How Crosspass and BitChat Can Strengthen Each Other
July 14, 2025 • Analysis
In regions where internet access is limited or monitored, secure communication tools play an important role. Mesh-network chat apps like BitChat, created by Twitter co-founder Jack Dorsey, and Bridgefy, which gained popularity during the Hong Kong protests, allow users to message over Bluetooth without relying on internet infrastructure. However, these apps lack convenient authentication, leaving users vulnerable to impersonation and man-in-the-middle attacks. Crosspass, developed by Entelecheia, is another tool in the end-to-end encryption space, offering a simple, PIN-based system for securely delivering messages without exposing long cryptographic keys. When combined with mesh apps like BitChat, Crosspass helps users verify each other’s identity—solving a key problem in mesh networks where anyone can pretend to be someone else.
