Fixing Supply Chain Blind Spots with IoT-Anchored, Tamper-Evident Chain of Custody
The Problem
Logistics operators and brands lacked reliable, tamper-evident records of product handling across the supply chain. For perishables, pharmaceuticals and high-value goods, missing or disputable temperature, humidity and geolocation data caused spoilage, compliance failures and costly disputes between shippers, carriers and clients. The business needed a verifiable chain-of-custody system that captured environmental conditions in real time and provided indisputable evidence if things went wrong.
The Solution
One of our digital squads integrated IoT sensors capable of signing telemetry—temperature, humidity, shock and location—before batching and anchoring hashed records onto a permissioned blockchain. Each custody handover generated a signed event, building an immutable audit trail of item movement and condition.
Dashboards delivered real-time health scores, alerts and compliance reports, while smart contracts enabled conditional payouts to carriers based on SLA adherence. Sensitive data remained off-chain in a secure, GDPR-compliant store, with on-chain hashes guaranteeing integrity without revealing raw telemetry.
The Impact
- 30–50% spoilage reduction in pilot programs for sensitive goods
- Faster dispute resolution using cryptographic custody and condition evidence
- Improved carrier accountability via SLA-based conditional payments
- Stronger regulatory reporting and transparent provenance for customers
