Pappas et al. proposed HydraProofs in their paper, the first vector commitment scheme that can generate all opening proofs for a vector of size N in O(N) time, and is directly compatible with zkSNARKs families, significantly improving prover time. Pappas等人在论文中提出了HydraProofs,首个能在O(N)时间内为大小为N的向量生成所有 opening 证明的向量承诺方案,并直接兼容于zkSNARKs家族,显著优化了证明者时间。 Pappasらは論文でHydraProofsを提案しました。これは、サイズNのベクトルに対するすべての開示証明書をO(N)時間で生成できる初のベクトルコミットメントスキームであり、zkSNARKsファミリーと直接互換性があるため、プロバー時間を大幅に改善します。
