EduRankAI · Public credential ledger
Every certificate, provably real.
Each EduRankAI certificate is a block in a hash chain — its block hash includes the previous block's hash, so tampering with any past record breaks every later one. Each block is signed with Ed25519. Anyone can verify a credential here without trusting us.

The ledger root can additionally be anchored to a public blockchain on a periodic basis for third-party timestamping. The signing private key never leaves EduRankAI's server; only the public key above is published, which is all that is needed to verify any certificate.
