Ethereum - Proof of Work and Relay Centralization
In proof of stake, we've moved to this world where we can no longer scale that trust across a more decentralized set of validators. So now to preserve the privacy of blocks that builders are sending through relays to proposers and kind of avoid proposers, MEV stealing, they're being forwarded full blocks of transactions. But if there is censorship at the builder or relay level, there is kind of no way to insert these censored transactions by block proposers. And then simultaneously, while we've managed to kind of decentralize this or optimize for decentralization of validators, now there is this new problem wearing its head which is the centralization of builders.
