Introduction

Janus is an authentication and authorization system with the following properties:

• Provable: It's always possible to prove the correctness of a statement. 1 2 3
• Antifragile: As load increases, the system becomes more robust.
• Federated: It's possible to federate multiple instances, thanks to its capability based model.
