Twitter Co-Founder Jack Dorsey Unveils 'Bitchat' Bluetooth-Based Messaging App
Jack Dorsey, the co-founder of Twitter (now X), has launched a new decentralized messaging app called Bitchat, which allows users to communicate via Bluetooth without requiring internet or cellular networks.
The app leverages Bluetooth Low Energy (BLE) and mesh networking technology to create device-to-device encrypted communication, enabling messages to hop between nearby users even in the absence of central infrastructure.
'Bitchat addresses the need for private, resilient communication that doesn't depend on centralized systems,' Dorsey wrote in a post on GitHub, where the open-source foundation of the project is being hosted.
Unlike traditional messaging apps, Bitchat requires no user accounts, no phone numbers, and no cloud servers. It is designed for offline peer-to-peer messaging within a 300-meter range, significantly more than similar apps like Bridgefy, which typically max out at around 100 meters.
Using mesh networking, Bitchat allows messages to be relayed through multiple devices, extending communication far beyond the typical Bluetooth range. It also offers advanced privacy features, including:
The app is currently available in beta testing via Apple's TestFlight platform, but the testing limit of 10,000 users has already been reached. Dorsey noted that the app is undergoing review in preparation for a broader public release.
The launch comes amid increasing global interest in decentralized communication tools, especially in regions facing internet shutdowns, surveillance, or censorship. Similar tools like Bridgefy and Briar have gained popularity among protest movements and users seeking secure, anonymous messaging.
Bitchat builds on these concepts but aims to provide greater range, improved reliability, and no compromise on privacy. Future updates may include support for Wi-Fi Direct, allowing for even faster and longer-range communication without central infrastructure.
Dorsey has long advocated for open protocols and decentralization. His new app aligns with that philosophy, offering users a way to communicate completely outside the control of governments, corporations, or internet providers.
'This is not just about messaging. It's about digital sovereignty,' Dorsey said in his GitHub post.

EgyptAir Cargo Transports Giant Marine Loading Arms to Support Regasification Units
Taarek Refaat EgyptAir Cargo has successfully received two Antonov AN-124 aircraft at Cairo International Airport to transport two massive shipping arms, key components of floating storage regasification units (FSRU), in a pivotal move to bolster Egypt's energy infrastructure. These units are critical for the country's ongoing efforts to secure its energy needs, with the parts being delivered to the UGDC quay at Damietta Port. The Massive shipping arms, also known as Marine Loading Arms (MLAs), are indeed key components of Floating Storage Regasification Units (FSRUs). This operation is part of a broader national strategy aimed at enhancing Egypt's energy capacity and ensuring stable supply chains for the country's growing demand for liquefied natural gas (LNG). The FSRU units will play a crucial role in LNG storage and regasification, allowing Egypt to import natural gas more efficiently, process it, and distribute it for domestic and international markets. The shipment of these specialized components signifies a major step in the country's efforts to diversify and expand its energy resources. The floating storage and regasification units (FSRUs) will be installed at the UGDC facility in Damietta, one of Egypt's most strategic natural gas terminals. These units are designed to receive, store, and transform LNG into a vaporized state for transportation through the national gas pipeline network, facilitating energy imports and optimizing storage capacity. "These large and complex components are integral to our ability to ensure energy security for Egypt in the long term," stated an official from EgyptAir Cargo. "By leveraging the world's largest cargo aircraft, we are not only ensuring the safe delivery of these components but also demonstrating our commitment to supporting national infrastructure projects." Strategic Importance of the UGDC Project The UGDC terminal at Damietta Port holds strategic importance in Egypt's LNG infrastructure. The new FSRU units will not only enhance Egypt's capacity to process and store LNG but also reinforce the country's role as a key player in the global energy market. The initiative is part of a larger effort to develop Egypt's natural gas reserves and ensure the country remains self-sufficient in its energy needs while also maintaining its position as a significant exporter of energy. read more CBE: Deposits in Local Currency Hit EGP 5.25 Trillion Morocco Plans to Spend $1 Billion to Mitigate Drought Effect Gov't Approves Final Version of State Ownership Policy Document Egypt's Economy Expected to Grow 5% by the end of 2022/23- Minister Qatar Agrees to Supply Germany with LNG for 15 Years Business Oil Prices Descend amid Anticipation of Additional US Strategic Petroleum Reserves Business Suez Canal Records $704 Million, Historically Highest Monthly Revenue Business Egypt's Stock Exchange Earns EGP 4.9 Billion on Tuesday Business Wheat delivery season commences on April 15 News Israeli-Linked Hadassah Clinic in Moscow Treats Wounded Iranian IRGC Fighters News China Launches Largest Ever Aircraft Carrier Sports Former Al Zamalek Player Ibrahim Shika Passes away after Long Battle with Cancer Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt Business Fear & Greed Index Plummets to Lowest Level Ever Recorded amid Global Trade War News "Tensions Escalate: Iran Probes Allegations of Indian Tech Collaboration with Israeli Intelligence" News Flights suspended at Port Sudan Airport after Drone Attacks Videos & Features Video: Trending Lifestyle TikToker Valeria Márquez Shot Dead during Live Stream Arts & Culture Hawass Foundation Launches 1st Course to Teach Ancient Egyptian Language
