A Distributed File System for Secure P2P Applications

on YouTube ↗45m

" summary

A usable distributed file system exists: the WebNative File System (WNFS) is a content-addressed persistent encrypted forest built atop IPFS as a block store, with a CRDT over encrypted data that lets collaborators edit subdirectories or single files and later merge. It implements a Merkel CHAMP leaf-index, AES-256 block encryption, temporal ratchets for versioned reads and key rotation revocation for removing access, and is shipping JS/wasm and native SDKs used by multiuser file managers, music players, and note-taking apps while IPFS reliability and network latency remain the main operational limits.
