Block building must be made decentralized, uncensorable, and neutral. To accelerate decentralization in block building, Flashbots has deprecated our centralized block builders and migrated our orderflow and refunds to BuilderNet.

BuilderNet will make Ethereum more resilient by introducing a neutral way for many parties to share orderflow and collaborate in building blocks. It will also create better user experiences by providing a fair and equal platform to trade, and using verifiable ordering rules and improved privacy techniques to keep users safe.

As of December 5 2024, Flashbots no longer operates centralized block builders on Ethereum. A few instances will remain as backups to ensure continuity of service in extraordinary situations during the BuilderNet alpha period.

We invite the community to join us in developing BuilderNet, and to accelerate decentralization and neutrality in block building.

An open and efficient block building ecosystem is essential to Ethereum. In order to catalyze further innovation and collaboration in block building, Flashbots has open sourced rbuilder, our latest and most performant block builder written in Rust, and designed to work with Reth.

We believe that sharing the responsibility and benefits of advancing block building creates a positive sum game for all Ethereum stakeholders. rbuilder is designed to be developed and stewarded by the community, and open sourcing it will accelerate this future.

We encourage developers to contribute to rbuilder, all teams to develop their builders in the open, and the community to only trust builders who follow the norms of transparency and free software.

In this post, we preview the SUAVE Centauri release defined in the November 2022 roadmap in the Future of MEV. SUAVE Centauri consists of two parts: A privacy-aware orderflow auction (“OFA”), which we released with mev-share’s beta; and a SUAVE Devnet. This post aims to explain, at a high level, several key ideas that will help understand SUAVE and Flashbots more broadly. Moreover, we invite the community to experiment alongside us with the upcoming devnet launch detailed in the post.
