Abstract: This paper presents a blockchain-based prototype for enhancing traceability and data integrity in the tea supply chain through a Final Seal Verification mechanism. The system integrates Ethereum blockchain (via Ganache and Truffle), Node.js, Solidity smart contracts, and Laravel to ensure the authenticity of critical supply chain events. By hashing and sealing traceability data onto an immutable blockchain, the system can detect tampering attempts and provide customers with a reliable method of batch verification via QR codes.
