I'm starting to worry that based preconfirmations lead to too much centralization pressure, creating a small oligopoly of shared sequencers and provers. Is this really better than centralized sequencers (which can also give preconfirmations)? At least the centralization here is per rollup and not global.

Do you still have the same opinion @dankrad if there are no preconfirmations?

Preconfirmations+composability are what worries me

Right, so based rollups by themselves don't create this problem - it's creating economic games around preconfirmations that do?
