Abstract:
The Internet of Things (IoT) and Blockchain distribution ledger technology as a concept is enchanting facilities and industrial developments with advanced implements in many applications. The IoT and Blockchain market is further expected to develop three times from current development by 2025. Though many IoT applications have major challenges in safest data transaction and scalability issues while increasing the number of IoT devices. Practical Byzantine Fault Tolerance (PBFT) is a widely used form of decentralized consent, however the network node's confidence in PBFT cannot be guaranteed, as well as the mechanism of reaching consensus will consume a large amount of network services. The article suggests the novel consensus process, which is referred to a Hybrid consensus blockchain algorithm and control authentication on Trust. The Internet of Things applications are integrated with a blockchainbased decentralized system that authenticates the IoT devices through distributed control authentication. This hybrid consensus blockchain method provides security for transactions and access to unauthorized devices is restricted. The PBFT algorithm using a decentralized network system using blockchain has no restriction of IoT devices. Even malicious users create the grouping into the network that has been controlled by the distributed control authentication method. Further then malicious users are rejected from the decentralized network. In this paper, we propose the Hybrid consensus blockchain and PBFT algorithm ensure the safest data transaction through blockchain technology and improves the performance of the decentralized network. Finally, we have presented a Hybrid Consensus algorithm to be utilized in the PBFT method which enables the safest data transaction.
