Usage

Setup Miners

Prepare storage folder and keypair

mkdir .bbc_storage  # the folder to store blockchain data
mkdir conf # the folder to store configurations
go run wallet/wallet.go genkey > conf/miner1.json # generate a key pair for the node

Set up a server listening on 30001 port, it broadcast its own address as miner1.example.com:30001, and connect to peers at miner2.example.com:30001 and miner3.example3.com:30001. The miner will store the mining reward in the address corresponding to the keypair in conf/miner1.json.

go run server/server.go --key conf/miner1.json \
  -l 0.0.0.0:30001 \
  -a miner1.example.com:30001 \
  -p miner2.example.com:30001 \
  -p miner3.example.com:30001

Run go run tester/server.go -h for other available options.
