Deedline

Deedline is a cryptographic chain-of-title registry. Every deed carries its own hash-linked, proof-of-work-sealed blockchain, and each handover is signed by the recorded owner, held in escrow, then unlocked by a one-time claim code that only the intended grantee can redeem. Real ECDSA P-256 keys and encrypted vaults — all offline in your browser, fully verifiable.
