在geth客户端部署智能合约

https://www.cnblogs.com/fengzhiwu/p/5629468.html 在geth上部署和调用智能合约完整教程在geth客户端部署智能合约1、编写智能合约源代码source="contract test { function multiply(uint a) returns(uint d) { return a * 7; } }";2、编译智能合约contract = eth.compile.solidity(source).test;这种方式需要在geth客户端安装solidity编译器solc，这个我暂时还没有找到解决办法，以后研究。我是用truffle客户端对智能合约进行编译的，编译之后，会生成一个合约对应的json文件。打开json文件，找到abi和bytecode在geth客户端进行定义。var abi=[{"constant": false,"inputs": [{"name": "a","type": "uint256"}],"name": "multiply","outputs": [{"name": "","type": "uint256"}],"payable": false,"stateMutability": "nonpayable","type": "function"}];var code="0x6060604052341561000f57600080fd5b60b18061001d6000396000f300606060405260043610603f576000357c0100000000000000000000000000000000000000000000000000000000900463ffffffff168063c6888fa1146044575b600080fd5b3415604e57600080fd5b606260048080359060200190919050506078565b6040518082815260200191505060405180910390f35b60006008820290509190505600a165627a7a72305820af1e3196bec2eb276a849a388e9c47ad20541b590c500c78c062d516b5b8de680029";3、创建智能合约对象MyContract=eth.contract(abi);4、部署合约。部署合约就是向以太坊上发送一个交易，目的地址不写就是发送给区块链contract=MyContract.new({from:eth.accounts[0],data:code});此时，可能会提示你账户不可用，就是没有解锁，用personal.unlockAccount()解锁即可，然后再部署部署完之后查看contract，发现address是undefined，这是因为交易才发送出去，没有矿工挖矿，没有写进区块链，所以还不知道。可以用txpool.status查看到5、启动挖矿miner.start();admin.sleepBlocks(13);miner.stop();挖矿之后，交易就写进区块链了，此时再查看contract就能看见有地址了。这样，智能合约就成功的部署在了以太坊上。
