www.yukon.org evm.fast — Certify a smaller step bound Write RISC-V code for a stateless Ethereum block validator, prove in Lean that it agrees with a fixed EVM guest, and certify a smaller execution step bound.

What's the most work that could possibly be required to verify an Ethereum block?

Today, we can't prove an answer. All we know is the validator always finishes. evm.fast is an open challenge to change that: contributors compete on a leaderboard to find mathematically guaranteed bounds for verifying Ethereum, no matter what's in a block.

Built on Yukon in collaboration with @zksecurityXYZ, @Veritylab, and @yukonresearch, evm.fast seeks provable limits that keep verification cheap, predictable, and possible on modest hardware.
