Bitcoin-Qt version 0.7.0 released

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!

GETTING COINS

Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.

MINING

Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.

GPU MINING

These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.

Trading

Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:

Faucets

Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!

Begging

This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.

Tips

At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

Keep your Bitcoin Core UASF node up to date

Note to folks with a fake uacomment: that neither helps nor works. Upgrade to BIP148!
Those who want to use BIP148 have two main choices: UASF BIP148 and Bitcoin Knots. The first has bip148 enabled by default. The second follows a PR originally proposed to Bitcoin Core (and rejected) which adds bip148=0 (option, disabled by default) so it needs to be enabled in configuration file or at runtime.
Make a backup of your wallet.dat, just in case.

Bitcoin Core SegWit UASF BIP148

This is the "original" BIP148 version.
1) Get the source at https://github.com/UASF/bitcoin/releases.
Current release: v1.0 - https://github.com/UASF/bitcoin/releases/tag/v0.14.2-uasfsegwit1.0
As a reminder, your install options are as follows:
a) Binaries: Bitcoin Core v0.14.2-based UASF SegWit BIP148 can be downloaded here (decompress and then run desired binary (bitcoind for daemon/server, bitcoin-cli for the CLI, etc.) which you can find in bin subdirectory; there's also a PPA for Ubuntu users who prefer apt-get install).
b) Source: get the source at the URL at the top. Build as usual, following official Bitcoin Core instructions.
To install, stop and (if you want) remove existing Bitcoin Core. Then install and run Bitcoin SegWit UASF BIP148. Windows users who use installer (filenames that end with *setup-unsigned.exe) should first uninstall existing Bitcoin Core before they install this version.
How to verify binaries (signatures):
https://np.reddit.com/Bitcoin/comments/6c5zw3/howto_verify_the_signed_uasf_released_binaries/
You can also verify checksums by importing Luke's PGP key and ensuring checksums in SHA256SUMS.asc(example here) match those of the downloaded file(s).

Bitcoin Knots

This is Luke-Jr's Bitcoin release with many enhancements and a BIP148 option. You can find more at https://bitcoinknots.org.
Get it at bitcoinknots.org. Install procedure for binaries is the same as for UASF BIP148 binaries, but with one added step:
Windows users who use installer (filenames that end with *setup-unsigned.exe) need to first uninstall existing Bitcoin Core before they can install this version.
If you want to build from the source, refer to Bitcoin Knots documentation (because it has a number of different options compared to Bitcoin Core).
How to verify binaries (signatures): download and import Luke's PGP key, refresh PGP keys, then verify the signed checksums file corresponds to the checksum of the binary you downloaded for your system.

Updating installed binaries

If you're updating either UASF BIP148 or Knots binaries (which you downloaded as zip or tgz file and decompressed to your disk), stop Bitcoin, decompress newer binaries over old binaries, then start service again. You can also move old binaries and then deploy the latest binaries.

Reverting to Bitcoin Core

Before chain split

Prior to chain split (such as before Aug 1), you can "go back" by simply removing BIP148 or Knots and installing Bitcoin Core 0.14.2. You can't go back to an earlier release such as 0.12 (same behavior as with Bitcoin Core).
Starting with UASF BIP148 v1.0, however, there's less need to be concerned about going back to Bitcoin Core - as mentioned above, Bitcoin Core 0.14.2 behavior can be achieved by restarting UASF BIP148 v1.0 or Bitcoin Knots with bitp148=0.
Should you want to remove UASF BIP148-compatible and run Bitcoin Core 0.14.2, you can do this:
Then install Bitcoin Core 0.14.2.

In the case of a chain split

Please remember to pay special attention to wallet.dat if you use one. This section only deals with the change of the binary and blockchain rewind, and not coin splitting and wallet backups.
If chains splits on or after August 1st, you would have to rewind the blockchain in order to use a different Bitcoin release on another chain. Details will vary depending on the circumstances (for example, we can't know in advance which chains will exist.)
UASF BIP148 v1.0 (not older releases) makes it possible to set bip148=0 and restart which automatically rewinds the blockchain to be consistent with Core. If you wanted to change to Bitcoin Core, you could first restart UASF BIP148 or Knots with bip148=0 to rewind the blockchain, then uninstall the binaries and install Bitcoin Core.
If a chain split happens, check UASFGuide.com or this subreddit for specific details.

Be back in late July!

In the second half of July, check for updates on a weekly basis. There may be further updates or improvements.

Changelog

2017-07-12 - reminder to pay attention to wallet backup in case of changing the binaries or startup options after a chain split
2017-07-11 - download links updated for v1.0, added about auto-rewind in v1.0, other small edits
Edit: this post may be updated prior to August 1st.

12-23 11:03 - 'I'm attempting to return stolen bitcoin and warning soon to be victims' (self.Bitcoin) by /u/MrBeanCoin removed from /r/Bitcoin within 89-99min

'''
Hello!
My name is MrBeanCoin (Not a obvious throw away! Of course not!). I'm my professional life I am a Malware Analyst, Pen Tester, and Engineer. However when im not working my eyes have been glued to the BTC charts, kicking myself for spending my BTC back when times were rough. But enough about me, lets get to the point.
 
Since the rise in price and popularity of Crypto's, Malware Authors have been leaving Ransomware, Botnets, and Spam in droves to create very simple Bitcoin and Altcoin stealing Malware, in a attempt to make the most money quicker, and separate good people like yourself from your coins. Miners have also reached unbelievable heights (Surpassing even when BTC first came out), and they make sure not to use safe settings, and a lot have been causing hardware damage. The spike has been so large that this week, the GTX 1080 i have in my Cuckoo Server (Automated Malware Analysis Platform) burned out from the constant throttling up and down.
 
So obviously, with my job, i have been having to deal with these fuckers and their shitty coded applications a lot. Some go as far as ripping your wallets from your machine and uploading them to a C2 server, but the absolute most common way people are losing bitcoins by the THOUSANDS is by the most simplest application i have ever seen. It simply lays low on the machine, and when it detects a BTC Address on the clipboard, it replaces the address you copied, with the Malware Authors. I know, right? At first i thought it would never be effective. However, so many newcomers are coming on the scene, it is paying off big. Nearly every wallet i have seen had at least 1 Million USD in it or more..... From a damn copy and paste switch. The worst part is, most people's security protection will not help them here, because the application does not look Malicious! All it is, is 3 lines of code changing the clipboard. Whats wrong with that? Well in this case, everything is. Please Please be on the look out for these. They make me so angry.. Other common ones are applications that try to pass as a update to , Bitcoin Duplicators (Ya...), Bitcoin Accelerators (I get this one, Noobs aren't getting why the TX's are fucking around), Fake Miners (If no one has heard of it, DONT USE IT), and Fake Wallets. I can go into these later if people are interested.
 
Anyways, I was looking at a sample today, and noticed this was one of the braver ones that scoop up the whole Wallet.Dat (Or similar) file, and kick it off to their servers. It does this for nearly 25 popular clients, even one called Armory which i thought was ironic.
 
This sample is hitting people through fake ad's to update their miners when visiting Crypto Sites, and more commonly, through email they are somehow getting for many exchange users. The emails claim either that they found your wallet publicly online! And that you should verify right away that it is actually yours. Its conveniently named "Wallet.dat .exe" with the spaces allowing the exe to hide in some email clients. When downloading and running, of course, you are infected. Other emails include free books on Crypto Currency that have a surprise for you inside! And Insider Information that you could use on a up coming pump and dump!
 
I loaded it into a IDA on a VM, and noticed that it wasn't sending the wallets to a domain, but rather a IP, and not only that, but what looked like a residential ISP IP. I allowed it to send up my fake wallets so i could get the scheme of the HTTP POST, and then started investigating the server. The guy receives loads of wallets a day, but he also runs a small botnet, proxy server, and password unhashing service on the same server. What was weird is i didn't see any templates, control panels, or mail for a web hosting company, which i normally see right away. I was starting to think this guy was actually dumb enough to use some server sitting at his house for this shit.
 
On further investigation of the client code talking to the server, i noticed he had a exploitable vulnerability in the way he uploaded files to the server. This allowed me to send up a payload with my wallet that later became my backdoor and reverse shell into his server. He was running a older kernel, so i was able to also exploit my way to root, and at this point i had full control over the server.
 
After further investigation, it was clear that indeed he IS running this out of his house. I somehow got lucky and out of 350 proxy servers, i managed to hop on his main node. Which he is a idiot anyways for accepting connections from anything but his proxies on this machine, or even using a home machine! Don't worry, i will be handing the needed information over to the feds for this little prick.
 
Now to my main point. It's obvious i must stay anonymous in this whole ordeal because, even though this dude is a POS, some people still might not be okay with what i did. And i also would like to keep my job haha. But seeing as i had full access, and this guy was dealing with BTC, this was a first for me. Most take overs i have done before, never had the actual wallets on the server. I really want to warn the victims he has FRESH wallets for ( IT COULD BE YOU! ), and also attempt to recover some BTC in the criminals wallets back to some, most likely worried sick, people.
 
I'm posting this today not only for the hope that if someone did notice Malware stole their coins, they can contact me and see if we can verify it was him, BUT ALSO in hopes that maybe any of you here would have any ideas on how i could go about finding these people, and then verifying its actually their BTC? I really can't think of any sure fire way accepting hoping people contact me and can match up the exact Transaction ID, Date, and Amount that was stolen from them. Please let me know your ideas.
 
I also want to finish this with a small list of FRESH VICTIMS that will most likely be getting hit very soon if they do not make a different wallet ASAP. I have hindered his processing further, but this doesn't help for already uploaded wallets. If these machine names match yours, PLEASE MAKE A NEW WALLET RIGHT AWAY: (Format is _.dat )

[uncensored-r/Bitcoin] I'm attempting to return stolen bitcoin and warning soon to be victims

The following post by MrBeanCoin is being replicated because the post has been silently removed.
The original post can be found(in censored form) at this link:

The original post's content was as follows:
Hello!
My name is MrBeanCoin (Not a obvious throw away! Of course not!). I'm my professional life I am a Malware Analyst, Pen Tester, and Engineer. However when im not working my eyes have been glued to the BTC charts, kicking myself for spending my BTC back when times were rough. But enough about me, lets get to the point.
 
Since the rise in price and popularity of Crypto's, Malware Authors have been leaving Ransomware, Botnets, and Spam in droves to create very simple Bitcoin and Altcoin stealing Malware, in a attempt to make the most money quicker, and separate good people like yourself from your coins. Miners have also reached unbelievable heights (Surpassing even when BTC first came out), and they make sure not to use safe settings, and a lot have been causing hardware damage. The spike has been so large that this week, the GTX 1080 i have in my Cuckoo Server (Automated Malware Analysis Platform) burned out from the constant throttling up and down.
 
So obviously, with my job, i have been having to deal with these fuckers and their shitty coded applications a lot. Some go as far as ripping your wallets from your machine and uploading them to a C2 server, but the absolute most common way people are losing bitcoins by the THOUSANDS is by the most simplest application i have ever seen. It simply lays low on the machine, and when it detects a BTC Address on the clipboard, it replaces the address you copied, with the Malware Authors. I know, right? At first i thought it would never be effective. However, so many newcomers are coming on the scene, it is paying off big. Nearly every wallet i have seen had at least 1 Million USD in it or more..... From a damn copy and paste switch. The worst part is, most people's security protection will not help them here, because the application does not look Malicious! All it is, is 3 lines of code changing the clipboard. Whats wrong with that? Well in this case, everything is. Please Please be on the look out for these. They make me so angry.. Other common ones are applications that try to pass as a update to , Bitcoin Duplicators (Ya...), Bitcoin Accelerators (I get this one, Noobs aren't getting why the TX's are fucking around), Fake Miners (If no one has heard of it, DONT USE IT), and Fake Wallets. I can go into these later if people are interested.
 
Anyways, I was looking at a sample today, and noticed this was one of the braver ones that scoop up the whole Wallet.Dat (Or similar) file, and kick it off to their servers. It does this for nearly 25 popular clients, even one called Armory which i thought was ironic.
 
This sample is hitting people through fake ad's to update their miners when visiting Crypto Sites, and more commonly, through email they are somehow getting for many exchange users. The emails claim either that they found your wallet publicly online! And that you should verify right away that it is actually yours. Its conveniently named "Wallet.dat .exe" with the spaces allowing the exe to hide in some email clients. When downloading and running, of course, you are infected. Other emails include free books on Crypto Currency that have a surprise for you inside! And Insider Information that you could use on a up coming pump and dump!
 
I loaded it into a IDA on a VM, and noticed that it wasn't sending the wallets to a domain, but rather a IP, and not only that, but what looked like a residential ISP IP. I allowed it to send up my fake wallets so i could get the scheme of the HTTP POST, and then started investigating the server. The guy receives loads of wallets a day, but he also runs a small botnet, proxy server, and password unhashing service on the same server. What was weird is i didn't see any templates, control panels, or mail for a web hosting company, which i normally see right away. I was starting to think this guy was actually dumb enough to use some server sitting at his house for this shit.
 
On further investigation of the client code talking to the server, i noticed he had a exploitable vulnerability in the way he uploaded files to the server. This allowed me to send up a payload with my wallet that later became my backdoor and reverse shell into his server. He was running a older kernel, so i was able to also exploit my way to root, and at this point i had full control over the server.
 
After further investigation, it was clear that indeed he IS running this out of his house. I somehow got lucky and out of 350 proxy servers, i managed to hop on his main node. Which he is a idiot anyways for accepting connections from anything but his proxies on this machine, or even using a home machine! Don't worry, i will be handing the needed information over to the feds for this little prick.
 
Now to my main point. It's obvious i must stay anonymous in this whole ordeal because, even though this dude is a POS, some people still might not be okay with what i did. And i also would like to keep my job haha. But seeing as i had full access, and this guy was dealing with BTC, this was a first for me. Most take overs i have done before, never had the actual wallets on the server. I really want to warn the victims he has FRESH wallets for ( IT COULD BE YOU! ), and also attempt to recover some BTC in the criminals wallets back to some, most likely worried sick, people.
 
I'm posting this today not only for the hope that if someone did notice Malware stole their coins, they can contact me and see if we can verify it was him, BUT ALSO in hopes that maybe any of you here would have any ideas on how i could go about finding these people, and then verifying its actually their BTC? I really can't think of any sure fire way accepting hoping people contact me and can match up the exact Transaction ID, Date, and Amount that was stolen from them. Please let me know your ideas.
 
I also want to finish this with a small list of FRESH VICTIMS that will most likely be getting hit very soon if they do not make a different wallet ASAP. I have hindered his processing further, but this doesn't help for already uploaded wallets. If these machine names match yours, PLEASE MAKE A NEW WALLET RIGHT AWAY: (Format is _.dat )

This is just a small list i could make tonight, i will hopefully be able to recover more and get more people switched to new wallets.
Thank you for your time.

Bitcoin-QT 0.9 disponível para download

The Core Developers of Bitcoin released the 0.9.0 FINAL of Bitcoin Core (aka Bitcoin QT).
DOWNLOAD:
This is a Final Version, but its the same as 0.9.0rc3
Sources: https://github.com/bitcoin/bitcoin/releases http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0/ https://bitcoin.org/bin/0.9.0/README.txt
Bitcoin Core version 0.9.0 is now available from:
https://bitcoin.org/bin/0.9.0/
This is a release candidate for a new major version. A major version brings both new features and bug fixes.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

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), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine.
On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.

Windows 64-bit installer

New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it.
NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.

OSX 10.5 / 32-bit no longer supported

0.9.0 drops support for older Macs. The minimum requirements are now: * A 64-bit-capable CPU (see http://support.apple.com/kb/ht3696); * Mac OS 10.6 or later (see https://support.apple.com/kb/ht1633).

Downgrading warnings

The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs).
Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem.
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).

Rebranding to Bitcoin Core

To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.

Autotools build system

For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles.
Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project.
Be sure to check doc/build-*.md for your platform before building from source.

Bitcoin-cli

Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.

walletpassphrase RPC

The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9.
The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays) 
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time) 

Transaction malleability-related fixes

This release contains a few fixes for transaction ID (TXID) malleability issues:

Transaction Fees

This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte.
Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions.
The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks.
The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.
