"Liquidity Fragmentation Isn't a Technical Problem, It's an Economic One" - Josh Bowen of Astria
About this episode
Most rollups today aren’t sovereign. They rely on a single sequencer, creating a major centralization risk. Josh Bowen, CEO of Astria Labs breaks down how shared sequencing fixes this—eliminating blockchain silos and making rollups more secure and interoperable. Without shared infrastructure, modular blockchains just become fragmented networks. We explore the trade-offs in existing rollup solutions, why DA layers aren’t enough, and how Astria is reshaping the rollup landscape by removing single points of failure. This is how rollups can stay independent while still working together. The future of Ethereum scaling is here.
