Trading Notes | Proposer-Builder Separation
① Whether to use MEV-Boost is up to each validator. Validators who choose not to use it can also build blocks with a local client.
② Proposer-builder separation (PBS) means assigning “assembling transactions into a block” and “proposing and signing the block” to two different types of participants.
③ If you run your own validator, find out who operates the relays you connect to and what filtering rules they use—don’t focus only on bids.
