区块链实战(3):用Solidity实现投票智能合约
在以太坊区块链上,Solidity是一种流行的、用于编写智能合约的语言,尤其适用于去中心化金融(DeFi)应用。分账合约,也称为分配合同或分红合约,是一种常见的智能合约设计,用于自动按照预设的比例将代币分配给参与者。
Solidity代码示例(简化版):
```solidity
pragma solidity ^0.8.0;
contract TokenDistributor {
address public owner;
mapping(address => uint) public balances;
constructor() {
owner = msg.sender; // 合约创建者默认拥有所有权利
}
function distributeTokens(uint _amount, address[] memory _receivers, uint256 _ratios[]) public {
require(msg.sender == owner, "Only the contract owner can distribute tokens.");
for (uint i = 0; i < _receivers.length; i++) {
require(_receivers[i] != address(0), "Invalid receiver address.");
balances[_receivers[i]] += (_amount * _ratios[i]) / 1e18; // 转换比例为小数
}
}
function withdrawTokens(address _receiver) public {
require(balances[_receiver] > 0, "No balance to withdraw.");
payable(_receiver).transfer(balances[_receiver]);
balances[_receiver] = 0; // 更新余额防止重复提取
}
}
```
这个合约定义了一个`TokenDistributor`,允许合约所有者分配代币给指定地址并按比例分配。`withdrawTokens`函数则允许接收者取回他们的份额。
