以太坊私有链部署合约

以太坊私有链部署合约

1.建⽴私有链

[root@greg02~]#mkdirmychain

[root@greg02~]#cdmychain

[root@greg02mychain]#geth--networkid123--dev--datadirdata1--rpc--rpcaddr192.168.179.130--rpcport8989--port3000

#运⾏后产⽣如下⽂件

[root@greg02mychain]#ls

data1

[root@greg02mychain]#lsdata1/

store

各项含义：

--identity：指定节点ID；

--rpc：表⽰开启HTTP-RPC服务；

--rpcaddr：HTTP-RPC服务ip地址；

--rpcport：指定HTTP-RPC服务监听端⼝号（默认为8545）；

--datadir：指定区块链数据的存储位置；

--port：指定和其他节点连接所⽤的端⼝号（默认为30303）；

--nodiscover：关闭节点发现机制，防⽌加⼊有同样初始配置的陌⽣节点。

保持节点的运⾏，不要关闭终端，重新打开⼀个终端，使⽤gethattach连接节点，并且打开gethconsole

[root@greg02mychain]#gethattachipc:/root/mychain/data1/

作以太坊的JavaScript对象，可以直接使⽤这些对象。这些对象主要包括：

eth：包含⼀些跟操作区块链相关的⽅法；

net：包含⼀些查看p2p⽹络状态的⽅法；

admin：包含⼀些与管理节点相关的⽅法；

miner：包含启动&停⽌挖矿的⼀些⽅法；

personal：主要包含⼀些管理账户的⽅法；

txpool：包含⼀些查看交易内存池的⽅法；

web3：包含了以上对象，还包含⼀些单位换算的⽅法。

2.创建账户

>ount('grego')

>counts

3.编写只能合约

pragmasolidity^0.4.0;

contractBallot{

structVoter{

uintweight;

boolvoted;

uint8vote;

addressdelegate;

}

structProposal{

uintvoteCount;

}

addresschairperson;

mapping(address=>Voter)voters;

Proposal[]proposals;

///Createanewballotwith$(_numProposals)differentproposals.

functionBallot(uint8_numProposals)public{

chairperson=;

voters[chairperson].weight=1;

=_numProposals;

}

///Give$(toVoter)therighttovoteonthisballot.

///Mayonlybecalledby$(chairperson).

functiongiveRightToVote(addresstoVoter)public{

if(!=chairperson||voters[toVoter].voted)return;

voters[toVoter].weight=1;

}

///Delegateyourvotetothevoter$(to).

functiondelegate(addressto)public{

Voterstoragender=voters[];//assignsreference

if()return;

while(voters[to].delegate!=address(0)&&voters[to].delegate!=)

to=voters[to].delegate;

if(to==)return;

=true;

te=to;

VoterstoragedelegateTo=voters[to];

if()

proposals[].voteCount+=;

el

+=;

}

///Giveasinglevotetoproposal$(toProposal).

functionvote(uint8toProposal)public{

Voterstoragender=voters[];

if(||toProposal>=)return;

=true;

=toProposal;

proposals[toProposal].voteCount+=;

proposals[toProposal].voteCount+=;

}

functionwinningProposal()publicconstantreturns(uint8_winningProposal){

uint256winningVoteCount=0;

for(uint8prop=0;prop<;prop++)

if(proposals[prop].voteCount>winningVoteCount){

winningVoteCount=proposals[prop].voteCount;

_winningProposal=prop;

}

}

}

ABI删除空格并转义

[{"constant":fal,"inputs":[{"name":"to","type":"address"}],"name":"delegate","outputs":[],"payable":fal,"stateMutability":"nonpayable","type

在console⾥创建ABI合约对象
