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.

[IDEA] [PROPOSAL] Monero Debian (deb) packages / Debian package repository deb.getmonero.org (I can do)

I have the skills to implement this if wanted.
Possible User Experience
This is a proposal, i.e. not implemented yet. Instructions for users, simplified.
How to install monero using apt-get
Download the repository signing key.
wget https://www.getmonero.org/monero.asc
Add the signing key.
sudo apt-key --keyring /etc/apt/trusted.gpg.d/monero.gpg add ~/monero.asc
Add APT repository.
echo "deb https://deb.getmonero.org buster main" | sudo tee /etc/apt/sources.list.d/monero.list
Update your package lists.
sudo apt-get update
Install monero.
sudo apt-get install monero
A few technical implementation details
I would simply grab the binaries provided by getmonero.org, download them, check software (gpg) signatures, put these into deb packages, add these to a repository, and upload the repository.
What I would not do is creating the binaries during package creation. While this is nice to have, it doesn't help user experience and blocks the progress on reaching this goal. See next chapter.
Why simply put the pre-build Monero binaries into a deb package?
1) After bitcoin existing for more than 10 years, being popular and being in Debian unstable (sid) it still never made its way into Debian testing, let alone stable. Reason being explained that a difference in underlying libraries (even just security fixes) during compilation may result in a network split. Binaries compiled during packaging on different versions of Linux distributions might have different libraries that might cause a network fork / chain split.
References:
(Note: above website saying Tags: fixed-upstream is probably a mistake as discussion at bottom says.)
2) The github issue of packaging monero stalled.
3) By shipping the same binaries as provided by getmonero.org reduces the chances of introducing a backdoor.
Many Options
Timeline
Doable quickly. The electrum (bitcoin) AppImage was recently added to a Debian package (binaries-freedom) by me and is now easily installable in Whonix. Pre-installed in testers version of Whonix already.
About Me
I am the founder of Whonix, which I am maintaining at present for more than 7 years.
Whonix (formerly TorBOX) is a Debian GNU/Linux–based security-focused Linux distribution. It aims to provide privacy, security and anonymity on the internet.
You can see an overview of packages I am maintaining on my github profile.
To proof that this forum account adrelanos corresponds the same person maintaining whonix.org, it is added here.
Questions
What happened to, what is the successor of the forum funding system?

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

Short PSA:

The slock.it team are being quite secretive about the amount of funds they wish to obtain from theDAO to build the USN. In their draft proposal and on other forums they state they are waiting to see how much theDAO raises, and how much the community is willing to invest in them before they submit an 'asking amount'. This is morally wrong and not how a contracted business should act.
Do not simply go along with just any amount they request from theDAO
If the DAO and the USN are to have a long lasting mutually benefical relationship then two things need to happen.
If we allocate more funds than required to slock.it to build the USN there will be alot of "wastage" and therefore a need to make up for that wastage in higher USN fees to help theDAO make a return on its investment. This is bad for the USN and therefore bad for the DAO.
Just like any other business contracting a developer, that contracted party needs to provide in depth, detailed, objective estimates on the expected expenses required to perform the task, in advance of submitting an asking amount. This estimation needs to be inspected and signed off as legitimate and worthy before entering into a contract for work to be undertaken.
If slock.it ask for too much, the USN will suffer and the DAO will suffer, by way of high USN fees and reduced or non-existant return on investment for theDAO.
Shoving a fee structure into what should be an open source, free to use, community project is already extremely risky! The only way this will work is with fees so small they are almost irrelevant, and that is only possible if we expect small fees, and we will only expect small fees if our investment in building the USN was efficient and smart.
SOLUTION: ensure slock.it are not asking for more than reasonably required to complete the task of coding a sharing network on an easy-to-build-upon-platform (ethereum). And repackaging existing technology components loaded with ubuntu core to make a pretty box called the "ethereum computer" (this is NOT the same as 21.inc fabricating micro payment asic chips to be embedded in qualcomm devices). Plus a bit of "social media" marketing etc.
This amount should equal quite an INSIGNIFICANT percentage of the already raised $40+ million USD.
And quickly to this argument of incentives. No one will build and maintain a free to use USN without getting paid. Then I guess no one is building and maintaining bitcoin for free, or linux.. FYI There WILL be other open source community built sharing networks without a DAO taking fees.
Conclusion: Throwing money at slock.it will not help theDAO and the USN. It will hinder the USN's adoption by way of necessary higher fees to make back what we "theDAO" invested, and therefore hurt theDAO's ROI and long term prospects as an organisation / investment fund.
Do not let slock.it take an unnecessary amount of money for no reason. Any organisation (including DAO's) that want to be around and still growing in two years know this. Lets make theDAO no different. Think smart

Not one person ever had an issue with malware or a virus using the KORE wallets.
With this unexpected price rise, many are curious what KORE has to offer and what the coin is about.
KORE is a project centered around security in Communications, Computer, Smart Phone and Marketplace interaction and use. There are a few other KORE Projects we cant yet announce. Lets talk a bit on the ones we're able to disclose...
1-Integrated Tor for secure transactions and staking 2-Integrated Tor browser for secure web surfing 3-KOREPBX for secure wallet to wallet and Telecom number calling and video. 4-KOREbay A unique Tor hosted Marketplace 5-Aether Krypton OS - A new Operating System based on Security and Privacy 6-KOREPhone - Our KORE branded phone to debut the AEOS also centered on security and privacy with some unique features. 7-KORE PoBA - Our end goal of the holy grail of anonymous currencies.
KORE is the first coin to integrate Tor into the wallet transactions and staking meaning your IP is not seen. KORE had also been the first coin to integrate a PBX based wallet to wallet calling service. We are presently working on the end goals of including Video Calling, messaging and making it a bit more decentralized and secure with the end goal of having it run through the Tor network. We also want to include the ability to dial regular telecom numbers. This work is in progress and some is undergoing testing.
KORE also is the first coin to work on a multi year project of an Operating system centered around privacy and security called the Aether Krypton OS. https://finance.yahoo.com/news/korecoin-team-announces-korephone-smart-041800325.html
The Operating System is planned to debut on the KOREPhone, another first. https://forum.xda-developers.com/android/apps-games/ther-apps-coders-shout-ground-floor-t2956802
KORE with another first integrated a Tor Browser into the Linux wallet some time ago to debut in the new release. This allows you to surf the web in privacy and security.
KORE was also first to announce the unique KOREbay marketplace which is in development. This service will be unlike many other crypto related marketplaces and have additional hosting on the Tor Network.
Our goal is to take what we have and upgrade anonymous currencies to the next level.
For now these are the projects in various stages of development and testing that we can talk a little bit about. We will not give out any road maps. The releases could start in 2-5 months or 2-5 weeks. This is about giving the growing KORE community and Investors an idea of the perceived value of what we are bringing to the crypto/public as a means of providing alternatives to choose from. There are plenty more KORE Team projects and we could possibly post a few of those once the new wallet is released in the new OP page where dissemination of information will be a little more open. Join the KORE Revolution!
Yours Truly, MikeMike

$750 Quadruple Monitor Linux Rig

I'm using the same formatting here as suggested by the Tek Syndicate forums. Thanks for the help guys, it is much needed!
Intro
I don't know much about building computers, yet, so thanks for reading this. I need a computer that can push four monitors. I use Linux which complicates things. Choosing the graphics card seems to be the hardest part for me. I'd like to get a graphics card that is either supported on Linux by the manufacturer with proprietary drivers or one that is supported with open source drivers. Whichever is fine, I just want it to work. Eyefinity support would be great too, I have 3 1920x1200 monitors in portrait mode so I'd like to run them all as one display when I watch movies (this way I can watch 4K content).
Budget. How much are you willing to spend?
$750. Spending less would be nice. I will spend more than $750 if need be.
Where do you live (what country), and what currency do you use?
United States. I live in a big city so I also have plenty of physical stores near by (microcenter, best buy, etc.)
Is there a retailer you prefer?
Newegg/Amazon (I have free 2 day shipping on those sites). I will buy wherever is the cheapest though.
Do you need or already have peripherals? (this can add to costs)
I already have these items:
What will you be using your future computer for? Gaming? Rendering? Mix of both? Or is this a home media PC?
Web browsing, photoshop, watching video (not editing video), and programming. I don't game so I won't need as powerful of a computer. I really need something that can push all 4 monitors while Web browsing, photoshop, watching video, and programming at the same time.
Do you overclock or want to get into overclocking?
Overclocking isn't a priority for me. If the CPU and graphics cards can be overclocked then I will if cooling isn't a problem.
Do you plan on going for custom watercooling now, or in the future?
No.
OS. Do you need a new one?
No. I use Ubuntu, Debian, and Arch. I will also be installing Windows 7 Home Premium with a license key I have.
Do you plan on mining bitcoin?
Yes! If cooling isn't a problem I certainly will be mining bitcoin or litecoin.
Do you render movies or photshop pictures?
I edit photos with GIMP but I may move to Abode Photoshop. I don't edit much video.
If there are any parts that you must have, and you don't want to be swayed against, such as a particular graphics card cooler, or a certain SSD, case, etc., then please specify that.
I'd like to get a 128gb SSD. I don't need any additonal storage.
I'd like to get 8gb of FAST ddr3 ram.
3 of my monitors have displayport which helps for picking a graphics card!
I want the motherboard to have USB 3.0. Front or back ports is fine with me.
I'd like to get a Fractal Design case. Cheaper black minimal cases work for me as well.
I have these parts from an old desktop I scrapped if they are useful:

Optional Beginner Guide to Litecoin: TESTED 12/7/2013

Plan B: BAMT Live USB
This option is a last resort, hopefully not necessary. Download BAMT from the link below and "dd" via terminal to USB formatted to FAT32 in gparted. You can install gparted in xubuntu by typing:
sudo apt-get install gparted 
Next, launch gparted and format your USB drive. Be careful not to format your HDDs! You might double-check the storage sizes as a reference in the upper-right drop-down menu.
Download link: https://mega.co.nz/#!NI5W2QLT!dYt2UTZz0hrFoiMUAu0d01eSD4pjqXHT6U2UtnAAGJ4
Extract the file and locate "litecoinbamt1.1.img"
Put image on 2GB or greater USB formatted to FAT32 by opening terminal and running:
sudo dd if=/path/to/litecoinbamt1.1.img of=/dev/sdX (The "X" is the device name of your usb key. The one you will have seen in gparted, for example "sdb, or sdc, or sdd..." Try to get the right device on the first try. Use raw device *not* a partition.) sudo dd if=(you can drag and drop file into the terminal here to get the path) of=/dev/sdX 
CAN TAKE 15 MINUTES or more.
Perhaps try newer release of BAMT: https://mega.co.nz/#!qZ1TXRxD!Mcw8pkrP4SQE8D7bIfmZZEola01hxVFtbOBg6Cr3Zeo
sudo dd if=/path/to/litecoinbamt1.2.img of=/dev/sdX 
(source: http://www.bitcointrading.com/forum/linux-distros/bamt-version-0-5-easy-usb-based-mining-linux-with-farm-wide-management-tools/)
Plan A: Xubuntu BFGminer
Step 1: Get prepared. This is for a FRESH install of Xubuntu 13.10. Start with a fresh installation. Run the following in the terminal, line by line, one at a time. Press enter after each.
sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev sudo aticonfig --lsa sudo aticonfig --adapter=all --initial sudo reboot 
(source: http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-linux/)
sudo apt-get install libcurl4-openssl-dev pkg-config libtool libncurses5-dev libudev-dev screen xterm sudo apt-get install git-core sudo apt-get install openssh-server byobu sudo apt-get install autoconf sudo apt-get install automake 
(source: https://coinaxis.com/index.php/entry/how-to-configure-linux-and-build-cgminer-for-bitcoin-and-litecoin)
sudo add-apt-repository ppa:unit3/bfgminer sudo apt-get update sudo apt-get install bfgminer sudo apt-get upgrade 
To launch:
bfgminer --scrypt -o stratum+tcp://world.wemineltc.com:3334 -u workername -p password -I 13
