Bitcoin Armory Keeps Crashing - Etf Sparplan Anleitung

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:

If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

INTRODUCTION

According to wikipedia, Blockchain is originally known as bloc chain, It is a growing list of records known as blocks which is linked using cryptography, each of these blocks contain a cryptographic hash of the initial block, a transaction data and a time stamp.
Since its emergence in the year 2008, when Nakamoto satoshi discovered and introduced bitcoin, there has been serious efforts to integrate the blockchain technology into several aspects of various process of global business , The blockchain technology has been described as having the potential to disrupt many industries with immutability, low-cost transaction, and enhanced maximum security. So many other blockchain implementations have been deployed and developed with unique features designed to specific use-cases.
The blockchain technology has made possible to issue assets through a distributed ledger framework. With cryptocurrency tokens, Assets can be given economic value in order to validate and initiate transactional processes.

ADVANTAGES OF BLOCKCHAIN:

  1. Decentralised payment processing,
  2. Creating an immutable system of recording,
  3. Reducing Cost of Transaction and
  4. Enhanced Security.
  5. Now that we have reminded ourselves of what blockchain technology is, let’s look into the subject matter.

ABOUT WolfpackBOT

WolfpackBOT is a highly advanced cryptocurrency trading software that allows for the execution of trades at lightning speed using proprietary trading algorithms, proprietary “Werewolf” Trading Analysis configurations, or user customized settings based on personal trading style. WolfpackBOT also allows for simultaneous trading access to all compatible cryptocurrency exchanges that are available to the bot, and all trading pairs with the WerewolfBOT subscription package.
WolfpackBOT is introducing an industry first, a beautiful automated cryptocurrency trading console: The WolfBOX. This efficient and sleek piece of hardware will conveniently allow for the full utilization of a bot subscription without the need for a VPS or dedicated computer. The WolfBOX will also include a built-in secure Hardware Wallet and RFID card reader to optimize ease-of-use and functionality.
WolfpackBOT trading software is enabled with limit, market, and “Wolf Trade” orders on all trading candles, including one-minute candles, with the widest array of technical trading indicators available on the market. WolfpackBOT's proprietary “Wolf Trade” orders provide superior market sell orders with a bite! WolfpackBOT is the only trading bot to feature live price scanning on your positions and also handles partial fills with ease, meaning you don’t miss out on orders. WolfpackBOT is incredibly fast and can fulfill up to 10,000 trades per day depending on market conditions and subscription package.
WolfpackBOT allows simultaneous trading access to all cryptocurrency exchanges that are available to the bot, and all trading pairs through the WerewolfBOT subscription plan. Not only do inferior bots allow limited access to one exchange and one trading pair per bot, they also store your API keys remotely on servers which are potentially susceptible to hacks and pump and dump attacks. User security and API key protection holds a high priority within the WolfpackBOT framework which is why it is the only trading bot that gives users full control with local management of their API keys.
Masternode and Proof of Work X11 Blockchain
Wolfcoin Blockchain with X11 Proof of Work Mining and Masternode Reward Systems The Wolfcoin blockchain and network are both designed and engineered to ensure store of value, transactional speed and security, and fungibility. The main goal of the Wolfcoin blockchain is to facilitate fast and secure transactions with a governance that helps sustain the network for the benefit of all users. The Wolfcoin blockchain is a two-tier network comprised of a Proof of Work (PoW) consensus mechanism powered by miners and a Proof of Service (PoSe) system powered by masternodes.
The Wolfcoin blockchain is secured through Proof of Work (PoW) in which miners attempt to solve difficult problems with specialized computers. When a problem is solved, the miner receives the right to add a new block to the blockchain. If the problem was solved correctly, the miner is rewarded once the block is added.
The second tier, which is powered by masternodes, enables Wolfcoin to facilitate private and instant transactions with Private Send and Instant Send. Masternodes are also rewarded when miners discover new blocks.
The block reward is distributed with 80% going to the masternodes and 20% going to miners. The masternode system is referred to as Proof of Service (PoSe), since the masternodes provide crucial services that support the features of the network.
Masternodes also oversee the network and have the power to reject improperly formed blocks from miners. If a miner tried to take the entire block reward for themselves, the masternode network would orphan the block ensuring that it would not be added to the blockchain.
In short, miners power the first tier, which is the basic sending and receiving of funds and prevention of double spending. Masternodes power the second tier, which provide the added features that make Wolfcoin different from other cryptocurrencies. Masternodes do not mine, and mining computers cannot serve as masternodes.
Additionally, each masternode is “secured” by 10,000 WOLF. Those WOLF remain under the sole control of their owner at all times. The funds are not locked in any way; however, if enough of the funds are moved or spent to cause the user’s holdings to drop below 10,000 Wolfcoin, the associated masternode will go offline and stop receiving rewards.
By pre-ordering your WolfpackBOT subscription, you will also receive Wolfcoin as a reward that can be utilized in the following ways:
  • Redeemable for WolfpackBOT subscriptions
  • Redeemable for the WolfBOX Console
  • Redeemable for WolfpackBOT and Wolfcoin apparel and merchandise
  • Fungible utility that can be exchanged for like value on exchanges
When you hold at least 10,000 Wolfcoin in your Wolfcoin wallet connected to a static IP address, you will become a masternode, meaning you will have a chance to receive 80 percent of the block reward every sixty seconds.

INTRODUCTION

Cryptocurrency is essentially digital money traded from one person to another through the use of pseudonyms. There are no intermediaries like banks, no governmental oversight or authority, and no fees. The “crypto” in cryptocurrency refers to the use of cryptography to ensure the security and privacy of every transaction.
New coins are created through a technique called mining. The process requires powerful computers that solve complex math problems. Each problem should take about 10 minutes to solve, and results in the creation of a predetermined number of coins. The total number of coins that can be created is fixed — there’s a limit of 21 million bitcoins that can be created. The number of coins rewarded for solving each problem dwindles as time goes on.
Bitcoin is believed to have been created in 2009 by Satoshi Nakamoto, an enigmatic figure who has so far proven all but impossible to definitively identify. By using cryptography to control the creation and tracking of a digital currency, Nakamoto took that power away from central authorities like governments.
Bitcoin was the first and most famous digital currency, but you can choose from more than 1,500, including ether, litecoin and even cryptokitties. For awhile, you saw these currencies only in the darkest corners of the internet, where people used them for all sorts of questionable, even illegal, activities. Drug dealers liked them because they made transactions all but invisible, and trolls at the Kremlin-backed Internet Research Agency used bitcoin to finance their campaign to influence the 2016 election.
That started to change in 2014, when Overstock became the first major US retailer to accept bitcoin. Companies like Expedia and Microsoft followed suit.
One of the biggest misconceptions about cryptocurrencies is that you need thousands of dollars to invest. It’s an easy assumption to make, especially in the case of bitcoin, which stayed under $1,000 from about 2010 to 2017. But then it took off, surpassing thousand-dollar milestones at a pace that seemed quicker than you could refresh your phone.
The staggering value is off-putting to many. But unlike most stocks, you can buy a fraction of a bitcoin so you don’t need thousands to get into the crypto game.

OVERVIEW OF WolfpackBOT

WolfpackBOT is a highly advanced cryptocurrency trading software that allows for the execution of trades at lightning speed using proprietary trading algorithms, proprietary “Werewolf” Trading Analysis configurations, or user customized settings based on personal trading style.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

Integrated into Blockchain Financial

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

Backup Wallet.dat

"1) I can backup my wallet by exporting a wallet.dat file. Do I have to do this everytime I receive more BBP? Or just whenever I add a new key? 2) How do I add new keys? 3) Can I generate and see the private key so that I can write it down/print it and store it somewhere safe?" -znffal
1) think of your wallet.dat file as your passbook in a passbook savings account. You have to have that .dat file to be able to access (and prove you SHOULD have access) to the BBP stored in your account addresses. Exporting it once is all you need.
2) Adding new keys? The passphrase (password) you use is the only "key" you would have in an encrypted wallet (besides the .dat file). If you mean new addresses, you can get those by going under File and Sending (or Receving) Addresses and hit "new".
3) Clicking Encrypt Wallet will be where you choose a passphase, I don't know you can see it other than when you enter it.
To put a real world example or two.
Example One: You don't ever encrypt or backup your wallet. If I borrowed/stole/hacked your computer, I could send all your coins to my wallet (no passphrase).
Example Two: You encrypt your wallet with the passphrase "secret" but don't backup the wallet.dat file, then your computer crashes and you lose all your data. Since you didn't have a copy of the wallet.dat file, your coins would be lost.
Example Three: You backup your wallet.dat but don't encrypt it. Your computer crashes and all your data is lost, but you re-download the QT program, restore your wallet.dat, all your coins are still in you wallet. But if you lose your USB drive that has the wallet.dat on it, and I find it, I can put your wallet.dat on another computer and send all your coins to my wallet.
Example Four: You encrypt your wallet and back up the wallet.dat file. If I hack/borrow your computer, unless I guess your passphrase your coins are safe. If you computer crashes, your can restore your wallet.dat file to another computer and your coins are safe.
In short, Encrypt your wallet (passpharse) and then backup (copy) the wallet.dat file to at least two locations." -616westwarmoth
"Find your wallet.dat file, copy it to a flash drive or any other secure place. If your computer crashes, you'll always have the wallet.dat and can put it on a new machine. It will have to resync a bit when you do, but you'll never lose your "key" to the wallet. Speaking of keys, you should password protect your wallet and make sure to remember it!"
"Yes you must have a copy of the wallet.dat somewhere. So multiple back up copies are a good idea. If you lose the wallet.dat file the coins will be in limbo but there will be no way to recreate the file. One thing to remember is it doesn't matter if the wallet.dat file is "current", it can be 10 years old on a flash drive and you can download a new client, put the wallet.dat file into the machine and you'll be good." -616westwarmoth
"In addition to this, whenever you reboot the node after more than 24 hours of being synced, we back your wallet.dat up into the "backups" folder. This is useful if you ever accidentally delete your wallet.dat.
Also, if you want a paper backup, you can do a 'dumpprivkey accountaddress' command from the RPC." -Rob
"wallet is a collection of private keys"
"there are other ways to achieve high security. You can make a new wallet, encrypt it with a long password, send coins to it, put it on a flash drive and put it in cold storage, then download the hard drive cleaning program and erase the wallet.dat sectors from your PC. And of course, keep a printed copy of the private key on paper and put it in a safe. Put the usb in the safe also. Burn a cd rom with the wallet.dat file and put it in the safe." -Rob

But when you click to generate a new address on the "Receive" tab, one key will be deducted from the keypool. Also, sometimes new addresses are automatically generated and the keypool is consumed, for example when solo mining and finding a block, a new address could be used for the block reward.
You can always check your current keypool size by typing "getwalletinfo" in the RPC console and see "keypoolsize" and "keys_left". It's only concerning if they are a low number and you plan to generate new addresses in your wallet. They start from 1000. If the number gets too low, you can just type "keypoolrefill" to refill them back to 1000 and then you should backup the wallet. But from my experience the wallet automatically refills the keypool from time to time (or after certain actions like transactions), because I see that my wallet file keeps getting larger and the "keys_left" returns to 1000.
The only issue is if you actively use your wallet on multiple computers (for example cloud mining or simply sometimes using the wallet on your laptop), then one wallet could refill the keypool with new addresses and the other one will not, or they will generate different new addresses. If I understand this correctly, for example, you could receive a payment on a new address generated in one wallet; your old balance will be there on both wallets, but only the one wallet where you generated the new address would show the new payment. Then you should copy the wallet.dat file to other computers, to update them.
If you use the wallet on just one computer, you should just backup the wallet from time to time (or when you see it has increased in size). Qt also backups wallet.dat automatically, those can be found in the folder %AppData%\BiblepayCore\backups, you will see that they also have timestamps in their names and possibly different sizes." -inblue

Compatibility

Microsoft ended support for Windows XP on April 8th, 2014,
an OS initially released in 2001. This means that not even critical security
updates will be released anymore. Without security updates, using a bitcoin
wallet on a XP machine is irresponsible at least.
In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
randomly crashing on Windows XP. It is not clear
what the source of these crashes is, but it is likely that upstream
libraries such as Qt are no longer being tested on XP.
We do not have time nor resources to provide support for an OS that is
end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
suggested to upgrade to a newer version of Windows, or install an alternative OS
that is supported.
No attempt is made to prevent installing or running the software on Windows XP,
you can still do so at your own risk, but do not expect it to work: do not
report issues about Windows XP to the issue tracker.
but severe issues with the libc++ version on 10.7.x keep it from running reliably.
0.13.1 now requires 10.8+, and will communicate that to 10.7 users, rather than crashing unexpectedly.
Notable changes

Segregated witness soft fork
Segregated witness (segwit) is a soft fork that, if activated, will
allow transaction-producing software to separate (segregate) transaction
signatures (witnesses) from the part of the data in a transaction that is
covered by the txid. This provides several immediate benefits:
Activation for the segwit soft fork is being managed using BIP9
versionbits. Segwit's version bit is bit 1, and nodes will begin
tracking which blocks signal support for segwit at the beginning of the
first retarget period after segwit's start date of 15 November 2016. If
95% of blocks within a 2,016-block retarget period (about two weeks)
signal support for segwit, the soft fork will be locked in. After
another 2,016 blocks, segwit will activate.

Open Bitcoin Privacy Protect Privacy Questionnaire, Mid-Year 2015 report | wei at openbitcoinprivacyproject.org | Aug 07 2015

wei at openbitcoinprivacyproject.org on Aug 07 2015:
Hi,
Hope it is OK to post this on the list, was not sure where else to post
for answers from Bitcoin-Qt client developers.
As part of the Open Bitcoin Privacy Project’s ongoing wallet privacy
measurement efforts, we’ve selected the Bitcoin-Qt client v0.11.0 for
inclusion into our 2015 mid year survey.
While our volunteers will be performing a series of functional tests by
interacting with your application directly, several of the features we’d
like to examine are not easily discernible by non-developers, and for
this reason we’re asking for your help.
If you can answer the following questions about your wallet’s behavior
it will assist us with the process of accurately rating your wallet’s
privacy features.
Transaction Formatting 
  1. Does your application take any steps to create ambiguity between
transactions which unavoidably spend from multiple addresses at the same
time and intentional mixing transactions?
  1. What algorithms does your application use for ordering inputs and
outputs in a transaction? In particular, how do you handle the change
output and do you take into account common practices of other wallet
applications when determining ordering?
  1. Does your application minimize the harmful effects of address reuse
by spending every spendable input (“sweeping”) from an address when a
transaction is created?
  1. Does your application fully implement BIP 62?
Mixing
  1. If your application supports mixing:
a. What is the average number of participants a user can expect to
interact with on a typical join transaction?
b. Does your application attempt to construct join transactions in a way
that avoids distinguishing them from non-join transactions?
c. Does your application perform any kind of reversibility analysis on
join transactions prior to presenting them to the user for confirmation?
d. Is the mixing technique employed secure against correlation attacks
by the facilitator, such as a CoinJoin server or off-chain mixing
service?
e. Is the mixing technique employed secure against theft of funds by the
facilitator or its participants?
Donations
  1. If your application has a fee or donation to the developers feature:
a. What steps do you take to make the donations indistinguishable from
regular spend in terms of output sizes and destination addresses?
Balance Queries and Tx Broadcasting
  1. Please describe how your application obtains balance information in
terms of how queries from the user’s device can reveal a connection
between the addresses in their wallet.
a. Does the application keep a complete copy of the blockchain locally
(full node)?
b. Does the user’s device provide a filter which matches some fraction
of the blockchain while providing a false positive rate (bloom or prefix
filters)?
i. If so, approximately what fraction of the blockchain does the filter
match in a default configuration (0% - 100%)?
c. Does the user’s device query all of their addresses at the same time?
d. Does the user’s device query addresses individually in a manner that
does not allow the query responder to correlate queries for different
addresses?
e. Can users opt to obtain their balance information via Tor (or
equivalent means)?
  1. Does the applications route outgoing transactions independently from
the manner in which it obtains balance information? Can users opt to
have their transactions submitted to the Bitcoin network via Tor (or an
equivalent means) independently of how they obtain their balance
information?
  1. If your application supports multiple identities/wallets, does each
one connect to the network as if it were completely independent from the
other?
a. Does the application ever request balance information for addresses
belonging to multiple identities in the same network query?
b. Are outgoing transactions from multiple identities routed
independently of each other to the Bitcoin network?
c. When an identity/wallet is deleted, does the deletion process
eliminate all evidence from the user's device that the wallet was
previously installed?
Network Privacy 
  1. When a user performs a backup operation for their wallet, does this
generate any automatic network activity, such as a web query or email?
  1. Does your application perform any lookup external to the user’s
device related to identifying transaction senders or recipients?
  1. Does you application connect to known endpoints which would be
visible to an ISP, such as your domain?
  1. If your application connects directly to nodes in the Bitcoin P2P
network, does it either use an unremarkable user agent string (Bitcoin
Core. BitcoinJ, etc), or randomize its user agent on each connection?
Physical Access 
  1. Does the application uninstall process for your application
eliminate all evidence from the user's device that the application was
previously installed? Does it also eliminate wallet data?
  1. Does your application use techniques such as steganography to store
persistent wallet metadata in a form not identifiable as belong to a
Bitcoin wallet application?
  1. Please describe the degree to which users can use passwords/PINs to
protect their data:
a. Can the user set a password/PIN to protect their private keys?
b. Can the user set a password/PIN to protect their public keys and
balance information?
c. Can the user set a password/PIN to encrypt other wallet metadata,
such as address books and transaction notes?
d. Does the application use a single password/PIN to cover all protected
data, or does it allow the use of multiple passwords/PINs?
Custodianship
  1. Do you as a wallet provider ever have access to unencrypted copies
of the user’s private keys, public keys, or any other wallet metadata
which may be used to associate a user with their transactions or
balances?
Telemetry Data 
  1. If your application reports telemetry data, such as usage
information or automatic crash reporting, does the user have the
opportunity to review and approve all information transmitted before it
is sent?
Source Code and Building 
  1. Can a user of your application compile the application themselves in
a manner that produces a binary version identical to the version you
distribute (deterministic build system)?
Thank you for assisting us with this effort to measure privacy progress
in the Bitcoin wallet space. If at all possible, please return this
survey before 2015/08/13 to ensure the score for your application will
be as accurate as possible.
Sincerely,
Wei

Bitcoin Core 0.10.0 released | Wladimir | Feb 16 2015

Wladimir on Feb 16 2015:
Bitcoin Core version 0.10.0 is now available from:
https://bitcoin.org/bin/0.10.0/
This is a new major version release, bringing both new features and
bug fixes.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues
The whole distribution is also available as torrent:
https://bitcoin.org/bin/0.10.0/bitcoin-0.10.0.torrent
magnet:?xt=urn:btih:170c61fe09dafecfbb97cb4dccd32173383f4e68&dn;=0.10.0&tr;=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&tr;=udp%3A%2F%2Ftracker.publicbt.com%3A80%2Fannounce&tr;=udp%3A%2F%2Ftracker.ccc.de%3A80%2Fannounce&tr;=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr;=udp%3A%2F%2Fopen.demonii.com%3A1337&ws;=https%3A%2F%2Fbitcoin.org%2Fbin%2F
Upgrading and downgrading

How to Upgrade
If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
bitcoind/bitcoin-qt (on Linux).
Downgrading warning
Because release 0.10.0 makes use of headers-first synchronization and parallel
block download (see further), the block files and databases are not
backwards-compatible with older versions of Bitcoin Core or other software:
  • Blocks will be stored on disk out of order (in the order they are
received, really), which makes it incompatible with some tools or
other programs. Reindexing using earlier versions will also not work
anymore as a result of this.
  • The block index database will now hold headers for which no block is
stored on disk, which earlier versions won't support.
If you want to be able to downgrade smoothly, make a backup of your entire data
directory. Without this your node will need start syncing (or importing from
bootstrap.dat) anew afterwards. It is possible that the data from a completely
synchronised 0.10 node may be usable in older versions as-is, but this is not
supported and may break as soon as the older version attempts to reindex.
This does not affect wallet forward or backward compatibility.
Notable changes

Faster synchronization
Bitcoin Core now uses 'headers-first synchronization'. This means that we first
ask peers for block headers (a total of 27 megabytes, as of December 2014) and
validate those. In a second stage, when the headers have been discovered, we
download the blocks. However, as we already know about the whole chain in
advance, the blocks can be downloaded in parallel from all available peers.
In practice, this means a much faster and more robust synchronization. On
recent hardware with a decent network link, it can be as little as 3 hours
for an initial full synchronization. You may notice a slower progress in the
very first few minutes, when headers are still being fetched and verified, but
it should gain speed afterwards.
A few RPCs were added/updated as a result of this:
  • getblockchaininfo now returns the number of validated headers in addition to
the number of validated blocks.
  • getpeerinfo lists both the number of blocks and headers we know we have in
common with each peer. While synchronizing, the heights of the blocks that we
have requested from peers (but haven't received yet) are also listed as
'inflight'.
  • A new RPC getchaintips lists all known branches of the block chain,
including those we only have headers for.
Transaction fee changes
This release automatically estimates how high a transaction fee (or how
high a priority) transactions require to be confirmed quickly. The default
settings will create transactions that confirm quickly; see the new
'txconfirmtarget' setting to control the tradeoff between fees and
confirmation times. Fees are added by default unless the 'sendfreetransactions'
setting is enabled.
Prior releases used hard-coded fees (and priorities), and would
sometimes create transactions that took a very long time to confirm.
Statistics used to estimate fees and priorities are saved in the
data directory in the fee_estimates.dat file just before
program shutdown, and are read in at startup.
New command line options for transaction fee changes:
  • -txconfirmtarget=n : create transactions that have enough fees (or priority)
so they are likely to begin confirmation within n blocks (default: 1). This setting
is over-ridden by the -paytxfee option.
  • -sendfreetransactions : Send transactions as zero-fee transactions if possible
(default: 0)
New RPC commands for fee estimation:
  • estimatefee nblocks : Returns approximate fee-per-1,000-bytes needed for
a transaction to begin confirmation within nblocks. Returns -1 if not enough
transactions have been observed to compute a good estimate.
  • estimatepriority nblocks : Returns approximate priority needed for
a zero-fee transaction to begin confirmation within nblocks. Returns -1 if not
enough free transactions have been observed to compute a good
estimate.
RPC access control changes
Subnet matching for the purpose of access control is now done
by matching the binary network address, instead of with string wildcard matching.
For the user this means that -rpcallowip takes a subnet specification, which can be
  • a single IP address (e.g. 1.2.3.4 or fe80::0012:3456:789a:bcde)
  • a network/CIDR (e.g. 1.2.3.0/24 or fe80::0000/64)
  • a network/netmask (e.g. 1.2.3.4/255.255.255.0 or fe80::0012:3456:789a:bcde/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff)
An arbitrary number of -rpcallow arguments can be given. An incoming connection will be accepted if its origin address
matches one of them.
For example:
| 0.9.x and before | 0.10.x |
|--------------------------------------------|---------------------------------------|
| -rpcallowip=192.168.1.1 | -rpcallowip=192.168.1.1 (unchanged) |
| -rpcallowip=192.168.1.* | -rpcallowip=192.168.1.0/24 |
| -rpcallowip=192.168.* | -rpcallowip=192.168.0.0/16 |
| -rpcallowip=* (dangerous!) | -rpcallowip=::/0 (still dangerous!) |
Using wildcards will result in the rule being rejected with the following error in debug.log:
 Error: Invalid -rpcallowip subnet specification: *. Valid are a single IP (e.g. 1.2.3.4), a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). 
REST interface
A new HTTP API is exposed when running with the -rest flag, which allows
unauthenticated access to public node data.
It is served on the same port as RPC, but does not need a password, and uses
plain HTTP instead of JSON-RPC.
Assuming a local RPC server running on port 8332, it is possible to request:
In every case, EXT can be bin (for raw binary data), hex (for hex-encoded
binary) or json.
For more details, see the doc/REST-interface.md document in the repository.
RPC Server "Warm-Up" Mode
The RPC server is started earlier now, before most of the expensive
intialisations like loading the block index. It is available now almost
immediately after starting the process. However, until all initialisations
are done, it always returns an immediate error with code -28 to all calls.
This new behaviour can be useful for clients to know that a server is already
started and will be available soon (for instance, so that they do not
have to start it themselves).
Improved signing security
For 0.10 the security of signing against unusual attacks has been
improved by making the signatures constant time and deterministic.
This change is a result of switching signing to use libsecp256k1
instead of OpenSSL. Libsecp256k1 is a cryptographic library
optimized for the curve Bitcoin uses which was created by Bitcoin
Core developer Pieter Wuille.
There exist attacks[1] against most ECC implementations where an
attacker on shared virtual machine hardware could extract a private
key if they could cause a target to sign using the same key hundreds
of times. While using shared hosts and reusing keys are inadvisable
for other reasons, it's a better practice to avoid the exposure.
OpenSSL has code in their source repository for derandomization
and reduction in timing leaks that we've eagerly wanted to use for a
long time, but this functionality has still not made its
way into a released version of OpenSSL. Libsecp256k1 achieves
significantly stronger protection: As far as we're aware this is
the only deployed implementation of constant time signing for
the curve Bitcoin uses and we have reason to believe that
libsecp256k1 is better tested and more thoroughly reviewed
than the implementation in OpenSSL.
[1] https://eprint.iacr.org/2014/161.pdf
Watch-only wallet support
The wallet can now track transactions to and from wallets for which you know
all addresses (or scripts), even without the private keys.
This can be used to track payments without needing the private keys online on a
possibly vulnerable system. In addition, it can help for (manual) construction
of multisig transactions where you are only one of the signers.
One new RPC, importaddress, is added which functions similarly to
importprivkey, but instead takes an address or script (in hexadecimal) as
argument. After using it, outputs credited to this address or script are
considered to be received, and transactions consuming these outputs will be
considered to be sent.
The following RPCs have optional support for watch-only:
getbalance, listreceivedbyaddress, listreceivedbyaccount,
listtransactions, listaccounts, listsinceblock, gettransaction. See the
RPC documentation for those methods for more information.
Compared to using getrawtransaction, this mechanism does not require
-txindex, scales better, integrates better with the wallet, and is compatible
with future block chain pruning functionality. It does mean that all relevant
addresses need to added to the wallet before the payment, though.
Consensus library
Starting from 0.10.0, the Bitcoin Core distribution includes a consensus library.
The purpose of this library is to make the verification functionality that is
critical to Bitcoin's consensus available to other applications, e.g. to language
bindings such as [python-bitcoinlib](https://pypi.python.org/pypi/python-bitcoinlib) or
alternative node implementations.
This library is called libbitcoinconsensus.so (or, .dll for Windows).
Its interface is defined in the C header [bitcoinconsensus.h](https://github.com/bitcoin/bitcoin/blob/0.10/src/script/bitcoinconsensus.h).
In its initial version the API includes two functions:
  • bitcoinconsensus_verify_script verifies a script. It returns whether the indicated input of the provided serialized transaction
correctly spends the passed scriptPubKey under additional constraints indicated by flags
  • bitcoinconsensus_version returns the API version, currently at an experimental 0
The functionality is planned to be extended to e.g. UTXO management in upcoming releases, but the interface
for existing methods should remain stable.
Standard script rules relaxed for P2SH addresses
The IsStandard() rules have been almost completely removed for P2SH
redemption scripts, allowing applications to make use of any valid
script type, such as "n-of-m OR y", hash-locked oracle addresses, etc.
While the Bitcoin protocol has always supported these types of script,
actually using them on mainnet has been previously inconvenient as
standard Bitcoin Core nodes wouldn't relay them to miners, nor would
most miners include them in blocks they mined.
bitcoin-tx
It has been observed that many of the RPC functions offered by bitcoind are
"pure functions", and operate independently of the bitcoind wallet. This
included many of the RPC "raw transaction" API functions, such as
createrawtransaction.
bitcoin-tx is a newly introduced command line utility designed to enable easy
manipulation of bitcoin transactions. A summary of its operation may be
obtained via "bitcoin-tx --help" Transactions may be created or signed in a
manner similar to the RPC raw tx API. Transactions may be updated, deleting
inputs or outputs, or appending new inputs and outputs. Custom scripts may be
easily composed using a simple text notation, borrowed from the bitcoin test
suite.
This tool may be used for experimenting with new transaction types, signing
multi-party transactions, and many other uses. Long term, the goal is to
deprecate and remove "pure function" RPC API calls, as those do not require a
server round-trip to execute.
Other utilities "bitcoin-key" and "bitcoin-script" have been proposed, making
key and script operations easily accessible via command line.
Mining and relay policy enhancements
Bitcoin Core's block templates are now for version 3 blocks only, and any mining
software relying on its getblocktemplate must be updated in parallel to use
libblkmaker either version 0.4.2 or any version from 0.5.1 onward.
If you are solo mining, this will affect you the moment you upgrade Bitcoin
Core, which must be done prior to BIP66 achieving its 951/1001 status.
If you are mining with the stratum mining protocol: this does not affect you.
If you are mining with the getblocktemplate protocol to a pool: this will affect
you at the pool operator's discretion, which must be no later than BIP66
achieving its 951/1001 status.
The prioritisetransaction RPC method has been added to enable miners to
manipulate the priority of transactions on an individual basis.
Bitcoin Core now supports BIP 22 long polling, so mining software can be
notified immediately of new templates rather than having to poll periodically.
Support for BIP 23 block proposals is now available in Bitcoin Core's
getblocktemplate method. This enables miners to check the basic validity of
their next block before expending work on it, reducing risks of accidental
hardforks or mining invalid blocks.
Two new options to control mining policy:
  • -datacarrier=0/1 : Relay and mine "data carrier" (OP_RETURN) transactions
if this is 1.
  • -datacarriersize=n : Maximum size, in bytes, we consider acceptable for
"data carrier" outputs.
The relay policy has changed to more properly implement the desired behavior of not
relaying free (or very low fee) transactions unless they have a priority above the
AllowFreeThreshold(), in which case they are relayed subject to the rate limiter.
BIP 66: strict DER encoding for signatures
Bitcoin Core 0.10 implements BIP 66, which introduces block version 3, and a new
consensus rule, which prohibits non-DER signatures. Such transactions have been
non-standard since Bitcoin v0.8.0 (released in February 2013), but were
technically still permitted inside blocks.
This change breaks the dependency on OpenSSL's signature parsing, and is
required if implementations would want to remove all of OpenSSL from the
consensus code.
The same miner-voting mechanism as in BIP 34 is used: when 751 out of a
sequence of 1001 blocks have version number 3 or higher, the new consensus
rule becomes active for those blocks. When 951 out of a sequence of 1001
blocks have version number 3 or higher, it becomes mandatory for all blocks.
Backward compatibility with current mining software is NOT provided, thus miners
should read the first paragraph of "Mining and relay policy enhancements" above.
