Blockchain certificates' role in society

Here are a few of the merits of moving paper-based certificates onto the blockchain, digitizing and decentralizing them:

Prevent credential fraud

Using hashes and other cryptographic techniques, the validity of our blockchain certificates' content can be evaluated trustlessly.

Last forever yet maintain privacy

Since the hash values of our blockchain certificates are stored on the blockchain, the certificates can always be validated. Since no personal information is stored on the blockchain, privacy is protected in accordance with GDPR standards.

Easy to share

Certificates can be shared by students on any device, or through the Blockcerts mobile wallet, to give prospective employers or schools a standardized, trustworthy certificate containing both machine and human readable information. Printing costs and identity confirmation costs can be cut or eliminated.
