Cockroaches using apps that send messages without internet? Here is tech behind it

Delhi police are investigating the methods used by protesters in Central Delhi, particularly those associated with the Cockroach Janta Party (CJP), who are using specialized offline messaging applications to communicate despite internet restrictions and mobile network shutdowns. These apps utilize Bluetooth technology to create local networks, allowing communication without 4G, 5G, or Wi-Fi. One example is Bitchat, an app that enables message exchange via Bluetooth without the need for accounts or central servers. The messages are relayed between devices to form a mesh network, which is effective during internet shutdowns. The police are reaching out to app service providers for user information and are employing various investigative methods, including analyzing internet protocol device records and using facial recognition technology. This use of offline messaging apps has been observed in protests globally and during natural disasters.

India orders takedown of Jack Dorsey’s bitcoin-linked messaging app Bitchat

India's Cyber Crime Coordination Centre has ordered GitHub to remove Bitchat, an offline messaging app created by Jack Dorsey, due to its use by anti-government demonstrators in Delhi. The order, issued under Section 79(3)(b) of the IT Act, targets three GitHub repositories linked to Bitchat and requires action within three hours. The app enables anonymous communication without registration, posing challenges for law enforcement regarding lawful interception and investigation. Bitchat is a decentralized messaging tool that uses Bluetooth mesh networks for encrypted communication without internet access, and it also supports offline bitcoin transactions, ensuring continuity during outages or shutdowns.

Verum Messenger Launches Offline Architecture for True Digital Sovereignty

The “People as the Network” architecture is the technical backbone of Verum Messenger’s Offline Mode, which launched on February 2, 2026. It shifts from a Centralized Cloud model to a Decentralized Mesh Network. The system utilizes local hardware, including Bluetooth Low Energy (BLE) and Wi-Fi Direct, allowing devices to connect within a 100-meter range. Messages can "hop" from one device to another to reach recipients beyond direct range, forming an ad-hoc network without a master controller. Local Encryption ensures privacy, as encryption keys are stored on user devices, keeping messages secure during transmission. This architecture is particularly useful in network blackouts, censorship zones, and dense crowds. However, its effectiveness is limited in remote areas with sparse users, where communication relies on the signal strength of individual devices.
