LambdaClass

Catch @diego_aligned at zkSummit 14 in Rome on May 7, speaking about “lambda-vm: minimalistic and performant zkVM.” See you there!

We improved signature aggregation performance, a key component for scaling post-quantum Ethereum signatures, achieving a 3× increase in throughput after a series of optimizations and careful profiling. In this post, we cover the key bottlenecks and the changes made.

Here's a peek at our internal devnet, currently finalizing with 2 ethlambda, 1 zeam and 1 gean clients 🚀

Justin (@drakefjustin) is one of the main reasons I love working in Ethereum and why I believe it has a promising future. During @EthCC, I hosted a fireside with him covering Bitcoin, post-quantum security, @LeanEthereum, @eth_proofs / ZK, Ethereum transaction rails, block building, MEV, and a few other fun topics. Hope you enjoy it as much as I did. Thanks @blockspaceforum for the space to explore so many interesting topics.

Ethlambda Community Call x.com/i/broadcasts/1…

Ethrex Community Call x.com/i/broadcasts/1…

Tomorrow we’re hosting two Community Calls live on X. @ethrex_client at 2:30 PM UTC will cover the latest release and key updates. @ethlambda_lean at 3:30 PM UTC will share progress and what’s coming next. Join us live for a full update from both teams.

Ethrex v10.0.0 is out! Amsterdam fork preparation, execution and storage perf, a new P2P stack, snap sync hardening, L2 proving upgrades, zkEVM progress, node UX.

Appreciate the feature by @ready4merge. Glad to be part of Meet the Devs series. We had the chance to go deeper into our approach, the current state of things, and where we see meaningful progress happening. You can find the full podcast below.

i believe most things will go down even more and almost every team will disappear from crypto but a very small minority. @class_lambda will be one of them. bitcoin, ethereum, stablecoins. pre hack comment:

We're launching our first seminar in collaboration with the Cryptography and Distributed Systems Center: Coding Theory, Low-Degree Testing and PIOPs. 4 in-person sessions, every two weeks, May through July. Buenos Aires, rotating venues across @ingenieriauba, @Exactas_UBA and LambdaClass HQ.

Ethlambda keeps sailing at full speed. @leanEthereum is the future. Merged devnet-4 changes to main (deprecating devnet-3), added new devnet-4 metrics, and updated our Docker image. We continue running multi-client devnets and now have one finalizing with ethlambda, zeam, ream, grandine, and lantern. We also merged an external contribution removing an unnecessary clone. Thanks for the PR! Next: continue devnet 4 interop debugging 🔥

We've integrated @zksync's Airbender as a new proving backend for @ethrex_client on @eth_proofs! The average proving time is ~40s with a single GPU, achieving 14s in some blocks! These are our fastest zkVM proving times to date, and there's still much room for improvement. Thanks to the @zksync team for the great work on Airbender.

New blog post! After covering LMD-GHOST in our previous write-up, we now move to the second half of consensus: finality. How does the protocol decide when a block is truly permanent and cannot be reorged? This post walks through 3SF-mini as implemented by @ethlambda_lean.
