Blockchain Backed Survey Authenticity Verification

via “blockchain-backed survey authenticity verification”

via “blockchain-verified mapping data integrity”

via “decentralized identity verification for blockchain transactions”

Unique: Multi-standard signature verification (EIP-191, EIP-712, SIWE) with optional revocation list checking and on-chain identity registry integration, rather than single-standard verification or offline-only signature validation

vs others: Provides stronger authenticity guarantees than signature verification alone by checking against revocation lists and identity registries, and supports multiple signature standards for flexibility

via “decentralized ownership verification”
