Graduation Certificate
A permanent, tamper-proof online graduation certificate
Audencia, keen to expand the services it offers to its graduates, wanted to provide them with a permanent, tamper-proof certificate of graduation. With a keen interest in new technologies, it chose blockchain technology to secure the data and provide a framework of trust for the various stakeholders using the system.

This registry on the BCdiploma platform can be viewed directly by following this link.
Each alumni of our programs (Bachelor in Management, Audencia Sciencescom and Grande Ecole programs) over the last 10 years has been assigned a personalized URL that they are free to publish on their CV and professional social networks. Anyone interested in their profile can instantly verify. The following promotions will of course benefit from the same service.
The tool also issues certificates of achievement, diplomas, titles, and training certificates for Executive Education (continuing education).
The layout may vary according to the screen size on which the certificate is consulted, but the information will always be of the same nature.
- At the top right, you can change the language of the certificate (French or English).
- Further down, a link allows you to generate a printable version with a QR code; this QR code, when flashed, opens a browser and points directly to the attestation's blockchain URL.
- At the very bottom, the link to the various proofs of the attestation.
As the operation has a fixed cost per certificate entered in the blockchain, we have concentrated on the diplomas and years that are most in demand. It's rare that after 25 years in the business, you'll still be asked for a diploma certificate; it's more likely to be your CV that speaks for you. Nevertheless, there's nothing to prevent the system from being extended to other programs or to graduates of older graduating classes, either conceptually or structurally.
Like all digital activities, blockchain consumes energy. We chose Etheréum precisely because it consumes 4 times less energy than the Bitcoin blockchain, for example. What's more, without going into the technical details, it is planned that Etheréum will migrate to a "Proof of Stack" model, which is even more energy-efficient than the "Proof of Work" model. Finally, we need to compare the carbon footprint of a traditional model, where graduates request a certificate several times in their life, which must be checked, printed and sent by post, with a model where the certificate is generated only once in the blockchain and can be consulted for life.
The system is perfectly compliant. As this is personal information, the graduate retains control over it. In particular, they can request that their certificates be revoked so that they are no longer accessible.
Many companies and recruitment agencies have well-established processes in which a document has to be supplied in order to be inserted into an EDM (Electronic Document Management). Confirmation in an online directory just doesn't cut it for them. And if we added a PDF file generator to our directory, it would be easy for anyone, with very limited resources, to use it to generate false attestations. On the contrary, by storing the attestation data in the blockchain, it can be made forgery-proof, and the evidence can be exposed without difficulty. Here, blockchain plays the role of a digital notary, a digital mortgage registrar or an online cadastral service. A forger could always try to alter an Audencia diploma certificate, but consulting the evidence in the blockchain would instantly reveal the deception.
