goBlockchainDataAnalysis

blockchain data analysis, written in Go

Not finished - ToDo list

• Backend
  • Network Address generation avoiding infinite relation loops
  • Sankey Address generation without loops
• Frontend
  • After Sankey visualization, go to Network Address visualization and render without Sankey dots
• Both
  • Tx/day
  • Tx volume
  • Block size
  • Blockchain size

Install

1. Nodejs & NPM https://nodejs.org/ --> to get npm packages for the web
2. MongoDB https://www.mongodb.com/
3. Faircoin wallet https://download.faircoin.world/, or the Cryptocurrency desired wallet
4. goBlockchainDataAnalysis https://github.com/arnaucode/goBlockchainDataAnalysis

Configure

• Wallet /home/user/.faircoin2/faircoin.conf:

rpcuser=usernamerpc
rpcpassword=password
rpcport=3021
rpcworkqueue=2000
server=1
rpcbind=127.0.0.1
rpcallowip=127.0.0.1

• goBlockchainDataAnalysis/config.json:

{
    "user": "usernamerpc",
    "pass": "password",
    "host": "127.0.0.1",
    "port": "3021",
    "genesisTx": "7c27ade2c28e67ed3077f8f77b8ea6d36d4f5eba04c099be3c9faa9a4a04c046",
    "genesisBlock": "beed44fa5e96150d95d56ebd5d2625781825a9407a5215dd7eda723373a0a1d7"
}

Run

1. Start MongoDB

sudo service mongod start

2. Start wallet

./faircoind -txindex -reindex-chainstate

Wait until the entire blockchain is downloaded.

3. Run explorer, to fill the database

./goBlockchainDataAnalysis -explore

3.1. The next runs, once the database have data, can just run:

./goBlockchainDataAnalysis

Webapp will run on 127.0.0.1:8080

4. ADDITIONAL - Run the webserver, directly from the /web directory This can be useful if need to deploy the API server in one machine and the webserver in other. In the /web directory:

npm start

Webapp will run on 127.0.0.1:8080
