65 * ChannelMonitorUpdate on disk without updating the monitor itself, replaying the journal at

79 * least a final ChannelMonitorUpdate::ChannelForceClosed which must be delivered to at
80 * least one ChannelMonitor copy. Revocation secret MUST NOT be released and offchain channel

87 * update to ensure you can claim from it in case of a duplicate copy of this ChannelMonitor
88 * broadcasts it (e.g distributed channel-monitor deployment)
90 * In case of distributed watchtowers deployment, the new version must be written to disk, as
91 * state may have been stored but rejected due to a block forcing a commitment broadcast. This

1593 * When on-chain outputs are created by rust-lightning (which our counterparty is not able to
1594 * claim at any point in the future) an event is generated which you must track and be able to
1595 * spend on-chain. The information needed to do this is provided in this enum, including the
1596 * outpoint describing which txid and output index is available, the full output which exists at
1597 * that txid/index, and any keys or other information required to sign.

1601 * An output to a script which was provided via KeysInterface, thus you should already know
1602 * how to spend it. No keys are provided as rust-lightning was never given any keys - only the
1603 * script_pubkey as it appears in the output.
1604 * These may include outputs from a transaction punishing our counterparty or claiming an HTLC
1605 * on-chain using the payment preimage or after it has timed out.
1607 LDKSpendableOutputDescriptor_StaticOutput,
1609 * An output to a P2WSH script which can be spent with a single signature after a CSV delay.
1611 * The witness in the spending input should be:
1612 * <BIP 143 signature> <empty vector> (MINIMALIF standard rule) <provided witnessScript>
1614 * Note that the nSequence field in the spending input must be set to to_self_delay
1615 * (which means the transaction is not broadcastable until at least to_self_delay
1616 * blocks after the outpoint confirms).
1618 * These are generally the result of a \"revocable\" output to us, spendable only by us unless
1619 * it is an output from an old state which we broadcast (which should never happen).
1621 * To derive the delayed_payment key which is used to sign for this input, you must pass the
1622 * holder delayed_payment_base_key (ie the private key which corresponds to the pubkey in
1623 * ChannelKeys::pubkeys().delayed_payment_basepoint) and the provided per_commitment_point to
1624 * chan_utils::derive_private_key. The public key can be generated without the secret key
1625 * using chan_utils::derive_public_key and only the delayed_payment_basepoint which appears in
1626 * ChannelKeys::pubkeys().
1628 * To derive the revocation_pubkey provided here (which is used in the witness
1629 * script generation), you must pass the counterparty revocation_basepoint (which appears in the
1630 * call to ChannelKeys::ready_channel) and the provided per_commitment point
1631 * to chan_utils::derive_public_revocation_key.
1633 * The witness script which is hashed and included in the output script_pubkey may be
1634 * regenerated by passing the revocation_pubkey (derived as above), our delayed_payment pubkey
1635 * (derived as above), and the to_self_delay contained here to
1636 * chan_utils::get_revokeable_redeemscript.
1638 LDKSpendableOutputDescriptor_DynamicOutputP2WSH,
1640 * An output to a P2WPKH, spendable exclusively by our payment key (ie the private key which
1641 * corresponds to the public key in ChannelKeys::pubkeys().payment_point).
1642 * The witness in the spending input, is, thus, simply:
1643 * <BIP 143 signature> <payment key>
1645 * These are generally the result of our counterparty having broadcast the current state,
1646 * allowing us to claim the non-HTLC-encumbered outputs immediately.
