创建新账号

personal.newAccount()

或者 personal.newAccount("123456")

 

查看节点信息

admin.nodeInfo

 

挖矿

开始挖矿 miner.start(1)

停止挖矿 miner.stop()

 

查看当前矿工账号

eth.coinbase 默认为第一个账户

 

修改矿工账号

miner.setEtherbase(eth.accounts[1])

 

查看账户信息

eth.accounts[0]

 

查看账户余额

eth.getBalance(eth.accounts[0])

或者 web3.fromWei(eth.getBalance(eth.accounts[0]), "ether")

 

解锁账号

personal.unlockAccount(eth.accounts[0])

使用账户资金前都需要先解锁账号

 

转账eth.sendTransaction({from:eth.accounts[0],to:"0x587e57a516730381958f86703b1f8e970ff445d9",value:web3.toWei(3,"ether")})

使用 txpool.status 可以看到交易状态

 

查看区块数据

eth.blockNumber

eth.getTransaction("0x0c59f431068937cbe9e230483bc79f59bd7146edc8ff5ec37fea6710adcab825")

eth.getBlock(1) 通过区块号查看区块
