Function zebra_chain::sapling::commitment::pedersen_hashes::pedersen_hash_to_point

pub fn pedersen_hash_to_point(
    domain: [u8; 8],
    M: &BitVec<u8, Lsb0>
) -> ExtendedPoint

“…an algebraic hash function with collision resistance (for fixed input length) derived from assumed hardness of the Discrete Logarithm Problem on the Jubjub curve.”

PedersenHash is used in the definitions of Pedersen commitments (§ 5.4.7.2 ‘Windowed Pedersen commitments’), and of the Pedersen hash for the Sapling incremental Merkle tree (§ 5.4.1.3 ‘MerkleCRH^Sapling Hash Function’).
