Premium add-on
Verification that does not depend on us
Your certificates can carry two independent seals: one anchors them to the Bitcoin blockchain, the other turns them into a digital credential signed with the Open Badges 3.0 standard. Anyone can check them — even without ZERTI.
Proof of existence on Bitcoin
The certificate's digital fingerprint is published on the blockchain. It proves the certificate existed on that date and that no one altered it afterwards. No personal data on the chain.
Signed, portable credential
A cryptographically signed verifiable credential built on 1EdTech's international standard. It passes their official validator and any compatible platform can verify it.
