Node types

• Identity: links a public key to a name
• Community: identifies a chat room
• Reply: replies to another kind of node

Every node has a "parent" node, so every message forms part of a blockchain/merkle dag.

Programs

• Grove: repository to store old nodes.
• Sprout: protocol for uploading and requesting nodes.
• Relay: forwards requests to other relays and users; is the "server" component in a mesh.
• Client: a tool to help the user interact with relays/sprout.
