Struct secp256k1_zkp::SurjectionProof

pub struct SurjectionProof { /* private fields */ }

Represents a surjection proof.

Implementations

impl SurjectionProof

pub fn new<C: Signing, R: Rng>(
    secp: &Secp256k1<C>,
    rng: &mut R,
    codomain_tag: Tag,
    codomain_blinding_factor: Tweak,
    domain: &[(Generator, Tag, Tweak)]
) -> Result<SurjectionProof, Error>

Prove that a given tag - when blinded - is contained within another set of blinded tags.

Mathematically, we are proving that there exists a surjective mapping between the domain and codomain of tags. Blinding a tag produces a Generator. As such, to create this proof we need to provide the [Generator]s and the respective blinding factors that were used to create them.

impl SurjectionProof

pub fn from_slice(bytes: &[u8]) -> Result<Self, Error>

Creates a surjection proof from a slice of bytes.

pub fn serialize(&self) -> Vec<u8>

Serializes a surjection proof.

The format of this serialization is stable and platform-independent.

pub fn len(&self) -> usize

Find the length of surjection proof when serialized

pub fn verify<C: Verification>(
    &self,
    secp: &Secp256k1<C>,
    codomain: Generator,
    domain: &[Generator]
) -> bool

Verify a surjection proof.
