From Theory to Real Infrastructure: How Libelium Materializes the EuroStack

At Libelium, we have understood for two decades that digital sovereignty is like owning a house: you can digitize every room, but if you don’t have control over the physical structure and the veracity of the data circulating within it, you don’t own your home.

More than 80% of digital technologies and strategic infrastructure in Europe are imported. This structural dependence is not just a competitiveness issue; it is a critical vulnerability for our economy, security, and autonomy.

For years, the debate on digital sovereignty in Europe has oscillated between regulation and theoretical aspiration. However, the landscape has changed dramatically: with the EuroStack initiative and a public investment of €300 billion, Europe has made it clear that sovereignty is no longer a legal debate, but an operational industrial priority.

But how does this European Union blueprint translate into the day-to-day reality of a public or private organization?

Libelium, 20 years building European datacracy

Therefore, we have published our new Whitepaper: “EuroStack in action: Libelium’s architecture cementing European digital sovereignty”.

This document is not a theoretical analysis. It is a technical guide based on our real-world experience with highly complex projects, such as the Alhambra Living Lab, where we have demonstrated that it is already possible to deploy a sovereign, auditable, and high-performance digital infrastructure.

What will you find in this report?

In this whitepaper, we break down how our architecture aligns with the EuroStack, enabling organizations to adopt native technical sovereignty without bureaucratic hurdles:

The Alhambra Living Lab transcends basic environmental monitoring to establish a high-availability edge digital twin structured under the EuroStack layers:

Robust Acquisition and Connectivity Layer (SmartEurope IoT): The project deploys Libelium IoT devices and communication gateways non-invasively throughout the monument site. The system captures real-time critical variables including atmospheric pollution, microclimate, vibrations, visitor flows, water quality, noise, or air quality, among other parameters.
Cloud Infrastructure Layer (SovereignCloud): Libelium implements the iris360 deployment over OVHcloud for the Alhambra Living Lab, ensuring data residency within European Union borders and immunity to extraterritorial laws. This choice, aligned with decentralized and interoperable cloud guidelines, is backed by the high-level ENS certification (ENS Alto), completely protecting the iris360 platform against unauthorized cross-border access and complying with stringent European regulatory standards.
Artificial Intelligence and Language Models Layer (SovereignAI): Data analytics are processed natively and independently within European territory. The project applies Libelium’s Causal AI engines directly at the edge for predictive heritage conservation and automated biodiversity inventory. Additionally, the Living Lab deploys advanced Generative AI capabilities and sovereign Large Language Models (LLMs) like ALIA or Mistral for Dynamic Multilingual Tourist Adaptation. These models run on local servers under strict public administration control, avoiding the transmission of sensitive data to third-party infrastructures that compromise institutional sovereignty.
Data Assurance Layer (DataCommons): Every variable captured across the monumental site is automatically submitted to Libelium’s veracity audit engine. The system verifies device calibration, filters physical noise anomalies, and cryptographically signs each data packet at the source. Consequently, the Alhambra’s data is ready for interoperable integration into European Data Spaces, providing managers with a highly reliable scientific public repository free from captive foreign licenses.

The time is now

The window of opportunity to consolidate this sovereign infrastructure under the EuroStack initiative is limited. The organizations that lead this deployment now will be the ones setting the standards of trust and resilience for the next decade.

If you lead an organization that manages critical assets and are looking for technology that guarantees autonomy, security, and compliance, this is the document that defines your roadmap.
