Verifiable Identity and Valuation Insight for Indian Fisheries Using Blockchain

Blockchain is an emerging technology with a core emphasis on decentralization. Along with this, blockchain is immutable and follows a consensus, thereby promoting data ownership and data provenance to its users. The concept of self-sovereign identity further promotes a decentralized and distributed network. The use cases of blockchain extend beyond the cryptocurrency world. Using decentralized identifiers, smart contracts, and zero-knowledge proofs, verifiable credential models can enhance multiple areas of society. This paper focuses on establishing a communication channel between fishermen and customers within India's fisheries sector, leveraging blockchain technology. The system is designed to be fully traceable and trackable, ensuring transparency. Fishermen retain ownership of their data, empowering them to receive fair prices, while consumers gain confidence in the authenticity of their purchases. To support trust, a data-driven layer analyzes state-wise valuation and pricing trends from 2020 to 2023. These insights help verified fishermen and buyers make informed decisions with greater transparency and regional context.
