coordinates mining operation.
- provide miners work with adjust difficulty and different SHA-256 coins (BTC/BCH)
- manage communicataion with miners according to stratum protocol
- communincate with bitcoind servers
- Redis
- connect-workers service (provide api to workers data)
- rabbit-mq (message broker - used for recording shares from miners)
npm i- Running rabbit-mq e.g.:
docker run -d --name rabbitmq --network="host" -e RABBITMQ_DEFAULT_VHOST=testnet -e RABBITMQ_DEFAULT_USER=guest -e RABBITMQ_DEFAULT_PASS=guest rabbitmq:3-management
- Running bitcoind server (e.g. BCH):
docker run --rm -it --name bitcoind zquestz/bitcoin-abc:0.18.2 bitcoind -rpcuser=test -rpcpassword=1234 -testnet
- Running redis:
docker run --name some-redis -d redis
This project can run using Docker, in order to run the project just from root project run:
docker build . -t coordinator
docker run --network="host" coordinator
or using node.js environment with:
npm start
coordinator uses winston as an underlying framework to handle logs
coordinator supports the following log messages:
- submit_new - sent whenever a new share received from one of the connected miners structure:
2018-04-17T09:31:17.138Z - info:
- type submit_new
- ip (ip | remote_ip - miner’s ip)
- create (timestamp | share created time)
- sId (string | session id)
- time (timestamp | share created time)
- nonce (string | share's nonce)
- ntime (timestamp | nonce timestamp)
- en1 (string | extra nonce 1)
- en2 (string | extra nonce 2)
- diff (integer | share's difficulty)
- wId (string | worker id)
- wName (string | worker name)
- uName (string | user name)
- hash (string | share's hash)
- tId (string | template id)
- height (integer | share's block height)
- jId (string | job id)
- coin (string | coin type e.g. btc\bch)
- cId (string | connection id)
- pId (string | process id)
- mId (string | machine id)
