Identity verification and data management have become pain points of the modern Internet. Almost every application wants to store or verify your personal information, bringing with it the risks of security vulnerabilities and privacy leaks.

This is where MPC multi-party computation comes into play. Instead of consolidating sensitive data on a single server (which is a hacker's target), it's better to change the approach — break the data into multiple encrypted fragments and distribute them across different nodes. Even if a node is attacked, the attacker can only access useless fragments. Complete information will never be exposed at any single location. This is the core logic of decentralized identity management.
