Research on Blockchain Data Availability and Storage Scalability

Blockchain adopts a chain data structure, and the characteristics of blocks that can only be added cannot deleted make total number accumulate over time, forcing resource-constrained nodes to become degraded in order alleviate increasingly severe storage pressure. Degraded store partial blocks, although improving scalability blockchain reducing redundancy will lead decrease availability. To address problem scalability, quantitative research is needed on Based summary existing definitions availability, we propose definition availability for blockchain. By analyzing synchronization process transaction lifecycle, key factors affecting were extracted, measurement model was constructed based node types. On this basis, relationship linking find range meets target The experimental results indicate measure levels different scalable schemes. between guide setting
