W3 Alliance

Enabling the next-generation of the web for governments, enterprises and digital ecosystem

For Governments

Sustainable digital sovereignty, cross-border interoperability and digital identity systems

For Enterprises

10% turnover cost savings, elimination of data silos and vendor lock-ins

For Integrators and Platforms

New services built on shared data layer, interoperability and security by design

Why it matters

Data sovereignty by design, not by regulation

Reduction of integration costs and complexity

Elimination of vendor lock-in

Interoperability across systems, organizations and countries

Alignment with European Data Space and Digital Identity initiatives

The structural challenge

The Web 2.0 model has reached its structural limits: the core resource of the data-driven economy remains fragmented and locked inside countless platforms.

This leads to:

01

Fragmented data across hundreds of systems

02

High integration costs

03

Vendor lock-in and limited flexibility

04

Data duplication and inconsistencies

05

Limited interoperability between organizations and countries

Regulation addresses the symptoms. W3DS addresses the root cause.

The Solution
Web 3.0 Data Space (W3DS) introduces a new architecture

Data is separated from platforms, stays at its source, and can be accessed by multiple interoperable services. 

Instead of storing data inside platforms:

  • Each individual, organization or device has its own eVault
  • Platforms access data temporarily, with permission
  • Multiple services can work with the same data
  • Services compete on quality, not data control

We bring together institutions to design and deply this new paradigm

Public institutions and government agencies

Research organizations and universities

System integrators and technology providers

Industry partners across key sectors

Applications

Use cases by audience

Citizen-centric data architecture

Personal and organizational data stays at the source, not in fragmented public registries.

Reduced administrative costs

Shared original data reduces duplication, reconciliation work, and registry maintenance overhead.

Cross-border interoperability

A persistent digital ID linked to the person and their data enables trusted service delivery across borders.

Improved digital identity systems

Aligned with eIDAS and the European Digital Identity framework.

Elimination of data silos

All information systems work with the same and always actual original data instead of maintaining inconsistent copies.

Reduced integration costs

Replace complex point-to-point integrations with one shared interoperable data space.

Freedom to switch vendors

Change systems without losing data, breaking workflows, or triggering costly migrations.

Better data quality and decision-making

Real-time access to consistent original data improves coordination, analytics, and execution.

Access to high-quality, verified data

Build services on trusted original data with clear permissions and cryptographic accountability.

Faster onboarding of users

Users arrive with identity and data already in place – no repetitive registration flows.

New services built on shared data layer

Create interoperable services that work across platforms instead of inside closed ecosystems.

Implementation
W3DS ensures compatibility with existing systems while enabling structural transition
01

W3-Adapters for existing platforms

Synchronize data between eVaults and platform databases without full redesign.

02

Gradual platform-by-platform migration

Avoids significant one-time redesign for large enterprises and government agencies.

03

Integration with legal and regulatory frameworks

Compatible with GDPR, Data Act, and eIDAS throughout the transition.
