From Nodes to Federation: Building Collective Intelligence through Real-Scale Digital Twins

Interoperability not by design, but by construction

Infrastructures speak many languages. They are built across different timelines, technologies, and institutional logics. Nowhere is this more evident than in the Euro-Mediterranean region—a space where agricultural systems, water networks, logistics corridors and energy platforms coexist in geographic proximity but operational disconnection. In this fractured landscape, digitalization is often promised as a unifying solution. Yet when implemented from the top down, it tends to replicate the very fragmentation it seeks to overcome.

What if interoperability were not a prerequisite, but an outcome?

What if, instead of designing abstract standards, we could construct real infrastructures that learn to speak to each other—not by imposition, but through participation?

This is the proposition behind a federated system of Digital Twins, built from the ground up, rooted in physical processes, and scaled through cooperation, not centralization. It is a shift from digital strategy to digital architecture, and from technical alignment to collective operational intelligence.

From isolated twins to federated systems

A Digital Twin—when grounded in a real system—offers more than a simulation. It becomes a way to observe, test, and govern a complex process: a greenhouse optimizing irrigation based on humidity patterns; a port terminal simulating cargo flows under new regulations; a regional water loop modeling resource stress under climate volatility.

But the power of Digital Twins multiplies when they are federated. Not linked through a central server or forced integration, but connected as autonomous agents in a wider ecosystem.

Each node—whether in Sfax, Catania, or Alexandria—can model its own reality while remaining legible to others.

Together, they form a distributed intelligence: not one system, but many systems in relation.

In this federation:

• A PV plant in Tunisia can inform regional energy balancing;
• A port in Sicily can coordinate waste tracking with North African terminals;
• An agro-industrial cluster in Southern Italy can align production planning with water availability from upstream basins.

The infrastructure is the language

Unlike traditional digitalization, which begins with a blueprint and seeks to implement it, the bottom-up approach begins with what exists—and builds interoperability through practice.

Each node constructs its own twin: shaped by its constraints, goals, and capacities. As these twins interact—sharing variables, aligning scenarios, exchanging outputs—a common grammar of cooperation begins to form.

This means:

• interoperability is not enforced but emerges;
• convergence happens through use, not through standardization;
• the system grows by connection, not by expansion.

The infrastructure itself becomes the language of mutual intelligibility—and that language is shaped by operations, not by declarations.

Working at real scale: the only scale that matters

Laboratory simulations and pilot projects have their place. But they often fail to capture the volatility, asymmetry, and coupling of real-world systems. A Digital Twin built on a spreadsheet model is not a twin—it’s a metaphor.

This federation is different: it works on real infrastructures.

It begins with systems that are already in operation, already producing, already under pressure.

And it doesn’t simulate an ideal—it simulates what is happening, or what could happen next.

By embedding Digital Twins in active infrastructures—waste sorting plants, desalination units, smart greenhouses—each node becomes a living site of experimentation, not a showcase. And each federation becomes a distributed testbed for region-wide innovation, training, and emergency preparedness.

Interoperability as a Constructed Commons

In complex and fragmented territories, interoperability cannot be legislated. It must be built.

Not through abstraction, but through interaction.

Not through control, but through cooperation.

A bottom-up federation of Digital Twins shows how this can be done.

By grounding digital systems in real processes, connecting them through shared logic, and allowing intelligence to emerge from the flow of operations, we can move from disconnection to coordination, and from coordination to shared capacity.

This is not simply about making systems work better.

It is about making systems work together—as a new form of territorial commons, where each node is sovereign, and every connection adds intelligence.
