Infrastructure & Tools

Privacy-focused blockchain startup AmericanFortress completes $8 million seed round.

Privacy-focused blockchain startup AmericanFortress has completed an $8 million seed round led jointly by SAVA Digital Assets Fund, Moon Pursuit Capital, and 0G Labs. The company has also launched a patent-pending post-quantum signature scheme designed to protect existing crypto assets from future quantum attacks without requiring large-scale asset migration.

This proposal safeguards approximately 1.1 million bitcoins owned by Satoshi Nakamoto and nearly 5 million bitcoins in dormant accounts, with a total value of around $400 billion. By using a backward-compatible soft fork and zero-knowledge proofs, it freezes and secures vulnerable pre-BIP32 Bitcoin addresses, with the community later deciding through governance how to handle the frozen assets. The proposal has negligible impact on the performance of major blockchains and requires only updates to node and wallet software. A quantum-safe solution is expected to be ready for discussion in the coming weeks and will be officially launched in Paris on June 2.
