ethereum搭建问题解决

创建创世区块文件->初始化区块->启动节点

一、初始化节点报错Fatal: Failed to write genesis block: unsupported fork ordering: eip150Block not enabled, but eip155Block enabled at 0 genesis block

解决方法:

在genesis.json文件中添加 eip150Block字段信息。全文更新后如下:

{
  "config": {
        "chainId": 20210311,
        "homesteadBlock": 0,
    "eip150Block": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc"      : {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
  "difficulty" : "0x20000",
  "extraData"  : "",
  "gasLimit"   : "0x2fefd8",
  "nonce"      : "0x0000000000000042",
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "timestamp"  : "0x00"
}

二、对等节点发现问题:

先使用admin.nodeInfo查询需要连接节点到信息,如:

{
  enode: "enode://fb161d7fd7cdce3fc0ddefb9a54c84ccd128aa8f6e0adfab157557f778e0305256f330e5ed8d423a354bcab8fff4cc04635a6c1bad45f796cc68e11aeb1997de@119.123.132.69:30303?discport=65158",
  enr: "enr:-J-4QIrKejUxOYUS5-afohUOn4m9W8Xp535guMxGxvBd7AelL8pEXrnrYGrtnu5-UngNRbWwuzQBQyE9uiW2dKdU7g8Eg2V0aMfGhHEB0w2AgmlkgnY0gmlwhHd7hEWJc2VjcDI1NmsxoQL7Fh1_183OP8Dd77mlTITM0Siqj24K36sVdVf3eOAwUoN0Y3CCdl-DdWRwgv6GhHVkcDaCdl8",
  id: "daa0fcd9bda92ac86222ba00232db20b4642cd6e376489707ec6dbcb20321fea",
  ip: "119.123.132.69",
  listenAddr: "[::]:30303",
  name: "Geth/v1.9.6-stable-bd059680/windows-amd64/go1.13",
  ports: {
    discovery: 65158,
    listener: 30303
  },
  protocols: {
    eth: {
      config: {
        chainId: 20210312,
        eip150Block: 0,
        eip150Hash: "0x0000000000000000000000000000000000000000000000000000000000000000",
        eip155Block: 0,
        eip158Block: 0,
        homesteadBlock: 0
      },
      difficulty: 17419421,
      genesis: "0x5e1fc79cb4ffa4739177b5408045cd5d51c6cf766133f23f7cd72ee1f8d790e0",
      head: "0xf32af07450d30f5472346288c244f6b50148e0351d3386426fb10d09cac2dc8f",
      network: 20210312
    }
  }
}

然后执行

admin.addPeer("enode://fb161d7fd7cdce3fc0ddefb9a54c84ccd128aa8f6e0adfab157557f778e0305256f330e5ed8d423a354bcab8fff4cc04635a6c1bad45f796cc68e11aeb1997de@119.123.132.69:30303?discport=65158")

括号内的内容即为上面查询到的enode信息。
