly the systemic centralization that Satoshi was trying to prevent.
Even so, the idea that Bitcoin can always and forever remain the largest cryptocurrency and “special” as such, ignores historical realities that teach us differently. Remember “alta-vista”, the pre-Google winner of the search engine wars? Remember AOL? MySpace? The economics of bitcoin as people understand them today, the economics involved in mining pure PoW, the sentiment and value assigned to bitcoin and any coin now, can change as rapidly as Bitcoin emerged, even unexpectedly to the masses.
The ETC attack of only a few days ago just put the entire Cryptocurrency industry on notice. Any project without an active solution in place of immunity or at least a defense against a 51% hash attack is in trouble. I would argue that even though it will likely still take some time for market dynamics to enable an attacker to reasonably mount a 51% attack on the largest pure PoW cryptocurrency, Bitcoin, without new defense against such an attack, it is a question of when, not if.
The other day I identified a small handful of projects that have developed and are using defenses against 51% hash attacks, only one of which has a provable solution of hash attack immunity in place.
It’s important to note, any solution that can be seen as real progress over the Bitcoin protocol must be one that is decentralized. While some cryptocurrencies solve the 51% hash attack problem with a fully centralized approach, that truly misses the point of the original Bitcoin paper. Centralized databases are a different technology altogether, and implementing a centralized solution to a decentralized technology changes it entirely, in which case it’s more akin to just trying to brand your centralized database with the latest catch phrases to gain attention, support or funding.
Here’s a short list I identified of projects who have developed a defense or a complete solution to 51% hash attacks. To my knowledge, all of these solutions are now active on the respective project main networks, with the exception of Litecoin Cash, which is running on testnet at this time.:
As an industry, we need to face the fact that pure PoW is an incomplete solution to decentralized blockchain security in this age of cheap, fungible compute power. Pure PoW-only systems must evolve, and it’s time we look beyond to understand what are the best solutions that have evolved to address that fact. If you are part of a crypto project, no matter how large, you ignore the notice provided by the ETC attack at your own peril and the peril of your network participants.
My request is this… if you know of a project with a 51% hash attack solution, please provide some information below. If you totally disagree with the main point of this post, please provide a reasoned argument to prove me wrong or explain why pure PoW systems will remain viable indefinitely. As an industry, it’s time we see the blunt reality and apply innovation. Those who don’t will be reduced to interesting historical experiments.

Spock & CoinEx AMA Recap

Spock & CoinEx AMA Recap

https://preview.redd.it/1lagrcjnc9o31.png?width=1074&format=png&auto=webp&s=3136db9ca685dc17477d307df722e5b73ba80030
Spock Network is a decentralized storage platform. In the early stage, Spock Network mainly stores Proof of Capacity (POC) consensus data to effectively utilize the most suitable decentralization technology to encourage miners providing hard disk space. Recently, Spock has been growing rapidly and getting listed on four famous exchanges including CoinEx. On Sept. 19, CoinEx will launch Accelerator for Spock, allowing users to subscribe SPOK with 0.0075 USD. Besides, in order to help our users to dig more about Spock, we have invited the open source code contributor of Spock, Titian Xie, to throw an AMA among our community. Below is the recap of the AMA and enjoy your reading!

Q1: How will Spock solve the existing problems in blockchain?
A: Spock is a decentralized storage application network. Judged from the current development of blockchain technology, PoC is the only choice for a decentralized incentive mechanism in a distributed network composed of a large amount of hard disk space and bandwidth. On one hand, this solves the problem of excessive power consumption in the current mining industry, and on the other hand, it solves the problem of fair competition among a large number of existing hard-disk mining machines. At the same time, on that basis, Spock also supports Solidity smart contracts, which makes the entire ecosystem more prosperous.
Q2: Could you please say something about the team?
A: The core members of our team are all early users on Bitcointalk forum and developers of Burst. They are very familiar with the technology development trend and the details of the bottom of the blockchain technology. Even I with such a R&D background could only throw myself down at their feet in admiration. Their ideals are also very pure, that is, to make Spock a community coin like Bitcoin and Litecoin.
Q3: Community building has just started. What will you do to build the social media that remain active and continuously focus on Spock?
A: Spock is a decentralized application platform. The community also relies on spontaneous word of mouth. Since Spock was put on the test net and later on the main net, many miners and holders have spontaneously joined in to become owners, and maintained and promoted the community. The upcoming Solidity smart contracts can be carried out by polling among the holders, and members of the community will vote through the smart contract to determine the project function expansion and community governance.
Q4: Spock is a decentralized storage application platform, so what advantages does it have compared with the traditional centralized storage platform?
A: Traditional centralized storage platforms generally adopt cloud storage. Most of the data is stored on a few cloud platforms, which leads to serious centralization problems arising from data accumulation. There are also problems including higher cost, slower transfer rate, and poorer data security. The decentralized storage application platform encrypts and distributes data through a distributed network, meaning that no party, other than the data holder, could get access to the data, thus ensuring security. And one of the key issues is that the open decentralized platform can do better in protecting private data. As with the case of the assets of the digital assets of Huobi, the private key represents the ownership of the assets, and, on the decentralized storage platform, it can represent the disposition and access rights of the data.
Q5: Spock adopts the consensus mechanism of PoC. What advantages and disadvantages does PoC have compared with PoW and PoS?
A: In terms of resource usage, PoC is just between PoW and PoS, unlike PoW which consumes a lot of power, or PoS that almost costs nothing. Besides, since the core mechanism of PoC is similar to storing the “hashrate” of PoW on the hard disk, it also makes it possible for the mining equipment to mine in different projects at the same time, provided that several different projects use the same data structure.
Q6: We noticed that Spock also introduced the PoS mechanism on the basis of PoC. What is the consideration?
A: With the POS mechanism added in SPOCK, when a miner package a block, if its address balance satisfies the condition, he or she get get all the proceeds; otherwise, the proceeds will be reduced, and those that fail to meet the conditions will be destroyed. So in my opinion, developers introduce POS mechanisms to create a more equitable and sustainable ecosystem.
Q7: What will the team do to attract more developers to join the Spock ecosystem?
A: Spock is the first public link that supports the Solidity Smart Contract and has been put on the main net. It allows developers to port the DApp on the Ethernet to the network at a very low cost, while developers can design the mining and pledge mechanisms for the tokens of PoC distributed on this network.
Q8: What is the form of Spock mining? What are the conditions for miner application?
A: In SPOCK, mining is carried out through the storage device. First, you write the result of the hash calculation to the device, and reduce the huge hash calculation required in PoW algorithm by retrieving the data in the hard disk. Only a small amount of hash calculation will be required in execution stage. You can mine as long as you have storage equipment and meet the hashrate conditions. Ordinary miners just need an ordinary computer with a hard disk and access to the internet, then they need to go through hard drive mapping, download the wallet, install nodes and so on before mining.
Q9: I am a Windows phone user. How do I download a SPOK wallet?
A: At present there is only the Android version. Versions of other platforms are subject to the official arrangement.
Q10: Miners don’t know how much hashrate they have or how much they could pledge.
A: Check http://www.spockpool.com. There is a calculator to check the amount of pledges required for the time being.
Q11: Does the mining cost anything or a certain amount of SPOK tokens?
A: Now we have a market for cooperative mining. Miners can borrow tokens from owners for mortgage.
Q12: Is there a detailed tutorial for mining?
A:https://www.spockchain.org/download/SpockChain%20Mining%20Tutorial%20V1.3.2.pdf
Q13: What are the advantages compared with Lambda or such? The larger the hard disk, the higher the hashrate?
A: My suggestion is to experience the mining process on both official sites so you may understand the differences between them.
Q14: Can we use the Raspberry Pi to mine at home?
A: Yes, theoretically. Yet the weak computing power of Raspberry Pi itself may affect efficiency in hard drive mapping.

This is the end of the sharing. See you next time!
If you have any suggestions, please submit a Ticket here: https://support.coinex.com/hc/en-us/requests/new

AN INTRODUCTION TO DIGIBYTE

DigiByte

What are cryptocurrencies?
Cryptocurrencies are peer to peer technology protocols which rely on the block-chain; a system of decentralized record keeping which allows people to exchange unmodifiable and indestructible information “coins,” globally in little to no time with little to no fees – this translates into the exchange of value as these coins cannot be counterfeit nor stolen. This concept was started by Satoshi Nakamoto (allegedly a pseudonym for a single man or organization) whom described and coded Bitcoin in 2009.
What is DigiByte?
DigiByte (DGB) is a cryptocurrency like Bitcoin. It is also a decentralized applications protocol in a similar fashion to Neo or Ethereum.
DigiByte was founded and created by Jared Tate in 2014. DigiByte allows for fast (virtually instant) and low cost (virtually free) transactions. DigiByte is hard capped at 21 billion coins which will ever be mined, over a period of 21 years. DigiByte was never an ICO and was mined/created in the same way that Bitcoin or Litecoin initially were.
DigiByte is the fastest UTXO PoW scalable block-chain in the world. We’ll cover what this really means down below.
DigiByte has put forth and applied solutions to many of the problems that have plagued Bitcoin and cryptocurrencies in general – those being:
We will address these point by point in the subsequent sections.
The DigiByte Protocol
DigiByte maintains these properties through use of various technological innovations which we will briefly address below.
Why so many coins? 21 Billion
When initially conceived Bitcoin was the first of a kind! And came into the hands of a few! The beginnings of a coin such as Bitcoin were difficult, it had to go through a lot of initial growth pains which following coins did not have to face. It is for this reason among others why I believe Bitcoin was capped at 21 million; and why today it has thus secured a place as digital gold.
When Bitcoin was first invented no one knew anything about cryptocurrencies, for the inventor to get them out to the public he would have to give them away. This is how the first Bitcoins were probably passed on, for free! But then as interest grew so did the community. For them to be able to build something and create something which could go on to have actual value, it would have to go through a steady growth phase. Therefore, the control of inflation through mining was extremely important. Also, why the cap for Bitcoin was probably set so low - to allow these coins to amass value without being destroyed by inflation (from mining) in the same way fiat is today! In my mind Satoshi Nakamoto knew what he was doing when setting it at 21 million BTC and must have known and even anticipated others would take his design and build on top of it.
At DigiByte, we are that better design and capped at 21 billion. That's 1000 times larger than the supply of Bitcoin. Why though? Why is the cap on DigiByte so much higher than that of Bitcoin? Because DigiByte was conceived to be used not as a digital gold, nor as any sort of commodity, but as a real currency!
Today on planet Earth, we are approximately 7.6 billion people. If each person should want or need to use and live off Bitcoin; then equally split at best each person could only own 0.00276315789 BTC. The market cap for all the money on the whole planet today is estimated to have recently passed 80 trillion dollars. That means that each whole unit of Bitcoin would be worth approximately $3,809,523.81!
$3,809,523.81
This is of course in an extreme case where everyone used Bitcoin for everything. But even in a more conservative scenario the fact remains that with such a low supply each unit of a Bitcoin would become absurdly expensive if not inaccessible to most. Imagine trying to buy anything under a dollar!
Not only would using Bitcoin as an everyday currency be a logistical nightmare but it would be nigh impossible. For each Satoshi of a Bitcoin would be worth much, much, more than what is realistically manageable.
This is where DigiByte comes in and where it shines. DigiByte aims to be used world-wide as an international currency! Not to be hoarded in the same way Bitcoin is. If we were to do some of the same calculations with DigiByte we'd find that the numbers are a lot more reasonable.
At 7.6 billion people, each person could own 2.76315789474 DGB. Each whole unit of DGB would be worth approximately $3,809.52.
$3,809.52
This is much more manageable and remember in an extreme case where everyone used DigiByte for everything! I don't expect this to happen anytime soon, but with the supply of DigiByte it would allow us to live and transact in a much more realistic and fluid fashion. Without having to divide large numbers on our phone's calculator to understand how much we owe for that cup of coffee! With DigiByte it's simple, coffee cost 1.5 DGB, the cinema 2.8 DGB, a plane ticket 500 DGB!
There is a reason for DigiByte's large supply, and it is a good one!
Decentralisation
Decentralisation is an important concept for the block-chain and cryptocurrencies in general. This allows for a system which cannot be controlled nor manipulated no matter how large the organization in play or their intentions. DigiByte’s chain remains out of the reach of even the most powerful government. This allows for people to transact freely and openly without fear of censorship.
Decentralisation on the DigiByte block-chain is assured by having an accessible and fair mining protocol in place – this is the multi-algorithm (MultiAlgo) approach. We believe that all should have access to DigiByte whether through purchase or by mining. Therefore, DigiByte is minable not only on dedicated mining hardware such as Antminers, but also through use of conventional graphics cards. The multi-algorithm approach allows for users to mine on a variety of hardware types through use of one of the 5 mining algorithms supported by DigiByte. Those being:
Please note that these mining algorithms are modified and updated from time to time to assure complete decentralisation and thus ultimate security.
The problem with using only one mining algorithm such as Bitcoin or Litecoin do is that this allows for people to continually amass mining hardware and hash power. The more hash power one has, the more one can collect more. This leads to a cycle of centralisation and the creation of mining centres. It is known that a massive portion of all hash power in Bitcoin comes from China. This kind of centralisation is a natural tendency as it is cheaper for large organisations to set up in countries with inexpensive electricity and other such advantages which may be unavailable to the average miner.
DigiByte mitigates this problem with the use of multiple algorithms. It allows for miners with many different kinds of hardware to mine the same coin on an even playing field. Mining difficulty is set relative to the mining algorithm used. This allows for those with dedicated mining rigs to mine alongside those with more modest machines – and all secure the DigiByte chain while maintaining decentralisation.
Low Fees
Low fees are maintained in DigiByte thanks to the MultiAlgo approach working in conjunction with MultiShield (originally known as DigiShield). MultiShield calls for block difficulty readjustment between every single block on the chain; currently blocks last 15 seconds. This continuous difficulty readjustment allows us to combat any bad actors which may wish to manipulate the DigiByte chain.
Manipulation may be done by a large pool or a single entity with a great amount of hash power mining blocks on the chain; thus, increasing the difficulty of the chain. In some coins such as Bitcoin or Litecoin difficulty is readjusted every 2016 blocks at approximately 10mins each and 2mins respectively. Meaning that Bitcoin’s difficulty is readjusted about every two weeks. This system can allow for large bad actors to mine a coin and then abandon it, leaving it with a difficulty level far too high for the present hash rate – and so transactions can be frozen, and the chain stopped until there is a difficulty readjustment and or enough hash power to mine the chain. In such a case users may be faced with a choice - pay exorbitant fees or have their transactions frozen. In an extreme case the whole chain could be frozen completely for extended periods of time.
DigiByte does not face this problem as its difficulty is readjusted per block every 15 seconds. This innovation was a technological breakthrough and was adopted by several other coins in the cryptocurrency environment such as Dogecoin, Z-Cash, Ubiq, Monacoin, and Bitcoin Gold.
This difficulty readjustment along with the MultiAlgo approach allows DigiByte to maintain the lowest fees of any UTXO – PoW – chain in the world. Currently fees on the DigiByte block-chain are at about 0.0001 DGB per transaction of 100 000 DGB sent. This depends on the amount sent and currently 100 000 DGB are worth around $2000.00 with the fee being less than 0.000002 cents. It would take 500 000 transactions of 100 000 DGB to equal 1 penny’s worth. This was tested on a Ledger Nano S set to the low fees setting.
Fast transaction times
Fast transactions are ensured by the conjunctive use of the two aforementioned technology protocols. The use of MultiShield and MultiAlgo allows the mining of the DigiByte chain to always be profitable and thus there is always someone mining your transactions. MultiAlgo allows there to a greater amount of hash power spread world-wide, this along with 15 second block times allows for transactions to be near instantaneous. This speed is also ensured by the use DigiSpeed. DigiSpeed is the protocol by which the DigiByte chain will decrease block timing gradually. Initially DigiByte started with 30 second block times in 2014; which today are set at 15 seconds. This decrease will allow for ever faster and ever more transactions per block.
Robust security + The Immutable Ledger
At the core of cryptocurrency security is decentralisation. As stated before decentralisation is ensured on the DigiByte block chain by use of the MultiAlgo approach. Each algorithm in the MultiAlgo approach of DigiByte is only allowed about 20% of all new blocks. This in conjunction with MultiShield allows for DigiByte to be the most secure, most reliable, and fastest UTXO block chain on the planet. This means that DigiByte is a proof of work (PoW) block-chain where all transactional activities are stored on the immutable public ledger world-wide. In DigiByte there is no need for the Lightning protocol (although we have it) nor sidechains to scale, and thus we get to keep PoW’s security.
There are many great debates as to the robustness or cleanliness of PoW. The fact remains that PoW block-chains remain the only systems in human history which have never been hacked and thus their security is maximal.
For an attacker to divert the DigiByte chain they would need to control over 93% of all the hashrate on one algorithm and 51% of the other four. And so DigiByte is immune to the infamous 51% attack to which Bitcoin and Litecoin are vulnerable.
Moreover, the DigiByte block-chain is currently spread over 200 000 plus servers, computers, phones, and other machines world-wide. The fact is that DigiByte is one of the easiest to mine coins there is – this is greatly aided by the recent release of the one click miner. This allows for ever greater decentralisation which in turn assures that there is no single point of failure and the chain is thus virtually un-attackable.
On Chain Scalability
The biggest barrier for block-chains today is scalability. Visa the credit card company can handle around 2000 transactions per second (TPS) today. This allows them to ensure customer security and transactional rates nation-wide. Bitcoin currently sits at around 7 TPS and Litecoin at 28 TPS (56 TPS with SegWit). All the technological innovations I’ve mentioned above come together to allow for DigiByte to be the fastest PoW block-chain in the world and the most scalable.
DigiByte is scalable because of DigiSpeed, the protocol through which block times are decreased and block sizes are increased. It is known that a simple increase in block size can increase the TPS of any block-chain, such is the case with Bitcoin Cash. This is however not scalable. The reason a simple increase in block size is not scalable is because it would eventually lead to some if not a great amount of centralization. This centralization occurs because larger block sizes mean that storage costs and thus hardware cost for miners increases. This increase along with full blocks – meaning many transactions occurring on the chain – will inevitably bar out the average miner after difficulty increases and mining centres consolidate.
Hardware cost, and storage costs decrease over time following Moore’s law and DigiByte adheres to it perfectly. DigiSpeed calls for the increase in block sizes and decrease in block timing every two years by a factor of two. This means that originally DigiByte’s block sizes were 1 MB at 30 seconds each at inception in 2014. In 2016 DigiByte increased block size by two and decreased block timing by the same factor. Perfectly following Moore’s law. Moore’s law dictates that in general hardware increases in power by a factor of two while halving in cost every year.
This would allow for DigiByte to scale at a steady rate and for people to adopt new hardware at an equally steady rate and reasonable expense. Thus so, the average miner can continue to mine DigiByte on his algorithm of choice with entry level hardware.
DigiByte was one of the first block chains to adopt segregated witness (SegWit in 2017) a protocol whereby a part of transactional data is removed and stored elsewhere to decrease transaction data weight and thus increase scalability and speed. This allows us to fit more transactions per block which does not increase in size!
DigiByte currently sits at 560 TPS and could scale to over 280 000 TPS by 2035. This dwarfs any of the TPS capacities; even projected/possible capacities of some coins and even private companies. In essence DigiByte could scale worldwide today and still be reliable and robust. DigiByte could even handle the cumulative transactions of all the top 50 coins in coinmarketcap.com and still run smoothly and below capacity. In fact, to max out DigiByte’s actual maximum capacity (today at 560 TPS) you would have to take all these transactions and multiply them by a factor of 10!
Oher Uses for DigiByte
Note that DigiByte is not only to be used as a currency. Its immense robustness, security and scalability make it ideal for building decentralised applications (DAPPS) which it can host. DigiByte can in fact host DAPPS and even centralised versions which rely on the chain which are known as Digi-Apps. This application layer is also accompanied by a smart contract layer.
Thus, DigiByte could host several Crypto Kitties games and more without freezing out or increasing transaction costs for the end user.
Currently there are various DAPPS being built on the DigiByte block-chain, these are done independently of the DigiByte core team. These companies are simply using the DigiByte block-chain as a utility much in the same way one uses a road to get to work. One such example is Loly – a Tinderesque consensual dating application.
DigiByte also hosts a variety of other platform projects such as the following:
The DigiByte Foundation
As previously mentioned DigiByte was not an ICO. The DigiByte foundation was established in 2017 by founder Jared Tate. Its purpose is as a non-profit organization dedicated to supporting and developing the DigiByte block-chain.
DigiByte is a community effort and a community coin, to be treated as a public resource as water or air. Know that anyone can work on DigiByte, anyone can create, and do as they wish. It is a permissionless system which encourages innovation and creation. If you have an idea and or would like to get help on your project do not hesitate to contact the DigiByte foundation either through the official website and or the telegram developer’s channel.
For this reason, it is ever more important to note that the DigiByte foundation cannot exist without public support. And so, this is the reason I encourage all to donate to the foundation. All funds are used for the maintenance of DigiByte servers, marketing, and DigiByte development.

Hello,
I hope you’ve enjoyed my article, I originally wrote this for the reddit sub-wiki where it generally will most likely, probably not, get a lot of attention. So instead I've decided to make this sort of an introductory post, an open letter, to any newcomers to DGB or for those whom are just curious.
I tried to cover every aspect of DGB, but of course I may have forgotten something! Please leave a comment down below and tell me why you're in DGB? What convinced you? Me it's the decentralised PoW that really convinced me. Plus, just that transaction speed and virtually no fees! Made my mouth water!

Bitcoin, dogecoin. How I tried to make my fortune in 2014 with the sweat of my computer.

Bitcoin, dogecoin. How I tried to make my fortune in 2014 with the sweat of my computer.

https://preview.redd.it/mv21lvsa3do31.jpg?width=1280&format=pjpg&auto=webp&s=51bf5296a06eedc178079cf0b3ab4c3cfc44f271
Make money just by working on your computer: the rise of electronic currencies, in the wake of bitcoin, can be a little dream, especially in times of crisis. We tried the experiment. Wealth at your fingertips? Not for everybody.
Reading time: 6 min.
We have known at least since March 2013, with the soaring Bitcoin (BTC) price during the closing of Cypriot banks: electronic currencies, it has not much virtual. Since the creation of the enigmatic Satoshi Nakamoto serves as a safe haven, a playground for speculators, interests the States and even makes it possible to pay for his trip to the space where his beer, bigger world would dare to pretend that it only serves to buy prohibited substances on SilkRoad - if it ever was.
At the end of November, James Howells was mocked a lot, this Brit, caught in a household frenzy, inadvertently threw a hard disk containing 7,500 bitcoins, the equivalent of 4.8 million euros. A small fortune now lost in the depths of the Docksway dump near Newport. Nevertheless, before causing the consternation of the global Internet, Jamie still had the nose to undermine the BTC at a time when the experience mobilized a handful of hardcore geeks.
Since the rise (sawtooth) bitcoin, each unit currently weighs more than 800 dollars, nearly thirty cryptocurrencies have emerged. Is it possible, this year again, to let this promising, volatile and risky train pass, or to fall into
  1. Choose your electronic motto.
  2. All are based on the same principle: to summarize (very) big features [1], the issuance of money is governed by an algorithm, and the new corners put in circulation reward the resolution, by participants in a network of peer and mathematical problems, including the validation and archiving of transactions, which are public [2]. Mining a cryptocurrency is like putting the computing power of your computer in the service of the network.
  3. Since the program is decreasing [3], the mining becomes more and more difficult with time (and with the increase of the number of participants): to hope to make his pelote via the only computational activity, one must either have to at its disposal a large fleet of machines, to be a miner from the first hour. Exit the bitcoin, long since out of the reach of a personal computer.
  4. I similarly gave up the litecoin and peercoin, already well launched (they date respectively 2011 and 2012), to set my heart on one of the most recent currencies - and certainly the hippest of the moment: the dogecoin.
  5. As its name suggests, the cryptocurrency favorite Shiba Inus from around the world is a tribute to the Doge, one of the most famous memes of 2013, with its captions in Comic Sans, the font most sorry for the web. A geek joke, therefore, except that - the unfathomable mysteries of the Internet - its value jumped 900% in the third week of December, and she suffered a Christmas robbery online.
  6. Admittedly, at the time when these lines are written, the dogecoin caps at 0.00023 dollars [4] - its quite ridiculous (and quite depressing), but even if you bet on the future, so much to go frankly.
  7. 2. The hands in the engine the billboard.
  8. From there, things get tough (a little). Installing an electronic purse on ones computer is not very complicated (the software is available for Windows, MacOS, Android or, for the more adventurous, on a repository to compile under Linux). It is also possible to use an online wallet, but it is more risky (except, perhaps, when one is called James Howells). When opened for the first time, the purse automatically synchronizes with the Dogecoin network (be careful, it can be long), which gives you a payment address (we can generate more later).
  9. The two most common ways to undermine electronic money are to use the computing power of the computers microprocessor (CPU) or, more efficiently, that of the graphics card processor (GPU). In the first case, the program is simple to install; in the second, it is necessary to choose the most adapted to its material [5]. There are, thankfully, a lot of online tutorials. Still, to operate the corner board requires in all cases to trade the comfort of the GUI for aridity, so confusing to the layman, command lines - we have nothing for nothing.
  10. Finally, at work alone, we prefer collaboration. Mining is best done in groups, or rather in pool: it distributes the gains, of course, but also the difficulty. For the dogecoin as for all the crypto-currencies, the pools are numerous. A quick tour of a dedicated section of the Reddit community site can help you make your choice.
  11. 3. Extension of the field of struggle.
  12. And after? After, we can rest, since it is the machine that works. But the truth of a cryptocurrency - even at the exceptionally high LOL and LOL rates of the Shiba Inu - is cruel and brutal: not all computers are equal. Or rather, some are more equal than others. For while you heat your CPU or your graphics card to grapple some unfortunate corners, others will sweep the game thanks to specialized integrated circuits, computing capabilities much higher.
  13. If the game of buying and reselling corners is basically just another stock exchange mechanism, less the intervention of the central banks - what is at stake, and the big political question they ask: are we certain to prefer speculation pure and perfect to monetary policies, however questionable they may be? -, production, it is the law of the strongest (in calculation). There are even lethal weapons at $ 10,000 each, with which your processors are like mosquitoes in front of an A bomb.
  14. And if you think it does not matter because after all, it does not cost you anything, think again: the components, like humans, wear out faster when they work at full speed, and the bill of electricity can quickly grow. The profitability of the case is anything but certain, as evidenced by the results of online calculators. (Needless to say, our laughing dogecoin does not stand up to this kind of simulation.)
  15. Much more boring, from a collective point of view: the carbon footprint, current and above all expected, of electronic currencies worries more and more. Last spring, Bloomberg estimated that the energy consumption of the Bitcoin network was equivalent to that of 31,000 US households. Not sure, according to the site, that their emission is less damaging to the environment than have been some physical currencies.
  16. For exciting to analyze that is the emergence of cryptocurrencies, it is better to ask now about their cost, economic and ecological. To see it as a potential source of income, except for being a very early adopter with a hollow nose, an individual with a lot of computational capital or a clever trader, you have to make a point.
  17. If the recurrent comparison with the famous Ponzi pyramid [6] is discussed (after all, the decentralized currencies do not make promises), remains that, as long as the value does not collapse, the system benefits mainly to the first entrants - except James Howells.
  18. As the Bitcoin.fr site aptly states: all this is just an experiment, invest only the time and money you can afford to lose. LOLs love was not a worse reason than another to experiment, so I finally submitted my laptop to four days and three nights of intense activity, which makes me happy. owner of a good half a thousand dogecoins. Either the equivalent of 0.115 dollar, or 0.08 euro. It is obviously not worth the electricity consumed to generate them, it increases my carbon footprint, but it amuses my entourage. But laughter is, as everyone knows, a safe bet in times of crisis, less volatile than a real bitcoin.
  19. And then, after all, you never know.
  20. Amaelle Guiton.
  21. 1. For explanations more provided (the case is quite complex), refer, for example, to the series of very detailed notes devoted to blogger Turblog.
  22. 2. And as such, searchable by everyone. It is the identity of the users that is not known, unless they reveal it, hence the reputation of anonymity (relative, therefore) cryptocurrencies.
  23. 3. In the case of bitcoin, the maximum of 21 million units should be reached around 2140.
  24. 4. For a day-to-day follow-up, see the CoinMarketCap site which lists the exchange rates of crypto-currencies, based on the dollar value of bitcoin.
  25. 5. We discover then, unfortunately, that some graphics cards do not allow the mining. This is the case for the author of these lines, reduced to working in conditions of extreme computer deprivation.
  26. 6. Comparison which is at the heart of a hilarious note on the ponzicoin, signed by the economic journalist Matthew OBrien, on The Atlantic (to read if you intend seriously to invest in the dogecoin).
