It's 2024, L2s are a critical part of the Ethereum scaling roadmap, and everyone *still* gets Rollups completely wrong. If you think that Optimistic Rollups and ZK Rollups are real things, that Rollups need sequencers to create blocks, or that Rollups need proofs to be secure, you've been completely and utterly bamboozled by the Crypto Twitter intelligentsia. It's time we take back the truth - this is How Rollups *Really* Work.

Stage 5

Sup nerds, I'm Kelvin. I've been working on building L2s in the Optimism universe for the better part of the last six years or so. I also previously did R&D on Plasma, an early model for L2s before Rollups took over. I currently do a variety of things over at OP Labs but generally have a focus on core smart contract development for the OP Stack.
