Karl Floersch — CTO of OP Labs (Optimism)

Summary

John Gillan interviews Karl Floersch, co-founder and CTO of OP Labs, about Optimism, the OP Stack, and the coming wave of institutional Layer 2 chains. Karl argues every company and institution will eventually have its own customized chain, making the 'million chains' future a major opportunity for OP Stack and Ethereum. The conversation covers OP Stack adoption by exchanges, Korea's regulatory momentum and Toss's KRW stablecoin pilot, Ethereum L1/L2 symbiosis, OP token value capture, and pricing models. Karl remains bullish on crypto adoption, noting less than 1% of the global financial system is onchain.

  • Karl Floersch explains Optimism's OP Stack and its institutional Layer 2 strategy.
  • He predicts a future of millions of chains, with every company operating its own L2.
  • More than 50 organizations, including major centralized exchanges, have built chains on the OP Stack.
  • Korea is highlighted for regulatory clarity, institutional momentum, and Toss's KRW stablecoin pilot.
  • Karl views Ethereum and Layer 2s as positive-sum and sees Ethereum retaining data availability pricing power.
  • He discusses OP token value capture and Optimism shifting toward fixed-cost pricing models.
  • He stresses that less than 1% of global finance is onchain, leaving a massive growth runway.

Million-chain future powers OP value.
Optimism and the OP Stack are positioned for a future of potentially millions of chains, where every institution, financial firm, exchange, fintech, or company operates its own customized Layer 2. Karl says more than 50 organizations already have OP Stack chains in production, including major centralized exchanges like Coinbase, Kraken, OKX, Upbit, and BitPanda, because the stack is battle-tested, customizable, interoperable, and easy to deploy through OP Enterprise. He argues the OP token is a useful primitive for ecosystem incentives and value capture; pricing is downstream from value added, and Optimism is adding enough value to have pricing power as the model shifts from revenue-share to fixed-cost deals.

Every company will launch an L2.
Karl's core thesis is that every company and institution will eventually have its own chain/Layer 2, similar to every company having a website. Serious businesses want control over their own infrastructure, distribution, monetization, and compliance, and they will not want to put all assets, IP, and distribution on someone else's chain. This creates a large market for Ethereum Layer 2s and interoperable infrastructure; he says there will be a million chains and the world is still early with less than 1% of global finance onchain.

Ethereum benefits from L2 growth.
Ethereum is the neutral Layer 1 optimized for a maximally decentralized audience, and many differentiated Layer 2s are rooted in it. Karl rejects the 'L2s are vampiric to Ethereum' zero-sum view and argues the L1 and L2s can both succeed as the overall pie grows; Ethereum can capture value through data availability pricing power, including setting higher floors, though there is a trade-off between growth and near-term revenue. He says Ethereum is adding value and has network effects and pricing power.
