About proposer-builder separation:
Validators cannot see the specific transactions in a block before signing its header, preventing them from copying builders’ MEV opportunities after seeing the contents.
PBS also introduces new risks: block building is becoming increasingly concentrated in the hands of a few builders, and relays have become another link that requires trust.
