We're grateful to see @ethrex_client becoming part of your infrastructure. A meaningful milestone for the project, and another step toward a more diverse and resilient Ethereum.

Great work by @ethrex_client @class_lambda. Amazing work @Nethermind too! Ethereum is scaling.

Lean Ethereum client teams are running interop devnets, hunting for any bugs that show up. As well, teams are testing client optimizations to squeeze as much aggregation throughput as possible from leanVM. To make it more transparent, we made our central devnet Grafana public.

This week's community calls are moving to Monday, July 13th. @ethrex_client goes live at 2:30 PM UTC and @ethlambda_lean at 3:30 PM UTC, back to back on X. Don't miss the updates from both teams.

This week, we closed the Seminar on Coding Theory, Low-Degree Testing, and PIOPs, co-organized with the Cryptography and Distributed Systems Center – UBA. 4 sessions covering linear codes, list-decoding, and modern ZK proof protocols. More than 30 participants joined us throughout the seminar. Proud to launch this kind of initiative in the region. And this is just the beginning. Thanks to Manuel Puebla for an excellent program, and to @Exactas_UBA and @ingenieriauba for the space.

This week we met the Math, Computer Science, and Data Science students from @Exactas_UBA, along with their thesis advisors, who are carrying out their thesis work through our scholarship program. This is the third edition of the program, and we're proud to support public education and research. Thanks to everyone involved in making this initiative possible.

ethrex v19.0.0 fixes the P2P memory leak behind OOM crashes on long-running mainnet nodes. It also clamps snap sync response sizes, tightens EIP-7702 mempool validation, and speeds up zkEVM witness generation. The memory leak is the headline. Connection memory could grow without bounds, so nodes with weeks of uptime would slowly climb until the OOM killer took them down. The fix bounds the connection mailbox, adds lifecycle timeouts, caps peer admissions, and prunes stale connection maps. Thanks to the operators who reported it and helped us chase it down. Also in v19.0.0: - Snap GetAccountRange and GetStorageRanges responses now clamp to the server byte limit - The Engine API rejects forkchoice v3 payload attributes after Amsterdam - Mempool intrinsic-gas and EIP-7702 auth-list validation now match execution, and v1 blob sidecars are accepted pre-Osaka - zkEVM: faster execution witness conversion, with the remaining hash calls routed through the precompile We recommend operators to upgrade. No resync needed.

nice work team @ethrex_client @class_lambda

Congratulations to @ethereuminsti on the announcement. Institutions are deciding the base layer of global finance, and they've been choosing Ethereum. A new team dedicated to accelerate their adoption it's great news for the Ethereum ecosystem. We build technology to help the world adopt Ethereum, and we're all-in.

Yesterday I did an interview with @kubimensah for @therollupco. Thanks @andyyy for hosting. I explained why the PropAMM infrastructure we built with @class_lambda and @gattacahq, already in production and having processed over $300M in less than a month since launch, is bringing velocity to @ethereum. ETH and other assets are now being priced better on Ethereum than on centralized exchanges. Better quoting of assets will bring more volume to Ethereum, more trading, more fees, and make ETH a better asset.

Our happy-path blocks now publish ~0.2s into the slot, down from ~1s. That's within the first slot interval. The change: a block-building optimization from a recent PQ interop call. We prepare blocks one interval earlier, doubling our budget from 0.8s to 1.6s.

ethrex v18.0.0 is out! 🚀 Highlights: - Sync fixes: full-sync wedge, snap-sync restart livelock, FCU on unreachable state now triggers sync instead of idling, plus a storage-range fix for big accounts - Faster crypto: blst for BLS12-381, aws-lc-rs for P256VERIFY - LEVM hot-path wins: 33-STOP bytecode padding, monomorphized opcode dispatch, in-place top-slot mutation - Faster eth_getLogs via header-bloom skipping and bulk receipt reads ℹ️ No resync needed.

I'm very bullish on @ethereum. As I've been saying for a year, the market doesn't understand yet what's going on mostly because it doesn't have all the information, and because crypto is structurally short sighted. Ethereum just needs to keep getting cheaper, safer with post-quantum, faster, and better at quoting prices. Right now the 12s block time is the main bottleneck. With the work we're doing with @gattacahq, @titanbuilderxyz and @class_lambda on the PropAMM world, we'll be able to compete with any centralized player and any fast L1. The work we are doing with @leanEthereum and @eth_proofs is gonna become crucial too long term. ZK will let us increase the gas limit without losing verifiability. Ethereum will win. We just need to double down on a winning, product first mentality without losing our core values.

Since the Enlightenment there has been a tension between advancing productivity, which tends to centralize power and capital, and defending individual freedom and initiative. The first is worried primarily about avoiding chaos, about winning against nature and against competitors. About being organized enough to make the most of the opportunities that exist. The second is worried primarily about avoiding capture: that an individual or a group could use their position to impose their will on the majority. Current political debate is part of this same historical argument, from the East-West division to AI and datacenters. The debate around Ethereum and the Ethereum Foundation is part of it too. Ethereum is an explicit attempt to escape the tradeoff. It is trying to build a global coordination machinery whose control surface is deliberately made unseizable, through decentralization, in-protocol rules, and credible neutrality. I believe the main job of the @ethereumfndn is to defend exactly this. And I believe the market, plagued by short term thinkers, has repeatedly failed to understand how important it is that the EF defends the values it defends. The focus on making Ethereum the most decentralized, secure, and unbiased computing platform is what made Ethereum what it is: the best verifiable, decentralized and unbiased computer in the world. This is what's gonna make Ethereum the global financial backend of the world. That said, I also think the EF, because of its strong mandate and its cypherpunk values, cannot do many of the things the ecosystem needs. This is why I have never seen people leaving the EF as a problem. Not because I wanted people to leave Ethereum, but because in many situations I needed support the EF simply could not give. I have been trying to grow Ethereum in LATAM, Africa, Central Asia, and Europe, and we have made amazing progress, but again and again I needed a counterparty that could sit across the table from governments and central banks. In other cases I needed an organization that could understand what financial institutions require to use Ethereum as their financial backend. The EF was never the right place for any of this to happen. If we want Ethereum to win, censorship resistance and the most decentralized verifiable computer are a must, but they are not enough. I believe the EF has done an amazing job in this regard. But we also need people thinking about how to provide the best quotes in DeFi, how to make ETH the best asset, how to make L2 stacks actually usable, how to meet institutions where they are, and how to bring the next billion users on chain without compromising the values that made Ethereum worth defending in the first place. We need hackers with a product sense that are capable of understanding the market needs and translating them to technical requirements. I believe @rudolf6_, @adietrichs and the rest of the team are some of the most capable people in the world to do this. I'm thankful to them for letting us support them in their new quest. The EF defends the foundation. Someone has to build the rest of the house. I believe @ethlabs_org is doing this. I'm confident more organizations like Ethlabs will appear to keep defending Ethereum in every front possible. @class_lambda will work closely with them to make Ethereum and ETH win. Happy hacking @ethlabs_org!

We are co-organizing the Seminar on Coding Theory, Low-Degree Testing, and PIOPs with the Cryptography and Distributed Systems Research Center, and yesterday we hosted the third session at our office. One more session to go. Building local expertise in applied cryptography through spaces like this is part of our commitment to the development of the field in the region.
