MTdt:Enabling Meta-Transactions for Data Tracking of Industrial Workflow

Abstract

The decentralization and traceability of blockchain technology can realize the supervision of industrial Internet industry processes. As a jointly maintained distributed ledger, blockchain can provide an open, transparent and tamper proof information publicity platform. However, due to the huge amount of data and complex data interface of IOT equipment, blockchain cannot become a platform for direct access of IOT system. Nowadays, more and more decentralized applications are born. Building such services using emerging blockchain technology is a promising direction. We attempt to use the latest blockchain proxy strategy to solve data management problems in the system. We propose a blockchain sub-proxy model that traces workflows. Host data links to proxies, blockchain only store necessary information to ensure that subsequent transactions can be traced back to previous operations. Multiple tasks are represented by distributed agents to form a complete industry chain. In this model, industrial processes can be recorded asynchronously and on a large scale. Unlike centralized management processes, agents and blocks work together to ensure data storage efficiency and security.
