Cold Chain on PYRAX
Cold chain moves temperature-sensitive pharmaceuticals, food, and biologics where a single excursion can spoil an entire shipment and trigger regulatory recall. Proving an unbroken temperature history across handoffs is the core challenge. PYRAX anchors continuous sensor data as verifiable attestations and auto-settles claims when the chain is broken.

What's broken today
How PYRAX transforms it
Concrete network elements mapped to this business.
IoT device identity and micro-payments
Each temperature and humidity logger holds a cryptographic identity and signs readings on-chain, so the sensor stream is provably from that device and cannot be retroactively edited.
GhostDAG high-throughput ledger
500k-TPS GhostDAG ingests dense per-minute readings from thousands of reefers and shippers concurrently, keeping a complete, unsampled temperature history.
On-chain escrow with automated claims
A spoilage insurance contract holds premium in escrow and auto-pays the shipper the instant a signed reading breaches the agreed threshold, closing claims in minutes.
Viewing keys for regulators
An FDA or EMA inspector receives a scoped viewing key to review one lot's full cold-chain history for GDP/GMP compliance without accessing unrelated shipments.
eth_getProof verifiable custody
Each handoff commits a proof of the temperature range held during that leg, so liability for an excursion is assigned to the exact custodian responsible.
