A Blockchain Solution to Improve the Traceability of the Agri-Food Supply Chain.

Since traditional agricultural traceability systems are largely centralized, traceability results are not always accurate, there is a risk of privacy data leakage. A trustworthy agricultural traceability system built on the Ethereum Blockchain was suggested to solve these issues. On the other hand, the use of Blockchain and IPFS (Interplanetary File System) dual storage architecture was created to lessen the blockchain’s storage demands for effective information queries and prevent data explosion. To stop the leakage of sensitive and other critical data, a method for data privacy protection is suggested based on cryptographic primitives. Using the Ethereum blockchain platform, a portion of the planned system was implemented, and a cost, performance, and security analysis were conducted in addition to a comparison with conventional agricultural traceability systems. The outcomes demonstrated that the proposed system could be effective and practical and satisfy future suitable application needs.
