SIBRAAR – BRAZILIAN AGRO-TRACEABILITY SYSTEM

The aim of this study is to implement a blockchain-based traceability system for monitoring sugarcane products produced by Granelli Mills. This system is designed to ensure data integrity and provide a reliable audit trail by leveraging the inherent immutability of blockchain technology. In cases where data tampering is suspected in the database, the blockchain can be accessed and compared to the database to identify any discrepancies. The system integrates traditional databases with blockchain technology, which serves as an effective method for storing the hash codes of blocks that contain brown sugar production data. These hash codes act as keys to access the corresponding production data stored on the blockchain. Each production batch is uniquely identified by a hash code that is generated and recorded on the blockchain. This hash code also forms part of a unique URL that allows consumers to access detailed product and production information for that specific batch. Granelli Mills uses this hash code to generate a QR code, which is printed on labels attached to packages of brown sugar and demerara sugar. The QR code simplifies access for consumers: by scanning it with a smartphone, they are directed to a web page displaying the relevant batch information. The Sibraar system serves as an effective example of how blockchain can be used to enhance traceability and transparency in supply chains.
