Research on Performance Scalability of State Grid chain-Data Side chain

Blockchain is a global research hotspot with the technical characteristics of building trust at low costs in open networks. However, the blockchain scalability problem has become the bottleneck of further application development, with the fast and widely spreading applications. This paper first analyzes the endogenous reasons that restrict the performance improvement of blockchain, and then summarizes the technology principles of three-layer blockchain scalability proposed by the current academia and enterprises, and makes a comparative analysis on the scalability effect, technical difficulty and practical application. Finally, we propose a distributed autonomous management solution for area partition and business channel, which guides an easy and executable scalability route for the State Grid chain-data side chain (SG-DSC).
