We've got 25 minutes to go as deep as we can possibly go into the architecture of modern (modular) rollups. We'll be looking at the theory behind the components of these rollups and we'll be grounding this theory in the concrete components of the OP Stack.
Cmon, where do you think we are, 2019? It's 2022 y'all, and rollups are getting really, really cool.
This talk will cover a lot of technical detail in a short amount of time, so come prepared and chug a lot of coffee beforehand.

Superb talk. Helped me clear up a lot of the fundamentals behind how Optimism works. Thanks Kevin!

[@GoddamnAxl]

nice talk, but it would be miles better if he could show a concrete example of the journey of a transaction happening on OP, the way it goes through each layer, and how it's settled eventually on L1

Would be really convincing after Bedrock and Cannon get shipped first. Else OP Stack would NOT work in the next 12 months...

no idea whether he really knows what he is talking about. Maybe he is not aware of any challenges
