Blockchain authentication system.

In their system there is no credential service provider. Blockchain based academic certificate authentication system overview rujia li yifan wu it innovation interns yxw689 bham ac uk rxl635 bham ac uk o the verification to confirm if the hash value of the merkle tree root is on the blockchain o the verification of the validity of the certificate to avoid the revoked certificate. Signing and decryption keys stay on the device. Blockchain based authentication has some special features.

A blockchain originally block chain is a growing list of records called blocks that are linked using cryptography. Verification and encryption keys are stored on the blockchain.

In part blockchain guarantees data validity by making sure that the data uploaded to it can never be altered in any way shape or form. While onboarding a new user the system generates a lot of keys and addresses to help identify the user later on.

A blockchain identity management system that uses zero knowledge proofs a zero knowledge proof is a method of authentication that through the use of cryptography allows one entity to prove to another entity that they know a certain information or meet a certain requirement without having to disclose any of the actual information that. Each block contains a cryptographic hash of the previous block a timestamp and transaction data generally represented as a merkle tree.
