Installing BitcoinSv Server

I found some tutorials and I'm putting together a Bitcoin Scripting Language Hackathon for our local Linux Users group webinar and am having a hard time getting a server to work properly. It's been a number of years since the last time I ran a server and I tried downloading this https://download.bitcoinsv.io/bitcoinsv/0.2.2.beta/. According to the readme it says to just run the command bin/bitcoind but it errors with "bitcoind not found" and the bin/bitcoind file is a copy of the readme. It's not a real install. Then I looked at the Github repository at https://github.com/bitcoin-sv/bitcoin-sv/blob/mastedoc/build-unix.md. I don't know how many of our users will be able to build it that way and, looking at the instructions, they are a bit sparse.
Anyway, two questions: 1) are there any better sources to help get a Bitcoin server going? and 2) Are there any scripting language tutorials based on BitcoinSV? All the ones I found were using BTC but I'm thinking it won't matter that much for a beginner's tutorial (but any help to shed a light on that would be great).

(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.

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.

Nervos CKB Testnet Mining Competition

The Nervos Common Knowledge Base (CKB) is a preservation focused, “Store of Assets” public permissionless blockchain and the base layer of the Nervos network. Nervos generalizes Bitcoin’s UTXO model, creating a ‘cell model’ that supports smart contracts and Layer 2 protocols with a RISC-V virtual machine.
Check out the Nervos CKB in a Nutshell article!: https://medium.com/nervosnetwork/nervos-ckb-in-a-nutshell-7a4ac8f99e0e

Nervos CKB Testnet Mining Competition - https://mineyourownbusiness.nervos.org/
To provide the community increased opportunities for involvement in the construction of Nervos CKB, the Nervos Foundation has officially decided to sponsor and host the Nervos CKB testnet mining competition. Anyone (outside of U.S. citizens unfortunately 😬) can participate in the event by mining testnet tokens and compete for a total prize of 1 million mainnet CKB tokens.
Reward One: Mining Whale AwardsBlock rewards produced by each address will be ranked. Upon the completion of competition, the top three addresses that have mined the highest amount of block rewards will be rewarded as follows:
First place: 200,000 CKB TokensSecond place: 100,000 CKB TokensThird place: 60,000 CKB Tokens
Reward Two: LotteryAt the end of competition, 64 addresses will be randomly selected from addresses that have produced blocks (with the top three addresses excluded) and will be given 10,000 CKB tokens as rewards.
Lottery Rules:We will release the code base for lottery drawing ahead of time and use the block hash of the block at Nth block height as the seed for random number generation for selecting the lucky addresses.
We will announce a hash at the same time; the hash’s preimage will include information about N.
Participants will be able to use announced hash and lottery code to verify the outcome of the lottery.
DatesStart Time: Saturday, June 15, 2019 6:00:00 AM UTC, UNIX Timestamp: 1560578400At this time, participants can download the latest version of CKB client (v0.14.0) from GitHub releases https://github.com/nervosnetwork/ckb/releases, start a node, join the testnet and start mining.
End Time: Saturday, June 29, 2019 6:00:00 AM UTC, UNIX Timestamp: 1561788000Based on the UNIX timestamp of the block, the competition will end and the block reward rankings will be calculated.
How to ParticipateTo start mining on CKB testnet, simply follow the steps outlined in the official guide https://docs.nervos.org/ or community-created tutorials https://talk.nervos.org/. A CKB blockchain browser https://explorer.nervos.org/ is available to check mining rewards.
Upon the completion of competition, we will calculate block rewards mined by each address. The accumulated block reward of each address during the competition will be the basis for determining the competition's winning miners and recipients of CKB mainnet token prizes (testnet tokens gained by transactions will NOT be counted as block rewards).
Rewards will be distributed directly to respective addresses on CKB mainnet. Hence, please exercise caution when managing your private key as it will be your sole means of claiming your CKB mainnet token rewards.

BFGMiner Garlicoin tutorial

Some people have been having trouble with BFGMiner for Garlicoin, so I made a tutorial. This will only work on a Unix-based shell.
I have been informed that the Pastebin may not be beginner-friendly, so I will help anyone who needs it.
Thanks to ChilledGrease for their help with making the tutorial.
  1. Download and extract http://www.digip.org/jansson/releases/jansson-2.10.tar.gz
  2. cd to the folder and run ./configure && make && make install
  3. Download and extract https://github.com/troydhanson/uthash/archive/master.zip
  4. Download and extract http://luke.dashjr.org/programs/bitcoin/files/bfgmine4.10.6/bfgminer-4.10.6.zip
  5. cd to the bfgminer folder and run env CFLAGS='-I../uthash-mastesrc' ./configure --enable-opencl --enable-scrypt --enable-cpumining, assuming uthash-master is the directory you extracted in part 3.
  6. Run make && make install. If it says you do not have permission to do something, run sudo make install and enter your password.
  7. Set up garlicoind and its config. There is a tutorial here.
  8. Run garlicoind.
  9. Run this command: bfgminer --scrypt -o localhost:42070 -u [username in garlicoind config] -p [password] --no-longpoll --no-stratum --coinbase-addr [your address] -S opencl:auto

Edit: Adding citations section as well as CPU mining for those of you who don't want to or can't use a GPU.
Edit 2: Clarifications
Edit 3: Removed CPU mining as I cannot currently get it to work.
Edit 4: I don't want to make a 100000 character long post so I'm not gonna put this anymore.
Edit again: I can't get BFGMiner to work with the new scrypt:2048 algorithm, so this will not work for the time being.

[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)
Tip if you want : 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v
updated 03/12 - will update more, soon.
updated 03/12.2 - I updated the whole process a bit and also added some improvements.
updated 03/14/ Added a tl;dr version at the end.

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 :) )

Nervos CKB Testnet Mining Competition

The Nervos Common Knowledge Base (CKB) is a preservation focused, “Store of Assets” public permissionless blockchain and the base layer of the Nervos network. Nervos generalizes Bitcoin’s UTXO model, creating a ‘cell model’ that supports smart contracts and Layer 2 protocols with a RISC-V virtual machine.
Check out the Nervos CKB in a Nutshell article!: https://medium.com/nervosnetwork/nervos-ckb-in-a-nutshell-7a4ac8f99e0e
Nervos CKB Testnet Mining Competition - https://mineyourownbusiness.nervos.org/ To provide the community increased opportunities for involvement in the construction of Nervos CKB, the Nervos Foundation has officially decided to sponsor and host the Nervos CKB testnet mining competition. Anyone (outside of U.S. citizens unfortunately 😬) can participate in the event by mining testnet tokens and compete for a total prize of 1 million mainnet CKB tokens.
Reward One: Mining Whale Awards Block rewards produced by each address will be ranked. Upon the completion of competition, the top three addresses that have mined the highest amount of block rewards will be rewarded as follows:
First place: 200,000 CKB Tokens Second place: 100,000 CKB Tokens Third place: 60,000 CKB Tokens
Reward Two: Lottery At the end of competition, 64 addresses will be randomly selected from addresses that have produced blocks (with the top three addresses excluded) and will be given 10,000 CKB tokens as rewards.
Lottery Rules: We will release the code base for lottery drawing ahead of time and use the block hash of the block at Nth block height as the seed for random number generation for selecting the lucky addresses.
We will announce a hash at the same time; the hash’s preimage will include information about N.
Participants will be able to use announced hash and lottery code to verify the outcome of the lottery.
Dates Start Time: Saturday, June 15, 2019 6:00:00 AM UTC, UNIX Timestamp: 1560578400 At this time, participants can download the latest version of CKB client (v0.14.0) from GitHub releases https://github.com/nervosnetwork/ckb/releases, start a node, join the testnet and start mining.
End Time: Saturday, June 29, 2019 6:00:00 AM UTC, UNIX Timestamp: 1561788000 Based on the UNIX timestamp of the block, the competition will end and the block reward rankings will be calculated.
How to Participate To start mining on CKB testnet, simply follow the steps outlined in the official guide https://docs.nervos.org/ or community-created tutorials https://talk.nervos.org/. A CKB blockchain browser https://explorer.nervos.org/ is available to check mining rewards.
Upon the completion of competition, we will calculate block rewards mined by each address. The accumulated block reward of each address during the competition will be the basis for determining the competition's winning miners and recipients of CKB mainnet token prizes (testnet tokens gained by transactions will NOT be counted as block rewards).
Rewards will be distributed directly to respective addresses on CKB mainnet. Hence, please exercise caution when managing your private key as it will be your sole means of claiming your CKB mainnet token rewards.

Reward Two: Lottery At the end of competition, 64 addresses will be randomly selected from addresses that have produced blocks (with the top three addresses excluded) and will be given 10,000 CKB tokens as rewards.
Lottery Rules: We will release the code base for lottery drawing ahead of time and use the block hash of the block at Nth block height as the seed for random number generation for selecting the lucky addresses.
We will announce a hash at the same time; the hash’s preimage will include information about N.
Participants will be able to use announced hash and lottery code to verify the outcome of the lottery.
Dates Start Time: Saturday, June 15, 2019 6:00:00 AM UTC, UNIX Timestamp: 1560578400 At this time, participants can download the latest version of CKB client (v0.14.0) from GitHub releases https://github.com/nervosnetwork/ckb/releases, start a node, join the testnet and start mining.
End Time: Saturday, June 29, 2019 6:00:00 AM UTC, UNIX Timestamp: 1561788000 Based on the UNIX timestamp of the block, the competition will end and the block reward rankings will be calculated.
How to Participate To start mining on CKB testnet, simply follow the steps outlined in the official guide https://docs.nervos.org/ or community-created tutorials https://talk.nervos.org/. A CKB blockchain browser https://explorer.nervos.org/ is available to check mining rewards.
Upon the completion of competition, we will calculate block rewards mined by each address. The accumulated block reward of each address during the competition will be the basis for determining the competition's winning miners and recipients of CKB mainnet token prizes (testnet tokens gained by transactions will NOT be counted as block rewards).
Rewards will be distributed directly to respective addresses on CKB mainnet. Hence, please exercise caution when managing your private key as it will be your sole means of claiming your CKB mainnet token rewards.
