A solution would need to reliably scale to internet size while providing a way to establish secure communications through untrusted servers. It became clear that if we combined insights from Certificate Transparency and CONIKS we could build a system with the properties we wanted and more. The result is Key Transparency, which we’re making available as an open-source prototype today.

Key Transparency provides a lookup service for generic records and a public, tamper-proof audit log of all record changes. While being publicly auditable, individual records are only revealed in response to queries for specific IDs.
