Privately sending payments while offline with BOLT12

The proposal outlined in the GitHub pull request aims to establish a standard that enables remote controls to communicate securely with a high-uptime home node through BOLT8. This initiative is particularly significant as it seeks to enhance security by facilitating the pairing of remote nodes with hardware wallets, including popular options like Ledger and Coldcard. The emphasis on standardizing control messages within this bLIP (Bitcoin Lightning Improvement Proposal) is driven by the potential to significantly improve the ease of use and security for users interacting with their nodes remotely.

By introducing a standardized protocol for control messages, developers and users alike can benefit from a more streamlined and secure framework for managing their nodes. This standardization effort not only promises to bolster security but also aims at improving the overall user experience by providing a clear set of guidelines for remote communication between devices and nodes in the Bitcoin Lightning Network ecosystem.
