Trying to think through use cases of preventing payment fraud from compromised nsecs that can control wallet spend.
I believe that if an nsec is known, you can derive a public key and potentially match that to lightning node ID of the payment. I think you can derive lightning private keys as well from an nsec but correct me if I’m wrong.
If so, commerce companies could have an up to the minute list of known compromised nsecs to deny payments from or to hold shipments for compromised payments.
