Ethereum

One thing I don't understand about based rollups - if L1 nodes become the shared sequencers for rollups, does that imply a large additional amount of compute they have to be capable of? 
Is there some way around needing linearly more hardware per chain you sequence?

Ah ok yeah that makes sense- sequencing as a flavor of searching. Thanks!

Yeah I think it will be like PBS where builders will run powerful nodes for all the rollups + Ethereum. Ethereum validators (the proposers) shouldn't need more compute as they will just accept the highest ETH burn and check a zk proof.

Does every L1 node have to compute every batch?

I thought the OP model was based around spot-checking (and creating massive incentives for finding invalid transactions in the roll-ups).

(this might not be how Base works)

Yeah youre correct, and that's how rollups currently work (incl Base), but there's this idea of 'based rollups' which is a subset/flavor that relies on the L1 protocol to actually sequence the rollup blocks (and thus achieve shared sequencing)
