摘要
伴随着区块链技术的飞速发展,各类区块链项目呈井喷式增长。在区块链项目数量呈现加速上升态势的同时,后续没有相应的配套措施,导致目前大部分的区块链项目无法互联互通。为了解决每个链都是独立的、垂直的封闭体系,让链与链之间的互操作性成为可能,文章基于哈希锁定技术,设计了一种改进的跨链技术,通过将主链资产双向锚定到侧链,利用哈希时间契约锁协议HTDLC,哈希锁防止信息篡改,时间锁限制交易时间,违约锁放置违约强制保障协议,实现资产跨链交易。
With the rapid development of blockchain technology,blowout growth of all kinds of blockchain projects.At the same time,the number of blockchain projects is increasing rapidly,and there are no corresponding supporting measures in the follow-up,which makes most of the current blockchain projects unable to interconnect.In order to solve the problem that each chain is an independent and vertical closed system,it is possible to make interoperability between chains.This paper designs a new cross-chain technology based on atomic swap.By anchoring the main chain assets to the sidechain in two directions,using the HTDLC,hashlock prevents information tampering,timelock restricts transaction time,and delylock places compulsory guarantee protocol to realize cross-chain transaction of assets.
