Endorsement Policy for Industrial Internet of Thing with Private Blockchain

In the industrial Internet of Things (IIoT) environment, managing a significant amount of real-time sensing data generated by IIoT devices is a primary concern. Edge computing technology can effectively resolve this problem for low latency data exchange. However, it faces security challenges and management overhead of large volume of real-time IIoT traffic. In this paper, we propose to integrate a private blockchain into edge computing server systems to tack the challenges. The proposed system overcomes security challenges by allowing IIoT edge devices to execute smart contracts and verify transactions in private blockchain. In order to alleviate management overhead, we simplify the existing transaction process by introducing a novel endorsement policy. Performance evaluation shows that the proposed system can satisfy the low latency requirement and reduce energy consumption of the IIoT devices.
