Quantum-Safe Wallet Security Without Moving Funds

AmericanFortress has proposed a cryptographic approach to make cryptocurrency wallets more resilient to potential future quantum attacks without requiring users to move funds, rotate keys, or change their wallet addresses.

The company's scheme is designed to fit seed-based HD wallet constructions and is compatible with wallets used across networks like Bitcoin, Ethereum, and Solana.

Instead of relying on discarding the existing elliptic-curve-based key material, AmericanFortress introduces an additional verification layer that leverages zero-knowledge proofs built from the wallet's original seed phrase.
