Struct TxCreationKeys

pub struct TxCreationKeys {
    pub per_commitment_point: PublicKey,
    pub revocation_key: RevocationKey,
    pub broadcaster_htlc_key: HtlcKey,
    pub countersignatory_htlc_key: HtlcKey,
    pub broadcaster_delayed_payment_key: DelayedPaymentKey,
}

Expand description

The set of public keys which are used in the creation of one commitment transaction. These are derived from the channel base keys and per-commitment data.

A broadcaster key is provided from potential broadcaster of the computed transaction. A countersignatory key is coming from a protocol participant unable to broadcast the transaction.

These keys are assumed to be good, either because the code derived them from channel basepoints via the new function, or they were obtained via CommitmentTransaction.trust().keys() because we trusted the source of the pre-calculated keys.

Fields§

§per_commitment_point: PublicKey

The broadcaster’s per-commitment public key which was used to derive the other keys.

§revocation_key: RevocationKey

The revocation key which is used to allow the broadcaster of the commitment transaction to provide their counterparty the ability to punish them if they broadcast an old state.

§broadcaster_htlc_key: HtlcKey

Broadcaster’s HTLC Key

§countersignatory_htlc_key: HtlcKey

Countersignatory’s HTLC Key

§broadcaster_delayed_payment_key: DelayedPaymentKey

Broadcaster’s Payment Key (which isn’t allowed to be spent from for some delay)

Implementations§

impl TxCreationKeys

pub fn derive_new<T>( secp_ctx: &Secp256k1<T>, per_commitment_point: &PublicKey, broadcaster_delayed_payment_base: &DelayedPaymentBasepoint, broadcaster_htlc_base: &HtlcBasepoint, countersignatory_revocation_base: &RevocationBasepoint, countersignatory_htlc_base: &HtlcBasepoint, ) -> TxCreationKeys
where T: Signing + Verification,

Create per-state keys from channel base points and the per-commitment point. Key set is asymmetric and can’t be used as part of counter-signatory set of transactions.

pub fn from_channel_static_keys<T>( per_commitment_point: &PublicKey, broadcaster_keys: &ChannelPublicKeys, countersignatory_keys: &ChannelPublicKeys, secp_ctx: &Secp256k1<T>, ) -> TxCreationKeys
where T: Signing + Verification,

Generate per-state keys from channel static keys. Key set is asymmetric and can’t be used as part of counter-signatory set of transactions.
