Jack Dorsey pushes away from the offline chat Bitchat, Decentralization communication White Paper exposed

New York's power outage unexpectedly highlights the gap in communication resilience, Jack Dorsey launched the offline application Bitchat, using Bluetooth Mesh to build a network and encrypt transmission, which has become a new focus of policy and market attention (Synopsis: Jack Dorsey shouts Bitcoin "delete Satoshi": personality cult affects the development of BTC, it is time to change the smallest unit Satoshi) (Background supplement: Twitter founder Jack Dorsey is Satoshi?

Supporting their communication is Jack Dorsey's newly released decentralized application Bitchat. The tool doesn't rely on Wi-Fi or mobile networks to keep information flowing even when the city is in the dark, highlighting how resilient infrastructure is becoming a new topic in financial markets. Bluetooth Mesh and end-to-end encryption support "disconnected chat" Bitchat uses Bluetooth low energy (BLE) Mesh technology to build a temporary network, a single point of 30 meters, through multi-hop extended distance. Each enabling device acts as both a client and a repeater, enabling anyone to relay messages without a traditional base station. The protocol adopts 128-bit AES-CCM end-to-end encryption and defaults to the "transient message" mode; The system also automatically injects garbled cover traffic and cuts the content into 500-byte fragments to reduce the risk of traffic detection. Bitchat does not require an account or phone number, greatly improving anonymity. Jack Dorsey points out in the white paper that all nodes can operate independently, in contrast to WhatsApp, Signal and other models that must connect to servers. The Trump administration's 2025 "Infrastructure Security First" plan makes maintaining the operation of critical systems a national security priority. Offline, censorship-resistant communication solutions like Bitchat gain strategic value: they can keep in touch with financial transactions, emergency disaster relief, and even social movements when the internet is out. The islands of information that emerged during the 2024 wildfires in Hawaii are precisely where such technologies can step in. Investors used to measure communication services by the size of users, but now they are focusing on network resilience and decentralization. Compared with centralized platforms such as Meta and Google, the emergence of Bitchat has caused the market to re-evaluate the value of the basic layer of communication. Multiple scenarios and unsolved problems In remote mines, offshore drilling platforms, or music festivals without network, Bitchat can quickly set up temporary networks. Companies extending this technology to exchanges, energy facilities, or large factories can also establish private channels isolated from public networks. However, Bluetooth's limited range, device power consumption, and business model remain challenges. Dorsey mentioned Bitchat with "IRC vibes" and the concept of "store and forward" on the X platform, saying: "This practice allows messages to be forwarded even offline, which is a continuation of the spirit of the open network." Whether to add Wi-Fi Mesh to improve bandwidth and coverage in the future will determine whether the product can go out of the niche. From Square's payments, to the Bitcoin ecosystem, to Bitchat's offline network, Jack Dorsey is pushing the idea of decentralization to a more fundamental level. At the intersection of policy needs, market focus, and technological maturity, decentralized communications are upgrading from geek experiments to new options for financial and social infrastructure. When the next power outage or disaster strikes, the ability to quickly network and keep the message is the most convincing test of this technology.
