Succinct Arguments over Towers of Binary Fields

ePrint Report: Succinct Arguments over Towers of Binary Fields

Benjamin E. Diamond, Jim Posen

We introduce an efficient SNARK for towers of binary fields. Adapting Brakedown (CRYPTO '23), we construct a multilinear polynomial commitment scheme suitable for polynomials over tiny fields, including that with 2 elements. Our commitment scheme, unlike those of previous works, treats small-field polynomials with zero embedding overhead. We further introduce binary-field adaptations of HyperPlonk's (EUROCRYPT '23) product and permutation checks, as well as of Lasso's lookup. …
