Data Sovereignty: The New Standard for the Sustainability of Digital Credentials

What is data sovereignty applied to credentials?

Data sovereignty is the inalienable right for an institution to maintain exclusive control over its certification registries, ensuring that data is neither stored in a proprietary database nor exploited by a third-party provider.
To understand sovereignty, one must distinguish between data hosting and data governance.

• The centralized storage trap: Data is stored in the provider’s database. If, for any reason, the provider no longer allows access to this database, the credentials are no longer accessible.
• The decentralized response: BCdiploma uses smart contracts and decentralized storage to automate issuance, following a DApp logic. Compliance with standards, such as Open Badges 3.0 (OBv3), guarantees interoperability with ecosystems and platforms, for example in the context of international recruitment.

In the centralized model, your data is hosted “at someone else’s.” If this provider changes their pricing, modifies their general terms, or ceases operations, access to your own diplomas and micro-credentials is threatened. Sovereignty reverses this relationship.

How to avoid the “vendor lock-in effect” and guarantee the sustainability of credentials?

To avoid “vendor lock-in,” some providers try to rely on international standards, such as W3C Verifiable Credentials or EBSI. However, to date, no universally recognized implementation is in production, limiting the desired effect and the independence ultimately provided to institutions.

The major risk for a university or a government is proprietary lock-in. If your credentials depend on a private database, you become “hostages” of the vendor. To address this challenge, BCdiploma uses a decentralized architecture and guarantees that issued credentials can be read and verified without any time limit.

Why is data portability the key to GDPR compliance?

Data portability, enshrined in Article 20 of the GDPR, mandates that users can retrieve their data in a structured and commonly used format to transfer it to another provider.
Sovereignty cannot exist without interoperability. BCdiploma relies on 1EdTech standards and allows export in a universal format. This is crucial for data portability.
A micro-credential issued by a Canadian university must be readable by a recruiter in Europe or a government system in Singapore without the latter needing a BCdiploma account.

Comparison: Sovereignty vs. Proprietary Model

Feature	Centralized Storage Value	Sovereign Credential (BCdiploma)
Data Ownership	The provider (Private database)	The institution & the learner
Access after contract	Often revoked or subject to fees	Guaranteed for life
Lock-in Risk	Very high	None (interoperable standards)
GDPR Compliance	Depends on the provider’s DPA	Native (Privacy by design)

Why Governments and Universities Choose “Sovereign Credentials”

Higher education and regulated sectors are adopting sovereign certification to eliminate the operational risk associated with a provider’s failure and to meet security requirements concerning education data. For a government agency or a professional body, the disappearance of a vendor cannot mean the disappearance of evidence of skills. By choosing a solution without proprietary lock-in, these institutions guarantee the continuity of public service.

Thus, for example, BCdiploma has been the technical provider for the Canadian government agency eCampusOntario and for the certifier AFNOR Certification since 2019. Since 2022, BCdiploma has also equipped the Government of French Polynesia for official documents issued by the Polynesian Directorate of Maritime Affairs.

Here is how sovereign certification responds to major digital infrastructure crises:

• Scenario A: Disappearance of the provider.
  • Classic risk: Servers shut down, and diploma URL links return a 404 error.
  • Sovereign Response: An open-source service ensures business continuity, with credentials that remain available and verifiable.
• Scenario B: Cyberattack and ransomware.
  • Classic risk: The central database is encrypted by a hacker; diplomas become inaccessible, either temporarily or permanently.
  • Sovereign Response: Decentralized and immutable storage guarantees long-term data security. Neither the data nor the evidence of authenticity can be modified.

Conclusion: Establishing the New Standard for Sovereign Trust

The transition to sovereign credentials is much more than a simple technical upgrade; it is a fundamental shift in how society preserves value and trust. For public institutions, professional bodies, and universities, the priority is no longer just to “go digital,” but to ensure the sustainability of these digital proofs for decades to come.

By adopting an architecture without proprietary lock-in, institutions are making a proactive choice in favor of independence. They are moving away from proprietary data silos toward a future where the diploma is a permanent and portable asset, owned by the learner and verifiable thanks to the blockchain.

BCdiploma stands as a leading player in “sovereign credentials,” a vital standard for higher education and regulated environments. It does not just provide a service; the solution offer the reference implementation for sovereign trust. In a world of sometimes ephemeral SaaS providers, choosing sovereignty is the only way to ensure the long-term sustainability of your institution’s most precious assets: its data and its reputation.
