The app allows users to communicate without WiFi or mobile phone service, extending its typical 100-metre Bluetooth range through a mesh network that relays messages via other users.
Designed for privacy, security, and decentralisation, Bitchat does not require users to share email addresses or phone numbers.
Its innovative approach makes it useful in situations where conventional networks are overloaded or unavailable, such as at crowded events or in areas with no phone signal.
Dorsey highlighted that Bitchat's architecture offers a censorship-resistant platform, making it resilient against state internet restrictions.
