- The page reports 406,854 gas for the worst-case verifier at n = 1024, measured on a mainnet fork.
Field notes
The page says challenge instances are drawn from true roots of x^n + 1 modulo 12289 and seeded with drand after launch, with no planted key. A reveal includes a polynomial pair and two integer quotients; the hook checks five polynomials at one keccak point, with coefficient widths capped to force an exact identity. The site reports its worst-case verifier gas from a mainnet-fork measurement.
