Lighter · interactive mechanism simulation

Orders hit an offchain central limit order book on a purpose-built zk-rollup; matches batch into zk-SNARK proofs that settle back to Ethereum L1. Retail pays zero fees — HFT flow subsidizes the rollup.

Illustrative simulation. Defaults mirror the researched Lighter mechanism (zero retail fees, tiered HFT fees, zk-SNARK-proven matches batched to Ethereum L1) but order sizes, timing, and batch cadence are randomized for visualization — not live onchain data. Part of The Onchain Experiment Atlas.
