## What it is
The official technical specification repository for the Farcaster Protocol, a decentralized social networking protocol. It contains Markdown specs, an overview, and a community forum for protocol improvement proposals (FIPs).

## Use cases
- implement a Farcaster hub or client from the spec
- understand how the Farcaster decentralized social protocol works
- propose changes to the Farcaster protocol via FIPs
- build decentralized social apps on Farcaster
- verify message and identity formats used by Farcaster

## When to choose
- you are implementing a Farcaster-compatible hub, client, or tool and need the authoritative spec
- you want to follow or participate in protocol change discussions

## When to avoid
- you want ready-to-use libraries or SDKs rather than a specification
- you need end-user documentation or onboarding guides (see docs.farcaster.xyz instead)

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: social-media, web-development, apis, documentation
- platform: cross-platform
- tags: protocol-specification, decentralized-social, farcaster, specification, open-protocol
