Parts Provenance Engine

Kill the counterfeit.
Prove every part.

Trace each component from Tier-2 to the finished vehicle on one shared consortium network. The Traceability Ledger and Device Attestation confirm authenticity at every tier, while the Quality and Recall Ledger isolates any defect down to the exact part lot.

The Foundation

The Execution Mechanics

Turn an opaque multi-tier supply chain into a single, tamper-evident record of authenticity.

01.

Multi-Tier Traceability

Replace blind faith in suppliers. The Traceability Ledger records every custody transfer from Tier-2 casting to Tier-1 assembly to OEM line, so no substitution slips in unseen between tiers.

02.

Device Attestation

Bind identity to hardware. Device Attestation anchors a cryptographic signature from the factory press or laser marker to each part serial, making a cloned or grey-market unit fail verification instantly.

03.

Service-Point Verification

Reject fakes at the bay. A technician scans a part before fitting it, and a component with no valid on-chain record returns a hard failure instead of a warranty landmine.

04.

Lot-Level Recall

Contain defects precisely. The Quality and Recall Ledger maps each serial back to its production lot, so a recall targets the exact affected batch rather than an entire part number.

05.

Approved-Supplier Registry

Enforce sourcing rules on-chain. When a counterfeit surfaces, its origin resolves to a specific vendor, who is flagged and removed from the approved list across every plant at once.

06.

Warranty Evidence

Settle claims from proof. Each fitted part carries a verifiable authenticity record, so warranty disputes rest on cryptographic evidence rather than a contested paper invoice.

The Provenance Lifecycle

Follow a single brake component from its Tier-2 origin to the moment a technician verifies it at the service bay.

Smart Contract Anatomy

Cerulea decomposes parts provenance into modular contracts. Each layer mints, attests, transfers, and verifies a component without any single tier controlling the authenticity record.

Applicability Across the Spectrum

Parts provenance is a horizontal capability. Here is how different actors across the automotive supply chain put the shared authenticity record to work.

OEMs & Assemblers

Bind every verified component to a VIN on the line and remove counterfeit suppliers from the approved list the moment a fake is traced, cutting warranty exposure and field failures.

Key Asset Types

  1. 1Bound Components
  2. 2Approved Suppliers
  3. 3Recall Lots

Tier-1 & Tier-2 Suppliers

Attest each part at the press and co-sign custody upward, turning provable authenticity into a competitive advantage and a shield against substitution claims.

  1. 1Attested Parts
  2. 2Custody Records
  3. 3Lot Certificates

Dealers & Service Centres

Scan replacement parts before fitting and reject any unit with no valid record, protecting technicians, drivers, and the dealer's warranty standing.

  3. 3Authenticity Checks

Network & Execution Architecture

Whether you are bridging legacy MES and PLM systems from Tier-1 plants or capturing press signatures from Tier-2 devices, Cerulea routes both into one shared authenticity record.

Track A: Enterprise MES Bridging

For OEMs and Tier-1 suppliers on legacy MES and PLM. Existing production events are translated into signed on-chain part transitions through the API gateway automatically.

Track B: Factory Device Capture

For Tier-2 presses and laser markers on the shop floor. Each device signs a part attestation at production and routes it directly to the ledger through its wallet.

Technical Methodology

The legacy timeline reflects automotive supply-chain integration benchmarks. Wiring together each tier's MES, building custom attestation and custody logic, and shipping a lot-level recall index for an average network takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your attestation and custody rules into pre-audited WebAssembly binaries and provisions the shared consortium ledger instantly.
