Struct DelayedPaymentKey

pub struct DelayedPaymentKey(pub PublicKey);

Expand description

A derived key built from a DelayedPaymentBasepoint and per_commitment_point.

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

[See the BOLT specs] https://github.com/lightning/bolts/blob/master/03-transactions.md#localpubkey-local_htlcpubkey-remote_htlcpubkey-local_delayedpubkey-and-remote_delayedpubkey-derivation for more information on key derivation details.
