Fireside Chat with Optimism Co Founders Jing Wang and Mark Tyneway at ETHConf

Thu, Jul 2, 2026, 12:00 AM

In this fireside chat, Optimism co-founders Mark Tyneway and Jing Wang take the stage to address rumors of Optimism's demise, defend the L2 thesis, and preview what's shipping next. They open by joking about Jing's intense treasury management discipline (Mark slept in a tent on the roof of the office for two years) confirming Optimism has years of runway. On the broader L2 sentiment, they reject the narrative that L2s are interested in forking away to become L1s, with Jing explaining that despite frustration with shipping speed inside the EF, Optimism continues to choose Ethereum L1 as its DA because of the properties it offers. They both express strong support for the controversial CROPS roadmap (censorship resistance, capture resistance, open source, privacy, security), arguing the backlash was more about communication than content. Mark and Jing share lessons from Optimism's own struggles with decentralized development during the token pump era, which made every idea feel like a good one. They remerged all companies back into one entity and have shipped more in the last six months than the previous two and a half years combined. They argue Ethereum needs quantifiable success metrics to unify the community, and float the idea of building the largest anonymity set in crypto larger than Zcash. The conversation pivots to enterprise demand for L2s, with Jing explaining their sequencer policy work as the strongest form of compliance: institutions can stake tokens for top of block access, halt trading of equity tokens at the sequencer level across all DeFi protocols simultaneously, and avoid concerns about sanctioned validators processing their transactions. They preview the long awaited reduction of withdrawal windows from 7 days to 1 day, work with privacy partners on private contracts and transfers, and confirm Optimism is hiring with new feature announcements every two weeks. 00:00 Introduction 00:11 Addressing Rumors That Optimism Is Dead 00:40 Treasury Discipline and the Tent on the Roof 01:10 L2s Forking Away to Become L1s 01:37 Why Optimism Stays on Ethereum L1 02:10 Supporting the Controversial CROPS Roadmap 02:38 What CROPS Actually Stands For 03:11 Communication Was the Problem, Not the Content 03:42 Optimism's Own Struggles with Decentralized Development 04:08 Remerging Into One Company 04:27 Gelatinous Cheeks and Growing Up in Crypto 05:01 Why Zcash Gets Love for the Same Roadmap 05:30 Ethereum Needs Quantifiable Success Metrics 06:05 ETH as Money vs Bitcoin 06:35 Building the Largest Anonymity Set in Crypto 07:00 Institutions Still Prefer Ethereum for Trustlessness 07:23 L2 Pedantry vs Real UX Impact 07:55 Sequencer Policies as the Strongest Form of Compliance 08:39 Trading Halts Across All DeFi Protocols at Once 09:39 Why L1 Will Never Match L2 Customization 10:58 Why a Single Sequencer Is a Superpower 11:31 Avoiding Sanctioned Validators on Your Network 12:03 Smart Contract Logic as Sequencer Policy 12:29 Reducing the Withdrawal Window From 7 Days to 1 12:55 From Hoodies to Suits 13:17 Closing: Optimism Is Not Dead _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHConf 2026* ETHConf is a 3 day event for founders, industry leaders, and builders who are excited about the possibilities of building on top of Ethereum.
