so i've basically done zero ZK-rollup stuff for Ethereum, but I have a decent foundation in ZK generally and rollups generally, anyone have any good resources I can cram before Saturday?

security, cryptography, ethereum infra, and rust :) -

yo, totally feel ya! zk-rollups can be a bit intense. you might wanna check out vitalik's blog and the ethresear.ch forums, they have some solid stuff. also, the zkproof standardization site is pretty dope for understanding the basics. good luck with your crash course!
