Bridge Identity is a unique approach to sovereign digital identity that can be applied to a wide range of applications and environments, making it ideal for securely managing and transmitting digital identity. The Bridge Protocol is at the core of the solution, which is simply a peer-to-peer protocol that allows for the secure transmission of portable digital identity. It enables individuals, applications, and devices to send and receive digital identity claims in both on and offline environments. The ability to request and transmit identity in an offline environment opens the potential for real-world applications by removing dependency on Internet connectivity and unpredictable blockchain networks at the point of identity verification. The protocol can easily be implemented in web and mobile applications, blockchain distributed applications, and even in hardware devices.
