An Indexing Approach of Historical States on Hyperledger Fabric

Abstract

A b lockchain 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 b lockchain. The transaction fee in private blockchain is not very costly. Hyperledger Fabric is private blockchain and permissioned network. A lthough 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 userdefined time for each transaction is added as an additional parameter to access into blockchain. This approach will provide the performance for Hyperledger Fabric.
