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.[1][2]
The platform 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 authenticity.[1][3]
History
Work on the platform began in late 2017, through the sale of a digital token.[4] and the support of two accelerators (EdJobTech at emlyon business school in France,[5] and Berkeley Blockchain Xcelerator at the University of California, Berkeley.[6][7])
First reported deployments came in May 2020, when Le Monde informatique wrote that the French training organisation Ifocop had used the platform to issue its diplomas as blockchain records.[2][8]
Adoption
The platform has been used by education and certification organisations in several countries, though much of what is publicly documented comes from the adopting bodies themselves.
In 2019, ECampusOntario began a set of micro-credential projects with member institutions.[9] In May 2025 it released a new version presented as a continuation of that earlier work.[10]
In September 2020, the pan-African university network Honoris United Universities adopted the platform for digital diplomas, including a certificate covering professional skills.[11] Member institutions later used it as well, among them MANCOSA in South Africa, which adopted it to protect its certificates against forgery.[12][13]
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.[3][14][15]
In February 2022, ETS Global started issuing digital score reports for the TOEIC English-language test through the platform, in Europe, the Middle East and Africa.[16][17]
In 2023, the Center for Professional Development at Stanford University began issuing digital credentials through the platform.[18] Campus Technology reported that a project carried out with Stanford received a Gold Award at the 1EdTech Consortium's Learning Impact Awards that year.[19]
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.[1][3]
The framework behind the platform, called EvidenZ, uses an ERC-20 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.[4][20][21]
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.[22] 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.[23]
