This invention relates to a method 20, 30 of issuing and verifying certificates. The method includes receiving 21, at an NFT assigner 14, a request from an issuer 12 to issue an NFT associated with a certificate. The NFT assigner then validates 22, using a validation module 14.2, the request using cryptographic techniques, ensuring that the request is authentic and authorized. Once the request is validated, the NFT assigner 14 generates 23, using an NFT generator 14.1, a unique and non-interchangeable NFT associated with the certificate. The NFT is then stored or recorded 24 on the blockchain network 16, providing an immutable and transparent record of ownership and authenticity. The NFT assigner 14 then issues 26 the generated NFT to the issuer 12 through the API, providing a standardized and secure way to retrieve the NFT and verify authenticity of the certificate thus preventing fraudulent falsification of degree certificates.

Claims may relate to objective claims, such as an individual's work history or whether an organization has insurance coverage. Trunks and branches may be used to implement a network of cross-ledger claims and endorsements. A first entity (e.g., endorser) may make a claim on a first branch blockchain ledger that is controlled by the first entity. A second entity (e.g., endorser) may review the claim, determine whether it is true, and then produce an endorsement on a second blockchain ledger that is controlled by the second entity. The endorsement may be an encoded version of the claim that cannot be used to reverse-engineer the claim. An endorsement pointer may be recorded to the first branch blockchain ledger that references the endorsement recorded by the second entity to the second blockchain ledger.
