Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.

Need Help With my node

Hi guys!
My node seems to do well but it loses connection from quite often. Someone suggested me looking at debug.log file and I copied/pasted info once I got my node restarted. This line does not look good and it repeats quite a lot:

Do you have any suggestion other than rebooting my Raspi?

Thanks!

Is it normal for a new Full Node server to repeatedly show Potential Sale Tip detected messages? What does this even mean. I surprisingly can't find anything with a solution on the internet. Please look at my log dump and give me an idea what to do. Im trying to run a full node in service to the net

Here is my log messages:

this goes on until I decided just to shut down server after 24 hours and the .dat blockchain file was stuck at 16MB in size. Seemed like going nowhere.

Bitcoind stuck in startup loading block index

Hi,
I have had bitcoin core running on a raspberry pi for about 4 month now (followed the raspibolt instructions from stadicus) and it worked fine until 3 days ago it suddenly stopped working. With bitcoin-cli blockchaininfo i got
error code: -28 Loading block index... 
or something similar. When a looked in the debug log file i saw this:

After that there should follow a line about Loading the block index but it never appears.
It seems to be restarting without shutting down correctly, maybe it cannot find the block index? I tried reinstalling core, recreating the symlink to the hdd and resetting the service but nothing happened. Everytime it starts it gets stuck at the same point. It also takes an awful long time to stop bitcoind but i don't know if that is normal.
I found several people with similar problems online but noting helped so far. Has anyone had a similar problem in the past and found a solution to this?

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

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

https://www.youtube.com/watch?v=Snr5e8bzftI
This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

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

[DEVELOPMENT] Bitcoind IPV4 testnet port (18332) is failing to bind

[SOLVED] Thanks for everyone that have helped!


Hello everyone, this is a development problem that I'm currently having. Since the BTC Development sub is kind of inactive and I couldn't find any rule contraty to posting about BTC Development, I'll try my luck in here as I'm hopeless already. I've posted on BTC Stack Exchange but no answers also. Please, don't get me wrong, I'm trying to solve this problem for many days now, I've looked up everywhere for this.
I'm new to Bitcoin development and I'm currently having difficulties trying to make RPC calls from a Docker Container to a Bitcoin-Core daemon running in a SSH server. I suppose that the problem may be with Firewall or closed ports, but I also do not know much about Network settings.
I'm using nbobtc/bitcoind-php package to make the RPC calls with HTTP requests, and it is running in a Docker container. I'm sure the container is functional and is not the problem.
So here's what happening: when I run bitcoind in root user (but normal also won't work) in my SSH server, the IPV4 testnet port seems to be not opened. This message goes up when I run bitcoind:
Binding RPC on address 0.0.0.0 port 18332 failed.
Here's what my bitcoin.conf looks like (I want to use testnet in here). I'm using Bitcoin-Core "subversion": "Satoshi:0.17.1".
server=1 debug=net txindex=1 testnet=1 rpcuser=userb rpcpassword=test test.rpcport=18332 # I've already tried allowing the IP these 3 ways: # rpcallowip=192.168.xx.xx # My machine's IP # rpcallowip=172.19.x.x/xx # Docker's NBOBTC container IP # rpcallowip=0.0.0.0/0 # Allowing all IP datadir=/home/bitcoin-dev/.bitcoin debuglogfile=/home/bitcoin-dev/.bitcoin/debug.log 
Here's what appears in debug.log right after I run Bitcoind:

After all that appears above, there are just "UpdateTip", "Requesting block", "received block" and "getdata" messages. (so the P2P port, 18333, works).

And here is when I netstat:

sudo netstat -nap|grep bitcoin|grep LISTEN
tcp 0 0 0.0.0.0:18333 0.0.0.0:* LISTEN 31185/bitcoind tcp6 0 0 :::18332 :::* LISTEN 31185/bitcoind tcp6 0 0 :::18333 :::* LISTEN 31185/bitcoind 
Thank you in advance!

PS: A few days ago I could make it work when running bitcoind with root user, but now even that won't solve the problem.

Compiling instructions?

Could we get some compiling instructions for Bitcoin SV? I'm having a hard time compiling it to run on my server alongside a bitcoin node. When I try to start it up after compiling, it says unable to start HTTP server. Also, the wallet functions are limited because for whatever reason I can't get it to use the Berkeleys DB.

Please post some terminal commands for Ubuntu/Debian based installation :) thanks

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

This tutorial has been updated: https://www.reddit.com/reddCoin/comments/a0wn1v/updated_staking_reddcoin_core_client_gui_wallet/.
   

Intro

I want to stake Reddcoins on my Raspberry Pi, but there is no easy to install package for the Reddcoin Core client. I found some tutorials (mentioned at the bottom, under 'credits'), but I still struggled to get the result I wanted. It took some small adjustments, but I got the GUI Wallet of Reddcoin Core working on my Raspberry Pi Model 3B. See the steps below. :).
 
If you have any questions or comments, please post a comment in this thread, so others can also benefit from it.
 
If you would like to tip me: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
   
Even though Raspbian is the primary OS for the Raspberry Pi, it seems that it's not possible to build and compile the Reddcoin wallet software for Raspbian Stretch. However, I got the wallet compiled using Ubuntu MATE.

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

Hi!
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 raspnode.com - 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 http://raspnode.com/diyBitcoin.html 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)

PART ONE

This is the manual how to get started on you PC / MAC / Linux (I did it on Win7)
Go to: https://bitcoin.org/en/download 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
datadir=l:\yourfolder
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:
dbcache=4096
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:
prune=550
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.

PART 2

Here is what I did:
1) I installed Raspian Pixel (https://www.raspberrypi.org/downloads/raspbian/) 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:
http://raspnode.com/diyBitcoin.html
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped.
On Tutorial Page: Start with RASPBIAN (OPTIONAL) CONFIG OPTIONS.
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 http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz [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 https://github.com/bitcoin/bitcoin.git cd bitcoin ./autogen.sh
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 https://github.com/bitcoin/bitcoin.git

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)
prune=550
That's it for the raspi.
update: To signal UASF enter in a new line:
uacomment=UASF-SegWit-BIP148

TRANSFER

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: https://winscp.net/eng/download.php
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
.bitcoin
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 192.168.1.1) and enable portforwarding for your raspberry pi - and open ports 8333 - that's it!
You can now go to: https://bitnodes.21.co/nodes/
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 @ https://bitcoin.org/de/download
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 https://github.com/bitcoin/bitcoin.git )
  • 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)

Step by step in staking Redd with Raspberry Pi 3

Before I start, I would like to pay complete credits to these two guys :)
https://www.reddcointalk.org/topic/2679/reddcoin-staking-via-ubuntu-mate-on-raspberry-pi-3-model-b-march-2018 (most of my steps, if not all, are from this link)
https://github.com/joroob/reddcoin/blob/mastedoc/build-arm.md
All the steps I am writing is ABSOLUTELY NECESSARY, please don't try to skip it because I did, and it doesn't work.
step 1: get a Raspberry Pi B https://www.raspberrypi.org/products/#buy-now-modal
step 2: make sure you get proper power supply 5v 2A - the Pi will mine, it will need sufficient power. Regular USB samsung charger will not work.
step 3: get proper micro SD card (SanDisk for example) 32Gb++
step 4: USB + Mouse keyboard
step 5: flash micro SD card with Ubuntu MATE
Download Ubuntu Mate image: https://ubuntu-mate.org/raspberry-pi/
Download Etcher: https://etcher.io
After finishing downloading, use Etcher to write/flash the image on micro SD card
After this, your SD card contains Ubuntu MATE OS.
step 6: Place SD Card into Raspberry Pi 3 and start it up. You should be able to see Ubuntu OS! Congrats!
step 7: Connect to wifi or internet cable (internet is better and faster)
step 8: OPTIONAL - turn off UI OS, so that things will work faster
Open XTerminal:
sudo systemctl disable lightdm.service (to turn UI off) 
in case you want to turn UI on again, run this:
sudo systemctl start lightdm.service (to turn UI on) 
step 9: install all dependencies
sudo apt-get update && sudo apt-get install git build-essential libqt4-dev libprotobuf-dev protobuf-compiler libtool autotools-dev autoconf libssl-dev libboost-all-dev wget pkg-config sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install db4.8 sudo apt-get install libminiupnpc-dev sudo apt-get install libqrencode-dev Reboot 
step 10: add additional RAM (sort of) in case the App need it, this is call "Create Swap file"
sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo ‘/swapfile none swap sw 0 0’ | sudo tee -a /etc/fstab 
step 11: Build Berkeley Database
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar xfvz db-4.8.30.NC.tar.gz cd db-4.8.30.NC cd build_unix ../dist/configure --enable-cxx make sudo make install 
step 11.5: Set BerkeleyDB path
export CPATH="/uslocal/BerkeleyDB.4.8/include" export LIBRARY_PATH="/uslocal/BerkeleyDB.4.8/lib" export LD_LIBRARY_PATH=/uslocal/BerkeleyDB.4.8/lib/ 
step 12: Build Reddcoin Wallet
---download source code ---- only source from joroob/reddcoin will work because some stweak was needed for ARM CPU
cd ~ git clone https://github.com/joroob/reddcoin.git 
---build reddcoin ----
cd reddcoin ./autogen.sh ./configure --with-gui=no --disable-tests cd src make sudo make install 
If you finish this, you are in a great position!!!
step 13: Create reddcoin configuration file
cd ~ mkdir .reddcoin && cd .reddcoin nano reddcoin.conf rpcuser=YOUR OWN USERNAME, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT rpcpassword=YOUR OWN PASS WORD, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT 
step 14: Use bootstrap
(At this point, you had a running reddcoin daemon, now you can start staking. But syncing the full chain takes long time.)
cd ~/.reddcoin wget https://github.com/reddcoin-project/reddcoin/releases/download/v2.0.1.2/bootstrap.dat.xz xz -d bootstrap.dat.xz 
step 15: start the reddcoin daemon service cd ~/reddcoin/src ./reddcoind -daemon
After this, you can test if the daemon is working, by perform this command: ./reddcoin-cli getblockcount
step 16: if your app is not able to sync, it is probably the firewall issue with OS, run this to allow port 45444 (used by Reddcoin) and redo step 15
sudo iptables -I INPUT 1 -i eth0 -p tcp --dport 45444 -j ACCEPT sudo iptables -A OUTPUT -p tcp --dport 45444 -j ACCEPT 
step 17: open BEER and enjoy! This is a MUST or the daemon will stop working! I am not kidding!
step 18: Actually, i forgot to mention you need to execute this command for the wallet to stake:
reddcoind walletpassphrase $yourpassword 9999999 true 
ADDITIONAL REMARKS:
From my PC: I am using putty to execute the command, winSCP to monitor the file location on raspberry.
Moving Red Coins out of exchange really a big move, start with normal wallet, don't start with this tutorial :) Ever since I move my coins out of exchange, I am free from all of the ups and downs! Really!
So guys and gals, Redd On!
UPDATE 18 Mar: my first stake has arrived after 6 days staking :)
In case you want to tip me: RaF3TeWqgTzAdnaZQffnsxS74dag13zsAY
Edit 1: Format stuff
Edit 2: Add step 18 to execute staking command.
Edit 3: In case you don't want to compile the source code, you can download my compile version here: https://github.com/hieplenet/reddcoin/releases/tag/v2.0.0.0 (but doing this, you should be aware of the risk of me changing source code for my benefit - I don't change any thing, but you should be cautious, this is the internet :) )

Discord Log from Ravencoin Open Developer Meeting - Oct 5, 2018

joey at 1:57 PM

What kind of transaction types are possible with RVN assets? Is it possible to create an asset that has a set lifetime or self-destruct time?

Tron at 2:00 PM

Not for assets/sub-assets/unique. We might be able to do that with voting tokens.

RavencoinDev at 2:01 PM

Hello Everybody!📷1

SpyderDev at 2:01 PM

Hi boss📷1

[Dev] Blondfrogs at 2:01 PM

SUP📷1

Chatturga at 2:01 PM

^📷1

BruceFenton at 2:01 PM

Probably lots of ways to do a self destruct on second layer as well if desired

russ at 2:01 PM

suuuuuupso what is todays topic?

RavencoinDev at 2:02 PM

Thanks for joining us today. We would like to discuss the current status of the 2.1 release.As well as doing an open Q&A at the end.First though I want to thank everybody that helped get the word out on upgrading to the 2.0.4.1 release!Without that fix being in place and exchanges and pools upgrading we would be having a different conversation today.This community is amazing.

russ at 2:04 PM

we would have ended up like pigeoncoinnot a good look📷2

watsure at 2:05 PM

Hello Mr. God

RavencoinDev at 2:05 PM

Exactly

russ at 2:05 PM

i gave pigeoncoin the pullrequest but they ignored meglad we have competent devs

[Dev] Blondfrogs at 2:05 PM

Everyone, So we are planning on getting out build 2.1 as soon as possible. We are still doing bug fixes, and getting the code hardened for release. There is currently one bug is the asset layer that we are fixing right now, and once that is done we should have a couple days of testing. It would be lovely if the community helped with testing, and we appreciate all of the testing that the community has already done. Once, we have a basic build that is tested, we are going to make a public release and notify the miners and pools.

RavencoinDev at 2:06 PM

Once that bug is addressed a release branch will be created.

russ at 2:06 PM

that duplicate ownership asset bug is nasty

RavencoinDev at 2:06 PM

You should all be able to build that and jump on testnet.

[Dev] Blondfrogs at 2:07 PM

@russ Yeah, didn't see that one. BUt I have a fix right now that seems to be working on my local machine

RavencoinDev at 2:07 PM

We need as much testing help from our devs as possible.

[Dev] Blondfrogs at 2:07 PM

so, I will have that pushed up with the day.

russ at 2:07 PM

nice

[Dev] Blondfrogs at 2:08 PM

Just a reminder, that when the new wallet is published, if you don't update your wallet by the time assets are voting in by the blocks you will fork. So, we are going to try and get the wallet out there as soon as we can so users have weeks to upgrade.

Skan at 2:09 PM

Hey everyone

RavencoinDev at 2:10 PM

Any questions comments about the 2.1 release?

Skan at 2:10 PM

Mojave support?

SpyderDev at 2:10 PM

Yes and no

RavencoinDev at 2:10 PM

Good question SkanRight now that's also an issue with Bitcoin.

SpyderDev at 2:12 PM

The short version for Mojave is that the released binaries will work fine.

Skan at 2:12 PM

Interesting, so is it likely going to be a future upgrade that brings stability?

SpyderDev at 2:12 PM

However, developers should hold off.

RavencoinDev at 2:12 PM

We are currently building on High Sierra

Skan at 2:12 PM

Ok good to know for those who ask

SpyderDev at 2:13 PM

There is an incompatibility with Berkeley db version 4 that causes a segfault on init.

RavencoinDev at 2:13 PM

Or using the build scripts that Under created to build on Linux. Thjanks @Under

[Master] Roshii at 2:13 PM

Looks I'm late to the event

[Dev] Blondfrogs at 2:13 PM

THE MASTER!

RavencoinDev at 2:13 PM

Sorry it's late for you @[Master] Roshii

Skan at 2:14 PM

master roshi is never late, he is simply the turtle hermit

SpyderDev at 2:14 PM

One can upgrade Berkeley-db to the latest version and compile with the --incompatible-bdb and things will run, but there are some unknowns as far as wallet compatibility is concerned.

RavencoinDev at 2:15 PM

Raven will likely follow Bitcoin on Mojave support.

SpyderDev at 2:15 PM

The release binaries are compiled on Linux which we have tested on Mojave, so as long as you aren't compiling binaries go ahead and update to Mojave

RavencoinDev at 2:15 PM

It's a problem they have to solve as well, so...

SpyderDev at 2:15 PM

There is supposed to be a patch to bdb, but so far it isn't working

[Master] Roshii at 2:15 PM

@RavencoinDev it's never late for me.

Skan at 2:15 PM

Ok, and for the devs interested just point them to the berkeley upgrade with some warnings or to Under's scripts?

RavencoinDev at 2:16 PM

Right, the wallet runs just fine on Mojave. It's just a developer issue.

[Master] Roshii at 2:16 PM

If I can say anything it will be : don't update to Mojave

SpyderDev at 2:16 PM

There is a warning note in the docs section for OSX building

RavencoinDev at 2:16 PM

Mojave slowed down @[Master] Roshii and the iOS wallet.

Skan at 2:16 PM

YikesOk good to know, just want to be able to help / point people in the right direction

RavencoinDev at 2:17 PM

Thanks @Skan

SpyderDev at 2:17 PM

There is also an issue with Mojave dark mode and the QT wallet that makes things difficult to read (white on white text). We have a workaround which is to disable dark mode for QT in the plist file.

Skan at 2:17 PM

Ok so this is going to be pretty soon then, right ? Next week, likely?

RavencoinDev at 2:18 PM

Any further Mojave questions?Which @Skan ?

Skan at 2:18 PM

I think that covers it for me2.1 releaseIn order to have weeks to upgrade before main net

RavencoinDev at 2:18 PM

Yes, it is looking like we can work through this last issue with asset re-org very soon.Likely early next week.

Skan at 2:20 PM

Is 2.1 going to have any UI updates ?

RavencoinDev at 2:20 PM

Yes, frogs has more details.

[Dev] Blondfrogs at 2:20 PM

The UI is done. It is currently in the develop2. So if you have built the develop2 branch, you would be looking at the new UI for now.

RavencoinDev at 2:21 PM

There have been other QT designs kicked around and we would love to see more from the community.

[Dev] Blondfrogs at 2:21 PM

Future upgrades to come though. but those won't be mandatory upgrades. Just visual upgrades.

SpyderDev at 2:21 PM

The UI tweaks are subtle, but they make a big difference.

Skan at 2:22 PM

Very cool, I will check out dev2 branch

russ at 2:22 PM

new asset creation UI is awesome

Skan at 2:22 PM

I saw that, I like it. And the longer asset holdings list

RavencoinDev at 2:22 PM

@russ Don't make @[Dev] Blondfrogs head any larger...

russ at 2:23 PM

lol

RavencoinDev at 2:23 PM

Other 2.1 release questions/comments?

Skan at 2:23 PM

Cant think of anything else at the momentThanks!

Hans_Schmidt at 2:23 PM

Is dividend support officially part of 2.1 release? It wasn't intuitive to me how that works.

RavencoinDev at 2:24 PM

No it will be in the next release. However, you could write a script that would provide the same functionality with what will be released in 2.1.

Skan at 2:25 PM

I heard something about Phase 4 being complete already, is that true, and is that in 2.1?

RavencoinDev at 2:25 PM

List all addresses with an asset, loop through sending X raven to each.

Skan at 2:25 PM

Unique assets>

RavencoinDev at 2:25 PM

Yes, Unique assets are complete.(edited)

Tron at 2:25 PM

Dividend support can be done without modifying the protocol. We can add it to a version of the software that can be used by the payer, without requiring others to upgrade.So we did phase 1, 2, 4

Skan at 2:26 PM

Oh wowGreat job everyone!

RavencoinDev at 2:26 PM

Yeah, we're super excited about the use cases that assets and unique assets provide to our develoepers(edited)

Skan at 2:27 PM

Can you tell us anything else about this separate software client? Will it be geared more towards enterprise use in general or will it just be that feature?

RavencoinDev at 2:27 PM

Speaking of, do any of you have a dev project in the works with assets?

russ at 2:27 PM

well its not a separate software client, its a backwards compatible release @Skan(edited)kind of like a softfork if you know what that is

Skan at 2:28 PM

Yeah unique assets will be awesome, actually there's a korean community member planning on issuing them along with silver ravencoinsIf im not mistaken

RavencoinDev at 2:28 PM

That's awesome!

russ at 2:28 PM

@RavencoinDev @Scotty is working on an asset explorerhttp://ravencoin.asset-explorer.net/

RavencoinDev at 2:29 PM

Yes, we've been watching that.

Skan at 2:29 PM

I am working with him on a Korean translation of the whitepaper, x16r whitepaper, and an introduction article so that we can take advantage of our availability in that market📷1

RavencoinDev at 2:29 PM

Super excited to see that mature.

Skan at 2:29 PM

@russ ah ok that makes senseWill there be anything else to that release?

RavencoinDev at 2:30 PM

Thanks @Skan. We want Raven to span the globe.Okay, Open Q&A time.What other questions do you guys have?

Skan at 2:31 PM

This release with rewards capability, will there be anything else added/changed for that version?

Tron at 2:31 PM

It might be released as phase 3, 5, 6.Although it could be released separately, without impacting anything.

Skan at 2:32 PM

Ah ok, so all of these features can be opted-into by someone who wants to take advantage, without cluttering the experience for a basic user

Tron at 2:32 PM

Phase 5 and 6 will be together as it requires a hard-fork.

RavencoinDev at 2:33 PM

Yes, we want to focus on user experience so it's super simple to do what you want to do.

Skan at 2:33 PM

Awesome

russ at 2:33 PM

so is anyone working on RSK yet

[Dev] Blondfrogs at 2:34 PM

We aren't yet.

russ at 2:34 PM

yea im gonna have a look at the code soon

[Master] Roshii at 2:34 PM

Who said ravencoin needs RSK

RavencoinDev at 2:34 PM

It'd be great to have that done by the community.

russ at 2:34 PM

i think some people would like smart contracts @[Master] Roshii

Skan at 2:35 PM

RSK would be great for token distributions

russ at 2:35 PM

the real trick would be getting RSK to recognize assets

Tron at 2:35 PM

RSK, Segwit, Lightning are all on the table, but lower priority than phases 3, 5, 6.

[Master] Roshii at 2:35 PM

This is just like saying let's do what ravencoin does in the old fassion!

russ at 2:35 PM

well not really, smart contracts can do other things

[Master] Roshii at 2:36 PM

What's the RBF status @Tron

Skan at 2:36 PM

Keep us posted russ I think that would be amazingWhen you write smart contracts in RSK what language is it in?

russ at 2:36 PM

solidity i thinlthink

RavencoinDev at 2:36 PM

yes

russ at 2:36 PM

eth contracts also work on RSKso thats a plus

Skan at 2:37 PM

Ok great so we dont even have to work on templates or anything

RavencoinDev at 2:37 PM

Having solidity contracts that interact with Raven assets would open up a lot of possibilities.

Skan at 2:37 PM

I think so too, especially for stuff like tokens in gaming use case📷1

russ at 2:37 PM

i guess it would also help with cross chain atomic swaps too

Skan at 2:37 PM

Yep

RavencoinDev at 2:37 PM

Yes!

russ at 2:38 PM

BTC directly for an asset

Skan at 2:38 PM

sounds like a good product

russ at 2:38 PM

making ICOs easier

Tron at 2:38 PM

Yes, cross-chain atomic swaps would be amazing with user issued assets.

RavencoinDev at 2:39 PM

Other questions?

Skan at 2:40 PM

Smart contract atomic swap erc20token 1:1 for their new RVN counterpart

Hans_Schmidt at 2:40 PM

I believe that every cross-chain atomic swap implementation I have seen requires a trusted federation. That's even true for RSK.

Tron at 2:40 PM

@Skan I like it!

Skan at 2:42 PM

No more questions from me

RavencoinDev at 2:42 PM

Okay, seems that we're winding down on the Q&A.Thank you all for joining us today. I've really liked how this discussion has worked out on Discord.Did anybody miss IRC today?

russ at 2:43 PM

hell no

Hans_Schmidt at 2:43 PM

Like a toothache

russ at 2:43 PM

this was waaay better

RavencoinDev at 2:44 PM

📷

Hans_Schmidtat 2:44 PM

Missed the mems tho

RavencoinDevToday at 2:44 PM

I agree. I was even able to fix my typos.That's right, we had some epic memes last time.Where are you @Pathfinder

Chatturga at 2:45 PM

@Pathfinder Do you have an epic meme for us today?

Skan at 2:45 PM

Meme please

[Master] Roshii at 2:46 PM

Can somebody give @Pathfinder a Master Memer role and color

Nexus 101:

1. What is Nexus (NXS)?
Nexus is a digital currency, distributed framework, and peer-to-peer network. Nexus further improves upon the blockchain protocol by focusing on the following core technological principles:
Nexus will combine our in-development quantum-resistant 3D blockchain software with cutting edge communication satellites to deliver a free, distributed, financial and data solution. Through our planned satellite and ground-based mesh networks, Nexus will provide uncensored internet access whilst bringing the benefits of distributed database systems to the world.

2. What benefits does Nexus bring to the blockchain space?
As Nexus has been developed, an incredible amount of time has been put into identifying and solving several key limitations:
Nexus is also developing a framework called the Lower Level Library. This LLL will incorporate the following improvements:
For information about more additions to the Lower Level Library, please visit here
 
3. How does Nexus secure the network and reach consensus?
Nexus is unique amongst blockchain technology in that Nexus uses 3 channels to secure the network against attack. Whereas Bitcoin uses only Proof-of-Work to secure the network, Nexus combines a prime number channel, a hashing channel and a Proof-of-Stake channel. Where Bitcoin has a difficulty adjustment interval measured in weeks, Nexus can respond to increased hashrate in the space of 1 block and each channel scales independently of the other two channels. This stabilizes the block times at ~50 seconds and ensures no single channel can monopolize block production. This means that a 51% attack is much more difficult to launch because an attacker would need to control all 3 channels.
Every 60 minutes, the Nexus protocol automatically creates a checkpoint. This prevents blocks from being created or modified dated prior to this checkpoint, thus protecting the chain from malicious attempts to introduce an alternate blockchain.
 
4. What is quantum resistance and how does Nexus implement it?
To understand what quantum resistance is and why it is important, you need to understand how quantum computing works and why it’s a threat to blockchain technology. Classical computing uses an array of transistors. These transistors form the heart of your computer (the CPU). Each transistor is capable of being either on or off, and these states are used to represent the numerical values 1 and 0.
Binary digits’ (bits) number of states depends on the number of transistors available, according to the formula 2n, where n is the number of transistors. Classical computers can only be in one of these states at any one time, so the speed of your computer is limited to how fast it can change states.
Quantum computers utilize quantum bits, “qubits,” which are represented by the quantum state of electrons or photons. These particles are placed into a state called superposition, which allows the qubit to assume a value of 1 or 0 simultaneously.
Superposition permits a quantum computer to process a higher number of data possibilities than a classical computer. Qubits can also become entangled. Entanglement makes a qubit dependant on the state of another, enabling quantum computing to calculate complex problems, extremely quickly.
One such problem is the Discrete Logarithm Problem which elliptic curve cryptography relies on for security. Quantum computers can use Shor’s algorithm to reverse a key in polynomial time (which is really really really fast). This means that public keys become vulnerable to quantum attack, since quantum computers are capable of being billions of times faster at certain calculations. One way to increase quantum resistance is to require more qubits (and more time) by using larger private keys:
Bitcoin Private Key (256 bit) 5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF
Nexus Private Key (571 bit) 6Wuiv513R18o5cRpwNSCfT7xs9tniHHN5Lb3AMs58vkVxsQdL4atHTF Vt5TNT9himnCMmnbjbCPxgxhSTDE5iAzCZ3LhJFm7L9rCFroYoqz
Bitcoin addresses are created by hashing the public key, so it is not possible to decrypt the public key from the address; however, once you send funds from that address, the public key is published on the blockchain rendering that address vulnerable to attack. This means that your money has higher chances of being stolen.
Nexus eliminates these vulnerabilities through an innovation called signature chains. Signature chains will enable access to an account using a username, password and PIN. When you create a transaction on the network, you claim ownership of your signature chain by revealing the public key of the NextHash (the hash of your public key) and producing a signature from the one time use private key. Your wallet then creates a new private/public keypair, generates a new NextHash, including the corresponding contract. This contract can be a receive address, a debit, a vote, or any other type of rule that is written in the contract code.
This keeps the public key obscured until the next transaction, and by divorcing the address from the public key, it is unnecessary to change addresses in order to change public keys. Changing your password or PIN code becomes a case of proving ownership of your signature chain and broadcasting a new transaction with a new NextHash for your new password and/or PIN. This provides the ability to login to your account via the signature chain, which becomes your personal chain within the 3D chain, enabling the network to prove and disprove trust, and improving ease of use without sacrificing security.
The next challenge with quantum computers is that Grover’s algorithm reduces the security of one-way hash function by a factor of two. Because of this, Nexus incorporates two new hash functions, Skein and Keccak, which were designed in 2008 as part of a contest to create a new SHA3 standard. Keccak narrowly defeated Skein to win the contest, so to maximize their potential Nexus combines these algorithms. Skein and Keccak utilize permutation to rotate and mix the information in the hash.
To maintain a respective 256/512 bit quantum resistance, Nexus uses up to 1024 bits in its proof-of-work, and 512 bits for transactions.
 
5. What is the Unified Time protocol?
All blockchains use time-stamping mechanisms, so it is important that all nodes operate using the same clock. Bitcoin allows for up to 2 hours’ discrepancy between nodes, which provides a window of opportunity for the blockchain to be manipulated by time-related attack vectors. Nexus eliminates this vulnerability by implementing a time synchronization protocol termed Unified Time. Unified Time also enhances transaction processing and will form an integral part of the 3D chain scaling solution.
The Unified Time protocol facilitates a peer-to-peer timing system that keeps all clocks on the network synchronized to within a second. This is seeded by selected nodes with timestamps derived from the UNIX standard; that is, the number of seconds since January 1st, 1970 00:00 UTC. Every minute, the seed nodes report their current time, and a moving average is used to calculate the base time. Any node which sends back a timestamp outside a given tolerance is rejected.
It is important to note that the Nexus network is fully synchronized even if an individual wallet displays something different from the local time.
 
6. Why does Nexus need its own satellite network?
One of the key limitations of a purely electronic monetary system is that it requires a connection to the rest of the network to verify transactions. Existing network infrastructure only services a fraction of the world’s population.
Nexus, in conjunction with Vector Space Systems, is designing communication satellites, or cubesats, to be launched into Low Earth Orbit in 2019. Primarily, the cubesat mesh network will exist to give Nexus worldwide coverage, but Nexus will also utilize its orbital and ground mesh networks to provide free and uncensored internet access to the world.
 

The Nexus Currency (NXS):

1. How can I get Nexus?
There are two ways you can obtain Nexus. You can either buy Nexus from an exchange, or you can run a miner and be rewarded for finding a block. If you wish to mine Nexus, please follow our guide found below.
Currently, Nexus is available on the following exchanges:
Nexus is actively reaching out to other exchanges to continue to be listed on cutting edge new financial technologies..
 
2. How much does a transaction cost?
Under Nexus, the fee structure for making a transaction depends on the size of your transaction. A default fee of 0.01 NXS will cover most transactions, and users have the option to pay higher fees to ensure their transactions are processed quickly.
When the 3D chain is complete and the initial 10-year distribution period finishes, Nexus will absorb these fees through inflation, enabling free transactions.
 
3. How fast does Nexus transfer?
Nexus reaches consensus approximately every ~ 50 seconds. This is an average time, and will in some circumstances be faster or slower. NXS currency which you receive is available for use after just 6 confirmations. A confirmation is proof from a node that the transaction has been included in a block. The number of confirmations in this transaction is the number that states how many blocks it has been since the transaction is included. The more confirmations a transaction has, the more secure its placement in the blockchain is.
 
4. Did Nexus hold an ICO? How is Nexus funded?
The Nexus Embassy, a 501(C)(3) not-for-profit corporation, develops and maintains the Nexus blockchain software. When Nexus began under the name Coinshield, the early blocks were mined using the Developer and Exchange (Ambassador) addresses, which provides funding for the Nexus Embassy.
The Developer Fund fuels ongoing development and is sourced by a 1.5% commission per block mined, which will slowly increase to 2.5% after 10 years. This brings all the benefits of development funding without the associated risks.
The Ambassador (renamed from Exchange) keys are funded by a 20% commission per block reward. These keys are mainly used to pay for marketing, and producing and launching the Nexus satellites.
When Nexus introduces developer and ambassador contracts, they will be approved, denied, or removed by six voting groups namely: currency, developer, ambassador, prime, hash, and trust.
Please Note: The Nexus Embassy reserves the sole right to trade, sell and or use these funds as required; however, Nexus will endeavor to minimize the impact that the use of these funds has upon the NXS market value.
 
5. Is there a cap on the number of NXS in existence?
After an initial 10-year distribution period ending on September 23rd, 2024, there will be a total of 78 million NXS. Over this period, the reward gradient for mining Nexus follows a decaying logarithmic curve instead of the reward halving inherent in Bitcoin. This avoids creating a situation where older mining equipment is suddenly unprofitable, encouraging miners to continue upgrading their equipment over time and at the same time reducing major market shocks on block halving events.
When the distribution period ends, the currency supply will inflate annually by a maximum of 3% via staking and by 1% via the prime and hashing channels. This inflation is completely unlike traditional inflation, which degrades the value of existing coins. Instead, the cost of providing security to the blockchain is paid by inflation, eliminating transaction fees.

6. What is the difference between the LLD wallet and the Oracle wallet?
Due to the scales of efficiency needed by blockchain, Nexus has developed a custom-built database called the Lower Level Database. Since the development of the LLD wallet 0.2.3.1, which is a precursor to the Tritium updates, you should begin using the LLD wallet to take advantage of the faster load times and improved efficiency.
The Oracle wallet is a legacy wallet which is no longer maintained or updated. It utilized the Berkeley DB, which is not designed to meet the needs of a blockchain. Eventually, users will need to migrate to the LLD wallet. Fortunately, the wallet.dat is interchangeable between wallets, so there is no risk of losing access to your NXS.
 
7. How do I change from Oracle to the LLD wallet?
Step 1 - Backup your wallet.dat file. You can do this from within the Oracle wallet Menu, Backup Wallet.
Step 2 - Uninstall the Oracle wallet. Close the wallet and navigate to the wallet data directory. On Windows, this is the Nexus folder located at %APPDATA%\Nexus. On macOS, this is the Nexus folder located at ~/Library/Application Support/Nexus. Move all of the contents to a temporary folder as a backup.
Step 3 - Copy your backup of wallet.dat into the Nexus folder located as per Step 2.
Step 4 - Install the Nexus LLD wallet. Please follow the steps as outlined in the next section. Once your wallet is fully synced, your new wallet will have access to all your addresses.
 
8. How do I install the Nexus Wallet?
You can install your Nexus wallet by following these steps:
Step 1 - Download your wallet from www.nexusearth.com. Click the Downloads menu at the top and select the appropriate wallet for your operating system.
Step 2 - Unzip the wallet program to a folder. Before running the wallet program, please consider space limitations and load times. On the Windows OS, the wallet saves all data to the %APPDATA%\Nexus folder, including the blockchain, which is currently ~3GB.
On macOS, data is saved to the ~/Library/Application Support/Nexus folder. You can create a symbolic link, which will allow you to install this information in another location.
Using Windows, follow these steps:
On macOS, follow these steps:
Step 3 (optional) - Before running the wallet, we recommend downloading the blockchain database manually. Nexus Earth maintains a copy of the blockchain data which can save hours from the wallet synchronization process. Please go to www.nexusearth.com and click the Downloads menu.
Step 4 (optional) - Extract the database file. This is commonly found in the .zip or .rar format, so you may need a program like 7zip to extract the contents. Please extract it to the relevant directory, as outlined in step 2.
Step 5 - You can now start your wallet. After it loads, it should be able to complete synchronization in a short time. This may still take a couple of hours. Once it has completed synchronizing, a green check mark icon will appear in the lower right corner of the wallet.
Step 6 - Encrypt your wallet. This can be done within the wallet, under the Settings menu. Encrypting your wallet will lock it, requiring a password in order to send transactions.
Step 7 - Backup your wallet.dat file. This can be done from the File menu inside the wallet. This file contains the keys to the addresses in your wallet. You may wish to keep a secure copy of your password somewhere, too, in case you forget it or someone else (your spouse, for example) ever needs it.
You should back up your wallet.dat file again any time you create – or a Genesis transaction creates (see “staking” below) – a new address.
 

Types of Mining or Minting:

1.Can I mine Nexus?
Yes, there are 2 channels that you can use to mine Nexus, and 1 channel of minting:
Prime Mining Channel
This mining channel looks for a special prime cluster of a set length. This type of calculation is resistant to ASIC mining, allowing for greater decentralization. This is most often performed using the CPU.
Hashing Channel
This channel utilizes the more traditional method of hashing. This process adds a random nonce, hashes the data, and compares the resultant hash against a predetermined format set by the difficulty. This is most often performed using a GPU.
Proof of Stake (nPoS)
Staking is a form of mining NXS. With this process, you can receive NXS rewards from the network for continuously operating your node (wallet). It is recommended that you only stake with a minimum balance of 1000 NXS. It’s not impossible to stake with less, but it becomes harder to maintain trust. Losing trust resets the interest rate back to 0.5% per annum.
 
2. How do I mine Nexus?
As outlined above, there are two types of mining and 1 proof of stake. Each type of mining uses a different component of your computer to find blocks, the CPU or the GPU. Nexus supports CPU and GPU mining on Windows only. There are also third-party macOS builds available.
Please follow the instructions below for the relevant type of miner.
 
Prime Mining:
Almost every CPU is capable of mining blocks on this channel. The most effective method of mining is to join a mining pool and receive a share of the rewards based on the contribution you make. To create your own mining facility, you need the CPU mining software, and a NXS address. This address cannot be on an exchange. You create an address when you install your Nexus wallet. You can find the related steps under How Do I Install the Nexus Wallet?
Please download the relevant miner from http://nexusearth.com/mining.html. Please note that there are two different miner builds available: the prime solo miner and the prime pool miner. This guide will walk you through installing the pool miner only.
Step 1 - Extract the archive file to a folder.
Step 2 - Open the miner.conf file. You can use the default host and port, but these may be changed to a pool of your choice. You will need to change the value of nxs_address to the address found in your wallet. Sieve_threads is the number of CPU threads you want to use to find primes. Ptest_threads is the number of CPU threads you want to test the primes found by the sieve. As a general rule, the number of threads used for the sieve should be 75% of the threads used for testing.
It is also recommended to add the following line to the options found in the .conf file:
"experimental" : "true"
This option enables the miner to use an improved sieve algorithm which will enable your miner to find primes at a faster rate.
Step 3 - Run the nexus_cpuminer.exe file. For a description of the information shown in this application, please read this guide.
 
Hashing:
The GPU is a dedicated processing unit housed on-board your graphics card. The GPU is able to perform certain tasks extremely well, unlike your CPU, which is designed for parallel processing. Nexus supports both AMD and Nvidia GPU mining, and works best on the newer models. Officially, Nexus does not support GPU pool mining, but there are 3rd party miners with this capability.
The latest software for the Nvidia miner can be found here. The latest software for the AMD miner can be found here. The AMD miner is a third party miner. Information and advice about using the AMD miner can be found on our Slack channel. This guide will walk you through the Nvidia miner.
Step 1 - Close your wallet. Navigate to %appdata%\Nexus (~/Library/Application Support/Nexus on macOS) and open the nexus.conf file. Depending on your wallet, you may or may not have this file. If not, please create a new txt file and save it as nexus.conf
You will need to add the following lines before restarting your wallet:
Step 2 - Extract the files into a new folder.
Step 3 - Run the nexus.bat file. This will run the miner and deposit any rewards for mining a block into the account on your wallet.
For more information on either Prime Mining or Hashing, please join our Slack and visit the #mining channel. Additional information can be found here.
 
3. How do I stake Nexus?
Once you have your wallet installed, fully synchronized and encrypted, you can begin staking by:
After you begin staking, you will receive a Genesis transaction as your first staking reward. This establishes a Trust key in your wallet and stakes your wallet balance on that key. From that point, you will periodically receive additional Trust transactions as further staking rewards for as long as your Trust key remains active.
IMPORTANT - After you receive a Genesis transaction, backup your wallet.dat file immediately. You can select the Backup Wallet option from the File menu, or manually copy the file directly. If you do not do this, then your Nexus balance will be staked on the Trust key that you do not have backed up, and you risk loss if you were to suffer a hard drive failure or other similar problem. In the future, signature chains will make this precaution unnecessary.
 
4. I am staking with my Nexus balance. What are interest rate, trust weight, block weight, and stake weight?
These items affect the size and frequency of staking rewards after you receive your initial Genesis transaction. When staking is active, the wallet displays a clock icon in the bottom right corner. If you hover your mouse pointer over the icon, a tooltip-style display will open up, showing their current values.
Please remember to backup your wallet.dat file (see question 3 above) after you receive a Genesis transaction.
Interest Rate - The minting rate at which you will receive staking rewards, displayed as an annual percentage of your NXS balance. It starts at 0.5%, increasing to 3% after 12 months. The rate increase is not linear but slows over time. It takes several weeks to reach 1% and around 3 months to reach 2%.
With this rate, you can calculate the average amount of NXS you can expect to receive each day for staking.
Trust Weight - An indication of how much the network trusts your node. It starts at 5% and increases much more quickly than the minting (interest) rate, reaching 100% after one month. Your level of trust increases your stake weight (below), thus increasing your chances of receiving staking transactions. It becomes easier to maintain trust as this value increases.
Block Weight - Upon receipt of a Genesis transaction, this value will begin increasing slowly, reaching 100% after 24 hours. Every time you receive a staking transaction, the block weight resets. If your block weight reaches 100%, then your Trust key expires and everything resets (0.5% interest rate, 5% trust weight, waiting for a new Genesis transaction).
This 24-hour requirement will be replaced by a gradual decay in the Tritium release. As long as you receive a transaction before it decays completely, you will hold onto your key. This change addresses the potential of losing your trust key after months of staking simply because of one unlucky day receiving trust transactions.
Stake Weight - The higher your stake weight, the greater your chance of receiving a transaction. The exact value is a derived by a formula using your trust weight and block weight, which roughly equals the average of the two. Thus, each time you receive a transaction, your stake weight will reset to approximately half of your current level of trust.
