Language: English

Gosling is a Tor onionservice-based protocol and Rust reference-implementation which allows developers to build privacy-preserving p2p applications with the following properties:
- persistent authenticated peer identity
- end-to-end encrypted
- anonymity
- metadata resistance
- decentralisation
- real-time communication

This talk will go over the complexities involved in combining all of these properties (with a focus on metadata resistance) and describe how Gosling solves these problems.
