Physics doesn't bend to our wishes—you simply cannot run the entire world's financial infrastructure on a single blockchain. That's not pessimism, it's just how reality works.

Here's the catch with L2 solutions though. An asset living on one Layer 2 chain isn't naturally composable with an asset on another L2. They exist in silos. To move value between them, you need intermediaries—solvers to execute transactions, bridges to ferry assets across.

But here's where it gets tricky. Solvers and bridges introduce their own bottlenecks. They add latency, complexity, and potential failure points. The more dependent your ecosystem becomes on these tools, the more you're rebuilding the very centralized infrastructure you were trying to escape.
