Chorus

Chorus is a nostr relay in development

Development is early and rapid. This is NOT ready to use by any stretch of the imagination.

Plans

High performance due to:

• Rust language
• Asynchronous multithreading
• Memory mapped storage
• Event memory map is almost lock-free (limited to one writer at a time)
• Direct indexing: indices yield the memory offset of the event, not an ID that requires another lookup
• LMDB used for indexes
• In-place zero-copy event field access (does not require deserialization)
• Custom JSON parsing without memory allocation

Simple to deploy due to:

• Being the webserver and the relay for standalone deployment
• TLS optional, to support both standalone and behind-proxy deployment
• Just a single configuration file
• systemd and nginx setups contributed

Flexible nostr usage:

• Can use as personal relay, inbox, DM inbox, etc, with flexible rules around access

Not Planned (yet)

Bitcoin/Lightning integration:

• I don't plan to add this any time soon.
• You won't be able to charge for service.
