Introducing BuilderNet.

BuilderNet is a decentralized block building network for Ethereum that runs on TEEs and shares MEV & gas fees with users.

An early version of BuilderNet is live today — operated by Flashbots, Beaverbuild, and Nethermind. Public blockchains like Ethereum promise to be the best global platform for finance and innovation.

But the concentration of power in block building today threatens to compromise this vision and Ethereum’s censorship resistance and neutrality.

1/ Introducing gas refunds from Flashbots — the open, permissionless alternative to proprietary orderflow deals.

As of July 8th, gas refunds are available on all transactions sent to Flashbots Protect and Builder. The refund rule is open source and executed securely in TEEs. Many transactions could land on chain just as quickly for a fraction of the cost. But choosing the right gas fee is a headache for users, and these fees can cost applications multi-million $ in revenue per year

Introducing rbuilder – an Ethereum block builder written in Rust with a focus on performance, modularity, and contributor friendliness.

We've been running rbuilder in production at Flashbots for 3 months and are excited to open source it. We're open-sourcing rbuilder because we believe that an efficient and decentralized block building market must be built in the open. It incorporates everything we’ve learned in 2 years since creating the original MEV-Boost builder for the merge.

We’re upgrading Flashbots Protect to make private transactions faster⚡️

You can now connect to more builders through the Protect RPC https://t.co/4GJT9z8i3Mdocs.flashbots.net/flashbots-prot…
Today, all Protect transactions are sent directly to the Flashbots Builder. This guarantees important protections like pre-trade and failed-trade privacy.

But it has a cost.

MEV-Share is a new paradigm for searchers. It unlocks new orderflow, features, and searching strategies — all while keeping transaction data private.

But what does it mean to search on private orderflow? We put together a short guide writings.flashbots.net/searching-on-m… To start, you can find all MEV-Share transactions sent to the Flashbots Matchmaker at mev-share.flashbots.net. This includes transactions that use Flashbots Protect, which is about 3% of traffic on Ethereum mainnet.

MEV-Share beta is live on Ethereum mainnet

collective.flashbots.net/t/announcing-m… TL;DR
1. Users should decide how, when and by who their transactions are executed
2. This lets them internalize their MEV and be included faster on chain
3. Flashbots is launching a beta release of MEV-Share with orderflow sharing to give users more power in the MEV supply chain
