KEVM is an executable semantics. It does not "formally verify" the" entire" EVM in any way. What it actually does is reconcile the yellow paper with the official test suite and serves as a basis for formal verification of EVM bytecode through the Kontrol tool. Wonder which team members who built KEVM would agree with this statement. As one such (former) member, I certainly don't.

The team behind Pi² Labs didn't just build on Ethereum. They formally verified the entire EVM. KEVM. 40,683 tests passed. Ambiguities in the Yellow Paper exposed along the way. You earn the right to build what comes next. ↓

Our Formal Verification team is beginning work on the @brevis_zk Pico RISC-V zkVM, building on our work on SP1 and OpenVM. We are grateful to the @EthereumFndn for supporting this effort.

Presenting "Formalising FRI: A Lean Blueprint of Security" at ETH Denver, Friday Feb 20, 12:40 PM (Futurllama Stage). The FRI protocol is a core component underpinning numerous STARK-based systems. No implementation has a formal proof of correctness. We have made an important first step in this direction by fully formalizing FRI in @leanprover, allowing implementations to be verified against this formalization in future. This is what we do at @NethermindSec. We formalize and formally verify security properties of production-ready zkVMs (SP1 and OpenVM), zk verifiers (zkSync), and protocols (IntMax). If you're designing protocols or building ZK infrastructure where you need the strongest correctness mathematical guarantees available on the market, come find me on Friday or anytime during the week!

It was a great pleasure to lead the formal verification of OpenVM. This is the most complete FV effort to date of a real-world RISC-V zkVM. Big thank you to @theyisun and @jonathanpwang from @axiom_xyz for their support in this process, and to @ethereumfndn for the funding.

Our Formal Verification team led by @PetarMax, with support from @EthereumFndn, has verified in Lean the correctness of the OpenVM RISC-V extension built by @axiom_xyz. This work proves instruction-level correctness and, for the first time, execution and memory consistency. 🧵

ZK circuits are defined by mathematical constraints over finite fields. Their correctness is not a matter of coverage. It is a matter of whether the equations enforce the intended semantics. 1/

The Nethermind Formal Verification team has completed its work on formalizing the FRI protocol in Lean and blueprinting its proof of soundness. Supported by a grant from @ethereumfndn. This result is historically unique. 🧵

@ilyasergey Yes, and what was the complexity of the proof? Did it have any creative insight or was it just brute force and case analysis? Does the paper cover this in more detail?

@PetarMax We gave it a math fact with an admitted proof we felt it would take us a few hours to produce. It returned a proof in a few minutes.

The proof of the last remaining Lean theorem in our upcoming conference submission has now been completed with the help of AI. The research community’s perception of program verification is about to change irreversibly.

It was a privilege to lead this ground-breaking verification work from the @NethermindSec side. We now have in our hands the first formally verified** RISC-V zkVM, and that is @SuccinctLabs's SP1 HyperCube, 64-bit edition no less. ** Terms and conditions apply, see blog.succinct.xyz/nethermind-lea…. 1/

We are delighted to announce that the @NethermindSec Formal Verification team, led by @PetarMax, in tandem with @SuccinctLabs, and with generous support from @ethereumfndn, has formally verified the correctness of all of the core RV-64 chips from the SP1 HyperCube RISC-V zkVM in @leanprover. 1/

@PetarMax @RosuGrigore @chenxiaohong @pisquared I wouldn’t worry too much about fake accounts unless they’re impersonating real people, spreading misinformation, or trying to scam others. Beyond that, as you said, it’s largely out of control.

@PetarMax @RosuGrigore @chenxiaohong We’ve noticed that too. If you see fake accounts using our name or pretending to be from us or @pisquared, please flag them to us and report them to X so X can take them down. Thanks for highlighting this.
