Get ready for Glamsterdam
From Glamsterdam on, your beacon node gets bids from block builders itself, and MEV-Boost becomes optional. Builders are listed in a new version of the validator client's proposer settings, and you choose how much trusted payment to count. Set it up before the fork reaches your network.
