A technical deep dive into Fedimint, a federated eCash mint for Bitcoin communities. This workshop starts with a high level overview of federation design, including trust assumptions, guardian roles, Lightning integration, and user roles. It then goes deeper into networking internals and how the peer to peer plus client server stack works in practice.

The session also covers how Iroh can simplify federation setup through direct peer connections without requiring public IPs or domain names, making deployments on platforms like Start9 or Umbrel more practical. If you want to deploy community mints with cleaner operations and better UX, this workshop maps the path.

Recorded live at TABConf 7 in 2025.
