The fully open-source Pubky protocol only decentralizes where it matters: identity and data. Identity is a public key the user owns. Data lives on a homeserver the user chooses and can migrate at will. Everything else — data presentation, the UI layer — stays in the hands of the application provider and optimizes for a slick user experience.

This 30-minute talk is an introduction to both the concepts and the technology as well as a starting point for building.

We'll cover:
- A closer look at PKARR (Public Key Addressable Resource Records), the protocol Pubky uses for decentralized discovery — built on top of Mainline DHT and used by a growing set of decentralized projects for self-sovereign name resolution: mapping a public key to wherever its data, services, or endpoints actually live, without DNS or central registries.
- How identity, hosting, and discovery fit together end to end: from key generation through DHT lookup to homeserver hosting
- What's already running on the Pubky stack
- How to start building your own Pubky app today: Entry points, examples, and understanding the most important concepts

The goal is to leave the room inspired by a different angle on decentralizing the web. Design choices, working concepts, and ideas worth borrowing into your own projects, whether or not Pubky ends up in your stack.
