摘 要
Abstract—The blockchain technology, the core of FinTech, will
soon be adopted for more and more applications in the future.
However, the existing blockchain implementation supports very
limited query operations and the response time of the supported
operations grows with the number of blocks. To address these
issues, we propose HyperQL, which is an query layer on the
top of the blockchain in Hyperledger Fabric. The HyperQLenabled
Hyperledger Fabric uses the block listener to monitor
the response message of generated blocks in real-time. After
the handler filters useless data, HyperQL stores the data and
updates entries in PostgreSQL, a NewSQL database system. An
interface is provided for users to query the HyperQL-enabled Hyperledger
Fabric. The proposed HyperQL-enabled Hyperledger
Fabric supports full SQL operations with high performance and
reliability. The experiment results show the excellent performance
of important query operations and all advanced query types in
the HyperQL-enabled Hyperledger Fabric.
