区块链游戏质押挖矿系统开发规则源码解析

区块链游戏质押挖矿通常采用区块链上的智能合约来实现。智能合约是一种自动执行的代码，可以在满足一定条件时执行预定义的操作。在区块链游戏中，智能合约可以用来管理游戏内的数字资产、经济模型和游戏规则等。

其次，质押挖矿通常采用权益证明（POS）或委托权益证明（DOPS）等共识机制。这些机制允许玩家通过质押数字货币来获得验证权和记账权，从而获得游戏内资产。在POS或DPOS机制下，验证者或代表需要质押一定数量的数字货币以获得验证权或代表权。

constructor(address _rewardUNITokens,address _stakingLPTokens,uint _stakingTime){
    rewardUNITokens = rewardTokens(_rewardUNITokens);
    stakingLPTokens = LPToken(_stakingLPTokens);
    stakingTime = _stakingTime;
}
modifier update(address owner) {
    lastUpdateTime = getLastTime();
    rewardPerTokenStored = rewardUNIPerToken();
    if(owner != address(0)){
        userRewardsPerToken[owner] = rewardPerTokenStored;
        rewards[owner] = allRewardsOfUser(owner);
    }

       rewardUNI = rewardPerTokenStored;
   }
   rewardUNI = rewardPerTokenStored.add(getLastTime().sub(lastUpdateTime).mul(rewardRate).mul(1e18).div(_totalSupply));
