Struct snarkvm_wasm::algorithms::Pedersen

pub struct Pedersen<E, const NUM_BITS: u8>where
    E: Environment,{ /* private fields */ }

Expand description

Pedersen is a collision-resistant hash function that takes a variable-length input. The Pedersen hash function does not behave like a random oracle, see Poseidon for one.
