Migrating to BuilderNet

Flashbots has deprecated its centralized block builders and migrated its orderflow and refunds to BuilderNet, a decentralized block building network intended to be neutral and uncensorable. The project says BuilderNet will make Ethereum more resilient by letting many parties share orderflow and collaborate on building blocks, using verifiable ordering rules and improved privacy techniques. As of December 5, 2024, Flashbots no longer operates centralized block builders on Ethereum, though a few backup instances will remain for extraordinary situations during the BuilderNet alpha period.
