These diagrams show how the Neuro platform is structured — the layers that make up every Neuron, and how Neurons, clients, and services connect across a federated network.

​
The platform stack

Every Neuron hosts the full platform stack. The layers build on each other — each one depends on the ones below it.
LayerWhat it provides
The NeuronThe federated runtime. Handles all communication and interaction across domain boundaries.
Neuro-LedgerDistributed, auditable persistence. Records signatures, state changes, and events.
Legal Identities & Smart ContractsVerified actors and governed agreements tied to real identities.
Payments & Tokenized AssetseDaler payments and Neuro-Feature tokens, built on top of the full stack.

​
The federated network

Neurons are independent nodes operated by different organisations, federated together into one network. Clients connect to the Neuron they are registered on and can interoperate with participants on any other Neuron in the network.

​
How federation works

Neurons connect to each other using XMPP server-to-server (S2S) links — the same protocol used by the broader XMPP network. This means:
  • A contract can be signed by parties registered on different Neurons.
  • A token can be transferred between users on different Neurons.
  • An identity on one Neuron can be verified and trusted by another.
No central coordinator is required. Trust flows through the network based on the relationships between Neurons and the cryptographic signatures on identities and contracts.
