Blockchain Based Transaction Management System for IC Industry

With the development of Internet technology, all walks of life are undergoing industrial revolution and upgrading. Nowadays, many transactions in the integrated circuit (IC) industry chain have moved from offline to online, most of which are completed through trusted third-party platforms as the transaction medium. This transaction model, which relies on centralized institutions, is vulnerable to malicious cyberattacks, poses a risk of core technology theft for technology-intensive industries, and lacks the ability to trace the trajectory of transactions. To solve the above problems, this paper proposes a consortium chain-based transaction management system for the IC industry chain based on the transaction characteristics of commodities in the IC industry chain, designs an improved Raft consensus mechanism based on stability, credibility and contribution factors, a Prometheus-based data monitoring mechanism, and a set of smart contracts for on-chain transactions, implements a prototype system and tests its performance. The results show that the system can solve the above problems well and has high credibility and stability.
