Before revision:  While blockchain technology is leveraged to ensure data integrity in a distributed manner, Hyperledger Fabric (HLF) attracts attention with its distinctive strong point without requiring the power-consuming consensus protocol, that is , proof-of-work (PoW) . However, even though such security concerns can be mitigated using HLF , the additional processing time spent in HLF may emerge as another issue because most IoT devices handle real-time and latency critical jobs.
After revision:  While blockchain technology is leveraged to ensure data integrity in a distributed manner, Hyperledger Fabric (HLF) attracts attention with its distinctive strong point without requiring the power-consuming consensus protocol, that is , which is a private blockchain platform, has been leveraged for blockchain-enabled IoT (BC-IoT) networks. From the perspective of an IoT application, however , the additional processing time spent in HLF may emerge as another issue because most IoT devices handle real-time and latency critical jobs.
