【Abstract】The seafood supply chain faces numerous challenges, including pricing volatility, limited traceability, fraud, overfishing, environmental concerns, inefficient logistics, and regulatory non-compliance, emphasizing the pressing need for innovative and sustainable interventions. This paper presents a novel framework, Sea-Trace-Pricing (STP), designed to address these challenges by improving traceability, enhancing security, and reducing price volatility. The proposed STP framework dynamically determines prices by incorporating real-time factors such as market demand, seasonal variations, product quality, a fixed base price, and other relevant variables, enabling adaptive price allocation based on current conditions. The proposed STP framework leverages Hyperledger Fabric blockchain to effectively implement and manage its core functionalities. The proposed STP framework automates transactions by utilizing chain code. It ensures that all stakeholders have access to accurate, real-time data while supporting transparent and fair pricing mechanisms. Additionally, the proposed STP framework employs the InterPlanetary File System (IPFS) for decentralized storage of associated records, enhancing security and safeguarding the seafood supply chain against fraud and unauthorized substitutions. We employed Hyperledger Caliper to evaluate the performance of the STP framework in terms of throughput and latency for both open and query functions. The results indicate that STP achieves an average throughput of 41.6 Transactions Per Second (TPS) for query functions and 38.87 TPS for open functions. In terms of latency, the proposed STP framework achieves an average latency of 2.745 seconds for queries and 5.175 seconds for open functions, demonstrating its capability to efficiently handle real-time data processing demands. We have conducted an energy consumption analysis of the proposed framework, focusing on the RAFT consensus mechanism used for network validation, the IPFS for file uploading and retrieval, and the communication network. Additionally, we have also analyzed measures to protect the proposed STP framework against various attacks, including DDoS attacks, Sybil attacks, and Man-in-the-Middle (MITM) attacks. Our observations reveal that the proposed STP framework outperforms existing solutions and holds significant potential to transform seafood distribution by ensuring traceability, improving market efficiency, and enhancing consumer confidence.
