Lighter’s Ethereum zk-Rollup for Verifiable Perpetual Trading
Summary
The document describes Lighter as an Ethereum-based perpetual futures exchange using a custom zero-knowledge rollup. Its off-chain order book processes orders under price-time priority, while proofs are intended to attest to matching, margin checks, liquidations, and balance changes before Ethereum accepts a new state root. The overview also describes batching, asset custody on Ethereum, and withdrawal or forced-exit mechanisms if the operator stalls or censors activity.
It presents the system as an attempt to combine fast order processing with verifiable execution and self-custody. The text additionally summarizes the LIT token’s proposed governance, staking, incentive, and fee roles, as well as team, funding, and partnership details. These claims are descriptive and largely project-sourced; the article provides no independent benchmarks, security audit findings, or trading performance evidence. Token allocations and utilities are described alongside caveats that some details may be incomplete or subject to future changes.
Key ideas
- Lighter uses an application-specific zero-knowledge rollup to process perpetual futures trades and settle state on Ethereum.
- Its proofs are designed to verify order matching, risk checks, liquidations, and balance updates.
- The order book is described as following deterministic price-time priority rules.
- Ethereum contracts custody assets and track the accepted rollup state, with withdrawal protections described for operator failures.
- LIT is presented as a token for governance, staking, incentives, and potential fee benefits, though details may evolve.
