Track each reference sample as it moves between labs in a proficiency testing round and anchor every submitted result for accreditation review. The administrative burden of coordinating distribution and comparison collapses into one verifiable record.
Replace scattered spreadsheets and email with one shared, tamper-evident record of samples and results.
01.
The Traceability Ledger records each reference sample sent to each participating lab, so the coordinating body always knows exactly where every aliquot went.
02.
The Provenance Notary seals each lab's submitted result to the sample and the round, preventing any later adjustment once the value is committed.
03.
The Compliance Attestations module binds each result to the lab's accreditation status, giving the assessor a verifiable link between capability and performance.
04.
Results are committed before the reference value is revealed, so no lab can align its answer to the consensus after the fact.
05.
When the round closes, every submission is compared against the assigned value in one pass, producing an auditable performance record per lab.
06.
The accreditation body queries the ledger directly for any round, replacing chased paperwork with a live, verifiable view of participation and results.
Follow one reference sample from dispatch through blind result submission to accreditation reconciliation.

Cerulea decomposes proficiency testing into modular contracts. Each layer distributes, commits, reveals, and reconciles a round without the scheme provider hand-collating spreadsheets.
Verifiable proficiency testing is a horizontal capability. Here is how different actors in the accreditation chain put it to work.
Prove blind participation and performance in every round without maintaining private evidence, and demonstrate accreditation readiness from a shared record rather than a self-assembled folder.
Key Asset Types
Coordinate sample distribution and result collection for many labs in one ledger, eliminating the spreadsheet reconciliation that makes large rounds administratively heavy.
Key Asset Types
Query participation and performance directly for any round, replacing chased documentation with a live, verifiable view of each lab's proficiency evidence.
Key Asset Types
Whether you are bridging a scheme provider's coordination platform or capturing result submissions from lab systems, Cerulea routes both into one round record.
For proficiency scheme operators on legacy coordination tools. Distribution and reveal events are translated into signed on-chain round transitions through the API gateway.

Building a proficiency testing ledger with blind commitment, controlled reveal, and automated reconciliation from scratch requires specialised engineers and long scheme integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects accreditation scheme integration benchmarks. Building sample distribution tracking, a blind commit-reveal flow, and automated reconciliation for an average scheme takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your distribution and scoring rules into pre-audited WebAssembly binaries and provisions the shared round ledger instantly.
