The Rollup Multiverse — Jon Charbonneau

Feature, Not a Bug - Rollups Are L1s (& L2s)

Thank you to Patrick McCorry and Kobi Gurkan for the invaluable feedback and review. Introduction I like rollups so I’m writing another thing, sorry. I’m pretty sure it’s helpful because I’ve gotten a ton of value out of these myself. Just writing it all down and talking to people like Patrick and Kelvin who have amazing mental models has been awesome. There might be a double-digit number of people crazy enough to even want this level of intuitive understanding of these systems, but if you’re one of ‘em hopefully this helps. This time I’ll more directly address why the rollup ≠ bridge rambling
