Struct dbc::anchor::Anchor

pub struct Anchor<L: Proof + StrictDumb, D: Proof<M>, M: DbcMethod = Method> {
    pub mpc_proof: L,
    pub dbc_proof: D,
    pub method: M,
}

Anchor is a data structure used in deterministic bitcoin commitments for keeping information about the proof of the commitment in connection to the transaction which contains the commitment, and multi-protocol merkle tree as defined by LNPBP-4.

Fields

mpc_proof: L

Structured multi-protocol LNPBP-4 data the transaction commits to.

dbc_proof: D

Proof of the DBC commitment.

method: M

Method used by the anchor

Implementations

impl<L: Proof + StrictDumb, D: Proof<M>, M: DbcMethod> Anchor<L, D, M>

pub fn new(mpc_proof: L, dbc_proof: D) -> Self

Constructs anchor for a given witness transaction id, MPC and DBC proofs.

pub fn matches(&self, other: &Self) -> bool

Verifies whether one anchor matches another ancor.

This is not the same as Eq, since two anchors may reveal different messages in their MPC proofs, and this be non-equivalent, at the same time matching each other , i.e. having the same merkle root and producing the same commitments.

impl<D: Proof<M>, M: DbcMethod> Anchor<MerkleProof, D, M>

pub fn into_merkle_block( self, protocol_id: impl Into<ProtocolId>, message: impl Into<Message>, ) -> Result<Anchor<MerkleBlock, D, M>, InvalidProof>

Reconstructs anchor containing merkle block

pub fn to_merkle_block( &self, protocol_id: impl Into<ProtocolId>, message: impl Into<Message>, ) -> Result<Anchor<MerkleBlock, D, M>, InvalidProof>

Reconstructs anchor containing merkle block

pub fn verify( &self, protocol_id: impl Into<ProtocolId>, message: impl Into<Message>, tx: &Tx, ) -> Result<Commitment, VerifyError<D::Error>>

Verifies that the transaction commits to the anchor and the anchor commits to the given message under the given protocol.

pub fn convolve( &self, protocol_id: impl Into<ProtocolId>, message: impl Into<Message>, ) -> Result<Commitment, InvalidProof>

Verifies that the anchor commits to the given message under the given protocol.

impl<D: Proof<M>, M: DbcMethod> Anchor<MerkleBlock, D, M>

pub fn to_merkle_proof( &self, protocol: impl Into<ProtocolId>, ) -> Result<Anchor<MerkleProof, D, M>, LeafNotKnown>

Conceals all LNPBP-4 data except specific protocol and produces merkle proof anchor.

pub fn into_merkle_proof( self, protocol: impl Into<ProtocolId>, ) -> Result<Anchor<MerkleProof, D, M>, LeafNotKnown>

Conceals all LNPBP-4 data except specific protocol and converts anchor into merkle proof anchor.

pub fn conceal_except( &mut self, protocols: impl AsRef<[ProtocolId]>, ) -> Result<usize, LeafNotKnown>

Conceals all LNPBP-4 data except specific protocol.

pub fn merge_reveal(self, other: Self) -> Result<Self, MergeError>

Merges two anchors keeping revealed data.
