Satoshi’s 1.1 Million Bitcoin and Millions More Can Be Saved From Quantum Attack, Says Expert

Why It Matters

By safeguarding up to $400 billion of dormant Bitcoin and billions more across other chains, the proposal mitigates a looming quantum‑computing threat without forcing costly mass migrations. Its low‑overhead design could set a new industry standard for quantum‑proofing legacy crypto assets.

Key Takeaways

• AmericanFortress proposes soft‑fork freeze for pre‑BIP32 Bitcoin addresses.
• Solution protects Satoshi’s 1.1 M BTC and ~5 M dormant coins.
• $8M seed round led by SAVA, Moon Pursuit, 0G Labs.
• Zero‑knowledge proofs enable protection without performance loss.
• Quantum‑proof SDK being licensed to Layer 1 and Layer 2 chains.

Pulse Analysis

The quantum‑computing horizon is rapidly shifting from theoretical to practical, and the cryptographic foundations of most blockchains were never designed to withstand attacks from large‑scale quantum processors. Public keys exposed on‑chain can be reverse‑engineered, leaving pre‑BIP32 addresses—those that lack hierarchical deterministic seed phrases—particularly vulnerable. With an estimated $400 billion tied up in Satoshi‑era wallets and another $600 billion across other chains, the industry faces a potential systemic shock if quantum capabilities mature faster than defensive measures.

AmericanFortress’s approach sidesteps the costly migration strategies favored by many post‑quantum projects. By embedding a patent‑pending signature scheme into a soft fork, the protocol can freeze vulnerable addresses at the protocol layer while preserving existing transaction semantics. Zero‑knowledge proofs verify master‑seed ownership at spend time, and three tiers—pre‑BIP32 protection, standard BIP32 hardening, and a high‑speed QBIP32 derivation—ensure compatibility across legacy and modern wallets. Early tests suggest negligible latency, a stark contrast to the 40 % throughput drop observed on BNB Chain during comparable quantum‑security trials.

If adopted, the solution could reshape risk management for institutional investors and custodians who hold large dormant positions. The $8 million seed backing signals strong venture confidence, and the forthcoming Paris presentation may accelerate licensing deals with Layer 1 and Layer 2 protocols. However, the governance model—freezing assets until a community vote determines their fate—introduces new coordination challenges. Successful deployment would not only protect billions of dollars but also establish a blueprint for future quantum‑resilient upgrades across the decentralized finance ecosystem.
