Domains

This page introduces Domains (or Synchronizers) in Canton and explains how they are created and configured in Catalyst. Canton is a network composed of multiple domains, each operating under its own rules, governance, and set of participants. Each domain functions as an independent sub-network that participates in the wider Canton Network.

What is a Domain/ Synchronizer?

In a composed solution, each domain is a sub-network. A Participant Node connects to one or more Domains, enabling transactions that span Domains.

For more information about Participant nodes, see Participants.
