>>Even if it was a different server each time, it’s still an extremely centralized topology for that state transition. That doesn't make the network centralized, since the server that acts as the centralized state transitioner will be randomly selected from a very large pool of servers with equal authority. Innovations that Rollups and Sharding further extend the scalability that is achievable with Ethereum's Proof of Stake consensus protocol, mostly by debundling tasks to create modular components, so that the consensus layer has to handle far less load per transaction.
