Geth如何保持区块链状态？

Question

Fedora 27、CentOS 1708、Go-ethereum 1.8.1

我正在尝试用它来制作私有区块链和硬币。

Genesis.json:

{
  "config": {
        "chainId": 42,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc": {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
  "difficulty" : "0x1000000",
  "extraData"  : "",
  "gasLimit"   : "0x2fefd8",
  "nonce"      : "0x0000000012345678",
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "timestamp"  : "0x00"
}

我运行在控制台中使用：

geth init genesis.json --datadir datadir
geth console --rpc --rpcport "8080" --rpccorsdomain "*" --datadir "datadir" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --networkid 7296

然后我注册了新账号开始挖矿。有用。但是当我重新启动geth时，区块链状态似乎没有保存。

如何解决？退出geth后还能保持区块链状态吗？

Answer 1

可能是当前版本中的错误... 使用选项 --gcmode "archive"
