In this episode of FYI – For Your Innovation, ARK's Brett and Lorenzo are joined by Sandeep Nailwal, co-founder of Polygon, to explore the evolving landscape of Ethereum scaling, the role of Layer 2s, and Polygon’s growing importance in Web3 infrastructure. Sandeep unpacks how Polygon transitioned from a sidechain into a comprehensive execution layer, supporting both shared and dedicated compute environments. The discussion spans Polygon's technology roadmap (including the transition to Polygon 2.0), the distinction between sidechains and L2s, and how Polygon’s AggLayer is designed to unify fragmented liquidity across custom blockchains. They also address the competitive dynamics between public blockchains and “corpo chains” like those initiated by Stripe, Circle, and Coinbase—raising questions about credible neutrality, token economics, and long-term adoption paths. Sandeep outlines Polygon's strategy of prioritizing scale before revenue, aiming to build lasting infrastructure in the face of fast-moving innovation.
