In this episode, we’re joined by Austin Federa and Mateo Ward to dive into DoubleZero! They explain why bandwidth—not compute—is the real blockchain bottleneck, and how DoubleZero addresses it. We also cover validator economics, token incentives, critiques on DePIN, performance benchmarks, and plans for Solana and beyond.
