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?

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).

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)
