A proposed cryptographic scheme from AmericanFortress would protect existing Bitcoin, Ethereum, and Solana wallets against future quantum attacks. No fund migration is required and wallet addresses would remain unchanged under the proposal.
What AmericanFortress is proposing
The scheme targets wallets already holding assets across all three chains. AmericanFortress frames the protection as a readiness measure against attacks described as future rather than present-day. The source provides no detail on the underlying cryptographic primitives or the mechanism that would secure addresses in place.
What the proposal omits
No implementation timeline is given. The cryptographic primitives are unspecified and no third-party audit is cited. For a scheme claiming to protect wallets against quantum-level risk without touching balances or addresses, those are material gaps. At this stage, "proposed" is the operative word.
The migration-free design is the stated differentiator. Every current holder across Bitcoin, Ethereum, and Solana falls within the addressable scope as described. AmericanFortress has not detailed what deployment would require in practice.
