Zero-Knowledge Proofs for Privacy-Preserving Agricultural Yield Verification: A Blockchain-Based Incentive System for Sustainable Farming Methods

Abstract

This paper presents a novel blockchain-based incentive system that protects farmers' privacy while promoting sustainable farming methods by using zero-knowledge proofs, or ZKPs. With this method, farmers can show that they've met their yield goals without giving away private production information. We implement the system as an Ethereum smart contract that uses cryptographic assurances to ensure correct reporting and distributes incentives based on verified crop yields. Our method addresses important problems in agricultural sustainability projects, like protecting privacy, the cost of verification, and making sure that rewards are shared fairly. The suggested answer affects sustainable agriculture policy, privacy-focused data exchange in supply lines, and the use of cryptographic methods in environmental governance.
