DNAChain

DNAChain provides a cryptographically secured audit trail for DNA specimens, recording each custody event—registration, transfer, processing, and consent updates—as a SHA‑256 hash that is appended to a per‑sample chain. Any alteration after the fact breaks the chain, triggering an integrity alert and allowing a single‑click verification that produces a regulator‑ready PDF report. The system also includes a dynamic consent engine that tracks versioned, scope‑aware participant permissions, issuing expiry alerts and propagating withdrawals across all linked events.

Designed for genomics laboratories, biobanks, contract research organizations, and clinical research institutions, DNAChain offers real‑time global tracking of specimens with dual‑signed transfers and per‑shipment manifests recorded in the same immutable ledger. The platform aligns with compliance frameworks such as SOC 2 Type II, 21 CFR Part 11, HIPAA, GDPR, and GxP, and it presents a live view of the custody lineage that can be inspected instantly for tampering.

Users interact through a command‑line interface or web dashboard to submit custody events, compute deterministic hashes, and verify provenance. The architecture requires no specialist knowledge from donors or lab staff, while delivering a single source of truth for every sample throughout its lifecycle.
