Block CEO and Twitter co-founder Jack Dorsey has launched Beta’s new decentralized peer-to-peer messaging service that runs entirely via Bluetooth.
Jack Dorsey He said his weekends are spent learning “Bluetooth network networks, relays, storage and forward models, message encryption models and a few other things” Introduced Sunday on Bitchat.
Dorsey added that the “Bluetooth Mesh Chat” system had “IRC (Internet Relay Chat) resonance” and returned to the early days of web-based messaging systems in the late 1990s.
his white paper For more detailed information about Bitchat, a decentralized messaging application running over a Bluetooth low-energy (BLE) network network.
“It provides short-lived, encrypted communication without relying on the internet infrastructure, making it resilient to network disruptions and censorship.”
Completely dispersed and private
According to the white paper, the network will be completely decentralized with no central server, account, email address, phone number to register or infrastructure dependencies.
It provides a “short message” that exists only in device memory and is not stored in the central database. There are also End-to-end encryption Additional security layer.
Currently popular messaging applications such as WhatsApp and Messenger are run by social media giants such as Meta, which are centralized, profit-driven companies that use personal and messaging data as products.

Meanwhile, the grid network enables automatic multi-hop message relays, which can set up room-based chats using tag-based group chats and optional password protection. A “Storage and Forward” system caches offline peer messages during a set time period.
April, Cointelegraph Report Some popular social messaging apps may monitor users and introduce personal information and messages.
Bluetooth relay and HOP message
Each device acts as a client and peripheral device, creating a self-organized grid that can jump to distant peers between devices. The system uses a 30-meter Bluetooth range with a bridge node connecting individual clusters.
Messages are encrypted based on whether they are private, in the room or in the broadcast, and the large mail is divided into smaller 500-byte blocks.
There are future plans to enable WiFi messaging, which will increase bandwidth for large messages.
Multiple use cases
The system has several use cases, such as meetings, protests, disaster areas, or any situation where the internet infrastructure is unavailable, unreliable, or distrust.
The paper concluded that Bitchat proved that without the security of centralized infrastructure, private message was possible, and noted:
“By combining Bluetooth mesh networking, end-to-end encryption, and privacy protocols, Bitchat provides resilient communications that work anywhere people gather, regardless of internet availability.”
Dorsey is no stranger to the messaging protocol, and he served as CEO of Twitter while founding the decentralized social messaging platform Bluesky in 2019. Leaving Bruskie’s Board of Directors No explanation in May 2024.
