Groestlcoin 6th Anniversary Release


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?

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.
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.

Testnet Release


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.


Live Version (Not Recommended)



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! – Groestlcoin EasyVanity 2020

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).




Remastered! – Groestlcoin WPF Desktop Wallet (v2.19.0.18)

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode.
This wallet was previously deprecated but has been brought back to life with modern standards.


Remastered Improvements



ALL NEW! – BIP39 Key Tool

Groestlcoin BIP39 Key Tool is a GUI interface for generating Groestlcoin public and private keys. It is a standalone tool which can be used offline.



Linux :
 pip3 install -r requirements.txt python3 bip39\ 


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.

BTC Node. Need help with Ubuntu and BTC core program. To the Linux experts here in reddit.

The good thing of loosing a post, is that you have to retype everything and this means that you are able to shorten the post.
So. TLDR, I have 2 hdd, 80gb and 320, the second one has only, all the Blockchain info, from another already running node. I am not able to tell BTC Core program that the files are already there so he does not need to download 300gb. After hours of Google and linux forums, I am stuck in this issue. Every time I type "bitcoin-qt" on my terminal, it shows as a first download. Any help will be appreciate.

Full story.
English is not my first language, and this is being typed for second time (please have mercy on my grammar or misspelling mistakes), because I posted the question on linux subreddit nobody give a f..... so I decided to bring it here, posted a short post with the link and the automatic bot deleted because the of the link. I erased both the linux and the bitcoin post, and made a third one new, here, with plain text, copy pasting the info from the linux post. Never appeared on the "new" section of this sub. So hours of typing lost, and here we are.
Old Notebook. 80gb drive, and noob to Linux. Although I have some pc and logic knowledge, installed MINT due to a recommendation from a Bitcoin community, but since I have a friend with an already running node, with Ubuntu switched to this one, just to have the same system.
Once Ubuntu installed, on the 80gb and pc running, I copy and pasted the whole bitcoin folder from my friends pc to my 320 gb. Up to here all was good. But here is the problem

My friend, who does not understand nothing about linux, is owner of a company and has an IT guy who made everything for him, but would not be willing to help me a lot, (just to be good with his boss but right now it is not reachable for me), but when we where on my pc he told me that Linux is very sensitive to ports, in other words, a small usb change, will do a program to loose the path for the files. SO, instead of using the 320gb disk on USB i installed on this notebook second Hdd bay (its an old high end laptop with 2 sata connectors), he was able to set the program and everything went well for a couple of hours, Bitcoin Core program started synchronizing, downloading very little info.

I needed to turn of the pc to move it, so closed the program (waited until bitcoin core program told me was safe to) and turn it off, then turn it on again, and the problem was there, bitcoin core program started trying to download the whole blockchain in the spare 2gb of the 320 gb disk.
So what it seemed to happen is that even when the disk is installed on a sata bay from the motherboard, as I did not installed ubunutu with this disk connected it's route (adress?) is dinamyc and that is why BTC Core Program lost the files and does not recognize it.
After hours of google, linux forums and "askubuntu" i was able to, mount the 320gb disk, first editing the fstab ( i followed the guide in "") by the way. Trying to use VIM editor was a pain, it is REALLY difficult to type something there, and save it without pressing a wrong key. I had to cancel and start over at least a dozen times (plus reading several guides), but still was not able to mount the disk (Actually after following the steps, the hdd (320) disappeared from the GUI). went back, erased, and the did the NANO steps, and I THINK that now the hard drive it is fixed (before, any change,when restarting the second hdd took some time to appear, now it seems that is mounted and to a fixed adress). Well, after mounting the hdd, I tryed to call the bitcoin-qt and the initial download page appear and again tries to download from the initial block. I searched over hours "file association in ubuntu", "program files path" etc etc and the only thing I found is how to set up the desired software to open a file.

For you to understand my mess, when I did the "user:user" thing, I did not understand completely what I was doing, (yes I had to be in sudo) BUT i think I managed to did the correct thing as both hdd are shown in the Ubuntu GUI.

Some additional data is
Both hard drives are formated in Ext4
I have (I think that) a fstab.bak before any changes

I knwo that linux users sometimes ask for details on the system, just tell me the commands and i can run them to stick any info needed.

Thanks for the help in advance.

Reddcoin on Raspberry Pi

A lot of user asked lately, how to run Reddcoin on the popular Raspberry Pi platform. Raspberry Pi is a cheap ARM computer (using junk leftover chips with 10 year lag in technology) but it has enough RAM and consumes around 5 watts, so its ideal to use it for Reddcoin Staking.
This tutorial is not from me, i take NO RESPONSIBILITY about these binaries or the accuracy. This tutorial is created by cryptoBUZE, a fellow member of the Reddcoin community.
Before attempting to follow this tutorial, do a sudo apt-get update
The following commands must be run to install dependencies:
sudo apt-get install libboost-thread-dev
sudo apt-get install libboost-program-options-dev
sudo apt-get install libboost-filesystem-dev
sudo apt-get install libboost-system-dev
Download and install older libssl version - bitcoin clones are using this glorious and fantastic communist product of openssl so it naturally does not works. Its getting totally incompatible after each relase even with itself. Therefore, you must install this, which is the compatible one with the wallet software (no, you cant even compile the code with the newer one) :
sudo dpkg -i libssl1.0.0_1.0.1t-1+deb8u6_armhf.deb
sudo dpkg -i libssl-dev_1.0.1t-1+deb8u6_armhf.deb
Download the wallet software itself:
chmod +x reddcoin\*
When speaking about compatibility, ARM is similar to x86 if you are running user mode applications. You know that every arm based chip needs a different kernel due to the lack of an unified IO system thankfully for the glorious clueless egoistic communist developers at ARM, who succesfully bankrupted the corporation after 25 or so years, and the company got acquired by the japanese softbank. But in user mode, its sort of backward compatible if you have all the proper libraries installed. This means that this will run on any other newer ARM based machine as well (not just raspberry pi-s, on every other arm stuff, chromebooks, or android phones hacked to work with linux).

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


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.





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


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.

Run a 0.14 Full-Node on RaspberryPi3 Pruned(less than 16GB SD needed)

Happy if this guide helps you.
Tip if you want: 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v
UPDATE 04/06/17
Add 'uacomment=UASF-SegWit-BIP148' into your bitcoin.conf if you want to signal UASF.
UPDATE 03/13/17
ADDED a tl;dr; Version at the end of this Post.
UPDATE 03/12/17:
Just to test it - I reinstalled all on 8GB SD and it works as well. But maybe you should use at least 16GB for the beginning.
Using a 128GB card for the first version was a little bit stupid - so I reinstalled everything on a 8GB SD card. Including Linux and a pruned blockchain - and it works.
I used prune=550 and Jessie Lite (headless / command line) - without wallet and gui.
The SD is almost full, but it works so far
I also updated the whole manual a bit to make things more clear. Thank you for all your feedback!
Just started my Bitcoin Node today and wanted to share the way I did it with people who are interested in running their own full node. It took some time to write everything down - hopefully correct so far.
I am sure, many people around bitcoin are way more informed and educated as I am - I am the noob. So I wrote this manual to help users like me - noobs, to get started with a cheap, simple bitcoin node on raspberry pi.
Have fun!
I wanted to get my Raspberry Pi 3 working as a node to support the network. Actually the process of installing and running the node was more or less easy - but for Noobs (like I am) it might be a bit tricky to start the whole thing, because there are different ways.
Did you - like me - think you would need +120GB on the raspi, external USB HDD to be a full node? You won't!
If you have a Raspberry and you know what Bitcoin is, I guess, you are a little bit aware of linux, networks and of course bitcoin - so I won't go into detail too much.
This guide is just a little helper to get a full node running on your raspberry pi. Thanks to the help of the nice people in this sub and of course the documentation by the developers, I got it working - and of course also special thanks to - as I followed their tutorial to start - I went some other ways here and there - so please read carefully.
For the Part 2 I would suggest to have open and read through my manual.
I split the tutorial in 2 Parts - PART ONE is about installing the client on your PC and downloading the Blockchain.
PART TWO is about the setup of the raspberryPi and transferring the pruned blockchain to the pi and run it as a full node!
The first thing to be aware of is: You actually need to download the whole blockchain to get this working - if you already have your bitcoin client synced on the PC / MAC great you can reuse it!
Now you might think "but you said less than 16GB in the title!"
Yes, but the good thing is you won't need to download it on your Raspberry, neither you need to sync it completely on your raspberry which took ages (weeks!) before. When you finished this Guide, you will just have a max. 4GB Blockchain on your Raspberry Pi - but it still is a full node! The magic word is Pruning.
Maybe even a 8GB SD Card works just fine including Linux (jessie lite)!
So, if you already have a full node on your PC - Great you can almost skip PART ONE - BUT have at how to Prune in PART ONE if you don't know about it.
For PART TWO you'll need a Raspberry Pi 2 or 3 (I used 3) min. 8GB (works also) or better 16GB SD Card. (I used a 128GB for the first version of this manual - which is way too big)


This is the manual how to get started on you PC / MAC / Linux (I did it on Win7)
Go to: and download the core Client for your Machine (I used win64).
Install it and configure it to save the Blockchaindata to the directory of your choice - so instead getting 120GB on your C drive, I would suggest to download it to another place like a USB drive.
You can set this up during the install. Standard folder for the blockchain folder is "%APPDATA%\Bitcoin" on Windows.
or you can do it after the install by creating a bitcoin.conf file inside your installation folder / or %APPDATA%\Bitcoin and add
to the file. Line by line.
By the way here you could also just add dbcache - to use more memory to speed up the process a bit:
if you don't want to use the settings inside the program. (you can also set this inside the program under settings! If you have this inside the bitcoin.conf you will see the amount you set there from inside the program - it overrides the values)
You can check inside the windows client under settings, if you can see a manual dbcache is set by having a look at the left footer area. When your dbcache value shows up, everything is fine.
So the Blockchain download process will take time - maybe a few days! Depending on your machine, internet connection and HDD.
The Blockchain is huge as it contains every single transaction of the past until today. You won't need to keep your PC running all the time, you can turn it off and on and it will resync automatically when you start bitcoin-qt.exe!
Make sure to close the client always via "quit" - ctrl+q.
After you have your bitcoin core installed, the blockchain downloaded and synced - you are ready to PRUNE!
First - close the Client and let it close smoothly. After it is really closed you can follow these steps:
By pruning, your blockchain will dramatically shrink. From 120GB to just a few GB.
Be aware, that you will lose your Downloaded Blockchain as pruning will erase a big chunk of it! If you have enough space, you could of course keep the full blockchain saved somewhere on another HDD.
You can prune by editing your bitcoin.conf file by adding:
I used prune=1024 - not sure where the differences are right now (min. prune=550). (for my 8GB version I used 550! I suggest to use this.)
Save the bitcoind.conf file and restart your windows client.
It will now clean up the Blockchain. So just the latest blocks are saved. The client should start without any problems. Maybe it takes some time to prune the blockchain data.
Check if everything works normally (the client opens as usual, you can see an empty wallet) than close the client.
Inside the Bitcoin Folder, you'll find two folders called:
blocks chainstate
those are the interesting folders containing the important data (now pruned) - and we will transfer those two to the raspberry later!
Now you are good to start the raspi transfer explained in the next part.


Here is what I did:
1) I installed Raspian Pixel ( using a 128 GB SD - which is not needed because of "Pruning" - I think a 16GB card might work, too! (You can also install Raspian Jessie Lite - which saves you even more space, as it runs headless - only command line) (Updated: It is better to use Jessie Lite to save a lot of space - when you are fine with only command line)
2) I followed partly this tutorial to get everything running and setup:
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped.
Set You RasPi up including "EDITING FILES" to save your Layout at the tutorial page and come back here.
I skipped the CONFIGURE USB AND SET AUTOMOUNT process, as we are going to use PRUNING to reduce the 120GB to a tiny filesize - so USB Devices are not needed here!
It was necessary to ENLARGE SWAP FILE to install bitcoin core - otherwise it didn't went through which ended in a frozen raspi.
So have a close look by following the raspnode tutorial at: ENLARGE SWAP FILE.
I have my raspi running via cable to router - but you can also WiFi setup everything described under NETWORKING ON THE RASPBERRY PI.
Now comes the interesting part: Follow the steps at DOWNLOADING BITCOIN CORE DEPENDENCIES - they work fine for 0.14.0 too. Git should be on Board already when you installed Pixel - otherwise you would need to install it.
sudo apt-get install git -y (only jessy lite)
I skipped the next command lines - as I don't use bitcoin-qt wallet. If you want to use it as wallet - do the step.
mkdir ~/bin cd ~bin
Now you are in the folder you want your bitcoin core data be downloaded to via git. I didn't Downloaded the Berkeley Database source code - so I also skipped the whole next command lines
[email protected]~/bin$ wget [email protected]~/bin$ tar -xzvf db-4.8.30.NC.tar.gz [email protected]~/bin$ cd db-4.8.30.NC/build_unix/ [email protected]~/bin/db-4.8.30.NC/build_unix$ ../dist/configure --enable-cxx [email protected]~/bin/db-4.8.30.NC/build_unix$ make -j4
and went on with "INSTALLING BITCOIN"!
I followed the first part but instead downloading 0.13 I took of course the latest version:0.14
git clone -b 0.14 cd bitcoin ./
this might take some time to start.
If you have trouble with hanging RESOLVING DELTAS - just restart the Raspberry Pi and remove the bitcoin folder inside /~bin using
rm -rf bitcoin
this command will delete the folder and you can reuse
git clone -b 0.14

For some reason RESOLVING DELTAS is a common problem with different downloads - so just retry it and at least after 3 times it should work!

as I didn't use the GUI/ Wallet, I ran
./configure --enable-upnp-default --disable-wallet
as I don't need the wallet functionality.
I didn't need to use "MAKE" which saves you maybe up to 2.5 hours.
instead you can just go ahead with:
sudo make install
(If I am wrong in doing so - please let me know)
The install takes some time - and just a heads up: when it gets stuck somewhere - just redo the installation process - it took three times to went through - stuck at some processing.
After the installation took place you can finally get your Raspberry Pi Node running in no time!
To test if the the installation went through - you can just start bitcoind using:
bitcoind &
than check if everything is working so far:
bitcoin-cli getinfo
after a few seconds you should see version: etc...
if not, something went wrong. Try to redo the steps in the raspnode tutorial.
(don't give up if it failed - retry! Ask your questions here)
IMPORTANT: you need to stop bitcoin on your raspberry now!
bitcoin-cli stop
If you don't need an external USB Drive - what I hope - as we are going to use pruning just go ahead and skip the USB part and create a file inside (or follow the raspnode tutorial on how to setup the USB drive):
cd .bitcoin
sudo nano bitcoin.conf
and enter the exact same pruning size you have used on your Desktop Machine to prune. I used 1024 but the minimum is 550. (used 550 for the 8GB SD card on PC and Raspberry)
That's it for the raspi.
update: To signal UASF enter in a new line:


Now you have to transfer the two folders CHAINSTATE and BLOCKS from your PC bitcoind directory to your raspberry.
I am using a program called "WINSCP" - it is free and easy to use:
We need this to transfer the files to the Raspberry pi. Pretty sure you can also do it via SSH - but I am the noob. So let's keep it simple.
Open Winscp and put in the IP Address of your Raspberry Pi, User and Password (same as in SSH)
You should now see the directories on your Raspberry Pi. There is a folder called
enter it and you will see the two folders
blocks & chainstate
you can delete them on the raspberry as they have some data from your previous test inside.
Make sure you can also see the bitcoin.conf file in that directory, which needs to contain the exact same prune line, like the one on your desktop machine. If not, make sure to edit it via SSH. The line "datadir=l:\yourfolder" is obviously not needed in the Raspberry bitcoin.conf file.
Now grab the two folders CHAINSTATE and BLOCKS from your PC and copy them to your .bitcoind folder.
I also copied banlist.dat, fee_estimation.dat, mempool.dat and peers.dat to the folder - not really knowing if needed! Not needed.
The whole copy process might take some minutes (against some weeks in the old way).
After copying is finished, you can now start bitcoind on the Raspberry.
bitcoind &
the & symbol let you still use the command line while the process is running btw.
The process - if succesfull - will take some time to finish.
bitcoin-cli getinfo
Will give you some informations what is going on right now. When you can see, that it is checking the blocks, this is good!
If you get an error - double check - if you have the correct prune size (same as on desktop machine) - in bitcoin.conf and that this file is inside .bitcoin on RaspberryPi. It took me some time, to find my mistakes.
Congrats! You are almost a part of the network!
To make your node now a fullnode, you will need to go to your router (often and enable portforwarding for your raspberry pi - and open ports 8333 - that's it!
You can now go to:
scroll down to "JOIN THE NETWORK" and check check if your node IP is connected!
It will show up as soon as the blocks are checked and the raspi is running.
Well done!
Now you are running a full node, with a small Blockchain and got it working in Minutes, not weeks!
I really hope, my little tutorial worked for you and your are part of the Node network now.
If you have problems or I made a mistake in this helper tut, just let me know and I will try to make it better.
Have fun and NODL!
the noob
tl;dr; (if you are a real noob start with the non-tl;dr version!)
tl;dr; PART ONE
1) Download & install / setup bitcoincore @
2) change dbcache to something smaller than your memory and download the whole Blockchain (120GB).
3) create a file called bitcoin.conf put the line prune=550 (or higher) in to activate pruning on win inside %appData%/bitcoin
4) Open ports 8333 on your Router to make this a full node with a smaller Blockchain.
You are running a full node on your PC.
tl;dr; PART TWO
1) Install jessie lite and the needed dependencies on your SDCard - Raspberry
( >git clone -b 0.14 )
  • see tutorial for more info.
2) create a file called bitcoin.conf inside .bitcoin and add the same prune=Number you had on your PC.
3) transfer the pruned folders BLOCKS and CHAINSTATE to the Raspberry Folder .bitcoin
4)Start "bitcoind &"
5) let everything sync
6) Make sure you have port 8333 opened on your router.
You are running a full node on your Raspberry with a super small Blockchain (I put all on a 8GB SDcard)

Homelab collective ressources post!

Hey guys!
I'm fairly new to this sub and to having a home lab in general and I found this community to be so kind and helping, I wanted to give back what I've learned. I'm seeing a lot of questions asked around on improvements and on what to do with x extra hardware so I thought it would be nice to have a thread to regroup that.
I'll put here some stuff I gathered and the most common questions I've seen, feel free to contribute and i'll update the post along.

How to Mine BiblePay on Linux

This guide is outdated, please refer to:
IMPORTANT - Evolution Upgrade:
Quick Start
Evolution Upgrade Information
Getting Started with Evolution
Generic Smart Contracts
What is BiblePay Evolution?
Recommend 2GB RAM or can get stuck compiling (if 1GB RAM can use Swap File) Use Ubuntu 16.04
apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler apt-get install git apt-get install curl build-essential libtool autotools-dev automake pkg-config python3 bsdmainutils cmake sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install libdb4.8-dev libdb4.8++-dev git clone prefix=x86_64-pc-linux-gnu cd biblepay-evolution/depends make -j4 # Choose a good -j value, depending on the number of CPU cores available cd .. ./ #Note: if echo `pwd` does not return your working directory, replace it with your working directory such as /biblepay-evolution/ ./configure --prefix `pwd`/depends/x86_64-pc-linux-gnu make # See more here: # 

NOTE: if server is 1GB RAM, before running last command "sudo make", set up a swap file
free #check if swap is 0 dd if=/dev/zero of=/vaswap.img bs=1024k count=1000 mkswap /vaswap.img swapon /vaswap.img free #check if swap is 1024 sudo make 

cd src ./biblepayd -daemon 
Your GUI program will be located in: /biblepay-evolution/src/qt
You can also run it in the background (to free up your terminal) if you call it with:
./biblepay-qt & 
To start mining, instructions are the same as for Windows: Go to Tools -> Debug Console
Execute this command (to start mining with 8 threads)
setgenerate true 8 
From there you can use all other commands such as getmininginfo, getwalletinfo, etc. Execute help command to get the list of all available commands.
Note: GUI will be built automatically only if you meet the requirements for qt library, i.e. make sure you ran this line before compiling:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler 
BIBLEPAY is now Running!

Stop BiblePay and set up the config file to get starting nodes to sync with and enable mining:
./biblepay-cli stop cd ~/.biblepayevolution/ vi biblepay.conf gen=1 genproclimit=1 
Escape Key + : (Colon Key) + w + q + Enter (saves file and quits)

addnode --- adds a node to the list of nodes to connect to gen=1 --- turns on mining genproclimit --- sets number of threads to use when mining

Run BiblePay again and fully sync with network
cd ../biblepay-evolution/src ./biblepayd -daemon ./biblepay-cli getinfo 

./biblepay-cli help ./biblepay-cli getaccountaddress "" ./biblepay-cli getinfo ./biblepay-cli getmininginfo ./biblepay-cli setgenerate true 8 ./biblepay-cli sendtoaddress "insertAddressHere" 777 "" "" true ./biblepay-cli stop ./biblepayd -daemon top #CPU usage q to quit 

MINING THREADS: To change number of threads to use up for mining
a. Edit home/yourusername/.biblepayevolution/biblepay.conf file:
and restart BiblePay -or- b. Menu >> Tools >> Debug Console >> Type command:
setgenerate true X 
(Replace X with number of threads Use top command to view CPU usage)

NOTE: To use the pool you must now use the external miner, not the wallet miner
  1. Set up an account on pool website:
  2. Create Worker Username(s) - Workers tab >>> Add
  3. Enable pool and add Worker Username in ~/.biblepayevolution/biblepay.conf file, add these lines and save:
    pool= workerid=insertWorkerUsernameHere
4. Restart BiblePay
./biblepay-cli stop ./biblepayd -daemon 
Setup Auto-Withdraw Navigate to Account >>> Account Settings >>> Verify your BBP Receiving Address >>> Click Authorize-Auto-Withdraws


### Turn off/stop BiblePay
cd /home/yourname/biblepay-evolution/src ./biblepay-cli stop 

### Pull down latest Biblepay code and build it
cd /home/yourname/biblepay-evolution git pull origin master sudo make 

### Turn BiblePay back on and check version number
cd src ./biblepayd -daemon ./biblepay-cli getinfo ./biblepay-cli setgenerate true 8 

./biblepay-evolution/src/biblepay-cli stop ; cd && cd biblepay-evolution/ && git pull origin master && sudo make && cd src && ./biblepayd -daemon && sleep 90 && ./biblepay-cli getmininginfo 
Note: the ";" says do this after, regardless of the outcome Note: && says do this after only if previous command finished with no errors

To speed up the compile time, add -j4 or -j8 after make. This way it compiles using 4 or 8 threads instead of just 1.
./configure LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/" sudo make -j8 

RSYNC stop biblepay from your nodes compile on your fastest machine then rsync with your machines only src folder is required
rsync -avuz /root/biblepay-evolution/src/ [email protected]:/root/biblepay-evolution/src/
people make cron jobs and rsync automatically

Interested in contributing to the BTC network? Here is the steps to get a full node up and running in Linux.

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info:
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > > gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page ( The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

The Strange Birth & History of Monero, Part IV: Monero "as it is now"

You can read here part III.
You can read this whole story translated into Spanish here
This is part IV, the last but not least.
Monero - A secure, private, untreceable cryptocurrency
Notable comments in this thread:
-201: “I would like to offer 1000 MRO to the first person who creates a pool”
[tacotime offers bounty to potential pool developer. Bytecoin devs haven’t released any code for pools, and the only existent pool, minergate (in the future related to BCN interests) was closed source]
-256: “Adam back seems to like CryptoNote the better than Zerocash”
-264: “update on pools: The NOMP guy (zone117x) is looking to fork his open source software and get a pool going, so one should hopefully be up soon.”
-273: “Update on GUI: othe from VertCoin has notified me that he is working on it.”
-356: “Everyone wanting a pool, please help raise a bounty with me here:
And for the GUI:”
[5439 MRO + 0.685 BTC + 5728555.555 BCN raised for pool and 1652 XMR, 121345.46695471 BCN for the GUI wallet. Though this wallet was "rejected" as official GUI because wallet still has to be polished before building a GUI]
-437: “Yes, most Windows users should see a higher hashrate with the new build. You can thank NoodleDoodle. ”
-446: “Even faster Windows binaries have just been uploaded. Install for more hash power! Once again, it was NoodleDoodle.”
-448: “that almost doubled my hashrate again! GREAT STUFF !!!”
-461: “Noodle only started optimization today so there may be gains for your CPU in the future.”
[First day of miner optimization by NoodleDoodle, it is only May 1st]
-706: “The unstoppable NoodleDoodle has optimized the Windows build again. Hashrate should more than double. Windows is now faster than Linux. :O”
-753: “i here tft is no longer part of the project. so is he forking or relaunching bytecoin under new name and new parameters (merged mining with flatter emission curve.) also. what is the end consensus for the emission curve for monero. will it be adjusted."
[May, 5th 2014. TFT is launching FANTOMCOIN, a clone coin which its "only" feature was merged mining]
-761: ( [May, 5th 2014 – eizh on emission curve and tail emission]
-791: “As promised, I did Russian translation of main topic.”
[one among dozens of decentralized and “altruist” collaborators of Monero in minor tasks]
-827: image
-853: (
[some are not happy that NoodleDoodle had only released the built binaries, but not the source code]
-950: (
[Rias, an account suspected to be related to the Bytecoin scam, dares to tag Monero as “instamine”]
-957: “It's rather bizarre that you're calling this an "instamine" scam when you're so fervently supporting BCN, which was mined 80% before entering the clearnet. Difficulty adjustments are per block, so there is no possibility of an instamine unless you don't publish your blockchain (emission is regular at the preset interval, and scales adequately with the network hash rate). What you're accusing monero of is exactly what ByteCoin did.”
[Discussion with rias drags on for SEVERAL posts]
-1016: “There is no "dev team". There is a community of people working on various aspects of the coin.
I've been keeping the repo up to date. NoodleDoodle likes to optimise his miner. TFT started the fork and also assists when things break. othe's been working on a GUI. zone117x has been working on a pool.
It's a decentralized effort to maintain the fork, not a strawman team of leet hackers who dwell in the underbellies of the internet and conspire for instamines.”
-1023: “Like I stated in IRC, I am not part of the "dev team", I never was. Just so happens I took a look at the code and changed some extremely easy to spot "errors". I then decided to release the binary because I thought MRO would benefit from it. I made this decision individually and nobody else should be culpable”
[Noodledoodle gets rid of the instaminer accusations]
-1029: “I decided to relaunch Monero so it will suit all your wishes that you had: flatter emission curve, open source optimized miner for everybody from the start, no MM with BCN/BMR and the name. New Monero will be ready tomorrow”
[people trying to capitalize mistakes is always there.]
-1030: "Pull request has been submitted and merged to update miner speed
It appears from the simplicity of the fix that there may have been deliberate crippling of the hashing algorithm from introduction with ByteCoin."
[tacotime “officially” raises suspects of possible voluntarily crippled miner]
-1053: "I don't mind the 'relaunch' or the merge-mining fork or any other new coin at all. It's inevitable that the CryptoNote progresses like scrypt into a giant mess of coins. It's not undesirable or 'wrong'. Clones fighting out among themselves is actually beneficial for Monero. Although one of them is clearly unserious and trolling by choosing the same name.
Anyway, this sudden solidarity with BCN or TFT sure is strange when none of these accounts were around for the discussions that took place 3 weeks ago. Such vested interests with no prior indications. Hmm...? "
[eizh points out the apparent organized fudding]
-1061: "There was no takeover. The original developer (who himself did a fork of bytecoin and around a dozen lines of code changes) was non-responsive and had disappeared. The original name had been cybersquatted all over the place (since the original developer did not even register any domain name much less create a web site), making it impossible to even create a suitably named web site. A bunch of us who didn't want to see the coin die who represented a huge share of the hash power and ownership of the coin decided to adopt it. We reached out to the original developer to participate in this community effort and he still didn't respond over 24 hours, so we decided to act to save the coin from neglect and actively work toward building the coin."
[smooth defends legitimacy of current “dev team” and decisions taken]
-1074: “Zerocash will be announced soon (May 18 in Oakland? but open source may not be ready then?).
Here is a synopsis of the tradeoffs compared to CyptoNote: […]"
[comparison among Zerocash y Cryptonote]
-1083: "Altcoin history shows that except in the case of premine (Tenebrix), the first implementation stays the largest by a wide margin. We're repeating that here by outpacing Bytecoin (thanks to its 80% mine prior to surfacing). No other CN coin has anywhere near the hashrate or trading volume. Go check diff in Fantom for example or the lack of activity in BCN trading.
The only CN coin out there doing something valuable is HoneyPenny, and they're open source too. If HP develops something useful, MRO can incorporate it as well. Open source gives confidence. No need for any further edge."
[eizh reminds everyone the “first mover” advantage is a real advantage]
-1132: "I decided to tidy up bitmonero GitHub rep tonight, so now there is all valuable things from latest BCN commits & Win32. Faster hash from quazarcoin is also there. So BMR rep is the freshest one.
I'm working on another good feature now, so stay tuned."
[first TFT apparition in weeks, he somehow pretends to still be the "lead dev"]
-1139: "This is not the github or website used by Monero. This github is outdated even with these updates. Only trust binaries from the first post."
[eizh tries to clarify the community, after tft interference, which are the official downloads]
-1140: “The faster hash is from NoodleDoodle and is already submitted to the moner-project github ( and included in the binaries here.
[trying to bring TFT back on board] It would be all easier if you just work together with the other guys, whats the problem? Come to irc and talk like everyone else?
[on future monero exchangers] I got confirmation from one."
[8th may 2014, othe announces NoodleDoodle optimized miner is now open source, asks TFT to collaborate and communicates an exchanger is coming]
-1146: "I'll be impressed if they [BCN/TFT shills] manage to come up with an account registered before January, but then again they could buy those.”
-1150: “Ring signatures mean that when you sign a transaction to spend an output (coins), no one looking at the block chain can tell whether you signed it or one of the other outputs you choose to mix in with yours. With a mixing factor of 5 or 10 after several transactions there are millions of possible coins all mixed together. You get "anonymity" and mixing without having to use a third party mixer.”
[smooth answering to “what are ring signatures” in layman terms]
-1170: "Someone (C++ skilled) did private optimized miner a few days ago, he got 74H/s for i5 haswell. He pointed that mining code was very un-optimized and he did essential improvements for yourself. So, high H/S is possible yet. Can the dev's core review code for that?"
[forums are talking about an individual or group of individuals with optimized miners - may 9th 2014]
-1230: "Good progress on the pool reported by NOMP dev zone117x. Stay tuned, everyone.
And remember to email your favorite exchanges about adding MRO."
-1258: "This is actually as confusing to us as you. At one point, thankful_for_today said he was okay with name change:
Then he disappeared for more than a week after the merge mining vote failed.”
[eizh on the TFT-issue]
-1358: “Jadehorse: registered on 2014-03-06 and two pages of one line posts:;u=263597;u=263597;sa=showPosts
Trustnobody: registered on 2014-03-06 and two pages of one line posts:;u=264292;u=264292;sa=showPosts
You guys should really just stop trying. It is quite transparent what you are doing. Or if you want to do it, do it somewhere else. Everyone else: ignore them please."
[FUD campaign still ongoing, smooth battles it]
-1387: "The world’s first exchange for Monero just opened!"
[David Latapie announces an important milestone: exchanger is here]
-1467: "image"
[it is weird, but tft appears again, apparently as if he were in a parallel reality]
-1495: “”
[“trading” milestone reached: monero surpassed for first time 0.002 btc price]
-1513: "There is one and only one coin, formerly called Bitmonero, now called Monero. There was a community vote in favor (despite likely ballot stuffing against). All of the major stakeholders at the time agreed with the rename, including TFT.
The code base is still called bitmonero. There is no reason to rename it, though we certainly could have if we really wanted to.
TFT said he he is sentimental about the Bitmonero name, which I can understand, so I don't think there is any malice or harm in him continuing to use it. He just posted the nice hash rate chart on here using the old name. Obviously he understands that they are one and the same coin."
[Smooth clears up again the relation with TFT and BMR. Every time he appears it seems to generate confusion on newbies]
-1543: "Pool software is in testing now. You can follow the progress on the pool bounty thread (see original post on this thread for link)."
-1545: "[on the tail emission debate] I've been trying to raise awareness of this issue. The typical response seems to be, "when Bitcoin addresses the problem, so will we." To me this means it will never be addressed. The obvious solution is to perpetually increase the money supply, always rewarding miners with new coins.
Tacotime mentioned a hard fork proposal to never let the block reward drop below 1 coin:
Code: if (blockReward < 1){ blockReward = 1; }
I assume this is merely delaying the problem, however. I proposed a fixed annual debasement (say 2%) with a tx fee cap of like 0.001% of the current block reward (or whatever sounds reasonable). That way we still get the spam protection without worrying about fee escalation down the road."
[Johnny Mnemonic wants to debate tail emission. Debate is moved to the “Monero Economy” thread]
-1603: “My GOD,the wallet is very very wierd and too complicated to operate, Why dont release a wallet-qt as Bitcoin?”

-1611: "I like this about Monero, but it seems it was written by cryptographers, not programmers. The damned thing doesn't even compile on Arch, and there are several bugs, like command history not working on Linux. The crypto ideas are top-notch, but the implementation is not."

-1937: “[reference needed: smooth battling the weak evidence of optimized miner] Yes, I remember that. Some person on the Internet saying that some other unnamed person said he did something hardly constitutes evidence.
I'm not even doubting that optimized asm code could make a big difference. Just not sure how to know whether this is real or not. Rumors and FUD are rampant, so it is just hard to tell."

[smooth tries to bring lazybear and his optimized miner on board]
-1957: "smooth, NoodleDoodle just said on IRC his latest optimizations are 4x faster on Windows. Untested on Linux so far but he'll push the source to the git repo soon. We'll be at 1 million network hashrate pretty soon."

Please be patient. These are actual changes to the program, not just a switch that gets flicked on. It needs testing.”
[eizh has more info on last miner optimization]
-2023: “Monero marketcap is around $300,000 as of now”
-2059: I was skeptical of this conspiracy theory at first but after thinking about the numbers and looking back at the code again, I'm starting to believe it.
These are not deep optimizations, just cleaning up the code to work as intended.
At 100 H/s, with 500k iterations, 70 cycles per L3 memory access, we're now at 3.5 GHz which is reasonably close. So the algorithm is finally memory-bound, as it was originally intended to be. But as delivered by the bytecode developers not even close.
I know this is going to sound like tooting our own horn but this is another example of the kind of dirty tricks you can expect from the 80% premine crowd and the good work being done in the name of the community by the Monero developers.
Assuming they had the reasonable, and not deoptimized, implementation of the algorithm as designed all along (which is likely), the alleged "two year history" of bytecoin was mined on 4-8 PCs. It's really one of the shadiest and sleaziest premines scams yet, though this shouldn't be surprising because in every type of scam, the scams always get sneakier and more deceptive over time (the simple ones no longer work)."

So either a large botnet is mining, or someone's sitting quietly on a much more efficient miner and raking in MRO."
[with pools users start to notice that “avg” users account for a very small % of the network hashrate, either botnets or a super-optimized miner is mining monero]
-2137: “I figure its either:

[wolf0 is part of the monero community for a while, discussing several topics as botnet mining and miner optimizations. Now spots security flaws in the just launched pools]

-2323: "Monero is on Poloniex"
-2747: "Monero is holding a $500 logo contest on now:"
-2756: “So... ALL Pools have 50KH/s COMBINED.
Yet, network hash is 20x more. Am i the only one who thinks that some people are insta mining with prepared faster miners?”
-2757: “Pools aren't stable yet. They are more inefficient than solo mining at the moment. They were just released. 10x optimizations have already been released since launch, I doubt there is much more optimization left.”
-2765: “Penalty for too large block size is disastrous in the long run.
Once MRO value increases a lot, block penalties will become more critical of an issue. Pools will fix this issue by placing a limit on number and size of transactions. Transaction fees will go up, because the pools will naturally accept the most profitable transactions. It will become very expensive to send with more than 0 mixin. Anonymity benefits of ring signatures are lost, and the currency becomes unusable for normal transactions.”
-2773: "The CryptoNote developers didn't want blocks getting very large without genuine need for it because it permits a malicious attack. So miners out of self-interest would deliberately restrict the size, forcing the network to operate at the edge of the penalty-free size limit but not exceed it. The maximum block size is a moving average so over time it would grow to accommodate organic volume increase and the issue goes away. This system is most broken when volume suddenly spikes."
-3035: "We've contributed a massive amount to the infrastructure of the coin so far, enough to get recognition from cryptonote, including optimizing their hashing algorithm by an order of magnitude, creating open source pool software, and pushing several commits correcting issues with the coin that eventually were merged into the ByteCoin master. We also assisted some exchange operators in helping to support the coin.
To say that has no value is a bit silly... We've been working alongside the ByteCoin devs to improve both coins substantially."

-3068: "You are a little too caught up in the mindset of altcoin marketing wars about "unique features" and "the team" behind the latest pump and dump scam.
In fact this coin is really little more than BCN without the premine. "The team" is anyone who contributes code, which includes anyone contributing code to the BCN repository, because that will get merged as well (and vice-versa).
Focus on the technology (by all accounts amazing) and the fact that it was launched in a clean way without 80% of the total world supply of the coin getting hidden away "somewhere." That is the unique proposition here. There also happens to be a very good team behind the coin, but anyone trying too hard to market on the basis of some "special" features, team, or developer is selling you something. Hold on to your wallet."

-3283: "Most of the previous "CPU only" coins are really scams and the developers already have GPU miner or know how to write one. There are a very few exceptions, almost certainly including this one.
I don't expect a really dominant GPU miner any time soon, maybe ever. GPUs are just computers though, so it is certainly possible to mine this on a GPU, and there probably will be a some GPU miner, but won't be so much faster as to put small scale CPU miners out of business (probably -- absent some unknown algorithmic flaw).
Everyone focuses on botnets because it has been so long since regular users were able to effectively mine a coin (due to every coin rapidly going high end GPU and ASIC) that the idea that "users" could vastly outnumber "miners" (botnet or otherwise) isn't even on the radar.
The vision here is a wallet that asks you when you want to install: "Do you want to devote some of you CPU power to help secure the network. You will be eligible to receive free coins as a reward (recommended) [check box]." Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized.
That's what cryptonote wants to accomplish with this whole "egalitarian mining" concept. Whether it succeeds I don't know but we should give it a chance. Those cryptonote guys seem pretty smart. They've probably thought this through better than any of us have."

[Major FUD troll in the topic. One of the hardest I’ve ever seen]
-3571: "Tacotime wanted the thread name and OP to use the word privacy instead of anonymity, but I made the change for marketing reasons. Other coins do use the word anonymous improperly, so we too have to play the marketing game. Most users will not bother looking at details to see which actually has more privacy; they'll assume anonymity > privacy. In a world with finite population, there's no such thing as anonymity. You're always "1 of N" possible participants.
Zero knowledge gives N -> everyone using the currency, ring signatures give N -> your choice, and CoinJoin gives N -> people who happen to be spending around the same amount of money as you at around the same time. This is actually the critical weakness of CoinJoin: the anonymity set is small and it's fairly susceptible to blockchain analysis. Its main advantage is that you can stick to Bitcoin without hard forking.
Another calculated marketing decision: I made most of the OP about ring signatures. In reality, stealth addressing (i.e. one-time public keys) already provides you with 90% of the privacy you need. Ring signatures are more of a trump card that cannot be broken. But Bitcoin already has manual stealth addressing so the distinguishing technological factor in CryptoNote is the use of ring signatures.
This is why I think having a coin based on CoinJoin is silly: Bitcoin already has some privacy if you care enough. A separate currency needs to go way beyond mediocre privacy improvements and provide true indistinguishably. This is true thanks to ring signatures: you can never break the 1/N probability of guessing correctly. There's no additional circumstantial evidence like with CoinJoin (save for IP addresses, but that's a problem independent of cryptocurrencies)."

This is a dense digest of the first several thousand messages on the definitive Monero thread.
A lot of things happened in this stressful days and most are recorded here. It can be summarized in this:
  • 28th April: Othe and zone117x assume the GUI wallet and CN pools tasks.
  • 30th April: First NoodleDoodle's miner optimization.
  • 11th May: First Monero exchanger
  • 13th May: Open source pool code is ready.
  • 16th May: First pool mined block.
  • 19th May: Monero in poloniex
  • 20th May: Monero +1100 bitcoin 24h trading volume in Poloniex.
  • 21st May: New official miner optimization x4 speed (accumulated optimization x12-x16). Open source wolf0's CPU miner released.
  • 25th May: partnership with i2p
  • 28th May: The legendary super-optimized miner is leaked. Currently running x90 original speed. Hedge of the "cloud farmers" is over in the cpu mining.
  • 2nd June: Monero at last has a logo. Ticker symbol changes to the definitive XMR (former MRO)
  • 4th June: Claymore's open source GPU miner.
  • 10th June: Monero's "10,000 bitcoin pizza" (2500 XMR paintig). Deterministic seed-based wallets (recover wallet with a 24 word seed)
  • March 2015 – tail emission added to code
  • March 2016 – monero hard forks to 2 min block and doubles block reward
There basically two things in here that can be used to attack Monero:
  • Crippled miner Gave unfair advantage to those brave enough to risk money and time to optimize and mine Monero.
  • Fast curve emission non-bitcoin-like curve as initially advertised and as it was widely accepted as suitable
Though we have to say two things to support current Monero community and devs:
  • The crippled miner was coded either by Bytecoin or CryptoNote, and 100% solved within a month by Monero community
  • The fast curve emission was a TFT miscalculation. He forgot to consider that as he was halving the block target he was unintentionally doubling the emission rate.
