Vehicle Identity Ledger

Anchor the VIN.
Expose the history.

Hold a complete, tamper-evident vehicle history on a shared network. The Traceability Ledger, Device Attestation, and DID and VC Ledger bind every event to the VIN, while the Provenance Notary anchors the record so cloning and hidden accident history become detectable.

The Foundation

The Execution Mechanics

Turn a manipulable central database into a single, cryptographically bound life record for every vehicle.

01.

VIN-Bound Events

Anchor every event to identity. The Traceability Ledger ties each service, accident, and ownership change to the VIN, so a vehicle's history is one continuous chain rather than scattered records.

02.

Attested Odometer

End mileage fraud. Device Attestation captures signed odometer readings straight from the cluster, making a 40,000 km rollback mathematically detectable against the prior anchored value.

03.

Verifiable Credentials

Bind claims to issuers. The DID and VC Ledger lets insurers, inspectors, and dealers issue signed credentials for a VIN, so a claim of clean title carries a verifiable issuer signature.

04.

Clone Detection

Break the duplicate. The Provenance Notary anchors a single canonical VIN record, so a cloned plate on a second vehicle collides with the genuine chain and is flagged.

05.

Instant Buyer Access

Give buyers a trusted window. A buyer scans a VIN and reads the full accident, odometer, and title history in seconds, with no account and no reliance on a single database operator.

06.

Cross-Border Portability

Carry history across markets. Because the record lives on a shared network, an imported vehicle brings its verified history with it instead of resetting at the border.

The Vehicle Lifecycle

Follow a single vehicle from factory registration through service and accident events to the moment a used buyer verifies its history.

Smart Contract Anatomy

Cerulea decomposes vehicle identity into modular contracts. Each layer anchors, attests, credentials, and exposes a VIN history without any single registry operator able to rewrite the record.

Applicability Across the Spectrum

A VIN-bound history is a horizontal capability. Here is how different actors in the vehicle lifecycle put the shared record to work.

Used-Car Marketplaces

Attach a verifiable history to every listing so buyers see accidents, mileage, and title status up front, cutting fraud disputes and lifting trust in the platform.

Registries & Regulators

Anchor titles and inspections to the canonical VIN and query the ledger directly, replacing a manipulable central database with a tamper-evident shared record.

Network & Execution Architecture

Whether you are bridging legacy DMV and dealer systems or capturing signed readings from vehicle clusters, Cerulea routes both into one shared VIN history.

Track A: Registry & Dealer Bridging

For DMVs, insurers, and dealer groups on legacy systems. Existing title and service events are translated into VIN-bound on-chain records through the API gateway automatically.

Track B: In-Vehicle Telemetry Capture

For instrument clusters and connected vehicles. Each cluster signs an odometer and event reading and routes it directly to the VIN record through its device wallet.

Technical Methodology

The legacy timeline reflects registry integration benchmarks. Binding each DMV, insurer, and dealer system, building custom odometer attestation and credential logic, and shipping a public VIN resolver for an average network takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your identity and credential rules into pre-audited WebAssembly binaries and provisions the shared VIN ledger instantly.
