Diving into Arbitrum’s Optimistic Rollup

Episode 179 · May 5th, 2021 · 1 hr 45 secs

About this Episode

This week, Anna and James host Ed Felten and Steven Goldfeder, co-founders of Arbitrum, an Optimistic Rollup project born before the term "Optimistic Rollup" was even coined.

Ed and Steven tell Arbitrum’s story, from its beginnings as a chain-agnostic university project in 2014 to become an Ethereum-based Optimistic L2 Rollup solution based on fraud proofs. They cover Arbitrum’s interactive fraud proofs, how they differ from other solutions like Optimism, and how Arbitrum and the Optimistic Rollup helps Ethereum scale.
