PQ-single-address-backup - BIP-38 for P2MR (bc1z) - 104-char encrypted backup format

Considering the longevity and reliability of paper backups, it is essential to maintain a fixed length for these documents. This strategy not only ensures consistency across stored data but also aids in better management and retrieval processes over extended periods. However, despite the benefits of a fixed length, solely relying on this measure may not sufficiently instill confidence in the validity of the backed-up data.

Incorporating a typo check from the initial version emerges as a crucial step to enhance the integrity of paper backups. Even with a consistent length, errors such as copied or mistyped characters can occur, leaving the backup unchanged in size but potentially compromised in accuracy. Therefore, implementing a mechanism to detect and correct such errors before attempting data recovery is indispensable. This approach significantly bolsters user trust and reduces the likelihood of errors during the restoration of critical information.
