Why Osana takes so long? (Programmer's point of view on current situation)
I decided to write a comment about «Why Osana takes so long?» somewhere and what can be done to shorten this time. It turned into a long essay. Here's TL;DR of it:
The cost of never paying down this technical debt is clear; eventually the cost to deliver functionality will become so slow that it is easy for a well-designed competitive software product to overtake the badly-designed software in terms of features. In my experience, badly designed software can also lead to a more stressed engineering workforce, in turn leading higher staff churn (which in turn affects costs and productivity when delivering features). Additionally, due to the complexity in a given codebase, the ability to accurately estimate work will also disappear. Junade Ali, Mastering PHP Design Patterns (2016)
Longer version: I am not sure if people here wanted an explanation from a real developer who works with C and with relatively large projects, but I am going to do it nonetheless. I am not much interested in Yandere Simulator nor in this genre in general, but this particular development has a lot to learn from for any fellow programmers and software engineers to ensure that they'll never end up in Alex's situation, especially considering that he is definitely not the first one to got himself knee-deep in the development hell (do you remember Star Citizen?) and he is definitely not the last one. On the one hand, people see that Alex works incredibly slowly, equivalent of, like, one hour per day, comparing it with, say, Papers, Please, the game that was developed in nine months from start to finish by one guy. On the other hand, Alex himself most likely thinks that he works until complete exhaustion each day. In fact, I highly suspect that both those sentences are correct! Because of the mistakes made during early development stages, which are highly unlikely to be fixed due to the pressure put on the developer right now and due to his overall approach to coding, cost to add any relatively large feature (e.g. Osana) can be pretty much comparable to the cost of creating a fan game from start to finish. Trust me, I've seen his leaked source code (don't tell anybody about that) and I know what I am talking about. The largest problem in Yandere Simulator right now is its super slow development. So, without further ado, let's talk about how «implementing the low hanging fruit» crippled the development and, more importantly, what would have been an ideal course of action from my point of view to get out. I'll try to explain things in the easiest terms possible.
else if's and lack any sort of refactoring in general
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. Antoine de Saint-Exupéry
This is why refactoring — activity of rewriting your old code so it does the same thing, but does it quicker, in a more generic way, in less lines or simpler — is so powerful. In my experience, you can only keep one module/class/whatever in your brain if it does not exceed ~1000 lines, maybe ~1500. Splitting 17000-line-long class into smaller classes probably won't improve performance at all, but it will make working with parts of this class way easier. Is it too late now to start refactoring? Of course NO: better late than never.
If you think that you wrote this code, so you'll always easily remember it, I have some bad news for you: you won't. In my experience, one week and that's it. That's why comments are so crucial. It is not necessary to put a ton of comments everywhere, but just a general idea will help you out in the future. Even if you think that It Just Works™ and you'll never ever need to fix it. Time spent to write and debug one line of code almost always exceeds time to write one comment in large-scale projects. Moreover, the best code is the code that is self-evident. In the example above, what the hell does (float) 6 mean? Why not wrap it around into the constant with a good, self-descriptive name? Again, it won't affect performance, since C# compiler is smart enough to silently remove this constant from the real code and place its value into the method invocation directly. Such constants are here for you. I rewrote my code above a little bit to illustrate this. With those comments, you don't have to remember your code at all, since its functionality is outlined in two tiny lines of comments above it. Moreover, even a person with zero knowledge in programming will figure out the purpose of this code. It took me less than half a minute to write those comments, but it'll probably save me quite a lot of time of figuring out «what was I thinking back then» one day. Is it too late now to start adding comments? Again, of course NO. Don't be lazy and redirect all your typing from «debunk» page (which pretty much does the opposite of debunking, but who am I to judge you here?) into some useful comments.
This is often neglected, but consider the following. You wrote some code, you ran your game, you saw a new bug. Was it introduced right now? Is it a problem in your older code which has shown up just because you have never actually used it until now? Where should you search for it? You have no idea, and you have one painful debugging session ahead. Just imagine how easier it would be if you've had some routines which automatically execute after each build and check that environment is still sane and nothing broke on a fundamental level. This is called unit testing, and yes, unit tests won't be able to catch all your bugs, but even getting 20% of bugs identified at the earlier stage is a huge boon to development speed. Is it too late now to start adding unit tests? Kinda YES and NO at the same time. Unit testing works best if it covers the majority of project's code. On the other side, a journey of a thousand miles begins with a single step. If you decide to start refactoring your code, writing a unit test before refactoring will help you to prove to yourself that you have not broken anything without the need of running the game at all.
This is basically pretty self-explanatory. You set this thing once, you forget about it. Static code analyzer is another «free estate» to speed up the development process by finding tiny little errors, mostly silly typos (do you think that you are good enough in finding them? Well, good luck catching x << 4; in place of x <<= 4; buried deep in C code by eye!). Again, this is not a silver bullet, it is another tool which will help you out with debugging a little bit along with the debugger, unit tests and other things. You need every little bit of help here. Is it too late now to hook up static code analyzer? Obviously NO.
Say, you want to build Osana, but then you decided to implement some feature, e.g. Snap Mode. By doing this you have maybe made your game a little bit better, but what you have just essentially done is complicated your life, because now you should also write Osana code for Snap Mode. The way game architecture is done right now, easter eggs code is deeply interleaved with game logic, which leads to code «spaghettifying», which in turn slows down the addition of new features, because one has to consider how this feature would work alongside each and every old feature and easter egg. Even if it is just gazing over one line per easter egg, it adds up to the mess, slowly but surely. A lot of people mention that developer should have been doing it in object-oritented way. However, there is no silver bullet in programming. It does not matter that much if you are doing it object-oriented way or usual procedural way; you can theoretically write, say, AI routines on functional (e.g. LISP)) or even logical language if you are brave enough (e.g. Prolog). You can even invent your own tiny programming language! The only thing that matters is code quality and avoiding the so-called shotgun surgery situation, which plagues Yandere Simulator from top to bottom right now. Is there a way of adding a new feature without interfering with your older code (e.g. by creating a child class which will encapsulate all the things you need, for example)? Go for it, this feature is basically «free» for you. Otherwise you'd better think twice before doing this, because you are going into the «technical debt» territory, borrowing your time from the future by saying «I'll maybe optimize it later» and «a thousand more lines probably won't slow me down in the future that much, right?». Technical debt will incur interest on its own that you'll have to pay. Basically, the entire situation around Osana right now is just a huge tale about how just «interest» incurred by technical debt can control the entire project, like the tail wiggling the dog. I won't elaborate here further, since it'll take me an even larger post to fully describe what's wrong about Yandere Simulator's code architecture. Is it too late to rebuild code architecture? Sadly, YES, although it should be possible to split Student class into descendants by using hooks for individual students. However, code architecture can be improved by a vast margin if you start removing easter eggs and features like Snap Mode that currently bloat Yandere Simulator. I know it is going to be painful, but it is the only way to improve code quality here and now. This will simplify the code, and this will make it easier for you to add the «real» features, like Osana or whatever you'd like to accomplish. If you'll ever want them back, you can track them down in Git history and re-implement them one by one, hopefully without performing the shotgun surgery this time.
Again, I won't be talking about the performance, since you can debug your game on 20 FPS as well as on 60 FPS, but this is a very different story. Yandere Simulator is huge. Once you fixed a bug, you want to test it, right? And your workflow right now probably looks like this:
Fix the code (unavoidable time loss)
Rebuild the project (can take a loooong time)
Load your game (can take a loooong time)
Test it (unavoidable time loss, unless another bug has popped up via unit testing, code analyzer etc.)
And you can fix it. For instance, I know that Yandere Simulator makes all the students' photos during loading. Why should that be done there? Why not either move it to project building stage by adding build hook so Unity does that for you during full project rebuild, or, even better, why not disable it completely or replace with «PLACEHOLDER» text for debug builds? Each second spent watching the loading screen will be rightfully interpreted as «son is not coding» by the community. Is it too late to reduce loading times? Hell NO.
Or any other continuous integration tool. «Rebuild a project» can take a long time too, and what can we do about that? Let me give you an idea. Buy a new PC. Get a 32-core Threadripper, 32 GB of fastest RAM you can afford and a cool motherboard which would support all of that (of course, Ryzen/i5/Celeron/i386/Raspberry Pi is fine too, but the faster, the better). The rest is not necessary, e.g. a barely functional second hand video card burned out by bitcoin mining is fine. You set up another PC in your room. You connect it to your network. You set up ramdisk to speed things up even more. You properly set up Jenkins) on this PC. From now on, Jenkins cares about the rest: tracking your Git repository, (re)building process, large and time-consuming unit tests, invoking static code analyzer, profiling, generating reports and whatever else you can and want to hook up. More importantly, you can fix another bug while Jenkins is rebuilding the project for the previous one et cetera. In general, continuous integration is a great technology to quickly track down errors that were introduced in previous versions, attempting to avoid those kinds of bug hunting sessions. I am highly unsure if continuous integration is needed for 10000-20000 source lines long projects, but things can be different as soon as we step into the 100k+ territory, and Yandere Simulator by now has approximately 150k+ source lines of code. I think that probably continuous integration might be well worth it for Yandere Simulator. Is it too late to add continuous integration?NO, albeit it is going to take some time and skills to set up.
Stop caring about the criticism
Stop comparing Alex to Scott Cawton. IMO Alex is very similar to the person known as SgtMarkIV, the developer of Brutal Doom, who is also a notorious edgelord who, for example, also once told somebody to kill himself, just like… However, being a horrible person, SgtMarkIV does his job. He simply does not care much about public opinion. That's the difference.
MintDice is proud to bring you the fourth part of the CryptoSmarts series, a 100% unbiased/non-affiliate paid article set that will focus on relatively simple ways you can boost your privacy, take power away from overbearing governments and corporations while also doing relative good for society all at the same time with minimal effort. Rest assured that anything suggested here is solely for your own benefit. In this article, we'll take a deep dive into password managers, which applications to go for, how to optimize your password managers and which ones to avoid. It's of increasing importance for all users to adopt a password manager because commonly used passwords and repeated use of log-in + password combinations are the two weakest points in any normal individual's security online. Meanwhile, memorizing dozens of unique and complex passwords is beyond the scope of what most people can do, especially long term. Thus password managers have been created as a way to store multiple passwords into a single file that can help ensure your security and privacy online. For a little encouragement, we'll share the now extremely famous dialogue between Edward Snowden and John Oliver talking about passwords. As should be painfully obvious by now, password managers are one of the best solutions to this entire dilemma. https://preview.redd.it/ribbtjwz1it51.png?width=1000&format=png&auto=webp&s=3c3a9a31bdb8c4f9ec83bea98638fec5dd78b38f
PASSWORD MANAGER BASICS
We should first note that not all password managers are created the same as we've noted with software across all of our other articles. By and large, we'll be looking for similar characteristics in our password managers as we would our other software which includes open sourced software protocols and best software security practices. And when it comes to Bitcoin, cryptocurrency and your entire life's work on the internet, there is a lot at stake here. I'd argue that it is more important for password managers than for any other application to make sure to get this one correct since it will have your entire livelihood on the line. The very amazing thing with demanding open sourced software for your password manager is that it by definition will also be free at the most basic level. This is because if it weren't, all it would take would be someone to fork over a program to make it free. So you are in a sense getting the best of both worlds here; a free software that is also of the highest quality. Meanwhile, ironically, many of the more commonly known password managers like Dashlane or Lastpass use closed source software and often charge fees to use their service. Funnily enough, Lastpass, the password manager itself, was actually formerly hacked in the past. One could argue this at least in part had to do with it's closed source software since having open sourced software at least in part makes software more secure. In short, do not used these closed source services that are frequently advertised for on the web as they are detrimental to you in more ways than one.
RECOMMENDED BEST PASSWORD MANAGERS
Bitwarden is our first recommendation. Bitwarden is truly one of the all time greats by approaching password management on the individual, team and even enterprise level to create a one size fits all solution. Bitwarden is compatible on virtually all devices out there from all desktops to mobile devices and so forth. Additionally, while they offer a centralized cloud service for free, Bitwarden is also set up to allow you to run your own private server to keep your own key base entirely under your own control, fully encrypted. https://preview.redd.it/zmlkf5d12it51.jpg?width=770&format=pjpg&auto=webp&s=02998b777d05ab00557a97c616a4b0d505b324aa Next up we have KeePassXC which is a fork of one of the longest standing password managers in existence, formerly known as KeePass that halted a lot of it's ongoing development some time ago. KeePassXC was created as a locally held password manager application that could work across platforms. Unlike Bitwarden where your key file is held in cloud storage, KeePassXC is simply a program client and a local file that you must maintain and backup yourself. This has some pros and cons. The good news is that you have full control of everything related to KeePassXC as the program under most situations will not be talking to any online server which could expose private or sensitive information. The bad news is that if you ever were to lose control of your key file, you are completely out of luck. For this reason, it's imperative to back up your encrypted key file in multiple locations to protect against what would be catastrophic loss. You can do this with USB drives, e-mail accounts, cloud storage, safe deposit boxes or a whole host of other creative solutions that you might come up with. The final recommended option is LessPass. LessPass is very interesting technology because it is a no-knowledge password manager. By inputting a few pieces of information which could be a master password in conjunction with an e-mail address or user name, a password is automatically attached to any URL address. It will simply cross all of these pieces of information via PBKDF2 and SHA-256 to produce random yet consistent outputs for any of your web browsing. The advantage of this program is that it is extremely light weight, and so long as you can remember your e-mail address, account name and master password, you can now gain full access to everything around the internet without the need of any files. The downside is some level of control over password flexibility since the passwords are automatically generated for you. In summation of these three options, BitWarden is the best overall password manager for most people's use cases. Meanwhile, LessPass is probably best suited for the most casual user who contains fewer accounts across the internet and wants something extremely simple and easy to use. Lastly, KeePassXC, will be the ultimate in privacy password manager technology and is best suited for those that are prepared to take the extra steps to ensure their key file is kept up to date as the months and years tick by. https://preview.redd.it/r4icjup22it51.jpg?width=1920&format=pjpg&auto=webp&s=622cf1b967ec5622e3feb2b49e5ac29917629cdf
BEST PRACTICES WITH YOUR NEW PASSWORD MANAGER
Once you have chosen a password manager from the above list, it will be important to change all of your account passwords one by one to incorporate it into your new system. This will help you get away from your commonly used log-in and password combinations and over to your new, more secure and robust set up. With your new set up, if you have a key file to back up, you must now start getting in the habit of doing so, especially after major or important changes to your password manager. Or if you wish to use BItWarden with a private cloud server, make sure that that is fully set up and running. Generally speaking, when choosing password length from your password manager for standard and robust security, 25 random characters, letters (and symbols if you wish, but they aren't necessary), is mostly considered to be uncrackable. This is because while every password is in theory beatable, it takes dramatically more computational energy over time to figure out what your password is, and at some point, it becomes unreasonable. That said, NSA grade security often holds itself up to 50 random characters which is considered to be unbreakable even on a government wide scale. On that same token, you'll have to use a master password for your password manager. Given that you only need to know one password, it will now be extremely important to make this a very good password. Because a password that you need to remember most likely won't (or perhaps shouldn't) be completely random so that it's easy to remember, it should, at the very least, be long. I would suggest making sure that you come up with a master password that is at least 40 characters long or 125 bits of information. To check out how many bits of entropy your master password is, you can type it into the password field of KeePassXC and it will tell you roughly how secure your master password is. While 40 characters may seem like a lot, do keep in mind that this is now the only gateway between yourself and all of your access keys to all of your accounts held on this account. Bits of Entropy Example on KeePassXC Finally, it is worth investing in a YubiKey or similar 2-FA device if you can get one. This can apply to BitWarden and KeePassXC. With the normal password managers, a hacker will need access to not only your password but also your key file in order to have free reign over all of your accounts. However, a sophisticated hacker that has full access to your device with a keylogger could ultimately, in theory, compromise your full set up, and this would be disastrous for you. Fortunately, this can be resolved by buying and activating a Yubikey or other such device. The Yubikey example requires that a Yubikey, with a private key that you set up for your password manager, is present to access your database. Therefore, even if a hacker were to obtain your key file and your master password, they still won't be able gain access to your account. As a precaution, however, if you lose access to your Yubikey and/or private key, you too, will be locked out. Therefore, it is important to keep your Yubikey backed up and to keep extra copies available.
Owning Bitcoin or other cryptocurrencies comes with a lot of responsibility if you want to minimize risk. As does maintaining a strong hack-resistant presence online. One of the best defenses you can make is by implementing a password manager. Similar to the previous CryptoSmarts articles that we have written prior, it will take some small amount of set up work to get fully acclimated to your new system, but you'll thank yourself down the road that you have done this. And the sooner you start, the better, as things will only continue to get more complex, with more risk factors at play as the internet plays an ever increasing role in all of our day to day lives. Finally, while the article is current as of the writing of the article, it will undoubtedly lose merit over time. Be sure to check if everything in this article is up to date or that any password manager that you select from this article continues development or continues to abide by the proper best practice principles. If you enjoyed this article, we would encourage you to check out our other previous CryptoSmarts articles discussing private e-mails, secure messenger applications and proper web browsers.
New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

How To End The Cryptocurrency Exchange "Wild West" Without Crippling Innovation
In case you haven't noticed the consultation paper, staff notice, and report on Quadriga, regulators are now clamping down on Canadian cryptocurrency exchanges. The OSC and other regulatory bodies are still interested in industry feedback. They have not put forward any official regulation yet. Below are some ideas/insights and a proposed framework.
Typical securities frameworks will cost Canadians millions of dollars (ie Sarbanes-Oxley estimated at $5m USD/yr per firm). Implementation costs of this proposal are significantly cheaper.
Canadians can maintain a diverse set of exchanges, multiple viable business models are still fully supported, and innovation is encouraged while keeping Canadians safe.
Many of you have limited time to read the full proposal, so here are the highlights:
Effective standards to prevent both internal and external theft. Exchange operators are trained and certified, and have a legal responsibility to users.
Regular Transparent Audits
Provides visibility to Canadians that their funds are fully backed on the exchange, while protecting privacy and sensitive platform information.
Establishment of basic insurance standards/strategy, to expand over time. Removing risk to exchange users of any hot wallet theft.
Background and Justifications
Cold Storage Custody/Management After reviewing close to 100 cases, all thefts tend to break down into more or less the same set of problems: • Funds stored online or in a smart contract, • Access controlled by one person or one system, • 51% attacks (rare), • Funds sent to the wrong address (also rare), or • Some combination of the above. For the first two cases, practical solutions exist and are widely implemented on exchanges already. Offline multi-signature solutions are already industry standard. No cases studied found an external theft or exit scam involving an offline multi-signature wallet implementation. Security can be further improved through minimum numbers of signatories, background checks, providing autonomy and legal protections to each signatory, establishing best practices, and a training/certification program. The last two transaction risks occur more rarely, and have never resulted in a loss affecting the actual users of the exchange. In all cases to date where operators made the mistake, they've been fully covered by the exchange platforms. • 51% attacks generally only occur on blockchains with less security. The most prominent cases have been Bitcoin Gold and Ethereum Classic. The simple solution is to enforce deposit limits and block delays such that a 51% attack is not cost-effective. • The risk of transactions to incorrect addresses can be eliminated by a simple test transaction policy on large transactions. By sending a small amount of funds prior to any large withdrawals/transfers as a standard practice, the accuracy of the wallet address can be validated. The proposal covers all loss cases and goes beyond, while avoiding significant additional costs, risks, and limitations which may be associated with other frameworks like SOC II. On The Subject of Third Party Custodians Many Canadian platforms are currently experimenting with third party custody. From the standpoint of the exchange operator, they can liberate themselves from some responsibility of custody, passing that off to someone else. For regulators, it puts crypto in similar categorization to oil, gold, and other commodities, with some common standards. Platform users would likely feel greater confidence if the custodian was a brand they recognized. If the custodian was knowledgeable and had a decent team that employed multi-sig, they could keep assets safe from internal theft. With the right protections in place, this could be a great solution for many exchanges, particularly those that lack the relevant experience or human resources for their own custody systems. However, this system is vulnerable to anyone able to impersonate the exchange operators. You may have a situation where different employees who don't know each other that well are interacting between different companies (both the custodian and all their customers which presumably isn't just one exchange). A case study of what can go wrong in this type of environment might be Bitpay, where the CEO was tricked out of 5000 bitcoins over 3 separate payments by a series of emails sent legitimately from a breached computer of another company CEO. It's also still vulnerable to the platform being compromised, as in the really large $70M Bitfinex hack, where the third party Bitgo held one key in a multi-sig wallet. The hacker simply authorized the withdrawal using the same credentials as Bitfinex (requesting Bitgo to sign multiple withdrawal transactions). This succeeded even with the use of multi-sig and two heavily security-focused companies, due to the lack of human oversight (basically, hot wallet). Of course, you can learn from these cases and improve the security, but so can hackers improve their deception and at the end of the day, both of these would have been stopped by the much simpler solution of a qualified team who knew each other and employed multi-sig with properly protected keys. It's pretty hard to beat a human being who knows the business and the typical customer behaviour (or even knows their customers personally) at spotting fraud, and the proposed multi-sig means any hacker has to get through the scrutiny of 3 (or more) separate people, all of whom would have proper training including historical case studies. There are strong arguments both for and against using use of third party custodians. The proposal sets mandatory minimum custody standards would apply regardless if the cold wallet signatories are exchange operators, independent custodians, or a mix of both. On The Subject Of Insurance ShakePay has taken the first steps into this new realm (congratulations). There is no question that crypto users could be better protected by the right insurance policies, and it certainly feels better to transact with insured platforms. The steps required to obtain insurance generally place attention in valuable security areas, and in this case included a review from CipherTrace. One of the key solutions in traditional finance comes from insurance from entities such as the CDIC. However, historically, there wasn't found any actual insurance payout to any cryptocurrency exchange, and there are notable cases where insurance has not paid. With Bitpay, for example, the insurance agent refused because the issue happened to the third party CEO's computer instead of anything to do with Bitpay itself. With the Youbit exchange in South Korea, their insurance claim was denied, and the exchange ultimately ended up instead going bankrupt with all user's funds lost. To quote Matt Johnson in the original Lloyd's article: “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.” ShakePay's insurance was only reported to cover their cold storage, and “physical theft of the media where the private keys are held”. Physical theft has never, in the history of cryptocurrency exchange cases reviewed, been reported as the cause of loss. From the limited information of the article, ShakePay made it clear their funds are in the hands of a single US custodian, and at least part of their security strategy is to "decline to confirm the custodian’s name on the record". While this prevents scrutiny of the custodian, it's pretty silly to speculate that a reasonably competent hacking group couldn't determine who the custodian is. A far more common infiltration strategy historically would be social engineering, which has succeeded repeatedly. A hacker could trick their way into ShakePay's systems and request a fraudulent withdrawal, impersonate ShakePay and request the custodian to move funds, or socially engineer their way into the custodian to initiate the withdrawal of multiple accounts (a payout much larger than ShakePay) exploiting the standard procedures (for example, fraudulently initiating or override the wallet addresses of a real transfer). In each case, nothing was physically stolen and the loss is therefore not covered by insurance. In order for any insurance to be effective, clear policies have to be established about what needs to be covered. Anything short of that gives Canadians false confidence that they are protected when they aren't in any meaningful way. At this time, the third party insurance market does not appear to provide adequate options or coverage, and effort is necessary to standardize custody standards, which is a likely first step in ultimately setting up an insurance framework. A better solution compared to third party insurance providers might be for Canadian exchange operators to create their own collective insurance fund, or a specific federal organization similar to the CDIC. Such an organization would have a greater interest or obligation in paying out actual cases, and that would be it's purpose rather than maximizing it's own profit. This would be similar to the SAFU which Binance has launched, except it would cover multiple exchanges. There is little question whether the SAFU would pay out given a breach of Binance, and a similar argument could be made for a insurance fund managed by a collective of exchange operators or a government organization. While a third party insurance provider has the strong market incentive to provide the absolute minimum coverage and no market incentive to payout, an entity managed by exchange operators would have incentive to protect the reputation of exchange operators/the industry, and the government should have the interest of protecting Canadians. On The Subject of Fractional Reserve There is a long history of fractional reserve failures, from the first banks in ancient times, through the great depression (where hundreds of fractional reserve banks failed), right through to the 2008 banking collapse referenced in the first bitcoin block. The fractional reserve system allows banks to multiply the money supply far beyond the actual cash (or other assets) in existence, backed only by a system of debt obligations of others. Safely supporting a fractional reserve system is a topic of far greater complexity than can be addressed by a simple policy, and when it comes to cryptocurrency, there is presently no entity reasonably able to bail anyone out in the event of failure. Therefore, this framework is addressed around entities that aim to maintain 100% backing of funds. There may be some firms that desire but have failed to maintain 100% backing. In this case, there are multiple solutions, including outside investment, merging with other exchanges, or enforcing a gradual restoration plan. All of these solutions are typically far better than shutting down the exchange, and there are multiple cases where they've been used successfully in the past. Proof of Reserves/Transparency/Accountability Canadians need to have visibility into the backing on an ongoing basis. The best solution for crypto-assets is a Proof of Reserve. Such ideas go back all the way to 2013, before even Mt. Gox. However, no Canadian exchange has yet implemented such a system, and only a few international exchanges (CoinFloor in the UK being an example) have. Many firms like Kraken, BitBuy, and now ShakePay use the Proof of Reserve term to refer to lesser proofs which do not actually cryptographically prove the full backing of all user assets on the blockchain. In order for a Proof of Reserve to be effective, it must actually be a complete proof, and it needs to be understood by the public that is expected to use it. Many firms have expressed reservations about the level of transparency required in a complete Proof of Reserve (for example Kraken here). While a complete Proof of Reserves should be encouraged, and there are some solutions in the works (ie TxQuick), this is unlikely to be suitable universally for all exchange operators and users. Given the limitations, and that firms also manage fiat assets, a more traditional audit process makes more sense. Some Canadian exchanges (CoinSquare, CoinBerry) have already subjected themselves to annual audits. However, these results are not presently shared publicly, and there is no guarantee over the process including all user assets or the integrity and independence of the auditor. The auditor has been typically not known, and in some cases, the identity of the auditor is protected by a NDA. Only in one case (BitBuy) was an actual report generated and publicly shared. There has been no attempt made to validate that user accounts provided during these audits have been complete or accurate. A fraudulent fractional exchange, or one which had suffered a breach they were unwilling to publicly accept (see CoinBene), could easily maintain a second set of books for auditors or simply exclude key accounts to pass an individual audit. The proposed solution would see a reporting standard which includes at a minimum - percentage of backing for each asset relative to account balances and the nature of how those assets are stored, with ownership proven by the auditor. The auditor would also publicly provide a "hash list", which they independently generate from the accounts provided by the exchange. Every exchange user can then check their information against this public "hash list". A hash is a one-way form of encryption, which fully protects the private information, yet allows anyone who knows that information already to validate that it was included. Less experienced users can take advantage of public tools to calculate the hash from their information (provided by the exchange), and thus have certainty that the auditor received their full balance information. Easy instructions can be provided. Auditors should be impartial, their identities and process public, and they should be rotated so that the same auditor is never used twice in a row. Balancing the cost of auditing against the needs for regular updates, a 6 month cycle likely makes the most sense. Hot Wallet Management The best solution for hot wallets is not to use them. CoinBerry reportedly uses multi-sig on all withdrawals, and Bitmex is an international example known for their structure devoid of hot wallets. However, many platforms and customers desire fast withdrawal processes, and human validation has a cost of time and delay in this process. A model of self-insurance or separate funds for hot wallets may be used in these cases. Under this model, a platform still has 100% of their client balance in cold storage and holds additional funds in hot wallets for quick withdrawal. Thus, the risk of those hot wallets is 100% on exchange operators and not affecting the exchange users. Since most platforms typically only have 1%-5% in hot wallets at any given time, it shouldn't be unreasonable to build/maintain these additional reserves over time using exchange fees or additional investment. Larger withdrawals would still be handled at regular intervals from the cold storage. Hot wallet risks have historically posed a large risk and there is no established standard to guarantee secure hot wallets. When the government of South Korea dispatched security inspections to multiple exchanges, the results were still that 3 of them got hacked after the inspections. If standards develop such that an organization in the market is willing to insure the hot wallets, this could provide an acceptable alternative. Another option may be for multiple exchange operators to pool funds aside for a hot wallet insurance fund. Comprehensive coverage standards must be established and maintained for all hot wallet balances to make sure Canadians are adequately protected.
Current Draft Proposal
(1) Proper multi-signature cold wallet storage. (a) Each private key is the personal and legal responsibility of one person - the “signatory”. Signatories have special rights and responsibilities to protect user assets. Signatories are trained and certified through a course covering (1) past hacking and fraud cases, (2) proper and secure key generation, and (3) proper safekeeping of private keys. All private keys must be generated and stored 100% offline by the signatory. If even one private keys is ever breached or suspected to be breached, the wallet must be regenerated and all funds relocated to a new wallet. (b) All signatories must be separate background-checked individuals free of past criminal conviction. Canadians should have a right to know who holds their funds. All signing of transactions must take place with all signatories on Canadian soil or on the soil of a country with a solid legal system which agrees to uphold and support these rules (from an established white-list of countries which expands over time). (c) 3-5 independent signatures are required for any withdrawal. There must be 1-3 spare signatories, and a maximum of 7 total signatories. The following are all valid combinations: 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7. (d) A security audit should be conducted to validate the cold wallet is set up correctly and provide any additional pertinent information. The primary purpose is to ensure that all signatories are acting independently and using best practices for private key storage. A report summarizing all steps taken and who did the audit will be made public. Canadians must be able to validate the right measures are in place to protect their funds. (e) There is a simple approval process if signatories wish to visit any country outside Canada, with a potential whitelist of exempt countries. At most 2 signatories can be outside of aligned jurisdiction at any given time. All exchanges would be required to keep a compliant cold wallet for Canadian funds and have a Canadian office if they wish to serve Canadian customers. (2) Regular and transparent solvency audits. (a) An audit must be conducted at founding, after 3 months of operation, and at least once every 6 months to compare customer balances against all stored cryptocurrency and fiat balances. The auditor must be known, independent, and never the same twice in a row. (b) An audit report will be published featuring the steps conducted in a readable format. This should be made available to all Canadians on the exchange website and on a government website. The report must include what percentage of each customer asset is backed on the exchange, and how those funds are stored. (c) The auditor will independently produce a hash of each customer's identifying information and balance as they perform the audit. This will be made publicly available on the exchange and government website, along with simplified instructions that each customer can use to verify that their balance was included in the audit process. (d) The audit needs to include a proof of ownership for any cryptocurrency wallets included. A satoshi test (spending a small amount) or partially signed transaction both qualify. (e) Any platform without 100% reserves should be assessed on a regular basis by a government or industry watchdog. This entity should work to prevent any further drop, support any private investor to come in, or facilitate a merger so that 100% backing can be obtained as soon as possible. (3) Protections for hot wallets and transactions. (a) A standardized list of approved coins and procedures will be established to constitute valid cold storage wallets. Where a multi-sig process is not natively available, efforts will be undertaken to establish a suitable and stable smart contract standard. This list will be expanded and improved over time. Coins and procedures not on the list are considered hot wallets. (b) Hot wallets can be backed by additional funds in cold storage or an acceptable third-party insurance provider with a comprehensive coverage policy. (c) Exchanges are required to cover the full balance of all user funds as denominated in the same currency, or double the balance as denominated in bitcoin or CAD using an established trading rate. If the balance is ever insufficient due to market movements, the firm must rectify this within 24 hours by moving assets to cold storage or increasing insurance coverage. (d) Any large transactions (above a set threshold) from cold storage to any new wallet addresses (not previously transacted with) must be tested with a smaller transaction first. Deposits of cryptocurrency must be limited to prevent economic 51% attacks. Any issues are to be covered by the exchange. (e) Exchange platforms must provide suitable authentication for users, including making available approved forms of two-factor authentication. SMS-based authentication is not to be supported. Withdrawals must be blocked for 48 hours in the event of any account password change. Disputes on the negligence of exchanges should be governed by case law.
Continued review of existing OSC feedback is still underway. More feedback and opinions on the framework and ideas as presented here are extremely valuable. The above is a draft and not finalized. The process of further developing and bringing a suitable framework to protect Canadians will require the support of exchange operators, legal experts, and many others in the community. The costs of not doing such are tremendous. A large and convoluted framework, one based on flawed ideas or implementation, or one which fails to properly safeguard Canadians is not just extremely expensive and risky for all Canadians, severely limiting to the credibility and reputation of the industry, but an existential risk to many exchanges. The responsibility falls to all of us to provide our insight and make our opinions heard on this critical matter. Please take the time to give your thoughts.
It has been shared on multiple subreddits so I have no idea where to even post this. But I'd like to come up with a follow-up thread with some more information. The internet is the most powerful tool that mankind has ever invented. You have the ability to reach thousands, millions and even billions of people with just a computer and some internet access.
If you're on this subreddit, chances are you're already playing Tibia and you already have a computer and internet access. It doesn't need to be the best internet, but as long as websites will load (eventually) you are good to go.
In this topic I will go more in-depth on web development and software engineering. If you have a very slow internet connection, you may want to look into web development instead of software development. An application/software is much heavier (larger file size) than a website. And most developer jobs require that you send and download files, back and forth, between you and your company's server. So if you feel like your internet is too slow to send a lot of files - do not worry! There are plenty of jobs.
First, I will go through some more details on how to learn web development and software development. After that, I will list a few other kinds of jobs that you can do remotely. These types of jobs can be done from anywhere in the world as long as you have internet access.
Part 1: Some languages you should learn
What is web development? Well, it can be a lot of things. You perhaps make websites for shops/restaurants/hair dressers/dentists, or you work for a big company and work on their web application, like Outlook, Discord or Spotify (which can all be accessed via a browser: their web app). You can also work with design and user experience, instead of programming. Being a web developer can mean so many different things, it's impossible to name them all. But most web developers are just developers: they program. They make websites, and they either sell the websites to companies (as a consultant) or you work full/part-time for a company.
I can not provide in-depth information about every single thing, but I can give you some pointers. The very basics any web developer should know is this:
HTML (HyperText Markup Language) - it's what almost all websites use as a foundation. This is not a programming language, but it is a markup language. If you want to build websites, you pretty much have to know this language. Don't worry though, it is easy. Not so much to learn. You can learn all about it in a few weeks.
CSS (Cascading Style Sheets) - it's what will add colors and shapes to your website. If you want to focus more on design (also known as front end development) then this is where you want to gain a lot of knowledge.
Python - A very simple language to learn. This language is very often the first programming language that developers start using. You can use it for a lot of things. This language is used in the back of a lot of websites. Google has been using Python for years and still is. It's great for web scraping and making web requests. If you want a language to practice your algorithms, then this language is awesome.
PHP - This used to be a very popular language, but not so much these days. However, it is very good to know how this works because it's very simple to learn and also very functional in some cases. If you want to transmit or withdraw information from a database to your website, then this (in combination with SQL) is a great way to do so. Whenever you make a login system or a contact form, the data must be sent somehow to a recipient or a database. PHP will help you do that. It is a server-side language, which means it will run in the back of the website.
SQL - To be able to communicate with databases (for example: save data, update data, or insert data) you can use different languages for that. But SQL is probably the most widely used language for this. It is basically just a bunch of commands that you tell your website or app to do. If you have a web shop for example, you will need a database to store all your product information in. You can for example use MySQL as your database and then use the SQL language to extract data from your database and publish it as a list of products on your website.
Java - This is pretty much 90% identical to C# as I wrote above. Widely used, relatively easy to learn the basics and there's plenty of jobs. If you like making android apps, this language is for you.
Part 2: Technologies and useful tools
To become a web developer you will need a few tools. You need a text editor, a FTP client, a SSH client and some other things. Also a good browser.
Text editor: Visual Studio Code, Atom, Sublime Text, Brackets - There are many different text editors but at the moment, I highly recommend Visual Studio Code. It has so many built-in features it's honestly the only thing you may need.Don't forget to install Notepad++ as well - this very basic editor is so handy when you just quickly need to edit some files.
File archiving: WinRar, 7-Zip - You need some way of archiving projects and send it to your customer or employer. These are basic tools anyone should use. I personally use Winrar.
FTP (File Transfer Protocol): FileZilla - This tool will allow you to connect to your website's file manager and upload your files to it. There are many tools for connecting to an FTP server but this is the most popular one, it's simple and it works great.
VPS (Virtual Private Server): Amazon Web Services, Google Cloud - If you want to practice building web applications or want to host your own website as a fun project, it's great to use a VPS for that. Both Amazon and Google offers 365 days of free VPS usage. All you need is a credit card. However, they will not charge you, as long as you stay below the free tier limit. A VPS is basically a remote computer that you can connect to. I highly recommend that, if you have a slow internet connection. Those VPS-servers (by Amazon and Google) usually have 500mbit/s internet speed, which is faster than most countries in the world. You simply connect to them via Remote Desktop, or by SSH. Depending on what type of server you are using (Windows or Linux).
SSH (Secure Shell): Solar-PuTTY, PuTTY - If you for example have a web server where you store applications and files, a great way to connect to it is by using SSH. PuTTY is pretty much the standard when it comes to SSH clients. But I really love the version created by SolarWinds. When you download that one, do not enter your personal details. Their sales people will call you and haunt you! Haha.
File Searching: Agent Ransack - When you have many files and try to locate a specific document or file, you may want to use something like Agent Ransack. Much faster than the traditional search feature in Windows and it is much more accurate.
IDE / Code Editor: Visual Studio - Great tool to use when you want to create applications in C# for example. Do not confuse this with Visual Studio Code. These are two very different tools. This tool (Visual Studio) is more designed for Windows applications. Not just websites. I only recommend getting it if you plan to make programs for Windows.
Web host & domain: NameCheap, Epik, SiteGround - If you develop websites on your own, or maybe want to create a portfolio website, you will need a domain name and web hosting. I have personally used all of these 3 and they are very cheap. NameCheap has some of the cheapest domains and great web hosting for a low price. Their support is also great. Same with SiteGround. And if you want to buy a domain anonymously (with Bitcoin for example), then you can use Epik. Low prices and great customer service on all these 3 websites.
Web Browser: Mozilla Firefox, Microsoft Edge Insider, Google Chrome - You need one of the latest web browsers to create websites these days. Since I prefer privacy over functionality, I've always loved Firefox. But recently, Microsoft has been improving its new version of Edge a lot (based on Chromium) and it's also very popular. If you want all your personal details to be saved and have good tools for web development, then use Google Chrome. Don't forget to utilize the built-in developer tools. You can access it in any of these browsers by pressing F12.
Other things you may want to look into:
Web services, SSL certificates, Search Engine Optimization, Databases, API, Algorithms, Data Structures
If you want to learn in-depth about algorithms, data structures and more. Then you can take a look at the curriculum of the top-tier universities of USA. Such as: UC Berkeley, Harvard and MIT. These courses are very hard and are specifically for people who want to become experts in software engineering. You can enroll some of them for free, like the one on Harvard. And by having a such diploma (which costs $90 extra) can get you a lot of job opportunities. You can enroll those courses if you want, but it can have a fee. But just take a look at what they are studying and try do their exercises, that is 100% free. Get the knowledge. It's mostly on video too! These course below are the very same courses that many of the engineers at Facebook, Google, Amazon, Apple, Netflix, Uber, AirBnb, Twitter, LinkedIn, Microsoft, etc. has taken. It's what majority of people in Silicon Valley studied. And it's among the best classes that you can take. These course are held by some of the world's best professors in IT.
