基于星火区块链的跨链机制

针对当前区块链技术飞速发展的过程中,不同区块链之间相对孤立,数据不能交互共享的问题,提出一种基于星火区块链的跨链机制.首先,对常见跨链技术和当前主流跨链项目作了分析,研究了不同技术和项目的实现原理,并总结了它们的区别和优缺点;然后,利用主子链模式的区块链架构,设计了智能合约组件、交易校验组件、交易超时组件等关键核心组件...

Cross-chain mechanism based on Spark blockchain

Considering different blockchains being isolated and the data interaction and sharing difficulties in the current rapid development process of blockchain technology， a cross-chain mechanism based on Spark blockchain was proposed. Firstly， common cross-chain technologies and current mainstream cross-chain projects were analyzed， the implementation principles of different technologies and projects were studied， and their differences， advantages and disadvantages were summarized. Then， using the blockchain architecture maned main-sub blockchain mode， the key core components such as smart contract component， transaction verification component， transaction timeout component were designed， and the four stages of cross-chain process were elaborated in detail， including transaction initiation， transaction routing， transaction verification and transaction confirmation. Finally， the feasible experiments were designed for performance test and security test， and the security was analyzed. Experimental results show that Spark blockchain has significant advantages compared to other blockchains in terms of transaction delay， throughput and spike testing. Besides， when the proportion of malicious nodes is low， the success rate of cross-chain transactions is 100%， and different sub chains can conduct cross-chain transactions safely and stably. This mechanism solves the problem of data interaction and sharing between blockchains， and provides technical reference for the design of Spark blockchain application scenarios in the next step.
