It is clear to me that the best thing that can happen for the sake of Bitcoin's encryption security is the impossibility of solving this challenge. Assuming that the challenges already solved were completed by the creator themselves, all of this only serves to attest to the level of cryptographic security present in this digital masterpiece created by Satoshi.
Well, in my opinion is actually the other way around if those challenges are solved it should be a clear sign to the bitcoin developers to migrate to another encryption scheme.
It may be one of two things:
- A bigger Elliptic Curve.
- A post-Quantum Algorithm.
Also you need to consider that this challenge has two variants, one for public key and one for address.
Public keys as we see are secure if they is great than 130 bits (By the moment), Also you need to consider that real wallets are usually near 256 bits
Address security by the moment are secure if the address is higher 66 bits.... yes i know if the public keys is leaked it may be completely insecure, but that is only if you know the expected range of such address
Which usually doesn't happen.
