An Indexing Approach of Historical States on Hyperledger Fabric

Abstract— A blockchain is a shared database that saves an unalterable ledger of the transaction. A public blockchain is the simplest to define and everyone can join the most active applications. It can only operate a limited number of transactions and storage size. The processing time of the transaction on the block is also slow. A consortium blockchain supports many of the same advantages with private blockchain but operates under the leadership of a group instead of one organization. The transaction speed of a private blockchain is quicker than public blockchain. The trans action fee in private blockchain is not very costly. Hyperledger Fabric is private blockchain and permissioned network. Although Hyperledger Fabric is a modular architecture, great performance, and scalability, it cannot provide efficient indexing on file -system. In this paper, a new indexing approach is proposed to overcome the issue of indexing in the past states. A user - defined time for each transaction is added as an additional parameter to access into blockchain. This approach will provide the performance for Hyperledger Fabric.

Index Terms— blockchain, database, Hyperledger Fabric, file-system, user-defined time.
