The cycle starts with suppliers obtain- ing certified organic materials, which are then processed by man ufacturers, distributed to retailers, andfinally purchased by consumers. Blockchain ensures that every transaction and logistics step is securely recorded,providingtransparencyandaccountability

Growers represent the farmers or producers who cultivate the raw materials used in food production. Their contribution marks the first step in the supply chain, and their activities are recorded on the blockchain for traceability.

After harvesting, raw materials are processed into usable forms by entities such as food processing plants. Blockchain technology tracks this transition, ensuring no tamperingorloss ofinformationabout the product’sorigin andquality.

Suppliers are responsible for the transportation and distribution of processed goods. Blockchain ensures transparency in logistics, recording critical data such as shipment routes, times, and conditions, reducing fraud or de-lays.

Manufacturers convert processed materials into finished products. Blockchain technology helps track compliance with safety and quality standards, ensuring that the goods meetregu-latoryandconsumerexpectations.

Retailers represent the final commercial step where finished goods are sold to consumers. Blockchain helps retailers provide verified information about the product’s originandjour-ney,fosteringtrustamongbuyers.
