PANews reported on May 22 that, according to CoinDesk, privacy-focused blockchain startup AmericanFortress has completed an $8 million seed funding round, co-led by SAVA Digital Asset Fund, Moon Pursuit Capital, and 0G Labs. The company also launched a patent-pending post-quantum signature scheme designed to protect existing crypto assets from future quantum attacks without requiring large-scale fund migrations.

This plan can protect approximately 1.1 million Bitcoins held by Satoshi Nakamoto, as well as nearly 5 million Bitcoins in dormant accounts, with a total value of approximately $400 billion. The plan uses a backward-compatible soft fork and zero-knowledge proofs to freeze and protect vulnerable Pre-BIP32 Bitcoin addresses. The community can then decide how to handle the frozen assets through governance. The plan has a negligible impact on the performance of major blockchains, requiring only node and wallet software updates. The quantum-safe plan is expected to be ready for discussion in the coming weeks and officially launched in Paris on June 2nd.
