IEEE Project Abstract

Blockchain is experiencing rapid development and has the full potential of revolutionizing the IoT platform in industrial field. In this paper, a light-weighted Blockchain-based Platform for IIoT is presented to address security, trust, and island connection problem in the process of IIoT ecosystem construction. BPIIoT is comprised of the on-chain network and the off-chain network. All transactions are processed in the on-chain network, such as including digital signature based on access control, and programmable permission. The off-chain network deals with storage, complex data processing and other problems that blockchain cannot solved. Smart contract is utilized as the service contract of consumers and manufacture resources, providing on-demand manufacturing service. Two smart application cases,manufacturing equipment data sharing and maintenance service sharing from smart manufacturing, are implemented to explain the smart contract for equipment maintenance service and status data sharing service throughout Maintenance, Repair and Operation service network by BPIIoT.
