## What it is
CYFS (CYberFileSystem) is a Rust-implemented protocol stack that upgrades the Web's basic protocols (TCP/IP+DNS+HTTP) to enable fully decentralized data ownership, publishing, and applications for Web3. It provides the core system for a named-object network where users own their data and devices (OOD) form a decentralized network.

## Use cases
- build decentralized web3 applications
- store data on the internet with user ownership
- publish immutable decentralized content with cyfs:// URLs
- monetize user data as NFTs
- build censorship-resistant apps that can't be shut down
- replace DNS and HTTP with a decentralized naming and transfer protocol

## When to choose
- you want to build fully decentralized Web3 apps with user-owned data
- you need decentralized storage and content publishing outside centralized platforms
- you're experimenting with named-data networking as a Web protocol replacement

## When to avoid
- you need a production-proven mainnet - CYFS is still on testnet
- you want a simple drop-in library rather than a full protocol stack
- you need broad ecosystem SDK support beyond TypeScript
- you require mature tooling and large community support
