   This pull request proposes a new BIP for a standard, interoperable format for encrypted wallet backups and transfers.

   The core design choice is the separation of the data payload from the cryptographic container. This BIP specifies the payload format, while mandating that it must be encrypted by a container defined in companion proposals.

   Key features include:

   • CBOR Serialisation: Uses CBOR for a compact, efficient, and extensible binary format suitable for resource-constrained devices.
   • Descriptor-Centric: Aligns with modern wallet architecture by using BIP 380 Output Script Descriptors as the primary method for defining accounts.
   • Comprehensive Data: The schema includes accounts, master secret material, transaction data, UTXOs and standardised metadata.

   This proposal was previously posted to the Bitcoin-Dev mailing list: https://groups.google.com/g/bitcoindev/c/3I-qtBhzIGY

   Seeking assignment of a BIP number and welcoming all feedback.

   Hello @KeysSoze,

   This document is incorrectly formatted in a manner that makes me think that it was AI generated. If you are still interested in pursuing this proposal, could you please fix the formatting?

   At this time, given the lack of replies on the mailing list and comments on this PR, it is not clear to me that this proposal is being pursued for implementation by any Bitcoin project. Given that there are several other backup related proposals in flight, perhaps some of the corresponding authors would be interested in reviewing your document if you review theirs.

   I‘d be happy to provide a more thorough review when this proposal has gotten review from other parties and that review has been addressed, or the proposal otherwise distinguishes itself from its perceived AI-generated origin.
