@QuangVDao Nice! I guess we are sticking with keccak instead of Poseidon :)

[fawad haider @BowlOfChilli]

But probably not true for bit ops like sha256/keccak? Very impressive work nonetheless. 3x is very very fast

[Quang Dao @QuangVDao]

@badcryptobitch @StoffelMPC I see, thanks.

Latest generation of zk is far more performant than your expectations. Jolt for instance proves 1 million RISC-V cycles using only 2-3GB of RAM (soon will go down to <1GB).

In general, zk is converging to ~3 orders of magnitude overhead over native computation

Kinda cool, Lean kernel in solidity, showing up in the kernel arena.

@TheAhmadOsman how do I run this locally?

Introducing GLM-5.2: Frontier Intelligence, Open Weights

- Significant improvements in coding and agentic tasks
- Strong long-horizon capabilities with a 1M context window
- Two levels of reasoning effort: GLM-5.2 (max) pushes the limits, while GLM-5.2 (high) strikes a strong balance between performance and token efficiency
- MIT-licensed open weights
- Same API pricing as GLM-5.1

May be @VitalikButerin can verify this proof against the lean kernel contract(https://t.co/0w2qc2C5kz) in solidity/ethereum . @leanprover Can I make a submission to the Lean Kernel Arena? That would be very cool.

[vitalik.eth @VitalikButerin]

This theorem (left) means, the only way you can make proofs for two different things in the same position in the same Merkle tree, is by breaking the underlying hash function.

As a reviewer, you don't have to verify how Merkle branches are implemented or how the theorem is proven (right), you just have to verify what the theorem says, and that Lean verifies it.

And the beautiful thing is that you can even write live production code (including eg. CLI tools) directly in Lean.

[vitalik.eth @VitalikButerin]

Many people have claimed that with AI-assisted bug finding, secure code (and hence trustless anything) will be impossible.

I have a much more optimistic take, and AI-assisted formal verification is a major part of the reason why:

@leonardoalt @leanprover Who writes the specs? Do you validate/review the specs carefully?

[fawad haider @BowlOfChilli]

And say if the Lean proof is too big/long to verify then we wrap it up in groth16 proof to say it exists :)

@QuangVDao hmmm interesting, haven't heard that direction yet, like hax/aeneas in reverse? that would require another tool which itself needs to be verified, no? or may be you are referring to Boole, upcoming framework in CSlib?

[fawad haider @BowlOfChilli]

@pirapira so do you let LLM write the specification too? The specification is where I imagine all issues popping up in lean "proven" code.

[fawad haider @BowlOfChilli]

@rvtond @MistralAI Claude and homegrown are comparable? That’s very interesting. Can I ask about the homegrown solution?

[fawad haider @BowlOfChilli]

@dhsorens always confused by lean is implemented in lean, would love more of an explanation on this @Leonard41111588. Second there is a C/C++ compiler in the pipeline which generates machine code right and that is not formally verified?

[fawad haider @BowlOfChilli]

A lil ambitious but directionally correct.

[Alex Kontorovich @AlexKontorovich]

Doesn't this mean that all the world's code needs to be rewritten (and verified) in Lean @leanprover, ASAP??

[fawad haider @BowlOfChilli]

@Leonard41111588 Great contribution. What happens to the current millions of lines of code(in mathlib etc ) in 2-3 years? Constant rewrite ?

[fawad haider @BowlOfChilli]

@dhsorens Link doesn't work. Seems like an interesting talk

[fawad haider @BowlOfChilli]

@royvanrijn @Leonard41111588 Oh just seeing this, didn’t know an open source model existed just for lean. This is very very cool. But curious what’s the business model here then?

Just a few years ago, combining AI and formal mathematics was science fiction. Now it's happening. Interview with @ETAPSconf on Lean, AI, and why formal methods have never mattered more. https://t.co/IdG121FWAk
