Vladimir Novakovski – Lighter: The Orderbook for all of Ethereum (S7E22)

In this episode I’m joined by Vladimir Novakovski, founder and CEO of Lighter, a decentralized crypto exchange. To kick off the conversation, we explore Lighter's three big design choices: it’s built as a custom Layer-2 on Ethereum, it relies on zero-knowledge circuits for proving transactions, and it runs with a private sequencer. Don't worry – if that sounds like gibberish, Vlad explains it all. Each of those decisions comes with trade-offs — but also big potential advantages. We discuss why Ethereum remains the natural home for new rollups, from inheriting its security to tapping into DeFi’s growing composability. We also break down what zk circuits actually are, why they matter for trust and security in a derivatives exchange, and how they’re verified in practice. From there, we tackle the business side: how you bootstrap liquidity in a brand-new DEX, why Lighter went with an unusual fee model and the key lessons learned during an extended private beta. Finally, we zoom out to the bigger picture. What might DeFi look like if composability really takes hold? Could specialized rollups like Lighter become the backbone of an on-chain financial system, rather than just another venue for speculation? Please enjoy my conversation with Vlad Novakovski. 0:00 Introduction and guest Vladimir Novakovsky 1:53 Lighter's design choices and bootstrapping liquidity 3:19 Vladimir's journey and pivot to Lighter 6:55 Security and transparency in DeFi 8:05 Lighter's architecture and Ethereum L2 advantages 15:10 ZK proofs and circuits in Lighter 23:16 Managing state growth and decentralization in L2s 27:52 Trading fairness and sequencer security 34:03 Securing the bridge and liquidity provider pools 39:37 Addressing risks and platform access in liquidity pools 45:20 Long-term liquidity provision and fee model evolution 51:06 Learnings from private beta and DeFi composability 56:04 DeFi's future, Ethereum, and ZK rollups 1:00:03 Personal obsession with chess
