Did L2 Fragment Ethereum? - With Yuval Rooz, Co-founder & CEO of Canton Network

In this episode of The Defiant Podcast, Camila Russo sits down with Jing Wang to discuss how Optimism is evolving and why the debate over what counts as a “real” Ethereum L2 might be missing the point.Jing argues that the most important question isn’t whether a chain is an L1, L2, or sidechain. It’s whether the architecture actually serves users and real-world use cases.“If it looks like an L1, we’ll build that. If it looks like an L2, we’ll build that.”In the conversation we cover:Why Optimism now sees itself as a network of blockchains (the Superchain)The debate around Ethereum L2 decentralization sparked by Vitalik ButerinWhy institutions are already using decentralized railsWhy ZK proofs are the futureAnd why Jing believes finance inevitably moves on-chainNexo is a premier digital assets wealth platform that helps clients build, manage, and preserve their wealth through advanced interest-generating products, crypto-backed credit, advanced trading tools, and 24/7 client care.

Robinhood is opening the testnet for its Arbitrum-based Ethereum Layer 2. In this episode, we sit down with the fintech’s head of crypto, Johann Kerbrat, to discuss the strategic move to build on Ethereum.
