A secure and trusted consensus protocol for blockchain-enabled supply chain management system

It is encouraging to see blockchain technology take off as a practical means of improving supply chain management. Blockchain can help to lower fraud, boost efficiency, and improve the trust of those involved in the supply chain by offering a secure, decentralized, and transparent platform for tracking and verifying transactions. Additionally, blockchain can help with the creation of smart contracts, which can automate the completion of some transactions and improve the supply chain's overall efficiency. Despite ongoing challenges like scalability and interoperability, blockchain technology has the potential to transform supply chain management and build a more robust, sustainable, and reliable global economy. To increase transparency, accountability, and trust in the supply chain, this article suggests using a Proof of Reputation (PoR) consensus protocol in a blockchain-based supply chain management system. The protocol gives each participant a reputation score based on their previous actions and behavior, and uses this score to securely and decentralized validate transactions and add new blocks to the blockchain. The article offers a collection of Fair-Exchange Assessment Metrics for assessing node reputation as well as an assessment model for choosing the best consensus protocol based on particular needs and objectives. The proposed model, BCSC, outperforms the current model, BRBC, in terms of interference ratio, fair data exchange ratio, and process overhead, according to experimental results. The suggested method has the potential to boost the security, scalability, and effectiveness of supply chain blockchain systems.
