A new standard to access certified and academic data

Read the white paper

EvidenZ allows to deploy on-chain registers for all types of small-sized data. It’s conceived to allow organisms, institutions and companies to issue data, while respecting regulation concerning personal data (GDPR, and especially the “right to be forgotten”). It offers individuals a free, direct and permanent access to data, thanks to an URL on which everybody can click.

BCDiploma is the first use case of EvidenZ, which is perfectly adapted to certification and issuing of diplomas. EvidenZ is a cost effective, easy-to-implement, Ethereum-based and open source framework.

What’s new with EvidenZ?

All organizations will be able to issue "one click certified" data with a simple DApp.
All individuals will be able to share certified personal data, without having an Ethereum address. EvidenZ invents the "right to be forgotten" on Ethereum.

What’s EvidenZ DNA?

Neither does EvidenZ store documents nor their hash fingerprints, but only encrypted data directly on Ethereum. EvidenZ generates trust by validating the identity of data issuers first. EvidenZ is open source, so that the access to data remains limitless through time.

Why is Evidenz secured?

Only an organism whose identity has been verified can issue data. The EvidenZ cryptographic protocol guarantees the control of the access to data and the “right to be forgotten”. The data stored by EvidenZ cannot be modified or collected, or exploited for commercial purposes.

Smart Identification

An “ID Certificate” is issued, stored and readable by all on Ethereum after validation of the identity and address of the institution.

Smart Identification

Smart Publication

The institution certifies its data thanks to a DApp, which encrypts them, then publishes them on an Ethereum transaction. The DApp generates the decryption keys and the URL through which data are made readable.

Smart Identification

Smart url

In order to consult data, a single click is sufficient. The DApp reconstitutes the decryption key, thanks to the three keys: the graduate key (URL), the persistence key, and the permanent key.
