Vector commitments gain a lot of attention because of their wide usage in applications such as blockchain and accumulator. Mercurial vector commitments and mercurial functional commitments (MFC), as significant variants of VC, are the central techniques to construct more advanced cryptographic primitives such as zero-knowledge set and zero-knowledge functional elementary database (ZK-FEDB).
However, the current MFC only …
