Abstract
The prepared vegetable traceability system will be based on blockchain technology in order to guarantee the quality and safety of pre-made food, improve the traceability effect, and build a good trust bridge. Data is partitioned. and dynamic traceability is used to give the system the ability to adapt to various application scenarios. The super ledger blockchain implementation method, smart contracts for actual transaction accomplishment, and the HyperLedger Fabric framework are all used to create the pre-made food product traceability system. The method ensures the security and authenticity of the information on the quality of pre-made food products and alleviates the tough problems with the trade circulation of these items.
