AmericanFortress Unveils Quantum-Safe Crypto Wallet Scheme

AmericanFortress has proposed a post-quantum security scheme designed to protect existing Bitcoin, Ethereum, and Solana wallet addresses. The proposal, called Zero-Knowledge Proof of Seed Provenance (ZK-PoSP), replaces conventional transaction authorization with zero-knowledge proofs without requiring holders to move funds or rotate their keys.

ZK-PoSP keeps existing wallet addresses while proving that a wallet knows the seed used to derive an address without revealing the seed itself. It would operate alongside existing signature systems and replace classical signing if quantum computers become capable of attacking elliptic curve cryptography.

The proposal is designed to cover both the secp256k1 curve (used by Bitcoin) and Ed25519 (commonly used by Solana), as well as hierarchical deterministic wallet standards, including BIP32 and SLIP-10. AmericanFortress reports that generating a one-time proof costs about $0.002 on a 16-core server, while each transaction proof costs roughly $0.00125.

The implementation is reportedly practical for institutional settlement, with hardware acceleration and proving-system improvements expected to bring signing times down further.
