[PODCAST] Karel Kubat from Union Labs on Building a Composable, Trust-Minimized Modular Ethereum
Description
Summary
Karel Kubat, CEO of Union, lays out a bold vision for a decentralized coordination layer that can unlock true interoperability in crypto. He breaks down why bridging is still broken, why ZK is more than hype, and why Bitcoin needs to be more than digital gold. From security risks to UX gaps to regulatory pressure, this conversation covers the hard problems and how Union is solving them.
