Introducing Zinc+, where we tackle the problem of arithmetizing and proving computations unfriendly to finite fields.

Examples: classic hashes, hash + signature, lattice ops., etc.

We prove 7 SHA-256 compressions followed by the ECDSA MSM with:

Querida comunidad de @NavajaNegra_AB :

Me veo en la obligación de trasladar una situación delicada que afecta directamente a la asociación.

Durante el último año detecté actuaciones que no se alineaban con la naturaleza sin ánimo de lucro de Navaja Negra, concretamente relacionadas con posibles beneficios económicos individuales. Estas cuestiones fueron comunicadas internamente y también trasladadas a los órganos correspondientes.

El pasado día 16, coincidiendo con un viaje en el que me encontraba reuniéndome con patrocinadores y ponentes para futuras ediciones, se me retiró el acceso a las cuentas y canales de la asociación, incluido el correo corporativo. Estos hechos han sido formalmente denunciados.

Ante esta situación, he contactado directamente con los patrocinadores, quienes han mostrado su respaldo al proyecto y a su continuidad bajo los principios que siempre han definido Navaja Negra.

Como presidente, y por responsabilidad, estoy tomando las medidas necesarias para proteger la asociación, su integridad y su comunidad.

Agradezco profundamente el apoyo recibido.

Seguiremos adelante.

Yes, we built it. It's called @Agent4rena_NM.

Two bounty competitions already completed. Third coming soon.

~15 AI security agents are already live on AgentArena, with more coming as security researchers and auditors start building their own agents.

Now we need protocols to start hosting their bounty competitions on AgentArena.

In my view, this is where the future of security is heading.

Nethermind has joined @Mastercard's Crypto Partner Program. We build the Ethereum execution client powering ~30% of the network, and the tokenization and compliant infrastructure for regulated institutions.

[Nethermind Security @NethermindSec]

AuditAgent now supports Solana.

AI-augmented vulnerability detection trained on real audit findings.
Now across Solidity, Cairo, and @Solana.

Raising the security baseline early in development, before manual review begins.

Privacy goes brrrrrr

[Stellar @StellarOrg]

Stellar Private Payments (SPP) is now open sourced!

This means private deposits, transfers and withdrawals on Stellar with ZK proofs and configurable safeguards.

Privacy Builders → Start building!

We just published our work on zkWM at Nethermind Research
zkWM demonstrates how the presence or absence of a watermark can be publicly verified using zero-knowledge proofs, without revealing the watermarking mechanism or sing detection keys

We show sub-second prove+verify times

[Nethermind @Nethermind]

AI watermarking schemes force a choice between public verification & private detection keys.

Nethermind Research introduces zkWM by @Cryptoni0x (Antonio Larriba), using SNARKs to prove watermark presence/absence without revealing detection mechanisms.

305-455ms prove+verify.

[Nethermind @Nethermind]

We're introducing a new benchmark for Ethereum clients.

It replays real mainnet blocks and merged super-blocks to measure real execution throughput.

Initial results show significant performance differences under heavy load, with 𝗡𝗲𝘁𝗵𝗲𝗿𝗺𝗶𝗻𝗱 𝗳𝗮𝘀𝘁𝗲𝘀𝘁 𝗮𝗺𝗼𝗻𝗴 𝗮𝗹𝗹.

zkWatermarking

[Antonio Sabado | Nethermind @ant_sabado]

This is a very interesting take from @dabit3 and I agree with him.

"With AI APIs you're trusting that the provider is running the model they say they are and not messing with outputs, and there's no real way to check."

Our @Nethermind Research team have been developing a zkML-based watermarking technique, with a working implementation. The approach enables cryptographic proofs that the model in use is the authentic, unmodified model, and it provides a verifiable method to detect and prove any tampering or unauthorized alterations.

If this is of interest for the wider Crypto x AI projects and model builders, please reach out and I would be happy to schedule a meeting with my team to discuss further. There are many use cases for LLMs where this capability is especially valuable.

Happy to publish this simple explanation of FRI's security (taking mutual correlated agreement as black box), with fantastic collaborators @nico_mnbt and Benedikt Wagner.

And please do check Nico's superb blogpost for a simple explanation of the proof!

Come to Ethereum London next week! Don’t miss this one!

Join us on Nov 6th (18:30–21:00) for the @ETHLDN meetup, co-hosted by @ETHLDN, @EFetheverywhere, @encodeclub & @nethermind, where Ethereum meets AI & Robotics.

We’re diving into one of the most electrifying frontiers: the intersection of Crypto, AI, and Robotics. 🤖

How do these worlds collide, collaborate, and evolve together on Ethereum? What new possibilities emerge when intelligent agents meet decentralized systems?

🎤 We’re looking for brilliant minds to come on stage, and you could be one of them!

If you’re building at this intersection and want to join the panel or give a lightning talk - tag here, reply, or DM me.

Let’s shape this convergence together.

@cryptodavidw Is it a Game of Life?

[Nethermind @Nethermind]

The most robust Ethereum client just got faster and easier to use.

What’s inside v1.33.0:

· New UI for real-time visibility
· Experimental pruning for disk growth
· Stronger OP Stack peering
· Major performance gains
