preparing a crypto wallet for future threats means looking beyond the keys it generates today. @Americanfort_io is exploring this through QBIP-32, a proposed approach to wallet key derivation that aims to support different cryptographic schemes, including quantum-resistant options. but there's a distinction worth keeping in mind. protecting key derivation doesn't automatically protect every part of a wallet. transaction signatures also need to withstand the relevant threats, and the underlying blockchain must be able to support the cryptography being used. AmericanFortress is also researching ZKPoSP, which explores how to prove that a public wallet key was derived from a particular seed without revealing the seed itself. the research is available on IACR ePrint as 2026/1508. it's a preprint, not a peer-reviewed paper or proof that a complete quantum-resistant wallet system has been deployed. i find this approach worth examining because future wallet security is a system-wide problem. stronger key derivation, secure signatures and practical blockchain support all have to fit together. the real measure of progress isn't simply claiming to be quantum-resistant. it's showing which parts are protected, how the mechanisms work and what still needs to be tested. that's the kind of evidence i'd want to see as this research develops.
