The post Jack Dorsey Unveils Decentralized Bluetooth Mesh Network Bitchat appeared on BitcoinEthereumNews.com.

Block CEO and Twitter co-founder Jack Dorsey has launched the beta version of a new decentralized peer-to-peer messaging service that runs entirely over Bluetooth.  Jack Dorsey said his weekend was spent learning about “Bluetooth mesh networks, relays, store and forward models, message encryption models, and a few other things” as he introduced Bitchat on X on Sunday.  The “Bluetooth mesh chat” system has “IRC [Internet Relay Chat] vibes,” Dorsey added, harking back to the early days of web-based messaging systems in the late 1990s.  His white paper goes into more detail about Bitchat, which is a decentralized messaging application that operates over Bluetooth Low Energy (BLE) mesh networks. “It provides ephemeral, encrypted communication without relying on internet infrastructure, making it resilient to network outages and censorship.” Bitchat architecture overview.

There is also end-to-end encryption for an extra layer of security.  Current popular messaging applications such as WhatsApp and Messenger are run by social media giants such as Meta, which are centralized, profit-driven corporations that use personal and message data as a product.  Related: Jack Dorsey’s Block to bring Bitcoin payments to Square by 2026 Meanwhile, mesh networking enables automatic multi-hop message relaying, and room-based chat can be set up with hashtag-named group chats and optional password protection. A “store-and-forward” system caches messages for offline peers for set time periods.  In April, Cointelegraph reported that some popular social messaging apps could be spying on users, hoovering up personal information and messages.  Bluetooth relays to hop messages  Each device acts…
