AmericanFortress Proposes Quantum-Safe Crypto Wallet Scheme ZK-PoSP

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

ZK-PoSP uses zero-knowledge proofs to keep existing wallet addresses while replacing conventional transaction authorization. AmericanFortress says this approach requires no fund migration, key rotation, or new address format.

The technical paper for ZK-PoSP was released through the International Association for Cryptologic Research's ePrint archive and is designed to operate alongside existing signature systems before replacing the classical signing step if quantum computers become capable of attacking elliptic curve cryptography.
