Blockchain based Agri food Supply chain using AI Smart Contracts

Abstract

Blockchain technology offers a revolutionary way to improve the agricultural food supply chain's traceability, security, and transparency. As global food production and consumption continue to increase, systems that can efficiently track and verify food products from farm to table are becoming more and more important. Food safety and quality are a concern because current supply chain models frequently have problems with data integrity, fraud, and transparency. This paper proposes a comprehensive framework that incorporates a multi-layer architecture, including a data layer, blockchain layer, AI layer, traceability chain, and off-chain databases, to address these problems. The data layer collects and processes relevant data from all stakeholders in the agricultural supply chain to guarantee accurate and consistent data flow.Trade and delivery events are permanently and explicitly recorded by the blockchain layer, which uses smart contracts to automate transactions and enforce adherence to predefined standards.The suggested method improves data security and privacy by combining Artificial Intelligence (AI) with Multi-Party Computation (MPC) to give intelligent, privacy-preserving analytics.This link allows for collaborative verification and forecast findings without revealing personal participant information.Additionally, a Trusted Execution Environment (TEE) ensures tamper-proof operations by securely isolating critical calculations behind a hardware enclave. Participants may confirm that all data stored or off-chain is genuine and unaltered because of hash functions, which also offer data immutability and integrity. The proposed blockchain-based smart contract solution works effectively with transaction quantities between 25,000 and 28,500 Gwei across various Agri-Food Supply Chain operations. The average transaction time, which ranges from 0.001 to 0.0025 ms, demonstrates low latency and excellent responsiveness
