Open world foundation models thrive when built on truly open coordination mechanisms. The real test isn't just having decentralized infrastructure—it's whether that infrastructure can coordinate seamlessly across ecosystems. Solana's DePIN ecosystem is proving this concept in practice right now. Projects leveraging Solana's high throughput and low costs are experimenting with decentralized physical infrastructure networks at scale. When you combine open protocols with genuine coordination incentives, you unlock new possibilities for infrastructure innovation. The key question: can these models scale coordination across borders and trust boundaries without sacrificing decentralization?
