Blockchain technology provides a major advance for excipient supply chains, assisting in the delivery of unadulterated, source, process and transit verifiable excipients (or APIs and drug products), but does not alleviate the necessity for quality audits. The adoption of blockchain technology should make the process faster and make the transactional record more robust and reliable, however other rate-limiting steps of the excipient supply chain including transit and testing time will remain. In terms of pure speed, blockchain is suited to financial transactions where no physical goods change hands (such as financial instruments and derivatives, stocks, insurance, land-registry, taxation, medical records etc.) but this does not mean that it should be ignored in respect of the advantages it could offer in improving the excipient supply chain.
