The food supply chain is the most complex and fragmented of all supply chains. The production is found all over the world both on land and in water. A lot of the producers and intermediaries are difficult to identify and track. For all the participants in the production chain this creates uncertainty and risk. Mitigating this uncertainty comes at a cost, and the outcome may still be insufficient. Examples of problems that have been difficult or impossible to solve with current technologies include establishing reliable provenance and preventing fraud and counterfeiting. These issues can have knock-on effects on public health and the environment, and reduce financial costs of unnecessary recalls of food products. The project “supply chain traceability solution: enhancing accountability using solidity for blockchain” is a comprehensive initiative geared towards elevating preserved food safety standards through the implementation of an advanced traceability system. Recognizing the critical importance of accountability in the context of food supply chains, the project leverages the solidity programming language to establish a secure and transparent blockchain-based solution. To overcome the above challenges, a blockchain based food traceability system (BIFTS) is proposed in this study, to achieve the integration of blockchain technology for effective and efficient traceability and support shelf life adjustment and quality decay evaluation for improving quality assurance. For the sake of better computational load, the blockchain is modified as a lightweight blockchain to be associated with cloud computing to support monitoring, and can be vaporized after the entire life cycle of traceability to release computational resources of the system. By using such a reliable data source, the decision support in food quality can be made by using fuzzy logic to determine adjustment of shelf life, rate, and order of quality decay, according to different situations for each batch of perishable foodstuffs at food processing sites. Therefore, the proposed traceability model is extended to the modern food supply chain environment, resulting in reliable and intelligent monitoring, food tracking, and quality assurance. Preserved foods, susceptible to contamination and spoilage risks, demand a unique approach to traceability. the proposed system meticulously records and timestamps key information at each stage of the supply chain. solidity, a programming language specifically designed for smart

contracts on the Ethereum blockchain, plays a pivotal role in ensuring the integrity and immutability of the recorded data. By utilizing blockchain technology, the project addresses the inherent challenges of trust and transparency within the supply chain. stakeholders can access a decentralized ledger that offers a tamper resistant record of the entire journey of preserved food products. This not only facilitates real time monitoring but also expedites the identification and resolution of issues, thereby enhancing overall food safety. The traceability solution's emphasis on accountability serves as a proactive measure to mitigate risks associated with preserved food products. The decentralized nature of the blockchain, coupled with the programming robustness of solidity, provides a resilient framework for safeguarding the integrity of the traceability data. In conclusion, this project not only addresses the specific challenges of preserving food safety but also contributes to advancing the broader field of supply chain traceability through innovative blockchain technology.
