Building a truly decentralised, peer-to-peer network, based on a built-in identity system, limits the ecosystem’s interoperability with the outside world. Onboarding developers and users to Urbit was only the first hurdle. On-ramping crypto was a whole different & daunting task. Uqbar set out to build an execution layer on top of Urbit, enabling smart contracts, which would ultimately settle, via a ZK rollup, on Starknet.

We were joined by Tim Galebach, founder of Uqbar, to discuss the different design choices involved, from Hoon programming DevEx to a hybrid ZK-optimistic rollup.

Topics discussed in this episode:
- Tim’s background
- Urbit explained
- How Uqbar took shape
- Integrating crypto in the Urbit stack
- Hoon’s usability and DevEx
- AI-enabled Uqbar
- Uqbar interoperability
- Rollup vs. L1 approach for Uqbar
- Hybrid ZK-optimistic rollup
- Getting from programming in Hoon to ZK proofs
- Use cases for Uqbar & Urbit
