Welcome back to The Gwart Show! Today, Alex B from Ark Labs joins us to talk about the Ark protocol and Arkade implementation - a Bitcoin layer 2 that uses transaction batching and virtual UTXOs to scale Bitcoin beyond Lightning. We explore how Ark competes with roll-ups, enables Bitcoin capital markets, and could transform Lightning's UX while maintaining self-custody. Alex explains the technical innovations, use cases from payments to lending, and why this could be Bitcoin's answer to Ethereum's scaling solutions.
