开创以太坊私有链

1.编写json文件

{

  "config": {

        "chainId": 15,

        "homesteadBlock": 0,

        "eip155Block": 0,

        "eip158Block": 0

    },

    "coinbase" : "0x0000000000000000000000000000000000000000",

    "difficulty" : "0x40000",

    "extraData" : "",

    "gasLimit" : "0xffffffff",

    "nonce" : "0x0000000000000042",

    "mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",

    "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",

    "timestamp" : "0x00",

    "alloc": { }

}

2.使用命令

geth init ./adam.json --datadir "./chain"

运行结果
