At @ETHGlobal Buenos Aires, build the foundations of the Agentic Economy with Nethermind. $10,000. Four bounties. One direction: verifiable, intelligent systems. 🧠 AuditAgent: use AI to spot a real vulnerability in your smart contract and show us how you fixed it. 🤖

When AI systems act in the real world, we’ll need verifiable logic, not blind trust. That’s why connecting roboticists and Ethereum builders matters: shared ground for verifiable intelligence. https://t.co/J30GRLhKSV

@EFDevcon @ethereum The infrastructure is running: → Execution client powering ~30% of the network → AuditAgent finding vulnerabilities pre-deploy → @Ch40sChain creating cryptographic records of agent activity How it connects: https://t.co/0vzK79lqRL AI District, Nov 17–22 to learn more.

Agents that can act are easy. Agents that can prove are useful. At @EFDevcon next week, we're showing how @Ethereum becomes the foundation for verifiable autonomy. Safe execution + cryptographic identity + verification = agents that can prove what they did and why.

Buenos Aires, we’ll see you soon. On Nov 18 (Day 2 of Devconnect), join @worldcoin and Nethermind for The Meeting Spot, a full day of co-working, coffee, and conversations with builders and friends. ☕ Save your spot →

The @ethereum BPO1 fork is live and running smoothly on Nethermind's Hoodi testnet. BPO (Blob Parameter Only) tests validate automated blob capacity increases, which are a key part of the upcoming Fusaka upgrade. Thanks to everyone across the ecosystem for the coordination 🚀

🚨 Nethermind v1.35.2 is out This release replaces v1.35.1 and is mandatory for all node operators. It includes the Ethereum Mainnet Fusaka hard fork config (Osaka, BPO1 & BPO2). Upgrade before Dec 3, 2025 – 9:49:11 PM (UTC) to stay in sync. 🔗

We’re aware of an issue in v1.35.1 that can halt node operation. Please hold off on upgrading until v1.35.2 is live. https://t.co/H3vKeAO24H

@ethereum @marcin_d_s @M25Marek @maceo_eth Gas Benchmarks is now integrated into EELS and EF testing infrastructure, built in collaboration w/ @ChodoKamil, @parithosh_j, @JochemBrouwer96, @0xlouistsai, @CPerezz19, and all client teams. This is how Ethereum scales: empirically, safely, together. https://t.co/V6rErNBGh0

@ethereum @marcin_d_s @M25Marek @maceo_eth At Berlinterop, client teams ran coordinated stress tests under shared parameters. Five days of optimization showed measurable improvement across all implementations. This validated data gave confidence to move from 36M to 45M gas, with the path clear to 60M+ 4/

@ethereum This methodology drove the first performance-to-protocol change: ModExp bottlenecks revealed by benchmarks led to EIP-7883 and coordinated optimizations across all clients. Co-authored by @marcin_d_s @M25Marek @maceo_eth 3/

@ethereum The framework measures worst-case client performance under identical conditions. Same hardware. Same stress tests. Reproducible data. Before any gas limit increase, every implementation must sustain the throughput required without compromising consensus. 2/

What began as a Nethermind experiment is now the methodology @Ethereum uses to validate every gas limit increase. Gas Benchmarks defines how the protocol proves readiness before scaling. 🧵

Nethermind v1.35.1 is live. ⚠️ Mandatory update for mainnet operators ahead of the fork. Release notes: https://t.co/1W0iTwUs19

A small EVM improvement with big performance impact. EIP-7939: Count Leading Zeros (CLZ) opcode, co-authored by @ben_a_adams, lands in Fusaka this December. Making compression, hashing, and ZK proving cheaper and faster. 🔽
