AmericanFortress has proposed a post-quantum security scheme designed to protect existing Bitcoin, Ethereum, and Solana wallet addresses without requiring holders to move funds or rotate their keys.
Summary
- ZK-PoSP keeps existing wallet addresses while replacing conventional transaction authorization with zero-knowledge proofs.
- AmericanFortress says the scheme requires no fund migration, key rotation, or new address format.
- The approach remains a proposal and would require node-level upgrades before any blockchain could enforce it.
- Its post-quantum security remains conjectural, according to the technical paper, rather than proven against a working attack.
