EvidenZ is a framework that enables the certification of data on the blockchain, developed by the company Blockchain Certified Data (BCD). Its first use case is BCdiploma, a B2B solution dedicated to universities, training organizations and companies wishing to issue latest-generation digital credentials.

EvidenZ is the world leader in blockchain certification, with 18 months on the market and already some 100 customers in more than 14 countries.

EvidenZ is supplied by the Blockchain Certified Data Token (BCDT), the ERC-20 token of the ecosystem.

Why is it different (and better) than other certification technologies?

Forget about storing documents in digital safes and hash blockchain anchoring!

EvidenZ allows users to work directly from certified data and makes it available in one click. This technological approach is unique: blockchain certification ecosystems using hash anchoring can’t actually be used without their centralized bricks and databases.

In contrast, BCdiploma is a decentralized application: no database of diplomas or certificates. No lock-in effect. A unique guarantee of security, durability and independence. This is possible thanks to the proposed storage technology, allowing institutions to deposit their data on a blockchain in complete autonomy. A revolution that can be applied to many other sectors!

EvidenZ was initially deployed on the Ethereum public blockchain to take advantage of the power of smart contracts and offer maximum security and transparency to the certificates generated on the platform. EvidenZ’s cross-chain capabilities, envisioned right from the design of the framework, are now a reality. Implementations on an ARK bridgechain and on the Binance Smart Chain are already operational and respond to new use cases. The EvidenZ playground keeps growing.

How does EvidenZ respect private data?

Evidenz is designed to make it impossible for third parties to use personal data. In addition, Evidenz includes the right to be forgotten, which allows users to make their data inaccessible whenever they wish, a key element in for compliance with the General Data Protection Regulation (GDPR) that governs the way personal information are processed around the world. This is made possible by a cryptographic algorithm patented by BCD.

What is the benefit of the BCDT?

The BCDT is a utility token that serves as a “gas” in the EvidenZ ecosystem. To issue a certificate, the EvidenZ smart contract must be supplied with BCDT. As the volume of certificates issued with EvidenZ increases, the number of tokens in circulation decreases: BCDT is a deflationary token. The token is thus perfectly aligned with the success of BCdiploma’s commercial activity.
