Struct DelayedPaymentBasepoint

pub struct DelayedPaymentBasepoint(pub PublicKey);

Base key used in conjunction with a per_commitment_point to generate a DelayedPaymentKey.

The delayed payment key is used to pay the commitment state broadcaster their non-HTLC-encumbered funds after a delay to give their counterparty a chance to punish if the state broadcasted was previously revoked.

Implementations

impl DelayedPaymentBasepoint

pub fn to_public_key(&self) -> PublicKey

Get inner Public Key

pub fn derive_add_tweak(&self, per_commitment_point: &PublicKey) -> Hash

Derives the “tweak” used in calculate DelayedPaymentKey::from_basepoint.

DelayedPaymentKey::from_basepoint calculates a private key as: privkey = basepoint_secret + SHA256(per_commitment_point || basepoint)

This calculates the hash part in the tweak derivation process, which is used to ensure that each key is unique and cannot be guessed by an external party.

Trait Implementations

impl Clone for DelayedPaymentBasepoint

fn clone(&self) -> DelayedPaymentBasepoint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DelayedPaymentBasepoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<PublicKey> for DelayedPaymentBasepoint

fn from(value: PublicKey) -> DelayedPaymentBasepoint

Converts to this type from the input type.

impl Hash for DelayedPaymentBasepoint

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DelayedPaymentBasepoint

fn eq(&self, other: &DelayedPaymentBasepoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Readable for DelayedPaymentBasepoint

fn read<R>(r: &mut R) -> Result<DelayedPaymentBasepoint, DecodeError>

where R: Read,

Reads a Self in from the given Read.

impl Writeable for DelayedPaymentBasepoint

fn write<W>(&self, w: &mut W) -> Result<(), Error>

where W: Writer,

Writes self out to the given Writer.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
