When a wallet spends money, it demonstrates in zero knowledge that it has the original master seed and that the seed represents the address&#8217;s cryptographic origin. A child private key may be reversed from a public address by a quantum computer using Shor&#8217;s method. A master seed from an HD generated on chain address cannot be reversed. The security of the technique is based on this imbalance, which has been explicitly shown against quantum polynomial-time attackers.<\/p>\n<p>Crucially, using the same derivation method, the public keys generated are exactly the same as those of a typical BIP32-Ed25519 wallet. No new chain, key re-registration, or address migration.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-split-proof-architecture\">Split-proof Architecture<\/h2>\n<p>The paper&nbsp;presents a split-proof design that divides the workload into two independent parts: a signing proof that is computed once per spend message and has a cost independent of derivation depth, and a derivation proof that is computed once per master key recovery from seed at wallet initialization and reused across all transactions.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-regarding-present-performance\">Regarding Present Performance<\/h2>\n<p>On commodity hardware, full proof creation at a common wallet depth presently takes a few minutes. Split-proof pre-computation and ZK-friendly hash functions are identified as the solution to this recognized shortcoming inherent in HMAC-SHA512 within the STARK circuit. With current hardware, the signature proof vs. HMAC-SHA512 HD derivation takes less than ten seconds. Regardless of wallet depth, verification always takes 18\u201319 milliseconds. The signature size is set as 218.4 KB. In a short while, the team will introduce innovative performance-enhancing techniques that, even with current technology, don&#8217;t alter the user experience.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-regarding-bitcoin\">Regarding Bitcoin<\/h2>\n<p>The present approach is exclusive to Edwards curve chains, including Solana, and BIP32-Ed25519. On the other hand, a secp256k1-native construction is currently in development and will be covered in a later publication. Wallets that calculate key pairs directly rather than via a derivation process are the only funds that cannot be protected against quantum theft like Satoshi&#8217;s early wallets using this new approach.<\/p>\n<p>AmericanFortress is the first privacy infrastructure provider to pursue end-to-end post-quantum security across naming, transaction confidentiality, and key management for all chains thanks to the technology&#8217;s native integration with the company&#8217;s Send-to-Name stealth address system and Confidentiality Machine compliant privacy pools. The solution is being implemented directly in AmericanFortress&#8217;s own wallets and custody systems and made accessible via SDK.<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-acknowledgement\">Acknowledgement<\/h3>\n<p>AmericanFortress would like to express its gratitude to the following team members for this innovation and its implementation: Chief Architect Justus Ranvier, Senior Cryoptographer Vincenzo Botta, Chief Cryptographer Emmanuel Ragnoli, Patents\/Legal Richard Topolewski, and CEO\/CTO Michal Pospieszalski. Additionally, I would want to express my gratitude for the cited research from previous studies that this much depended upon.<\/p>\n<\/p>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The structure uses a ZK-STARK proof in place of the traditional Ed25519 signature phase.
