Covert channel recovery with Oblivious Signatures



Summary:

The email thread discusses the use of cooperative settlement transactions and commitment transactions in the Lightning Network. The sender clarifies that the goal is to offer a cooperative settlement transaction upfront to the possibly recovering party, rather than a commitment transaction. They explain the potential risks involved with sending commitment transactions, as it exposes the recovering party to the punishment mechanism. The sender argues that using oblivious settlement signatures is preferable because it provides a coherent user experience for recovery. However, they also mention working on another recovery idea that involves peer-provided encrypted backup and full channel restoration. The email also touches on the issue of deciding which peer goes first in the negotiation process. Finally, the sender expresses interest in knowing more about option_static_remotekey and its potential security issues.
