Research On Optimization Model of High Availability and Flexibility of Blockchain System Based on Microservice Architecture

With the rapid development of blockchain technology and its wide application, the traditional monomer architecture has gradually exposed problems such as poor scalability, insufficient flexibility and difficult maintenance when dealing with complex business needs and large-scale user access. Therefore, this paper proposes an optimization model of blockchain system based on microservice architecture, which aims to solve the bottleneck of traditional blockchain system in availability, flexibility and performance through microservice architecture. By disassembling the blockchain nodes into multiple independent microservice modules, combined with reasonable interface and communication design, this paper realizes efficient collaboration and modular management of the system. At the same time, the introduction of multiple sub-chain architecture, so that each node can deploy multiple microservices according to business requirements, to meet the flexible requirements of different scenarios. In order to improve the system performance, this paper also designs a smart contract grouping and parallel processing mechanism to break through the performance bottleneck of blockchain in highly concurrent transactions and complex contract execution. The experimental results show that the blockchain system based on microservice architecture shows significant advantages in terms of availability, flexibility and performance, and provides new ideas and practical basis for the development and application of blockchain technology.
