How To Send Bitcoins From A Paper Wallet | 99 Bitcoins

Importing Private keys into a QT based wallet, how is it done?

Before the fork I had been storing my tokens in MultiBit. I saw no need to incur a transaction fee to transfer those tokens into a QT compatible wallet format prior to the fork. So now I am here with multiple files that contain the private key(s) from those wallets.
I now need to import these keys into both my Bitcoin (Cash) and Bitcoin (Settlement) QT clients. What are the steps necessary to accomplish this?
I did find https://bitcointalk.org/index.php?topic=336404.0
Is this a safe method in which to perform the activity? I will be importing to Bitcoin ABC v0.14.6 & Bitcoin Unlimited v1.0.3.0
  1. Export private key from MultiBit without password (Done)
  2. edit file with some editor like Notepad++ (I'll probably just use Notepad, unless that is a bad idea?)
  3. copy only key - this is row without # ,and you must copy only key - no date and another symbols , (row indicates that it might be better to import to a spreadsheet?)
  4. then in BitCoin-Qt open from Help->Debug window ->Console (I am able to navigate to where the Console is not located)
  5. importprivkey [label] [rescan=true]
(Where is the information I copied from step 3? and also without the '<>')
(where label is name of owner - your name.; is this necessary? Do I need to provide a label? Can I leave it blank? And if I can leave it blank would I simply omit that the '[label]' argument?)
  1. And when press enter the your address with coins will appear in your addresses and in your balance.
Additionally, can this activity take place on a computer that is not connected to the applicable network? I am still waiting (1 year 40 weeks behind) for the Bitcoin (Settlement) wallet to download the chain (for some reason copying over of the pre-fork blocks did not take and now that the fork has occurred I do not want to try to start over or run the risk of re-installing).
Thank you for your assistance.

How to get balances for address associated with Private Key bitcoinq/rpc

Hello,
I've been testing some things out with nodejs and bitcoin. I have a question, how do all these blockchain explorers show the balance for addresses that they dont own?
My end goal is to show the balance for addresses that are mine, I have the associated private keys and the addresses because i generated using bitcoinjs-lib.

I can use: importprivkey but I'm not entirely sure what is next aftewards.
Anybody have the exact commands i need to do in order to get the balances of addresses i own.

Thanks,

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.

How to Upgrade?

Windows
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.
OSX
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), run the dmg and drag Groestlcoin Core to Applications.

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).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

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.

Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

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

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

https://www.youtube.com/watch?v=Snr5e8bzftI
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.

If you held BCH on Jan 9th, you can now sell the fork "Bitcoin Candy" and get more BCH

On Jan 9th, bitcoin candy was credited to all users on coinex at a ratio of 1000 CDY for each BCH. It wasn't until a month later that the blockchain was live. And another couple weeks after that for coinex to open deposits and withdrawals. That day is today.
Right now the only way to claim your CDY is to run a full node and import the private key from your BCH wallet. Sorry that means it's impossible for hardware wallet users to claim at this time.
Here are the steps to claim your CDY:
  1. Download the CDY full node wallet for windows. If you don't have windows, run a virtual machine. It will take a few days to sync. https://github.com/bitcoincandyofficial/bitcoincandy/releases
  2. Send your BCH to a different wallet as you will be exporting your private keys. Do not export your private keys while you still have BCH in your wallet.
  3. In the CDY full node wallet, open the debug window and go to your console. Enter in the following command: importprivkey yourPrivateKey
  4. Wait for the node to fully sync and then your CDY should appear. You can now do whatever you want with it. I would recommend selling on coinex. You can get roughly 1 BCH for every 50 BCH you initially held in your wallet before the fork. Price is likely to trend down from now on.

Importing wallet in Bitcoin Core 0.17

I'm trying to import an old private, generated offline with an online wallet generator into Bitcoin Core 0.17.
I ckecked in some forums and it might be about the HD wallets. But I just generate a new wallet, I go to the console, I input "importprivkey "privkey" and at the end if I used dumpprivkey "publickey" I recive the message

Private key for address "" is not known (code -4)

Import old wallet/garlium addresses into new Garlicoin-Qt

I've noticed a few comments on the stickied posts with people wanting to import their keys/wallet data from Garlium. There seems to be a lack of information regarding this, but Garlicoin Core functions fundamentally the same way newer versions of Bitcoin and Litecoin core do - so the same commands can be used.
If using a vanity address/already removed private key, you can skip to step 4
Step 1: Open Garlium
Step 2: Go to file>Wallet>Private Keys>Export
Step 3: Garlium will now list your private keys (the second, longer string on each line) next to the corresponding public key (the shorter one you are probably used to seeing). Keep this open.
Step 4: Open Garlicoin core
Step 5: Go to Help>Debug Window>Console
Step 6: Type "importprivkey" followed by a space and the private key that you want to import into the console bar at the bottom. (can be copied from the previously opened garlium window)
Step 7: Repeat step 6 until all of your wanted keys have been imported. It is important to do each key individually.
Note: you may receive a "null" response from your console when doing this. As far as I can tell, this merely indicates that there is no data to import based on the current block your Garlicoin Core has caught up to. All this means is your transactions happened after that block/date and will not show until Garlicoin Core catches up. Once up to date, your Garlicoin Core wallet should function normally and show all previous transactions.
WARNING: Do NOT share your private keys with anyone. Anybody who has access to your private keys has access to your funds. Do not use any other commands in the garlicoin core console that you do not understand, as they can be used to trick you into giving others your precious garlicoin.

Are BCH txn still valid on BSV / How to get BSV out of pre-fork BCH address ?

I'd like to sell my BSV for BCH. Will the following work? I realize there is likely an easier way, but since my real funds are in Trezor, I have to work with rawtransaction. Trezor has its own version of createrawtransaction that I won't get into, I'm just curious if BCH TXNs are still valid on the BSV chain, and for how long?
  1. Find BCH addresses that are pre-fork
  2. Retrieve and secure the private keys for these addresses.
  3. Install Linux VM called "SV".
  4. Build bitcoin-sv from source and sync blockchain.
  5. Copy the wallet's current address (this will be our future target address).
  6. Copy the wallet's private key just in case anything goes horribly wrong.
  7. Install (2nd) Linux VM called "ABC"
  8. Build bitcoin-abc from source.
  9. Use importprivkey to import the pre-fork addresses into your fresh bitcoin-abc wallet.
  10. Use importprivkey to import your bitcoin-sv target addresses in case anything goes horribly wrong.
  11. Sync / rescan bitcoin-abc blockchain.
  12. Use createrawtransaction to get the TXN hex to spend the pre-fork BSV coins.
  13. Switch back to "SV" VM and use sendrawtransaction to put the TXN hex on the SV blockchain.
  14. Wait for confirmations on BSV block explorer to confirm BSV coins are claimed.
  15. Ensure you didn't leak any keys in 1-13 and sleep with one eye open.

Walk through of how to claim BCD Bitcoin Diamond

I am completely naive when it comes to Linux, coding, compiling, etc., so I found it difficult to follow advice I found for compiling the bitcoin diamond code form git. I followed a few guides for bitcoin core first and could never get it to work. I got some help from someone that knows Linux and here's what finally worked for me with BCD.
Use rufus to make bootable usb with ubuntu iso. (https://rufus.akeo.ie/)
Boot from the usb and install ubuntu.
Follow this guide to compile bitcoin from git: https://www.toshblocks.com/bitcoin/compile-bitcoin-source-code-ubuntu-16-04-lts/
Do the entire guide with bitcoin core to ensure everything is working.
Make sure you replace "theusername" with your own each time it appears, or make "theusername" your user name from the beginning.
There was one small difference, at the end of the guide to run bitcoin-qt it is ./src/qt/bitcoin-qt
At the end when trying to run bitcoin-qt (./src/bitcoin-qt) it said there was no such file, which made me think that I did something wrong but you just have to find where the file is. Hey, I said I was a complete noob, go easy on me.
When you repeat the procedure for BCD there will be a few small changes:
git clone https://github.com/bitcoin/bitcoin.git
becomes
git clone https://github.com/eveybcd/BitcoinDiamond.git
mkdir bitcoin/db4/
becomes
mkdir BitcoinDiamond/db4/
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/home/theusername/bitcoin/db4/
becomes
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/home/theusername/BitcoinDiamond/db4/
./configure LDFLAGS="-L/home/theusername/bitcoin/db4/lib/" CPPFLAGS="-I/home/theusername/bitcoin/db4/include/"
becomes
./configure LDFLAGS="-L/home/theusername/BitcoinDiamond/db4/lib/" CPPFLAGS="-I/home/theusername/BitcoinDiamond/db4/include/"
when you get to this line: [email protected]:~/BitcoinDiamond$ ./autogen.sh
I got the following error:
bash: ./autogen.sh: Permission denied
this command will show some information about autogen.sh
[email protected]:~/BitcoinDiamond$ ls -l autogen.sh

It should be good!
go to and run bitcoin-qt to start the gui
[email protected]:~/BitcoinDiamond/src$ cd qt
[email protected]:~/BitcoinDiamond/src/qt$ ./bitcoin-qt
bitcoin-wt will spend some hours syncing the entire blockchain so you have to wait.
When it is finished, import private keys by:
clicking in the "Bitcoin Core - Wallet" window to make it active
hover mouse in top left of the grey bar on the top of the deskto screen, not the "Bitcoin Core - Wallet" until it says "file settings help"
click on "help"
click on "Debug Window"
click on the "Console" tab
enter "importprivkey 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS" with your own key
make an account at gate.io where they are allowing deposits
sell!, or don't, maybe you're nuts, who am I to judge

For importprivkey, 0.9.2.1 just got a whole lot more inconvenient.

Up until today I'd been using 0.9.1, and sometimes using the console to import a few private keys. In that version, I could paste in multiple keys, hitting enter after each one (I think I pasted in 40 keys once). Since each key would take about 15 minutes to do each one, the whole client would basically lock up for key*15 minutes, which if I'm pasting in many, would be hours and hours.
This was fine with me however, because it would always come good at the end, and I could leave it alone, knowing that when it became responsive again, all 40 keys or whatever would have been imported.
Now, I've upgraded to 0.9.2.1 and I go to do the same thing, it pops up a little window saying 'rescanning' with a progress bar. Well, that's super nice and all for if you're importing only 1, but now I can't paste in a 2nd one, or a 3rd one, etc... I have to wait 15 minutes. So now importing 40 keys would be an absolute marathon of babysitting it every 15 minutes.
tldr The new "Rescanning" progress bar in 0.9.2.1 prevents me from pasting in multiple private keys into the console at once. I'm reverting back to 0.9.1.
edit Apparently rescan = false is a thing, so I can do tons of keys with just one rescan (15 mins) anyway :S Thanks chairoverflow and murbul.

How to claim Bitcoin 2s with a Bitcoin private key

  1. Download and install the Bitcoin 2 Core wallet
  2. Once you have the private key of a Bitcoin address that has BTC2, launch the Bitcoin 2 Core wallet
  3. Click tools -> debug console
  4. Type: importprivkey (type here your private key) and then press enter. Without the parentheses.
  5. It will rescan and after some time the BTC2 will show in your wallet's balance if the BTC address contained any.

Trying to salvage some coins from 2013. Core (bitcoin-qt.exe v0.8.1-beta on Windows 8.1) is taking weeks to DL the blockchain as expected but keeps crashing now. Can I upgrade to a newer version without losing what I've gotten already (about 75% complete)?

Currently there are 134305 blocks remaining. When I start it up it works pretty smoothly for a while but then slows down. I leave it running while I'm gone but the last several days when I've come back it has crashed and gives me an I/O error, and I have to hit OK then start it back up. It does appear to be further along when I start it back up but not by a whole lot. So this has really slowed my progress. It's reindexed about 75% though, and so I don't want to start over from the beginning.
The drive it is on has ~400gb of free space so that's not the issue. I have 8gb of memory, and the task manager says bitcoin is taking up about 500mb, but it's using 60-85% of my cpu at a time.
If I download a newer version of core, I can just copy/paste the old wallet.dat file, right? But wouldn't it have to start downloading the entire blockchain again from the beginning? If so, is there any quicker method?
While typing this, it crashed twice. It only runs for about 10 minutes.
The version I have doesn't have any settings I can change. I read that there's a db size limit you can change in later versions that could help. This one does have a "debug window" with a command line console but I don't really know what to do with it. Here is a list of available commands:

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.

Groestlcoin Sentinel (Android & Blackberry) – Mainnet + Testnet

What is Sentinel?

Groestlcoin Sentinel is the easiest and fastest way to track/receive/watch payments in your offline Groestlcoin Wallets. Groestlcoin Sentinel is compatible with any standard Groestlcoin address, BIP44 XPUB (Extended Public Key) BIP49 YPUB and BIP84 ZPUB

THAT'S RIDICULOUS!!! YOU DON'T NEED TO RUN AN ELECTRONEUM SERVER TO USE THE CORE WALLET/NODE. AND THE QT CORE IS JUST AS SIMPLE AS ELECTRUM (I THINK EASIER) PLUS IT ALLOWS FOR SO MUCH MORE FLEXIBILITY SHOULD YOU WISH TO DELVE INTO THE ADVANCED FEATURES. THE ONLY CAVEAT IS THE TIME TO SYNC AND THE SPACE REQUIRED. BUT IF EVERYONE SAID "FUCK THAT I'M NOT WASTING 250GB AND RUNNING MY WALLET 24/7 TO GET/KEEP IT SYNCED, OR WAITING FOR IT TO RESYNC EVERY TIME I WANT TO SPEND" THEN BITCOIN WOULD HAVE NO DECENTRALIZATION LEFT (WHICH HONESTLY IF YOU LOOK AT THE DECREASE IN NODES RUNNING, YOU'D SEE THAT'S WHAT'S HAPPENING.) ACTUALLY BELIEVE IN BITCOIN? THEN PUT UP OR SHUT UP!
Just run the core node! A.K.A. the full wallet. You don't need to set up an electrum server. That would only be if you wanted to contribute to the electrum network by serving as a public server. But honestly, it's much better to run the core in terms of decentralization anyway.
It requires no technical know-how! Only a couple hundred gigs of hard drive space and a week of letting the blockchain sync (for an average PC that's a few years old). And you can "prune" the node after it finishes syncing so you'll only need ~10GB of space when all's said and done (although you must have at least 250GB free to properly sync). Just download the official qt for whatever flavor of bitcoin/altcoin you need and run the installer.
It's honestly just as easy as electrum- you just need to sync first before you can spend.
Importing the xpriv's from your old electrum wallet is easy...
  1. Open debug window (help>debug window)
  2. Click on the 'command line' tab.
  3. Type `importprivkey ' (no <>).
*To get your xpriv (AKA private keys, out of electrum, right mouse button on all your addresses with funds and select show private key. Do this for each private key, importing one by one and you're done. If the repetition is too much for you. Just send all your coins to a single address first.
*NOTE THAT YOU MAY ALSO CHOOSE TO SIMPLY GENERATE A NEW ADDRESS FROM THE GUI IN THE CORE NODE AND SEND YOUR COINS FROM ELECTRUM TO YOUR NEW NODE. YOU MAY DO THIS AS SOON AS YOU'RE DONE SETTING UP THE CLIENT- HOWEVER YOU WON'T SEE THE TRANSACTION COME THRU UNTIL YOUR NODE SYNCS SO DON'T BE WORRIED ABOUT THAT ASPECT *
It'll take 7 minutes to set up and then you will not only be running securely, able to use any address format you want (including the segwit P2SH keys everyone should use for BTC), your txns and IP aren't logged by a random server, and you're helping maintain a Distributed Blockchain.
Forward the default port 8333 in your router NAT mapping and make yourself connectable to actually make a difference.
You'll probably notice your transactions confirm a tad bit faster during times of congestion as well.
