Q. What is Bitcoin ?

Ans: Bitcoin is digital currency in which encryption techniques are used to regulate the generation of units of currency. In 2009 by an unknown person using the alias Satoshi Nakamoto.

OS: Ubuntu Server 14.04 LTS
Minimum HDD Size: 120 GB
Minimum RAM:  3.5 GB
CPU: 2 Cores

Step: 1. Install Prerequisites :

# apt-get update
# apt-get -y install python-software-properties
# apt-get -y install build-essential libboost-all-dev automake libtool autoconf
# apt-get -y install libdb++-dev
# apt-get -y install libboost-all-dev
# apt-get -y install pkg-config
# apt-get -y install libssl-dev
# apt-get -y install libcurl4-openssl-dev
# apt-get -y install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler
# apt-get -y install git

Step: 2. Install BitcoinXT :

# cd
# git clone https://github.com/bitcoinxt/bitcoinxt
# cd bitcoinxt
# ./autogen.sh
# ./configure --with-cli=yes --with-gui=no --disable-wallet
# make
# make install

Step: 3. We will Run bitcoind once so it Generates the proper Directories :

# bitcoind -server

Step: 4. Configure BitcoinXT :

# echo 'rpcuser=bitcoinrpc' > ~/.bitcoin/bitcoin.conf   (Default Bitcoin XT User)
# echo 'rpcpassword=6Q9k65HhrgA1ghY1chr2x4776AwEkkf1eH5eZ7Fh7dXk' >>  ~/.bitcoin/bitcoin.conf  (Default Bitcoin XT Password)
# echo 'server=1' >>  ~/.bitcoin/bitcoin.conf

Step: 5. Verify config-file Values are in the file :

# cat ~/.bitcoin/bitcoin.conf

Step: 6. To Check this has Worked perform the Following :

# cd ~/.bitcoin
# ls -al

"blocks" should be in a cyan colour and look like this: blocks -> /media/data/blocks Node that it's the current user, bitcoin, that has file access.

Step: 7. The Daemon should now be ready to Start :

# bitcoind -daemon

Step: 8. Type the Following to run a Small Test :

# bitcoin-cli getinfo

The output should be something like this :

{
    "version" : 110000,
    "protocolversion" : 70010,
    "blocks" : 90012,
    "timeoffset" : -1,
    "connections" : 8,
    "proxy" : "",
    "difficulty" : 3091.73689041,
    "testnet" : false,
    "relayfee" : 0.00001000,
    "errors" : ""
}

Step: 9. Also, go to https://getaddr.bitnodes.io/ & type in the node network address. ex: 192.168.72.10 & click "CHECK NODE".

Something like the following should show to verify you are running BitcoinXT:

192.168.72.10:8333 /Bitcoin XT:0.11.0/

Step: 10. To Check Block Chain :

https://blockchain.info/

# bitcoin-cli getblockcount

Step: 11. To Check BitcoinXT Version :

# bitcoind -version

Bitcoin XT Daemon version v0.11.0.0-fa6040a
Copyright (C) 2009-2015 The Bitcoin XT Developers

Step: 12. To Check Debug Log files :

# tail -100f ~/.bitcoin/debug.log
