"WebFeb 1, 2024 · Pedersen commitment uses random public generators G and H of a suitable large group where the Discrete Logarithm is hard, thus G and H can safely be assumed distinct. Also, that condition implies no integer w such that G = w H can be found by anyone. These facts are assumed or stated. C = a G + b H is a point on the curve " - Pedersen commitment python

Weba soft commitment is initially created to \no message", and it can later be soft-opened (or teased) to any m, but it cannot be hard-opened. 1.1 Our Contributions In this paper we introduce a new and simple, yet powerful notion of commitment, that we call Vector Commitment (VC, for short). Informally, VCs allow to commit to an ordered sequence ... WebA commitment scheme is ⊗-homomorphic if there exists an eﬃcient coordinate-wise multiplication operation ·deﬁned over Cand Dsuch that Compk(m1)·Compk(m2) ≡Compk(m1 ⊗m2) , where the distributions coincide even if Compk(m1) is ﬁxed.
