Broadcast Proof Verification Layer

Prove every airing.
Pay only on broadcast.

Anchor a timestamped proof for every booked advertisement, confirming it aired in its scheduled slot before any money moves. Payment sits in escrow and releases automatically the moment broadcast is confirmed, so advertisers stop paying for airings they cannot verify.

The Foundation

The Execution Mechanics

Turn an unverifiable broadcaster invoice into a cryptographic proof that gates the advertiser's payment.

01.

Slot Booking Escrow

Lock funds at booking, not before airing. The Escrow and Conditional Settlement module holds the advertiser's payment against a specific slot, so the broadcaster is guaranteed funds only once the ad actually runs.

02.

Proof-of-Broadcast Notary

Stamp every airing to the ledger. The Provenance Notary module anchors a timestamped, tamper-evident proof of each broadcast, binding the aired spot to its booked slot and creative.

03.

Airtime Oracle Feed

Pull confirmation from monitoring. A broadcast-monitoring oracle streams as-run logs and watermark detections to the contract, converting a claim of airing into verified data.

04.

Payment on Proof

Release funds automatically. Once the anchored proof matches the booked slot, escrow settles to the broadcaster with no manual sign-off and no dispute window.

05.

Compliance Attestations

Prove the ad met its terms. The Compliance Attestations module records that the spot ran at the agreed length, daypart, and channel, giving regulators and clients a verifiable trail.

06.

Discrepancy Evidence

Resolve missed airings from data. If a booked spot never anchors a proof, escrow returns to the advertiser and the gap is recorded as signed evidence rather than a phone-call dispute.

The Broadcast Proof Lifecycle

Follow a single advertising slot from booking through its confirmed airing to automatic, proof-gated payment.

Smart Contract Anatomy

Cerulea decomposes broadcast verification into modular contracts. Each layer books the slot, captures the airing, anchors the proof, and settles the escrow without the broadcaster grading its own homework.

Applicability Across the Spectrum

Proof-gated advertising is a horizontal capability. Here is how different actors in the airtime market put verified broadcast to work.

Advertisers & Media Agencies

Buy airtime with the certainty that payment moves only against a proven airing, turning post-campaign verification from a trust exercise into an on-chain query of every booked spot.

Network & Execution Architecture

Whether you are bridging a network's playout and traffic systems or wiring an independent monitoring provider into the feed, Cerulea routes both into one proof-gated record.

Track A: Broadcaster Traffic-System Bridging

For networks on legacy traffic and playout platforms. Booked and as-run events are translated into signed on-chain slot proofs through the API gateway automatically.

Technical Methodology

The legacy timeline reflects broadcast-technology integration benchmarks. Connecting traffic and playout systems, wiring monitoring providers into escrow logic, and building tamper-evident as-run anchoring 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 booking and proof rules into pre-audited WebAssembly binaries and provisions the escrow and notary layers instantly.
