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: PublicKey
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: PublicKey
Broadcaster’s HTLC Key
countersignatory_htlc_key: PublicKey
Countersignatory’s HTLC Key
broadcaster_delayed_payment_key: PublicKey
Broadcaster’s Payment Key (which isn’t allowed to be spent from for some delay)

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.
