### Builder (Optional)

Post-Gloas fork, validators may optionally act as builders to submit execution payload bids for block inclusion.
This requires registering with builder-specific withdrawal credentials (`BUILDER_WITHDRAWAL_PREFIX`).
Post-Gloas fork, builders are separate non-validating staked actors that submit execution payload bids for block inclusion.
Builders register by depositing with builder-specific withdrawal credentials (`BUILDER_WITHDRAWAL_PREFIX`) and are tracked
in the beacon state's builder registry.

Building:
1. [Fetch ExecutionPayloadBid](#/Validator/getExecutionPayloadBid) from beacon node for the current or next slot's proposer to include.
