AmericanFortress claims its post-quantum protocol can freeze and protect Satoshi's 1.1M BTC — without a single fund migration!

AmericanFortress, a privacy-focused blockchain startup backed by an $8 million seed round, has unveiled a patent-pending post-quantum signature scheme it says can secure existing crypto assets — including Satoshi Nakamoto's dormant 1.1 million BTC — against future quantum attacks without requiring mass fund migrations. The firm estimates over $600 billion in crypto assets are currently vulnerable to quantum reversal of exposed public keys, with nearly 5 million BTC in dormant wallets alone representing roughly $400 billion at risk.

The core mechanism relies on a backward-compatible soft fork and zero-knowledge proofs to freeze pre-BIP32 addresses — wallets that predate seed-phrase derivation and cannot be automatically upgraded. CEO Michal Pospieszalski says a minor BIP would trigger a defensive freeze on those funds until the community votes to move, burn, or redistribute them…
