Abstract
Counterfeit products cause financial losses for both the Manufacturer and the end-user, e.g., fake foods and medicines pose significant risks to the public’s health. Moreover, it is challenging to bring trust into the product’s supply chain, preventing counterfeit goods from being distributed throughout the network. However, fake product detection
methods are expensive and need to be more scalable, whereas a unified traceability system for the packaged product is not available. Therefore, this research proposes a product traceability system, named Trusted Traceability Service (TTS), using Blockchain and Self-Sovereign Identity (SSI). TTS can be incorporated across diverse industries because of its generic and manageable four-layer product packaging strategy. Blockchain-enabled SSI empowers the distributed nodes to verify them without a centralized client-server authorization architecture. Moreover, due to its distributed nature, the proposed TTS framework is scalable and robust with the combination of web3.0 distributed application development. The adoption of Fantom, a public blockchain infrastructure, allows the proposed system to handle thousands of successful transactions more cost-effectively than the Ethereum network. The deployment of the proposed framework in both public and private blockchain networks demonstrates its superiority in execution time and the number of successful transactions.
