Shared Audit Settlement Layer

Audit once.
Trusted by many.

Publish a supplier's verified audit results to participating OEMs on a shared network so one recent audit replaces many duplicate ones. Compliance Attestations record each result, and the DID and VC Ledger with Role-Based Access Control governs exactly who reads it.

The Foundation

The Execution Mechanics

Turn repeated, siloed supplier audits into one shared, permissioned, always-current record.

01.

Single Audit Publication

Record a result once. An accredited auditor writes a supplier's verified outcome to the shared network, and participating OEMs read that same result instead of scheduling their own.

02.

Attested Findings

Bind evidence to the verdict. Compliance Attestations capture each finding, corrective action, and closure under the auditor's signature, so a shared result carries provable substance.

03.

Role-Based Access

Show the right OEM the right slice. Role-Based Access Control governs read scope, so a supplier exposes an audit to approved customers without publishing it to the whole network.

04.

Credentialed Auditors

Trust the source. The DID and VC Ledger verifies the auditor's accreditation before a result is accepted, so a shared record only ever originates from a qualified assessor.

05.

Currency Enforcement

Keep evidence fresh. Each audit carries a validity window, and the network flags a result approaching expiry so OEMs never rely on quality evidence that has gone stale.

06.

Duplicate Elimination

Cut the redundant burden. Because multiple OEMs consume one recent shared audit, the repeated on-site assessments that exhaust suppliers and OEM quality teams fall away.

The Shared Audit Lifecycle

Follow a single supplier audit from an accredited assessment through permissioned sharing to reuse by several OEMs.

Smart Contract Anatomy

Cerulea decomposes shared supplier audits into modular contracts. Each layer accredits the assessor, attests the result, scopes access, and serves current evidence without any OEM owning the record.

Applicability Across the Spectrum

Shared supplier audits are a horizontal capability. Here is how different actors put the permissioned quality record to work.

Aerospace OEMs

Qualify a supplier from one recent shared audit instead of dispatching a team for a redundant on-site assessment, freeing quality engineers while relying on evidence that stays current.

Component Suppliers

Publish a single verified audit and expose it selectively to approved customers, ending the cycle of repeated visits from every OEM against largely the same standards.

Key Asset Types

  1. 1Published Audits
  2. 2Access Grants
  3. 3Evidence Bundles

Accreditation Bodies

Anchor auditor accreditations and standard references so every shared result on the network is traceable to a qualified assessor working against a recognised specification.

Network & Execution Architecture

Whether you are bridging OEM quality systems or capturing audit results from an assessor's field tablet, Cerulea routes both into one shared, permissioned record.

Track A: OEM Quality System Bridging

For OEMs on legacy supplier-quality management systems. Existing qualification records are translated into scoped on-chain reads through the API gateway automatically.

Track B: Assessor Field Capture

For accredited auditors on a field tablet. A signing app publishes each verified result from an auditor wallet and routes it directly to the shared ledger.

Technical Methodology

The legacy timeline reflects multi-party quality-system integration benchmarks. Aligning several OEMs on a shared schema, building role-based access, and shipping currency enforcement takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your audit and access rules into pre-audited WebAssembly binaries and provisions the shared audit ledger instantly.
