Ditto Architecture

Ditto is a Deno/TypeScript application comprised of the following parts:

• Web Server (HTTP) - web server built with Hono.
• Mastodon API (/api) - implementation of Mastodon's client-server REST API.
• Nostr Relay (/relay) - NIP-01 relay implementation.
• SQLite - database for storing Nostr events.
• Relay Pool - connection pool to a list of Nostr relays, configured by the Ditto admin.
• Firehose - stream of Nostr events from the Relay Pool to the Pipeline.
• Pipeline - processes all Nostr events that go through Ditto, from all sources.
