The network
Macula
A federated relay mesh over QUIC — DHT routing, membership and identity. Nodes connect across Europe with no single provider and automatic failover.
A European Research Commons
BEAM Campus
Open infrastructure for sovereign, distributed and evolutionary AI — built on the BEAM, running across a federation of small machines owned by no one and open to everyone.

What it is
AI that runs on many small machines — not one big cloud.
BEAM Campus is an open, European effort to build the infrastructure for distributed and evolutionary AI: a federated mesh of small, low-power nodes that anyone can join, with no central owner. The tools are open source and run on the BEAM — the Erlang virtual machine behind decades of resilient, highly concurrent, distributed systems.
The stack
Four open pieces, one substrate
Each layer stands on its own and is open source. Together they let populations of agents live, migrate and evolve across the mesh.
The data
ReckonDB
A BEAM-native event store with zero external dependencies — distributed event sourcing on Raft, with a full CQRS framework. Published on hex.pm.
The platform
Hecate
A sovereign application platform: a mesh-connected daemon plus a desktop app and an app store for extensions.
The evolution
Faber
The evolutionary layer — neuroevolution (topology-and-weight-evolving neural networks) on the BEAM, built to evolve populations across the mesh.
Why a mesh
The science and the substrate agree
Evolutionary methods evaluate many candidate solutions independently, generation after generation. There is no single enormous model to shard and no gradient to synchronise — just a population and its fitness. That work spreads naturally across many small, unreliable, geographically scattered machines: exactly what a federated mesh is good at, and exactly what a hyperscale cloud is not.
Get involved
Three ways to take part
Run a node
Contribute compute to the mesh and help the federation grow. Every node that joins makes the network stronger and more resilient.

The core libraries are open source and on hex.pm. Integrate Macula or ReckonDB in your own Erlang/Elixir project, or dig into how it works.
