## Description

Ethereum co-founder Vitalik Buterin sits down with ETHGlobal’s Kartik Talwar for an in-depth fireside chat at Pragma Waterloo. They cover Ethereum’s scaling roadmap, rollup taxonomy (stage 0 to stage 2), the future of smart contract wallets and ERC-4337, and why decentralization still matters.

Vitalik also shares personal insights on the last 10 years of Ethereum, privacy challenges, social recovery wallets, and the ZuConnect / Zuzalu community experiments. If you're interested in Ethereum L2s, ZK proofs, account abstraction, or building user-friendly decentralized systems, this conversation is packed with thought leadership and actionable insights for developers, builders, and web3 enthusiasts.
