OTRv4 is the newest version of the Off-The-Record protocol. It is a protocol where the newest academic research intertwines with real-world implementations. It is also one of the first protocols that comes from the global south which makes the political discussion around protocols an urgency. This newest versions also asks us to revisit our definitions around deniability (online and offline) and how important is it to the world. In this talk we will try to start a discussion around the importance of protocols, its political/moral foundations, the real-world implementation of academic ideas, the importance of securely implementing them, the definition of deniability in the current world and the design of OTRv4.
