摘　　要：针对使用哈希时间锁定算法进行跨链资产交换的过程中,网络攻击者可在极短的时间内创建大量交易且不完成交易过程,利用时间锁引起大量的交易超时,使得区块链网络中存在大量垃圾交易信息,阻塞区块链网络的问题,提出了一种基于用户信誉改进时间锁的哈希时间锁定算法。该方法引入交易保证金机制,通过用户节点信誉积分控制其在创建跨链交易时能设置的时间锁长度。该算法能快速释放时间锁超时的交易,降低节点作恶时对区块链网络造成的影响。此外,还设置了交易保证金机制,进一步增加了节点作恶的成本,以保证跨链交易的正常进行。A hash time lock algorithm based on user reputation improvement is proposed to address the issue of network attackers creating a large number of transactions in a very short amount of time without completing the transaction process during cross chain asset exchange using hash time lock algorithms.This can cause a large number of transaction timeouts,resulting in a large amount of junk transaction information in the blockchain network and blocking the blockchain network.This method introduces a trading margin mechanism,which controls the length of time lock that can be set when creating cross chain transactions through user node reputation points.This algorithm can quickly release transactions with time lock timeouts,reducing the impact of node wrongdoing on the blockchain network.In addition,a trading margin mechanism has been established to further increase the cost of node wrongdoing and ensure the normal operation of cross chain transactions.
