Public key recovery for EC leaves in P2MR (BIP-360)

The focus of future cryptocurrency security enhancements should prioritize providing migration options for the least responsive users, rather than targeting large wallet holders who are likely to adapt quickly. This approach is critical as it aims to minimize the number of users who have not transitioned away from elliptic curve (EC) cryptography by the time more advanced phases of security upgrades, such as post-quantum (PQ) solutions, are implemented. Large wallet holders typically have significant assets at stake and are expected to respond swiftly to changes in security protocols, which supports the argument that they should not be the primary focus during initial stages of migration planning.

Instead, the strategy should involve developing features that allow for an easy transition for all users, especially those less likely to update their security settings proactively. By integrating scripting hooks and other adaptable features into cryptocurrency addresses now, the community can prepare for potential vulnerabilities that might arise if elliptical curve cryptography is compromised. This proactive measure would ensure a broader, more effective update to post-quantum cryptographic solutions when they become necessary. Such planning is essential to maintaining the integrity and security of digital assets in an evolving technological landscape.
