以前的genesis.json的文件差不多是這樣的：
{
"config": {
"chainId": 10,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"alloc" : {},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x00000002",
"extraData" : "",
"gasLimit" : "0x2fefd8",
"nonce" : "0x0000000000000042",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
}
用這個創世塊的描述文件初始化時，出現錯誤：
Fatal: Failed to write genesis block: unsupported fork ordering: eip150Block not enabled, but eip155Block enabled at 0
百度吧，沒有一個解決辦法。
后來用Puppeth命令創建json文件，并做了修改，如下所示：
{
"config": {
"chainId": 666,
"homesteadBlock": 0,
"eip150Block": 0,
"eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"eip155Block": 0,
"eip158Block": 0,
"byzantiumBlock": 0,
"constantinopleBlock": 0,
"petersburgBlock": 0,
"istanbulBlock": 0,
"ethash": {}
},
"nonce": "0x0",
"timestamp": "0x5ddf8f3e",
"extraData": "0x0000000000000000000000000000000000000000000000000000000000000000",
"gasLimit": "0x47b760",
"difficulty": "0x00002",
"mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"coinbase": "0x0000000000000000000000000000000000000000",
"alloc": { }
},
"number": "0x0",
"gasUsed": "0x0",
"parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
}
初始化：
geth --identity "MyEth" --rpc --rpcport "8545" --rpccorsdomain "*" --datadir gethdata --port "30303" --nodiscover --rpcapi "db,eth,net,personal,web3" --networkid 1999 init genesis.json
控制臺：
geth --identity "MyEth" --rpc --rpcport "8545" --rpccorsdomain "*" --datadir gethdata --port "30303" --nodiscover --rpcapi "db,eth,net,personal,web3" --networkid 1999 --dev.period 1 console
建立用戶：
>personal.newAccount();
挖礦：
miner.start();
終于順利挖到了人生第一桶金。
