Jack Dorsey launches Bitchat, a Bluetooth-based messaging platform
2025/07/07 03:15Twitter founder Jack Dorsey has published the white paper for Bitchat, a decentralized messaging platform operating entirely over Bluetooth.
The app is designed to work without internet access, relying instead on Bluetooth Low Energy (BLE) mesh networks for peer-to-peer communication.
What is Bitchat?
Bitchat is a privacy-first chat platform built on a store-and-forward architecture using BLE.
Its goal is to offer censorship-resistant communication that remains functional even during internet outages or infrastructure failures.
Bitchat operates across BLE mesh networks, allowing users to communicate securely within physical range. According to its white paper, each device serves as a client and server, relaying messages between users in a decentralized fashion.
This multi-hop design expands communication beyond the direct Bluetooth range, making it possible to reach offline or distant devices through nearby nodes.
Bitchat uses a custom BLE mesh protocol that lets devices scan for others within a 30-meter radius using a shared service UUID. Once discovered, they connect and create temporary mesh hubs. Messages are encrypted end-to-end and exist only in device memory by default, ensuring security and ephemerality.
Meanwhile, the platform also features a store-and-forward system.
Bitchat caches messages sent to temporarily offline devices, with tiered retention windows: 12 hours for regular peers and indefinite storage for selected favorites. Once those devices reconnect to the mesh, they automatically retrieve any stored messages.
Bitchat’s structure eliminates the need for phone numbers, emails, or permanent identifiers. It offers room-based messaging for group chats, complete with optional password protection.
Communication is encrypted at multiple levels, and digital signatures are used to authenticate messages.
The whitepaper concluded:
“bitchat demonstrates that secure, private messaging is possible without centralized infrastructure. By combining Bluetooth mesh networking, end-to-end encryption, and privacy-preserving protocols, bitchat provides resilient communication that works anywhere people gather, regardless of internet availability.”

Ken Griffin, founder of Citadel, believes there are three major potential pitfalls in AI computing power investment: GPUs and airlines share similar structures—once supply exceeds demand, marginal prices will plummet; the high rental premium for outdated GPUs is unsustainable, and investment firms' 7-to-9-year depreciation models are facing revaluation; enterprise AI spending has shifted from trial and error to precise ROI calculations, aiming to save costs wherever possible, which conflicts with the massive capital expenditures of tech giants.

A Reuters survey shows that most economists expect the Bank of Japan to raise interest rates to 1.50% in December, following rate hikes in June and September and continuing a rapid quarterly hike pace in this tightening cycle—which initially saw the Bank of Japan increase rates only once a year.
AI infrastructure enters the "calculation stage"! The market no longer only looks at capital expenditure; cash flow and investment returns have become new challenges.
The overall sentiment in the market toward AI investment trading is undergoing a broader shift, and investors may be scrutinizing ambitious expansion plans and their paths to profitability more rigorously.
