Verification of data integrity is required for external organization to fully trust the IIoT(Industrial Internet of Things) data that is produced internally. Adapting TTP(Trusted Third Party) for data integrity also brings up another trust issues, specially when that TTP is centralized. Blockchain technology uses consensus algorithm to synchronize every node’s data. In its process data is constantly verified and it provides immutability. With the use of immutability Blockchain can also be used to design data integrity verification system. However, with consensus algorithm being a burden to the network, it requires additional matter to increase the throughput for real-time IIoT data process. To mitigate these issues we have designed the data integrity verification system using Off-Chain concept witch combines centralized and decentralized mechanism. And after its implementation, we have conducted a comprehensive analysis of the system to show the feasibility of the designed system and measure the trade-off between data integrity and network resources.
