Published in the June edition of the Gaia-X Magazine
The Gaia-X Hub France is pleased to announce the publication of its technical booklet: “Digital Wallets at the Core of Trust in Data Spaces.” This comprehensive resource stems from a highlevel workshop held on October 7, 2025, which brought together key stakeholders to explore the future of identity and sovereignty, and the current state of the art in wallet technologies within the European data ecosystem.
Why Digital Wallets Matter for Gaia-X
In the architecture of data spaces, identity management and compliance are the fundamental pillars ensuring secure data exchanges and participant sovereignty. The booklet explores the paradigm shift towards Self-Sovereign Identity (SSI), a decentralised model that grants users (whether individuals, legal entities, or connected objects) full control over their digital credentials without relying on centralised authorities.
From Theory to Large-Scale Implementation
The publication bridges the gap between theoretical frameworks and industrial reality. It features expert contributions on:
• The SSI Revolution: An exploration of the transition from siloed identity models to user-centric ecosystems, illustrated by the TracIA project for dynamic patient consent in healthcare.
• Regulatory Alignment: A deep dive into the eIDAS v2 regulation and the upcoming European Digital Identity (EUDI) Wallet, which will provide the legally recognised trust services necessary for scaling data spaces across Europe.
• Industrial Use Cases: Concrete feedback on “Object Wallets” for vehicle health logs, consent management, and the modernisation of transport and logistics through the My Hub Pro solution.
This publication brings together diverse expertise from leading industrial and academic actors (Télécom SudParis, Atos Eviden, Docaposte, Orange Business, IN Groupe) who shared their insights and real-world implementations. Gaia-X Hub France is coordinated by Institut MinesTélécom with the support of Cigref. The “Digital Wallets at the Core of Trust in Data Spaces” booklet is now available for download on the Hub France website: https://www.gaia-x-hub.fr/ wp-content/uploads/2026/05/GaiaX_Wallet_ E4.pdf
