AmericanFortress Unveils Quantum-Resistant Wallet Protection Without Fund Migration

Blockchain security company AmericanFortress has unveiled a cryptographic scheme that could protect existing cryptocurrency wallets from future quantum attacks without requiring users to move funds, rotate keys or change wallet addresses.

The proposal, published in a technical paper on the Cryptography ePrint Archive, is compatible with seed-based hierarchical deterministic wallets used across Bitcoin (BTC), Ethereum (ETH), Solana (SOL) and other blockchain networks that rely on elliptic curve cryptography.

According to AmericanFortress, the scheme uses zero-knowledge proofs derived from a wallet's original seed phrase instead of replacing the elliptic curve cryptography underlying existing wallets. Participating nodes would verify those proofs while users continue signing transactions with their existing keys.

AmericanFortress cited a recent Bloomberg analysis estimating that up to $470 billion in Bitcoin could be vulnerable to quantum attacks if sufficiently powerful quantum computers become available.
