Blockchain-Based Supply Chain Framework in IoT with Trust-Driven Hybrid Consensus Mechanism
摘要
The security and privacy issues have grown more pressing since multi-agent systems have developed so quickly. Since its introduction, blockchain technology has attracted a lot of attention because of its benefits including decentralization, accessibility, traceability, and the capacity to function without external trust. The complexity of today’s supply chains is increasing, and data integrity and traceability are major issues. In order to properly solve these issues, blockchain technology presents a viable way to rethink supply chain traceability. To ensure network consistency even when there are unconfirmed traders present, a trust-enabled hybrid consensus mechanism is suggested in this study. In order to control blockchain network access according to predetermined accessibility guidelines, the suggested approach includes an authorization system. The model assesses the legitimacy of the data by combining several data sources, allowing agents and resources to communicate with ease. The minimal transaction time of 0.856 ms, memory use of 87.684 KB, and responsiveness of 3.599 ms are the three primary performance criteria for secure data transfer that are used to evaluate the model’s effectiveness.
