Messages from the Mines backend code

This repo contains Node.js server-side code for Messages from the Mines. It does the following:

• Serves the front-end from mftm-frontend (Not yet)
• Exposes the mftm-database MySQL database as a web API (see https://localhost:8989/example-frontend).
• Launches the Bitcoin Core node via start_bitcoind.sh.
• Communicates with bitcoind daemon via JSONRPC.
• Serves an admin data review CMS at https://localhost:8989/review

Installing Dependencies

# install the ZeroMQ development files
sudo apt-get update
sudo apt-get install libzmq3-dev

# install the npm modules
npm install

Generate SSL key pair

For security reasons, we haven't included keys in the ssl/ folder. Create some once you've cloned:

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout ssl/private.key -out ssl/certificate.crt

Edit credentials in config.json and bitcoin.conf

config.json comes with dummy values for: - Basic authentication user/pass - MySQL user/pass - bitcoind JSONRPC user/pass

Edit basicAuth.users, mysql.user, mysql.password, bitcoinRPCClient.user, and bitcoinRPCClient.pass.

	}
}

bitcoin.conf contains dummy values for rpcuser and rpcpassword as well. Change those too.

rpcuser=admin
rpcpassword=change-me-or-get-pwned

Start the bitcoind Daemon

Bitcoin Core must be running for server.js to work properly. Before running, change -datadir to point to your Bitcoin Core data folder (usually ~/.bitcoin) in start_bitcoind.sh.

# change -datadir directory and save the file
nano start_bitcoind.sh

# start the bitcoind server
./start_bitcoin.sh

Launch the Server

Once bitcoind is running, launch the node server:

node server
