AmericanFortress Unveils Post-Quantum Security Scheme to Protect Crypto Wallets

AmericanFortress has proposed a new post-quantum security scheme designed to protect existing Bitcoin, Ethereum, and Solana wallet addresses without requiring holders to move funds or rotate their keys.

The scheme, called Zero-Knowledge Proof of Seed Provenance (ZK-PoSP), uses wallet seeds to authorize transactions while keeping the seed itself secret. AmericanFortress claims that ZK-PoSP is the first post-quantum approach that can preserve existing wallet addresses without forcing users to transfer assets.

The proposal relies on hash functions and the soundness of its zero-knowledge proof system, but acknowledges that post-quantum security is 'conjectured' because the underlying assumptions have not been tested against a cryptographically relevant quantum computer. AmericanFortress estimates that generating a one-time proof to secure an address costs about $0.002 on a 16-core server, while each transaction proof costs roughly $0.00125.
