My guest today is Nick Dodson, co-founder and CEO of Fuel.

Fuel is a moduler execution layer that's designed to facilitate performant L2 rollups.

On this episode, Nick and I discuss the history of rollup design, the scaling challenges facing the EVM, and how his years of experience writing Solidity, EVM Assembly, and participating in the EIP process contributed to Fuel's design. We dive into Fuel's underlying UTXOs model, which allows Fuel nodes to validate transactions in parallel across multiple cores simultaneously. Finally we discuss Predicates, which are stateless conditions that can be attached to Fuel transactions, allowing users to pay for gas in ERC20s, SOL, or other coins, and to sign transactions with different eliptic curves like BLS, p256, or EDDSA.

It was great learning more about the exciting technology Fuel has been cooking up for the past few years. I hope you enjoy the show.
