@open_is_free @Nethermind @open_is_free IMO Judgement. Writing is fast now; deciding what is actually fixable and valuable is the work. Testing is also highly benefited from AI.

[Stavros Vlachakis @svlachakis_]

I think we did our best at @Nethermind concerning the Glamsterdam blocker, brainstormed a lot.

The ultimate fix lands in Hegota. Curious to hear your view!

Please, please try to find holes in it ASAP!

Proud to have driven this one. Busy security week globally, and at @Nethermind we keep adding measures from @AnthropicAI!

[Marek Moraczyński @M25Marek]

Ethereum @Nethermind client has been added to @AnthropicAI's Scanner for the critical open source software.

One would see this and think it is just for Hoodi fork readiness. then you look at performance, and this version is faster than the previous one by around 45%.
Just @Nethermind team doing Nethermind things.

@TheBlockChainer @Nethermind @TheBlockChainer If the sponsor requires the repayment before the user's call, in one atomic batch, a failed repayment also reverts the user's call, so no free ride. The sponsor still loses the gas, but that's by design: work done gets paid, just like a reverted tx.

[Stavros Vlachakis @svlachakis_]

Proud to have co-authored Frame Transactions (EIP-8141). Fee sponsorship and passkeys are coming to Ethereum natively, instead of offchain services!

Already running in the Nethermind client!

[Nethermind @Nethermind]

Nethermind's @svlachakis_ co-authored Frame Transactions (EIP-8141) for the Hegotá upgrade, planned for 2027.

What Frame Transactions change:
An app can pay a user’s fee and get paid back in a stablecoin like USDC. Smart wallets can let users sign with a phone passkey or change their key without moving funds. Wallets do this today with extra offchain services. With Frame Transactions, Ethereum supports this directly.

We’ve built them into the Nethermind Client. See how they work in the video below.

[The Ethereum Economic Zone @etheconomiczone]

An independent prover client running end to end with the EEZ composer is an important step for us.

We’re looking forward to working with @Nethermind on the road to a public testnet with more prover clients!

[Marek Moraczyński @M25Marek]

Performance push was really important in unlocking the 30M gas limit, and now Glamsterdam is coming with another performance unlock.

Now, the @Nethermind team is on a new mission: helping bring post-quantum security to Ethereum.

[Stavros Vlachakis @svlachakis_]

We successfully tested @Nethermind's standalone Rollup0 prover with the @etheconomiczone composer, including L1 proof acceptance and restart/recovery.

One step closer to a public EEZ testnet with multiple prover clients!

Over the past few months, the @Nethermind Client team has been focusing on almost everything BUT performance - authoring, supporting and reviewing EIPs for Glamsterdam, championing Hegota headliner - Frame Transactions, researching state bloat, and much more.

That's not changing - we are still being heavily involved in Ethereum roadmap. But AI has unlocked a whole new level of productivity for us, and we're now pushing hard on several fronts:

1. zk guest program - coming soon to @eth_proofs. Very promising, very performant.
2. RPC refresh - Geth compatibility, major performance improvements, and more. Few projects already got a feeling of what we are shipping - and it is looking very good.
3. Client hardening with AI - Node MCP for users and our custom CoreMCP for developers, helping us ship faster and build a much more stable client.
4. Innovative node optimizations and advanced plugins - unlocking capabilities that could be extremely useful for many projects across the ecosystem, including support for new chains.

And that's just the beginning.

As a "side effect," we've also significantly improved the node's performance at the tip of the chain - before even getting into the Glamsterdam hard fork, which should unlock a whole new level of throughput.

Nethermind is the fastest #Ethereum execution client, and the only one pushing beyond 1.5 GGas/s in p50 block throughput at the tip of the chain.

With the next fork, we expect that ceiling to go even higher - based on Sepolia data, potentially around 3x higher.

And we're definitely not done.

We want to change the rules of the game. The AI-powered tools we've built in-house are giving us enormous leverage, and we're confident this advantage will only grow over time.

Performance is good. 🚀

[Nethermind @Nethermind]

Nethermind Client 2.2.0 is out. For RPC providers: faster responses that use less memory, and faster tracing on Glamsterdam blocks.

Mandatory for Hoodi nodes before the Glamsterdam fork on Oct 26. https://t.co/EZCiQyAZi4

[Łukasz Rozmej @URozmej]

So @nvidia is releasing their new RTX Spark platform to laptops, thus we are adding windows ARM64 support to @Nethermind client! Thx to @0xrubo

[Nethermind @Nethermind]

Tokenizing a fund shouldn't mean a second operation for the same asset. @nitingaur on tokenization's biggest risk.

Bedrock is built for that on public networks: the bank's rules, enforced by its own node, running the Nethermind client.

[Ben {chmark} Adams ⟠ @ben_a_adams]

I have a games industry background, where everything needs to fit within 16.67ms to hit 60fps

That mindset has carried over into other work

So now @Nethermind processes Ethereum mainnet blocks in 16ms at p50, on standard EIP-7870 hardware

@HackingBaseball Fastest part of Ethereum network is C#

[Kamil Chodoła @ChodoKamil]

Already 55% of @Nethermind nodes on #Ethereum mainnet migrated to v2 version!

11% of nodes are on new FlatDb design and number keeps growing!

Consider migration - FlatDb gives a lot of great improvements.

⚠️HalfPath will be deprecated once adoption of Flat will be big enough.

[Kamil Chodoła @ChodoKamil]

"lead and adopt the same changes" in practice.

Less than 12h between @Nethermind PR merged and Reth PR opened.

Hard to be unique in AI times - we expected that :)

What matters is who brings the innovation and that should be higlighted.
