nips

NIPs NIPs stand for Nostr Implementation Possibilities. They exist to document what may be implemented by Nostr-compatible relay and client software. NIPs listed here are not a protocol checklist. Nothing forces any software to implement any NIP. Each app picks the subset relevant to its use case. Don't implement something just because it exists in this repo. Other standards and NIPs may exist outside this repository (e.g. as pull requests) and may already be deployed in the wild -- they should also be considered for implementation.
