Commit-Boost 📻 🕶️ 🦇🔊

We open-sourced libssz, a fast, no_std SSZ library in Rust. It's available on crates.io. EL clients are picking up SSZ. In ethrex we keep dependencies minimal and care a lot about performance, so we built our own: fast for binary SSZ transport, fast and zkVM-friendly for EIP-8025 proving. Faster than Lighthouse on encode and decode. Passes 62,489 consensus spec tests across all forks. Multiple differential fuzz targets against Lighthouse and ssz_rs are running nightly. Pluggable SHA-256 backend so zkVM vendors can use their own accelerators. We're already using it in @ethrex_client and @ethlambda_lean. ere-guests switched and measured a 2x hash_tree_root speedup inside ziskemu. Compiles on RISC-V and thumbv7m out of the box.

Smart Node now supports @Commit_Boost as of v1.19.3. Commit-boost is open-source software that is fully compatible with MEV-Boost protocol, but comes with new features and allows node operators to opt in to commitment systems eg preconfimations.

With nearly 40% of Ethereum's validators using @Commit_Boost , we are proud to have them as a sponsor and bring Blockspace Forum to Cannes. Rumor is they will have 📻 stickers at the event. RSVP: luma.com/blockspaceforum

A few weeks ago I said there was a seismic change in Ethereum's social layer about to happen. It's happening. Multiple big infrastructure players that most users don't know about are starting to collaborate and build together, doubling down on ETH and the Ethereum network. Follow @blockspaceforum to keep up with it. The biggest block builder (@titanbuilderxyz), the biggest relay (@ultrasoundmoney), @ETHGasOfficial, @Commit_Boost (38% network adoption), @QuasarBuilder, @primev_xyz, @nuconstruct, @blocknative, @fabric_ethereum, researchers from the @ethereumfndn, and many others are all coordinating. Many of us realized that they had to team up and work closely together to make our opinions stronger and speed up our ability to deliver. In the last 5 years @class_lambda built many of the most relevant zkVMs and Ethereum L2s. Last year we went all in on @ethereum L1. In a year we built @ethrex_client, one of the fastest production ready execution clients at about 60k lines of code. We're coordinating with big stakers and the MEV pipeline to grow its adoption while also shipping multiple products around it. We're building a new RISC-V zkVM with @alignedlayer and @3miLabs that I think will become a standard for L1 proving and @eth_proofs in the short term. We're working on @leanEthereum by building our own @ethlambda_lean client. We helped develop the @Commit_Boost sidecar that standardizes communication between validators and third party protocols. We're happy to have helped build a critical piece of software that is now running on 38% of the Ethereum network. We also started collaborating with @titanbuilderxyz on different things under @kubimensah's lead. Hopefully soon we'll be working closely with @alextes and @ultrasoundrelay too! There's more I want to share but can't yet. For now I can say that @class_lambda is part of the @blockspaceforum process and I'm very excited about what's coming. Keep an eye on what we will be doing, I promise it's gonna get interesting.

5/12 Ethereum operations reached new scale in 2025: • 300,000+ ETH staked via the 0.1+ ETH staking solution • 110+ ETH MEV captured in February • 130+ ETH MEV captured in a single hour • @Commit_Boost added to improve execution These results reflected years of quiet engineering work behind the scenes.

1/ As we head into the end of the year, I am very excited about 2026 for Ethereum. Several teams have been instrumental in our work on @Commit_Boost, and @everstake_pool is one of them. 🚀📻

Structural issues in the PBS pipeline are slowing, reducing its throughput, impacting UX and most importantly, impacting the robustness of Ethereum!  The answer is not simply, "decentralize the builder", but much deeper. Read more here! ethresear.ch/t/an-observati…

Earlier this year, we upgraded our Ethereum validator stack, Commit-Boost as Blockdaemon’s default proposer-builder separation sidecar. We cover how this improves ETH’s infrastructure and institutional staking outcomes for customers in our blog. 🔗 bit.ly/3MlldFt
