Blockchain-based label coverage storage query scheme

Abstract

Blockchain technology realizes information traceability by constructing chain network structure; Through distributed storage and consensus mechanism, each transaction can be verified and shared. Hyperledger Fabric has the characteristics of deep encryption, convenient expansion, flexible deployment and pluggability, and provides a modular distributed ledger platform for the needs of different applications. Combining the blockchain technology with the storage and sharing requirements of railway engineering data and drawing information, this paper first introduces the related concepts of blockchain technology, Hyperledger Fabric and critical algorithms and puts forward a Coverage Tag Validation (CTV) for the storage of railway engineering data and drawing information, which can improve the query efficiency and optimize the results, and provide some reference for future research.
