A decentralized receipt verification protocol preventing fraud and ensuring permanent, verifiable proof of purchase using DCAI L3 scaling technology
ResitDaun addresses the $50B+ global retail fraud problem by moving the "Source of Truth" from private merchant databases to a public, immutable ledger.
Key Technical Features:
Immutable Audit Trail: Once a receipt is issued on the L3, it cannot be edited or deleted by staff, eliminating internal refund fraud.
Interoperability: Receipts are stored as on-chain data, making them instantly compatible with DeFi accounting tools and digital warranty ecosystems.
Privacy-Preserving Verification: Uses hashing to ensure transaction details are verifiable without exposing sensitive consumer PII (Personally Identifiable Information) on-chain.
DCAI L3 Synergy: We leverage DCAI's L3 for high-speed data access and transaction execution, ensuring the "checkout" experience remains seamless for the end-user.
