Ou gerar ficheiro utilizando puppeth.

Iniciar nó

$ geth init genesis.json --datadir db_1
$ geth --networkid 5777 --rpc --rpcport 8545 --rpccorsdomain "*" --datadir db_1 console
() > personal.newAccount()

Segundo:

$ geth init genesis.json --datadir db_2
$ geth --networkid 5777 --rpc --rpcport 7545 --rpccorsdomain "*" --port 30304 --datadir db_2 console
# obter peer enode do primeiro nó com comando admin
# copiar enode
() > admin.addPeer(enode-do-primeiro-nó)

Minar

# tem de existir uma conta base, criada através de personal.newAccount()
() > miner.start()
# para parar
() > miner.stop()

Block Explorer

$ docker run -p 80:80 -e APP_NODE_URL="http://localhost:8545" alethio/ethereum-lite-explorer
