1. 合约源码

pragma solidity ^0.4.24;

contract MultipleSignature{
    address private owner;
    uint256 public signEnd;    
    uint public passRates;
    uint private transactionNum;
    uint public managerCount=1;

    modifier isOwner{
        require(owner == msg.sender);
        _;
    }

    modifier isManager{
        require(now < signEnd);
        require(msg.sender == owner || managers[msg.sender] == 1); 
        _;
    }    

    struct Transaction {
        address from;
        address to;
        uint amount;
        uint signatureCount;
        mapping (address => uint8) signatures;
    }

    mapping(address => uint8) private managers;
    mapping (uint => Transaction) privat
