Stand up a shared, tamper-proof viewership feed that broadcasters and advertisers both trust when setting ad rates. Each side independently checks the same verified numbers, removing the back-and-forth over whose data is correct before a rate is agreed.
Turn two conflicting audience datasets into one verified feed both sides negotiate against.
01.
Pull measurement onto one record. The Oracle Feeds module streams panel and return-path viewership data to the ledger, so broadcaster and advertiser read the same figures rather than separate vendor reports.
02.
Anchor each measurement snapshot. The Provenance Notary module seals every published viewership figure by digest and timestamp, making later quiet revisions detectable.
03.
Preserve the full series. Because each snapshot is immutable once anchored, neither side can retroactively reshape historical ratings to strengthen a negotiating position.
04.
Let each party check for itself. Advertiser and broadcaster both query the feed directly and confirm a figure against its anchored source without asking the other side to share a spreadsheet.
05.
Record every read and dispute. The Audit Logs module keeps a signed trail of which figures were used in which negotiation, giving both parties and any regulator a defensible record.
06.
Tie rates to verified data. An agreed ad rate references the exact anchored viewership snapshot it was priced on, so a later dispute is resolved against the numbers both sides signed.
Follow an audience measurement from ingestion through anchoring to its use as the shared basis for an ad-rate agreement.

Cerulea decomposes viewership sharing into modular contracts. Each layer ingests measurement, anchors the snapshot, exposes it for independent reads, and logs its use in a negotiation.
A shared viewership feed is a horizontal capability. Here is how different actors in the ad market put verified audience data to work.
Publish audience figures to a record advertisers already trust, shortening rate negotiations and defending premium pricing with data both sides can independently verify.
Key Asset Types
Price airtime against numbers confirmed at the source rather than a broadcaster's report, entering negotiations from the same verified feed as the seller.
Key Asset Types
Deliver panel and return-path data to a tamper-proof feed, turning their measurement into a citable, auditable input for every deal it informs.
Key Asset Types
Whether you are bridging a measurement firm's data platform or wiring a broadcaster's sales system into the feed, Cerulea routes both into one shared viewership record.
For panel and return-path measurement firms. Existing ratings exports are translated into signed on-chain viewership snapshots through the API gateway automatically.

Shared Ratings Record
Building a shared viewership feed with signed measurement intake, immutable snapshots, and negotiation-grade audit logs from scratch requires specialised engineers and long data-partner integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects audience-measurement integration benchmarks. Reconciling each provider's data formats, coding immutable snapshot logic, and building a trusted two-sided verification layer for an average market takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your feed and verification rules into pre-audited WebAssembly binaries and provisions the shared viewership ledger instantly.
