With The Graph or Dune, you trust that the data was indexed correctly.
With Willow, you get a proof that shows:
- Every event is really on-chain
- No events were missed
- Every value computed from the events is correct
And your smart contract can verify the proof itself 🤝

@zsfelfoldi gets it. EIP-8304 (Trustless Log Index) is massively undervalued.
Verifiable data access is a huge weak spot for crypto, and as financial institutions come onchain, it'll become glaring.
@willow_protocol is happy to build a verifier for it.

Truly an amazing achievement from @AnthropicAI.
Formal verification is something @erictgleeson and I have been talking about a lot recently.
ZK proofs let you verify a computation without re-executing it, but the code still needs to be inspected and understood in order to know what was actually proven.
Very few people have the ability to do that, and even fewer will ever take the time.
Code audits help with this. The auditors are professionals and if they say it’s good you can reasonably trust them. But it’s not bulletproof. Audited systems still get hacked.
Formal verification promises a much stronger check on the code itself. It’s basically a proof that the implementation matches its spec, and a good spec is much easier to understand than the circuit. It’s an excellent tool for strengthening a protocol’s trustlessness story.
This is something we’re very interested in and looking into now for @willow_protocol.
Checking that a major mathematical proof is correct can take years. Formalization—converting the mathematical reasoning into a form computer proof assistants like Lean can verify—can help.
Last month, Claude completed the first formalized proof of Fermat’s Last Theorem, one of the most famous theorems of all time. This was a project experts thought would take many years. It is the largest Lean proof ever written.
Fermat’s Last Theorem was first proven in 1995 by Sir Andrew Wiles, more than 350 years after it was conjectured. Our proof, which totals over 13 million lines of code, provides machine verification. More importantly, it proves over 29,000 other theorems that the proof requires, across many areas of math which had never before been formalized.
We see this as a major step in the long process of firming up the core of mathematical knowledge, building on work from three centuries of mathematicians and hundreds of contributors to Lean and Mathlib. We are optimistic that AI-assisted verification of mathematical proofs will help reduce the burden of refereeing mathematics in an era where more proofs are being produced than ever before.

Ethereum is cool because
people around the world have come together across a vast network of independent computers to coordinate around a shared version of reality every 12 seconds (and soon shorter if we can get quick slots to be included in the Hegotá upgrade)
We are on the brink of a tokenized equities boom. Ethereum should be able to contribute to price discovery as well as possible. Faster slots are the way.
Wouldn't slots still be too long? Yes. We need to reduce them iteratively. But, Ethereum can start contributing to price discovery.
PropAMMs and Frequent Batch Auctions are market design innovations that allow even slower domains to contribute to price discovery. Still, speed matters.
Let's not midcurve: faster = better. For DeFi it's obvious. It's also better for user experience. It's also better for robustness. EIP-8198 for Hegotá.
