Metaforce佛萨奇智能合约矩阵构建佛萨奇是一个基于区块链的智能合约矩阵,合约还定义了一个映射voters,用于存储每个地址对应的选民状态,并定义了一个数组proposals,用于存储所有提案的状态。
如何使用一个简单的去中心化应用程序,并提供代码示例?
require(sender.voted == false, "Already voted.");
name: proposalNames[i],
voteCount: 0
}));
}
} function giveRightToVote(address voter) public {
require(
msg.sender == chairperson,
chairperson = msg.sender;
voters[chairperson].authorized = true;
for (uint i = 0; i < proposalNames.length; i++) {
proposals.push(Proposal({
sender.voted = true;
sender.vote = proposal;
"Only chairperson can give right to vote."
);
require(
!voters[voter].voted,
"The voter already voted."
);
require(voters[voter].authorized == false, "The voter is already authorized.");
voters[voter].authorized = true;
}
function vote(uint proposal) public {
Voter memory sender = voters[msg.sender];
require(sender.authorized == true, "You are not authorized to vote.");
if (proposals[i].voteCount > winningVoteCount) {
winningVoteCount = proposals[i].voteCount;
winningProposal_ = i;
}
csharpCopy codepragma solidity ^0.8.0;
contract Voting {
struct Voter {
bool authorized;
bool voted;
uint vote;
}
struct Proposal {
string name;
uint voteCount;
}
address public chairperson;
mapping(address => Voter) public voters;
Proposal[] public proposals;
constructor(string[] memory proposalNames) {
proposals[proposal].voteCount += 1;
}
function winningProposal() public view returns (uint winningProposal_) {
uint winningVoteCount = 0;
for (uint i = 0; i < proposals.length; i++) {
}
}
}
}
旨在提供一个开放、安全、高效的智能合约开发平台。提供了一种可靠的、去中心化的方法来存储和执行智能合约。
