1.新建目录及创世文件
#私有链数据存储目录
mkdir -p /Users/mac/software/blockchain/ethereum/private_chain/PrivateChain
cd /Users/mac/software/blockchain/ethereum/private_chain
touch genesis.json
vi genesis.json
加入下面内容
{
"coinbase": "0x0000000000000000000000000000000000000000",
"config": {
"homesteadBlock": 5
},
"difficulty": "0x20000",
"extraData": "0x",
"gasLimit": "0x2FEFD8",
"mixhash": "0x00000000000000000000000000000000000000647572616c65787365646c6578",
"nonce": "0x0",
"parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp": "0x00",
"alloc": {
"dbdbdb2cbd23b783741e8d7fcf51e459b497e4a6":
{
"balance":"100000000000000000000000000000"
}
}
}
2.启动geth，初始化创世文件
geth --datadir /Users/mac/software/blockchain/ethereum/private_chain/PrivateChain init /Users/mac/software/blockchain/ethereum/private_chain/genesis.json
3.启动eth控制台
geth --datadir /Users/mac/software/blockchain/ethereum/private_chain/PrivateChain console
4.创建账户，挖矿
personal.newAccount()
Passphrase:
Repeat passphrase:
"0x63c2d7bcff151c9f8821602425c99aeb55827c49"
my = eth.accounts[0]
eth.getBalance(my)
miner.start()
过一段时间后停止挖矿，并查看账户余额
miner.stop()
eth.getBalance(my)
5.转账
personal.newAccount('123')
"0xc32fb24dc8c62ddde9e9389b4d9abb0415faf73b"
eth.getBalance(eth.accounts[1])
other=eth.accounts[1]
首先解锁被转移账号
personal.unlockAccount(my)
Unlock account 0x63c2d7bcff151c9f8821602425c99aeb55827c49
Passphrase:
true
创建交易
eth.sendTransaction({from:my,to:other,value:1})
INFO [04-07|10:43:00] Submitted transaction fullhash=0x1c74e91304324b721a906a67ed337cd90850ddcba13bfd00bdda6a86999b8539 recipient=0xc32FB24dC8c62dDDE9e9389B4D9AbB0415faf73b
"0x1c74e91304324b721a906a67ed337cd90850ddcba13bfd00bdda6a86999b8539"
> eth.getBalance(my)
245000000000000000000
> eth.getBalance(other)
0
此时还是0，因为需要挖矿,查看余额
miner.start()
miner.stop()
eth.getBalance(other)
1
