Introducing Zinc 🪨: Succinct Arguments with Small Arithmetization Overheads from IOPs of Proximity to the Integers (eprint.iacr.org/2025/316)

With Julian Sutherland in Cannes at the Provable 🦁 event at ETHDenver 🏔🦬🦄, representing the Nethermind Security Formal Verification team. Come talk to us!

Nethermind Security has developed the most complete formal model of the EVM execution layer. 🚀❤️‍🔥 This work strengthens the security of Ethereum, providing a foundation for formal verification of execution clients and #zkVMs. 1/

Introducing R0VM 2.0. The zkVM built for the real-time era.

big congrats to RISC Zero doing incredible work for the zk ecosystem. our team has nothing but great things to say about them - our formal verification team at Nethermind Security, led by Julian Sutherland in Cannes, previously collaborated with Risc Zero to build a framework for verifying Zirgen

We just started the 6th edition of #FMBC at ETAPS Conferences (now on other platforms) with a keynote from Julian Sutherland in Cannes which will talk about his experience in "Bringing the power of Interactive Theorem Proving to web3"

We just started the last technical session of #FMBC with a talk of franck cassez which presents his work on "ByteSpector: A Verifying Disassembler for EVM Bytecode"

We are delighted to announce that we have been awarded a grant from the Ethereum Foundation to advance formal verification of zk circuits! 🦾 1/

Another day, another grant! 🔥 Nethermind has received a grant from Ethereum Foundation to formally model the FRI protocol in Lean and draft a blueprint for formal verification of its security guarantees. 1/

We’re attending Zero Knowledge Summit 13 in Toronto today! Looking forward to diving into the latest zero-knowledge research, use cases, and cryptographic primitives. DM Nethermind’s Head of Formal Verification, Julian Sutherland in Cannes, to connect and chat all things zk, including our

Congrats to Nethermind’s Julian Sutherland in Cannes, who was invited to speak at FMBC25 - the talk went brilliantly! In “Bringing the Power of Interactive Theorem Proving to web3,” he discussed how Nethermind leveraged Lean’s proof assistant to build an infrastructure for scalable reasoning about

The Nethermind Security Formal Verification team, led by Petar Maksimović | Nethermind and in collaboration with Succinct, has completed a two-week engagement that demonstrated the feasibility of formal verification of SP1 zk-circuits using Lean, and has verified the correctness of the SP1

Amazing work by Petar Maksimović | Nethermind and Succinct!

It was a great pleasure to work with Uma Roy, John Guibas, and Tamir Hemo on building a proof-of-concept framework for formal verification of SP1 zk chips! Looking forward to our next collaboration!

We’re using Lean to formally verify SP1’s correctness in collaboration with Nethermind, experts in formal methods and ZK security.

👏 Huge congrats to the INTMAX Hub team on the launch of their beta testnet - working towards bringing fast, private payments to Ethereum! Excited to see what's ahead.

🔊 AMA Announcement We're teaming up with Nethermind for a special session: INTMAX × Privacy Mining: Opportunity & Visions 🗓️ Date: June 18, 2025 |1:00 PM UTC 📍 Live on: INTMAX Hub X Space Speakers: - Julian Sutherland (Julian Sutherland) – Head of Formal Verification, Nethermind -

Cool to see #LeanLang used as part of the verification chain in SymCrypt via Aeneas!

The Nethermind Security Formal Verification team, with support from the Ethereum Foundation through the 2024 ZK Grants Round, has developed Halva: an infrastructure for formal verification of Halo2 zk circuits in Lean. We used Halva to uncover a critical bug in a real-world Scroll

At Nethermind Security, we’re building infrastructure for formal verification of real-world zkVMs. We’ve applied our approach to R0VM by RISC Zero and SP1 by Succinct, two of the most advanced zkVMs in use today. 1/
