Square building private Ethernet network

Create a directory and profile creation block

Creation block the establishment of profiles genesis.json, enter the following:

{
  "nonce": "0x0000000000000042",
  "timestamp": "0x0",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "extraData": "0x00",
  "gasLimit": "0x80000000",
  "difficulty": "0x1",
  "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x3333333333333333333333333333333333333333",
  "alloc": {     },
    "config":{
      "chainId":15,
      "homesteadBlock":0,
      "eip155Block":0,
      "eip158Block":0
  }
}

Creation create blocks in genesis.json directory, enter the command line

geth --datadir ethereum init genesis.json

 Ethereum will automatically generate a folder, there are two folders geth and keystore

 

 

Geth into the console

Command line input geth --datadir ethereum --nodiscover --dev.period 1 console 

Geth command

Chinese version of the console [command options] [argument ...]

Here will be successful

New command line, enter account

personal.newAccount ( "12345") code is 12345, account files are stored in keystore
