BBChain | Trustworthy Distributed Document Verification System


An Efficient Trustworthy Distributed Document Verification System.

The perfect combinations of Blockchain and Biometrics


Only the required information to prove the authenticity of an identity or a document is stored on-chain.


All data are encrypted and are over the users' control using selective disclosure mechanisms and zero-knowledge proofs.


The actions of the institutions are linked with users' biometric information and ensured by the blockchain.


Trusted Digital Degree Certificates

The project aims to build a privacy-preserving and fault-tolerant public database of digitally authenticated documents, allowing that academic degree certificates to be issued and verified from any place in the world with a high degree of trust.

The institutions' processes are designed as smart contracts, providing trust in the execution and transparency of operations.

Biometric identification

Uses biometrics to prove the ownership of the user's identity.
