A Blockchain-Integrated IoT System Leveraging Hyperledger Fabric

Blockchain technology has been increasingly applied across various fields due to its advantages in distribution and security. Its integration with IoT devices is particularly promising, given their distributed deployment and limited computational capabilities. This paper presents a solution based on the Hyperledger Fabric framework, leveraging the strengths of blockchain while addressing the limitations of traditional blockchain systems, such as the inability to support deletion and modification operations. The proposed approach integrates IoT devices and evaluates the performance of two consensus algorithms, PBFT and RAFT, to highlight their respective efficiencies.
