Supply chain tracking is the end-to-end recording of a product’s movement, custody, and condition as it passes through producers, logistics, and retailers. Blockchain-based approaches anchor these events to an immutable, shared ledger so that participants can verify provenance and detect tampering without trusting a single intermediary. It enables traceability for food safety, anti-counterfeiting, and regulatory compliance.

- Tracking systems attach identifiers such as QR codes, NFC tags, or IoT sensors to physical items and log each handoff, location, and environmental reading as a verifiable event. Recording these events on a distributed ledger gives all parties a tamper-evident, shared source of truth, which is valuable where trust between participants is low. Applications span pharmaceutical cold chains, luxury-goods authentication, and sustainability reporting where independently auditable provenance is required.
