Overview

  • Bitchat is now available on Apple’s App Store, with the Android build accessible only through GitHub ahead of a formal Play Store release.
  • Users have encountered a bug preventing messages between iOS and Android devices, and Jack Dorsey says a fix has been submitted for Apple’s review.
  • Security researcher Alex Radocea identified impersonation vulnerabilities in Bitchat’s protocol, and Dorsey acknowledged there has been no external audit.
  • The open-source app enables end-to-end encrypted, accountless peer-to-peer messaging via Bluetooth mesh networks without requiring internet access.
  • Several fake Bitchat apps have appeared on Google Play, prompting warnings for Android users to download only from the official GitHub repository.
