8/ Luganodes runs both @Commit_Boost and MEV-Boost across its fleet. Where MEV-Boost routes all validators under a single beacon node through one relay set, Commit-Boost delivers per-validator relay routing. Each key is directed to its optimal relay. Relay failure is isolated per validator, not fleet-wide.

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

11/ In practice, just over 60% of validators use software that doesn't allow them to express constraints over their blocks.

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.
