Project Overview
WikiDIDs addresses a fundamental weakness in open knowledge ecosystems such as Wikipedia, academic wikis, and collaborative platforms: readers cannot easily verify who authored content, whether contributors are authentic, or whether content has been manipulated.
To solve this, WikiDIDs introduces a decentralized identity and verifiable publishing framework based on W3C Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). The system integrates directly into the Wiki.js environment and enables:
- DID-based login
- Cryptographically signed contributions
- Instant verification badges for readers
- Role-based review with immutable audit trails
This creates a transparent, privacy-preserving, and tamper-resistant workflow for content creation, review, and publication—supporting the NGI vision of trustworthy, human-centric digital ecosystems.
Methods and approaches
DID + VC Trust Layer Integrated into a Wiki Publishing Platform
WikiDIDs designed and implemented end-to-end workflows for:
- DID login (passwordless, cryptographic authentication)
- Article signing using hashed proofs linked to specific authors
- Verification badge display for transparency
- Role-based approval generating immutable audit trails
These workflows were built into Wiki.js, enabling verified knowledge production while protecting user privacy and data sovereignty.
Interoperability Architecture Aligning EU–US Identity Frameworks
The project produced an extensive interoperability plan aligning:
- eIDAS2, GDPR (EU)
- NIST SP 800-63-3, CCPA (US)
WikiDIDs mapped assurance levels, consent protocols, trust frameworks (EBSI, Kantara), and governance models to enable future cross-border recognition of digital credentials.
The integration blueprint also defined how WikiDIDs connects to external systems like MediaWiki, ensuring extensibility beyond the prototype.
Key Achievements
Functional prototype of DID issuance & verification services (KPI 16).
Complete WikiDIDs architecture covering authentication, signed content, verification flows, and governance (KPI 11).
Demonstration use case with 4 workflows: DID login, content signing, verification badges, and role-based review (KPI 15; page 3).
Cross-border interoperability plan aligning EU–US frameworks (KPI 10).
Integration plan for MediaWiki and external platforms (KPI 12).
Data schemas compliant with W3C standards for DIDs, VCs, and content metadata (KPI 9).
Governance, communication, and brandbook documents establishing the project identity (KPIs 1–4).
Outreach via three webinars and conference participation including CESB Prague 2025 (KPIs 8, 13).
40 interviews and surveys validating user needs, trust gaps, and usability expectations.
Sustainability & business model for post-project expansion (KPI 19).
Impact & Results
Scientific Impact
WikiDIDs demonstrates how decentralized identity can:
- strengthen trust in open knowledge ecosystems,
- provide provenance for digital contributions,
- ensure transparency and integrity in collaborative publishing workflows.
It delivers a replicable architecture for DID-based content governance, contributing foundational knowledge to the decentralized identity and digital commons research community.
Social Impact
The system combats misinformation by providing:
- verified author identity,
- trustworthy attribution,
- transparent moderation and peer review.
It empowers individuals to control their digital identities and contributes to democratic, accountable knowledge creation.
Economic Impact
While no jobs were created directly, the project generated paid opportunities for contributors during testing and established foundations for future pilots within academia and open-knowledge organizations.
EU–US Collaboration
The partnership between Gebchain and SimbaChain was actively maintained through:
- bi-weekly meetings,
- coordinated testing,
- shared repositories,
jointly authored technical frameworks.
This ensures long-term sustainability and positions WikiDIDs as a cross-Atlantic trust infrastructure.
