DIGITAL ASSET MANAGEMENT

Absstract of: US2025233747A1

A system and method are provided for issuing vehicle titles in a manner that guards against title washing using a permissioned blockchain network. Upon receiving a title issuance request, a global asset registry ledger is queried to retrieve historical vehicle data, including prior branding, liens, and registration events. A predictive validation index (PVI) is computed to assess the risk of title fraud. Based on the PVI, a proof of attestation policy is dynamically enforced via a smart contract that requires cryptographic endorsements from certified peer nodes. When sufficient attestations are received, the smart contract commits a new title issuance transaction to the blockchain and generates a digital title token linked to the vehicle identification number. The system maintains immutable audit records and supports real-time notifications, jurisdiction-specific policies, and secure integration with external systems such as dealerships and title authorities.
