# White Noise

> White Noise is a decentralized, end-to-end encrypted messenger built on the Marmot Protocol, which combines Nostr (decentralized messaging relays), Blossom (encrypted file storage), and MLS (group encryption). It requires no phone number, email, or account to use. It is open-source, non-profit, and community-driven. Funded by And Other Stuff, OpenSats, and the Human Rights Foundation.

White Noise provides forward secrecy and post-compromise security for both direct messages and large groups. Messages are encrypted before reaching Nostr relays, so relay operators cannot read them. Media is encrypted client-side and stored on Blossom servers. The network runs on thousands of independent relays worldwide. Users can self-host relays.

## Building with Marmot

To build a Marmot-compatible client, use the MDK (Rust) or marmot-ts (TypeScript, early stage). The developer guide covers MDK crate structure, Nostr event kinds (443, 444, 445, 10050, 10051), default ciphersuite, identity model, client flow, and MIP status.
