for all those saying Lighter is not an L2 on ethereum (fyi which is doing $9B in daily volume) i'll break it down. LIGHTER IS AN ETH L2 THAT POSTS ZK PROOFS + STATE UPDATES TO ETHEREUM. > in Lighter, every batch generates a validity proof. > ethereum verifies the proof and the state transition is guaranteed by L1. > THIS IS A CORE DEFINITION OF ZK-ROLLUP. > Lighter publishes full data availability blobs on ethereum. > all state diffs (accounts, balances, orders, positions) are posted as blobs on L1. > this satisfies Ethereum’s data availability requirement for L2s. so yes, Lighter is an Ethereum L2. and yes, it’s pushing the frontier with zk + blobs, showing how far ethereum can scale at the rollup layer without compromising L1 security.
