Indeed, op and arb are pretty shitty for gas fees. I wonder, is it possible to have rollups on tezos with 0 gas fee? In my understanding, L2 should pay gas fee at least to validate its state on layer 1 right? If yes, could we have some very low inflation on l1 like for lb but for l2 gas fee. 0.1 tez per block should be more than enough to run multiple rollups with absolute 0 gas fee (but we may face spam on those l2). Anyone knows?
