Identity protocols enable farmers market vouchers via decentralized identifiers (DIDs) and verifiable credentials (VCs). Low-income users receive government-issued VCs proving eligibility (e.g., income level, residency), stored in mobile wallets. Vendors use smart contracts to validate VCs instantly, deducting voucher balances securely. Zero-knowledge proofs ensure privacy by letting users prove eligibility without revealing sensitive data (e.g., exact income). Blockchain ledgers track voucher usage, preventing fraud and enabling audits.
