The Current State of Layer 2
summary
Rollups deliver a magnitude cheaper and faster experience than L1s today but not the mythical 24,000 TPS; zero-knowledge proofs of the EVM state exist in production and reduce trust assumptions. Major risks are operational complexity, giant ZK circuits, and implementation bugs; sequencers remain centralized in most systems so sequencer centralization and bridges that custody assets effectively hold governance power. Notable deployments include dYdX moving to a Cosmos app chain with ~ $1B daily volume as a live stress test.
