White Noise: Anonymous Nostr DMs And Encrypted Group Chat

White Noise, a new privacy-focused messaging app built on Nostr, has launched its alpha v0.1.0 in public beta, adding end-to-end encrypted group chats and direct messages. The app uses the Messaging Layer Security (MLS) protocol, developed by the Internet Engineering Task Force, and introduces an anonymization protocol meant to hide sensitive metadata such as who is sending what to whom. Founder Max Hillebrand, a former contributor to Wasabi Wallet, said existing encrypted apps slow down at scale, with adding 100 people to a group chat slowing encryption to a crawl. The open source alpha invites audits and feedback from the privacy and Bitcoin community.
