The Industrial Internet of Things(IIoT) plays a vital role as a fundamental technology supporting intelligent manufacturing. Existing IIoT platform adopts cloud-edge design, the centralized cloud stores a large amount of sensitive data, which is vulnerable to attack and faces the risk of single point of failure. As a distributed system, blockchain enables secure and robust IIoT systems. Therefore, this paper builds a blockchain-based IIoT platform to store the data in IIoT into the blockchain and ensure security through a decentralized and distributed consensus mechanism. However, the existing blockchain platforms have low throughput and cannot meet the demand of high concurrent data processing. To solve this problem, this paper designs a dual data compression optimization scheme, which can effectively reduce the size of the transaction and improve the transaction processing speed. This scheme provides an effective solution for promoting the deep application of blockchain and IIoT.
