windows下搭建cpp-ethereum私有链

 1.在编译出来的aleth.exe目录下创建一个创世块文件genesis.json：

{ 
 	"sealEngine": "Ethash", 
 	"params": { 
 		"accountStartNonce": "0x00", 
 		"maximumExtraDataSize": "0x20", 
 		"homesteadForkBlock": "0x00", 
 		"EIP150ForkBlock": "0x00", 
 		"EIP158ForkBlock": "0x00", 
 		"byzantiumForkBlock": "0x00", 
 		"constantinopleForkBlock": "0x00", 
 		"minGasLimit": "0x1388", 
 		"maxGasLimit": "7fffffffffffffff", 
 		"tieBreakingGas": false, 
 		"gasLimitBoundDivisor": "0x0400", 
 		"minimumDifficulty": "0x020000", 
 		"difficultyBoundDivisor": "0x0800", 
 		"durationLimit": "0x0d", 
 		"blockReward": "0x4563918244F40000", 
 		"networkID" : "0x454", 
 		"chainID": "0x01", 
 		"allowFutureBlocks" : true 
 	}, 
 	"genesis": { 
 		"nonce": "0x0000000000000042", 
 		"difficulty": "0x400000000", 
 		"mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000", 
 		"author": "0x0000000000000000000000000000000000000000", 
 		"timestamp": "0x00", 
 		"parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000", 
 		"extraData": "0x11bbe8db4e347b4e8c937c1c8370e4b5ed33adb3db69cbdb7a38e1e50b1b82fa", 
 		"gasLimit": "0x1388" 
 	}, 
 	"accounts": { 
 		"0000000000000000000000000000000000000001": { "precompiled": { "name": "ecrecover", "linear": { "base": 3000, "word": 0 } } }, 
 		"0000000000000000000000000000000000000002": { "precompiled": { "name": "sha256", "linear": { "base": 60, "word": 12 } } }, 
 		"0000000000000000000000000000000000000003": { "precompiled": { "name": "ripemd160", "linear": { "base": 600, "word": 120 } } }, 
 		"0000000000000000000000000000000000000004": { "precompiled": { "name": "identity", "linear": { "base": 15, "word": 3 } } }, 
 		"0000000000000000000000000000000000000005": { "precompiled": { "name": "modexp" } }, 
 		"0000000000000000000000000000000000000006": { "precompiled": { "name": "alt_bn128_G1_add", "linear": { "base": 500, "word": 0 } } }, 
 		"0000000000000000000000000000000000000007": { "precompiled": { "name": "alt_bn128_G1_mul", "linear": { "base": 40000, "word": 0 } } }, 
 		"0000000000000000000000000000000000000008": { "precompiled": { "name": "alt_bn128_pairing_product" } } 
 	} 
 } 

2.打开cmd，进入aleth.exe目录，输入命令行开始挖矿：

aleth --config genesis.json -m on -v 5 --network-id 1108 --ipc --listen 30307 --port 30307 --db-path blockchain --private "mynet"

3.打开ethconsole进行连接，得到一个web3对象，然后就可以通过web3这个对象来操作了，关于web3的api可以参考http://web3js.readthedocs.io/en/1.0/index.html
