Securing the
Cold-Chain Pulse.
In 2025, Usaretailmarket partnered with a major regional cold-storage provider to eliminate document fraud and temperature reporting discrepancies. The challenge was a fragmented legacy system that relied on manual reconciliation at three different border crossings.

Auditability Across 8 Ports
The Implementation Architecture
We deployed a private, permissioned distributed ledger where IoT sensors broadcast encrypted temperature data directly to the chain. This removed the possibility of manual overrides. Every change in "Custody" was recorded with a cryptographic signature, creating an immutable history that auditors could verify in seconds rather than weeks.
"The transition to a decentralized validator model did not just save us time; it standardized our compliance posture across the entire ASEAN trade route."
Constraints & Realities
We had to ensure low-latency performance in environments with intermittent satellite connectivity. By implementing a local edge-node sync protocol, we ensured that data was valid even when ships were offline, syncing to the main ledger as soon as port cellular networks were reached.
