I've been looking at Ethereum's move toward scaling through rollups, and one design choice stands out: Ethereum increasingly treats its base layer as a settlement and security layer rather than the place where every transaction must execute.

That separation is powerful because execution can move to specialized rollups while Ethereum remains responsible for ordering, data availability, and final settlement. It creates room for much higher throughput without abandoning the security assumptions of the main chain.

But the trade-off is complexity. Users now interact across multiple execution environments, liquidity can fragment, and bridges introduce additional assumptions that did not exist in a single-chain model.

To me, the bigger question is whether Ethereum can make this modular architecture feel like one coherent network rather than a collection of separate systems. How much complexity can users realistically tolerate before scalability starts hurting usability?#AI agents test hash functions $ETH $AIN
