区块链跨链技术分析

Analysis of cross-chain technology of blockchain

随着区块链技术的发展,区块链项目也越来越多。由于区块链的封闭性,导致不同区块链形成一个个价值"孤岛",不同区块链之间的信息交互与价值转移问题亟待解决。跨链技术解决了不同链间资产与数据等跨链操作问题,在过去几年里已经有许多尝试和发展,跨链的主要模式包括哈希锁定、公证人机制、侧链与中继技术等。介绍了目前主要跨链技术的基本原理,总结分析了各个跨链技术的优势与劣势。

With the development of blockchain technology,more and more blockchain projects have appeared.Due to the closure property of the blockchain,different blockchains have become islands of value.The information interaction and value transfer problems between different blockchains need to be solved urgently.The cross-chain technology is to solve the cross-chain operation problems of assets and data between different chains.There are many attempts and developments on cross-chain technology in the past few years,and the major models of cross-chain include Hash lock,notary mechanism,side chain and relay technology,etc.The concept of each cross-chain technology was introduced,and the advantages and disadvantages of each cross-chain technology were summarized and analyzed.
