Someone raised a fascinating point about Lighter's operational costs as a zk-rollup. Worth digging into.

Every rollup has to settle data on Ethereum's base layer—that's non-negotiable. But here's the catch: when L1 gas fees explode, it directly eats into Layer 2 profit margins. We're talking potential squeeze scenarios.

For zk-based solutions like Lighter, those settlement costs aren't trivial. They're posting proofs and transaction batches constantly. If Ethereum's fee market goes parabolic again (remember 2021?), smaller rollups might feel the pinch harder than established players with better capital buffers.

Anyone tracking these metrics long-term? The sustainability math gets sketchy when base layer costs 10x overnight.
