BC Diploma platform
A blockchain credentialing platform for educational institutions worldwide
BCdiploma is a credentialing platform used by educational institutions and certification bodies to issue and verify academic and professional credentials, such as diplomas, micro-credentials and Open Badges. It is developed by Blockchain Certified Data, a French company founded in 2017 by Luc Jarry-Lacombe and Vincent Langard. Credentials are recorded on the Ethereum blockchain and presented as web pages, which a third party can open to verify their authenticity.
History:
Work on the platform began in late 2017, funded through the sale of a digital token, as reported by the education technology publication EdSurge. It was supported by two start-up accelerators: the EdJobTech programme run by emlyon business school in France, and the Berkeley Blockchain Xcelerator at the University of California, Berkeley. The project was profiled by L’Etudiant / EducPros in January 2019.
First Deployments:
The first widely reported deployment came in May 2020, when the French professional training organisation Ifocop used the platform to issue its diplomas, as documented by Le Monde Informatique and Centre Inffo.
Adoption in North America:
In 2019, eCampusOntario, a not-for-profit body that supports Ontario’s publicly funded colleges and universities, began a set of micro-credential pilot projects with member institutions. In May 2025 it released an upgraded Digital Credentials Wallet built with the platform. In 2023, the Center for Professional Development at Stanford University began issuing digital credentials through the platform; Campus Technology reported that a project carried out with Stanford received a Gold Award at the 1EdTech Consortium’s Learning Impact Awards that year.
Adoption in Africa:
In September 2020, the pan-African university network Honoris United Universities adopted the platform for digital diplomas, including a certificate covering professional skills. Member institutions later used it as well, including MANCOSA in South Africa, which adopted it to protect its certificates against forgery; this deployment was covered by IT-Online and by the French magazine 01net.
European Partnerships:
In 2021, the platform was chosen to run fr.EBSI, a project led by the University of Lille tied to the European Commission’s European Blockchain Services Infrastructure (EBSI) on verifiable credentials, as documented by Next. Blockchain Certified Data also took part in the EBSI-VECTOR project on verifiable credentials. In February 2022, ETS Global began issuing digital score reports for the TOEIC English-language test through the platform across Europe, the Middle East and Africa.
Integration with Higher Education Software:
In September 2021, the company announced a partnership with the Canadian education technology firm Modern Campus, integrating the platform with the Destiny One course management system used by non-traditional higher education providers in North America, as reported by GovTech.
Technology:
The platform records credentials on the Ethereum blockchain using smart contracts, and keeps the certified data itself in encrypted form, using AES-256-GCM encryption. To meet General Data Protection Regulation (GDPR) requirements such as the right to be forgotten, the design lets the encryption key be deleted, after which the stored data can no longer be read.
EvidenZ Framework and BCDT Token:
The framework behind the platform, called EvidenZ, uses an ERC-20 utility token, BCDT (Blockchain Certified Data Token), on the Ethereum network. The token was issued through an initial coin offering in January 2018 with a fixed supply of 40 million units. Public information on the token can be consulted on CoinDesk and on Etherscan.
Patents:
Blockchain Certified Data holds two patents covering the method the platform uses. US patent 10,715,313, granted in 2020, describes a document certification system that pairs a blockchain with a multi-key encryption scheme, so that certified data can be made unreadable by deleting one of the keys. A French patent published in 2022, FR3121524, covers a related method for storing and sharing certified files on decentralised storage networks such as the InterPlanetary File System.
