Cold-Chain Integrity Engine

Log every degree.
Settle liability by stage.

Log cold chain conditions across every custody stage on a shared network. Cold-Chain Monitoring and External Data Oracles feed sensor data, and the Quality and Recall Ledger records each excursion against the exact stage where it happened, so liability is clear.

The Foundation

The Execution Mechanics

Turn siloed IoT logs into cross-party proof that pins each temperature breach to a stage.

01.

Cross-Party Condition Log

Record condition on one shared record. Cold-Chain Monitoring writes temperature across every custody stage to a network all parties read, replacing siloed IoT platforms with no shared proof.

02.

Sensor Oracle Feed

Anchor readings to verified sensors. External Data Oracles stream signed temperature data, so a logged condition is measured and attributable rather than manually entered.

03.

Stage-Level Attribution

Pin each breach to a custodian. The Quality and Recall Ledger records every excursion against the exact stage and holder, so liability sits with the party responsible, not the producer by default.

04.

Automatic Excursion Flags

Catch breaches as they happen. A reading outside the safe range flags an excursion immediately, capturing its duration and the stage rather than surfacing a spoiled batch later.

05.

Producer Exoneration

Clear the innocent party. Because condition is logged by stage, a producer whose product left in good condition is cleared when a breach occurred on the logistics leg.

06.

Fast Insurance Settlement

Close claims from evidence. An insurer settles a spoilage claim in hours from the on-chain excursion record, with liability and cause already established.

The Cold-Chain Lifecycle

Follow one prawn batch from vessel through logistics, capturing a breach and settling liability at the retailer.

Smart Contract Anatomy

Cerulea decomposes cold-chain integrity into modular contracts for batch identity, sensor ingestion, excursion attribution, and liability settlement, so a breach is pinned to a stage.

Applicability Across the Spectrum

Cold-chain integrity is a horizontal capability. Here is how producers, logistics, and insurers put one shared record to work.

Producers & Processors

Prove product left in good condition and get cleared when a downstream breach occurs, removing the default blame that siloed logs impose on the source.

Network & Execution Architecture

Whether a logistics provider is bridging a fleet IoT platform or a reefer sensor is reporting directly, Cerulea routes both into one cold-chain record.

Track A: Logistics IoT Bridging

For providers on legacy fleet and IoT platforms. Existing sensor feeds are translated into signed on-chain readings through the API gateway automatically.

Track B: Reefer Sensor Capture

For reefer sensors reporting directly. A signed device feed streams temperature to the shared ledger and flags excursions by stage in real time.

Technical Methodology

The legacy timeline reflects cold-chain IoT integration benchmarks. Wiring sensor feeds, building stage-level excursion attribution, and settling liability across parties 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 condition and liability rules into pre-audited WebAssembly binaries and provisions the shared ledger and sensor oracle layer instantly.
