Struct HtlcBasepoint

pub struct HtlcBasepoint(pub PublicKey);

Expand description

Base key used in conjunction with a per_commitment_point to generate an HtlcKey.

HTLC keys are used to ensure only the recipient of an HTLC can claim it on-chain with the HTLC preimage and that only the sender of an HTLC can claim it on-chain after it has timed out. Thus, both channel counterparties’ HTLC keys will appears in each HTLC output’s script.

Implementations§

impl HtlcBasepoint

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 HtlcKey::from_basepoint.

HtlcKey::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.
