Struct FeeSigmaProofContext

#[repr(C)]pub struct FeeSigmaProofContext {
    pub fee_commitment: PedersenCommitment,
    pub delta_commitment: PedersenCommitment,
    pub claimed_commitment: PedersenCommitment,
    pub max_fee: PodU64,
}

Expand description

The context data needed to verify a pubkey validity proof.

We refer to ZK Token proof for the formal details on how the fee sigma proof is computed.

Fields§

§fee_commitment: PedersenCommitment

The Pedersen commitment to the transfer fee

§delta_commitment: PedersenCommitment

The Pedersen commitment to the real delta fee.

§claimed_commitment: PedersenCommitment

The Pedersen commitment to the claimed delta fee.

§max_fee: PodU64

The maximum cap for a transfer fee
