GMP and CMC Data Integrity — Blockchain for Pharmaceutical Manufacturers — GMP and CMC Data Integrity
Pharmaceutical manufacturers face unique blockchain applications beyond DSCSA distribution compliance: GMP data integrity, CMC documentation, and clinical supply chain management.
Attributable: Every blockchain transaction is signed by the submitting party's cryptographic key. Who submitted what, when, is mathematically verifiable. Contemporaneous: Blockchain timestamps are immutable and cannot be backdated. Original: Blockchain records cannot be altered after submission. Accurate: Cryptographic...

CMC is the section of drug applications covering manufacturing process, specifications, and controls. FDA requires any changes to CMC be reported (prior approval supplement, changes being effected, or annual report depending on change impact). Blockchain application: Version-controlled CMC documentation with cryptograp...

No — blockchain is not a LIMS replacement. It is a layer on top of your LIMS providing immutable audit trail. Your LIMS stores the detailed test data; the blockchain records that a specific test result (identified by hash) was submitted by a specific analyst at a specific time. The two systems are complementary.
