Institutional-Grade Blockchain Solutions, Built to Deliver. Nethermind has long been the foundation for institutional adoption in Web3. We are now making it easier than ever for institutions, enterprises, and crypto-native protocols to engage with our end-to-end blockchain

RT @NethermindSec: Nethermind Security + @arbitrum = 🤝. We are happy that our team was selected as part of the Arbitrum Audit Program, alon….

Today, we celebrate @worldcoin’s remarkable progress in building secure, privacy-first identity solutions for the web3 era. Their commitment to reimagining digital identity continues to set new standards for trust and user empowerment. We’ve been proud to partner with World from.

First blocks processed using the Nethermind execution client on a full @Arbitrum local chain simulation🧪 A major step in our partnership to bring high-performance client diversity to Arbitrum. We are using a modified version of nitro-testnode to initialize a fresh local chain

7/. PerfNet was never meant to be flashy. It’s a quiet tool, built to surface issues early, validate fixes safely, and support Ethereum’s long-term performance. We’ll keep using it, and keep sharing what it helps reveal.

6/. We don’t work in a vacuum. PerfNet scenarios evolve with input from researchers, core devs, and others exploring state growth, client optimization, and execution limits. It’s a team effort, we’re just adding our part.

5/. And the outcomes have been meaningful:. — Smoother average processing under load. — Worst-case scenarios now better understood and mitigated. — Headroom toward higher gas limits is clearer than ever.

4/. We test with real load:. — Inflate state size. — Push gas usage beyond 60M. — Track memory, sync speed, and execution impact. These aren’t theoretical experiments, they reflect what Ethereum could face at scale.

PerfNet is our internal testnet, designed to safely simulate high-stress Ethereum conditions:. — Gas-heavy blocks. — Deep state growth. — Resource-intensive contracts. It lets us observe how clients behave before these scenarios hit mainnet.

2/. Through PerfNet, we’ve:. — Improved worst-case client performance. — Reduced average block processing time. — Helped define a clear path toward higher gas limits (60M–100M+). — Stress-tested edge scenarios in private, safely. Here’s what PerfNet is and why it matters 👇.

1/. Last week, we shared why continuous testing matters. Today, we’re zooming in on PerfNet, our internal testnet for safely stress-testing Ethereum before issues hit mainnet. 🧵

Nethermind Client v1.32.3 is live. ⚡️. A performance-focused release packed with stability, sync, and resilience improvements:.· Archive/full sync memory fixes and improvements.· BlockProcessing stability patch.· Enhanced P2P handling.· RocksDB corruption auto-recovery. 🔗 Learn

We're hiring across engineering, product, and business 🧠. Help us scale real blockchain systems: Infra, audits, ZK, and beyond. · Remote-first.· Global team.· Deep tech, real impact. 🔗

Nethermind is proud to support @boundless_xyz and the launch of The Signal, an open-source ZK consensus client that enables any chain to verify Ethereum’s state cryptographically. This milestone brings Ethereum closer to becoming a universal trust layer: Powering cheaper bridges,.

What gaps, nuances, protocols or features should we include?. · EIP impacts?.· Fair-exchange mechanisms?.· Protocol-specific nuances?. DM or reply, we want this to reflect community input. (4/4).

We’ll publish the SoK as an open-source PDF and keep it aligned with evolving resources, inspired by (3/4).

Why preconfirmations matter:.· Sub-second tx assurances via preconf are critical for UX.· Moving from centralized to decentralized preconf requires deep understanding.· Designs vary widely. Our SoK will clarify definitions, map trade-offs, and outline open questions. (2/4).

🧵 Excited to share we’re working on a Systemization of Knowledge (SoK) for preconfirmations in Ethereum. A collaborative, open-source reference covering theory, designs, critiques, and real-world implementations. Supported by @taikoxyz and an @EF_ESP grant. (1/4)

Our Head of Research @mpfzajac shares Nethermind’s vision for Ethereum: Scaling to billions of users and AI agents using ZK. · Offload heavy compute offchain .· Verify efficiently onchain. This unlocks verifiable, high-throughput systems for the agentic era.

From based rollup templates to L1-L2 composability to AI-aided smart contract audits:. At EthCC[8], we shared what we’ve been researching and building across the stack. 🔗
