摘要/Abstract

摘要： 针对联盟链在复杂应用场景下权限管理分散、业务扩展困难、读写集中和多合约间弱事务性的缺点，提出了一种面向复杂应用场景的联盟链多链协同方案。该方案利用区块链网关统一管理用户访问权限，避免了访问权限管理的分散；提出支持逻辑链动态伸缩的链间路由机制，简化逻辑链的管理，降低业务扩展难度；设计读写分离机制，提升逻辑链的读写性能；构造基于TCC的事务方案，满足多业务合约之间的事务性操作。实验和分析结果表明，该方案有效提高了交易吞吐量，且在业务动态扩展和多合约间事务性方面有较好的支持。

Abstract: To address the shortcomings of decentralized authority management, difficult business expansion, centralized reading and writing, and weak transactionality between multiple contracts in complex application scenarios, a consortium chain multi-chain collaboration scheme for complex application scenarios is proposed. This scheme uses a blockchain gateway to manage user access rights, provides an inter-chain routing mechanism for dynamic scaling of logical chains, implements a read-write separation mechanism to improve performance, and employs a TCC-based transaction scheme to support multicontract transactions. Experiments and analysis results show that the proposed scheme effectively improves transaction throughput, and has better support for business dynamic expansion and multi-contract transactionality.
