What Is COA Chain?
COA Chain is building a protocol layer for verified Certificates of Analysis—connecting certificates, businesses, laboratories, websites, products, batches, and blockchain records through one controlled verification path.
Traditional COAs are commonly distributed as PDFs, images, or generic QR-code links. Those files and links can be copied, altered, reused, or displayed by a seller or website that was never authorized to use them.
COA Chain protects more than the document. It creates a registered relationship between the certificate, the verified organization, the relevant product or batch, the authorized website or participant, and the live status of the record.

Who Is DPS?
DPS is an established provider of certified communications, blockchain records, digital certificates, and independently verifiable proof tied to documents, transactions, and real-world events.
DPS provides the infrastructure and experience behind COA Chain. Its systems have been used to certify communications, preserve evidence, connect digital records to physical delivery events, and create blockchain-backed records that organizations can independently verify.
By building COA Chain on DPS infrastructure, the network begins with proven certificate and verification capabilities rather than relying on a stand-alone QR-code page or an unconnected document repository.

About COA Chain FAQ
Common Questions About the Network.
Clear answers about what COA Chain does, how DPS supports it, and what verification does—and does not—establish.
Is COA Chain a testing laboratory?
No. COA Chain does not perform laboratory testing. It protects and verifies the registered certificate, the identity of the participating organization or issuer, the relationships connected to the record, and the record's current status.
What does “powered by DPS” mean?
It means COA Chain uses DPS digital certificate, blockchain, identity, and real-world event infrastructure as the foundation for registration, protected records, verification, and independently verifiable evidence.
Does a COA Chain record prove that a product is safe or compliant?
No. A verified record can confirm the registered document, issuer, organization, product or batch relationship, and current status. It does not independently prove scientific accuracy, product safety, manufacturing quality, or regulatory compliance.
What is a COA.1?
A COA.1 is the digital fingerprint and independently verifiable record of an original Certificate of Analysis that has been registered through the COA Chain and DPS hybrid verification system.
Who is COA Chain designed for?
The initial network is designed for laboratories, peptide sellers and resellers, supplement brands and retailers, compounding pharmacies, manufacturers, and private-label suppliers that need to protect COAs and verify authorized use.
