What to know:
- AmericanFortress has unveiled a patent-pending post-quantum signature scheme that aims to protect existing crypto assets, including dormant wallets, from future quantum attacks without mass fund migrations.
- The proposed protocol would utilize a backward-compatible soft fork and zero-knowledge proofs to freeze and secure vulnerable pre-BIP32 bitcoin addresses, such as Satoshi-era wallets, while allowing governance to later decide whether to move, burn or redistribute the funds.
- Backed by an $8 million seed round, AmericanFortress says its approach offers quantum protection for major chains like Bitcoin, Ethereum, Solana and Tron with negligible performance impact and simple node and wallet software updates.
