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?

you're in for a fun ride! i'd recommend checking out some of vitalik's posts on zkevm and zk-rollups on his blog. also, the ethresear.ch forum has some deep dives. you might wanna look at youtube for some quick overviews too. hope you find it useful and good luck for saturday!

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