摘　　要：针对在交易双方使用哈希时间锁定(HTLC)进行跨链交换的过程中,某一节点或中间节点可能因故离线或恶意搁置交易,导致其他正常节点无法在时间锁解锁之前及时回滚交易并收回资产而造成的交易效率低下和资产安全问题,提出了一种由决策机制驱动的时增心跳哈希锁定跨链协议。该协议将传统的单一阶段时间锁改进为两个阶段,通过加入时增机制、心跳检测机制和决策机制提高在超时攻击情况下资产收回的效率,避免“重复支付”的问题。实验结果表明,该协议克服了传统HTLC算法在遭遇超时攻击时资产无法快速解锁的问题,提升了交易的稳定性,也确保了交易双方的资产安全。In the process of cross-chain exchange between two parties using the Hashed TimeLock Contract(HTLC),a node or intermediate node may be offline or maliciously shelve the transaction for some reason,which leads to other normal nodes not being able to roll back the transaction in time and retrieve the assets before the time-lock is unlocked,resulting in low transaction efficiency and asset security risks.This paper proposes a cross-chain protocol for time-increasing heartbeat hashed lock,which is driven by a decision mechanism.This protocol enhances the traditional single-stage time lock by incorporating a time increment mechanism,heartbeat detection mechanism,and decision-making mechanism to improve the efficiency of asset recovery in the event of a timeout attack and to prevent the"duplicate payment"problem.Experimental results indicate that the protocol overcomes the issue of assets being unable to be quickly unlocked when traditional HTLC algorithms encounter timeout attacks,while simultaneously enhancing transaction stability and ensuring the asset security of both trading parties.
