While the concept offers an innovative approach to safeguarding digital assets, it remains an early-stage proposal that would require broad industry adoption before becoming a reality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">ZK-PoSP protects wallets without changing addresses<\/h2>\n\n\n\n<p>Traditional quantum-resistant upgrades often require users to transfer funds into newly generated wallet addresses using different cryptographic standards.<\/p>\n\n\n\n<p>AmericanFortress aims to eliminate that process.<\/p>\n\n\n\n<p>Instead, its proposed <strong>ZK-PoSP<\/strong> system allows wallet owners to prove they possess the original seed phrase used to generate a wallet without revealing the seed itself.<\/p>\n\n\n\n<p>The verification is performed using <strong>zero-knowledge proofs<\/strong>, enabling transactions to be authorized securely while preserving existing wallet addresses.<\/p>\n\n\n\n<p>According to the company, this means users would not need to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Move their crypto holdings<\/li>\n\n\n\n<li>Rotate private keys<\/li>\n\n\n\n<li>Generate new wallet addresses<\/li>\n<\/ul>\n\n\n\n<p>The proposal is intended to work alongside current digital signature systems before eventually replacing traditional signatures if quantum computers become capable of breaking existing cryptography.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Designed for Bitcoin, Ethereum, and Solana<\/h2>\n\n\n\n<p>The proposal targets several of the industry&#8217;s largest blockchain ecosystems.<\/p>\n\n\n\n<p>It supports cryptographic standards currently used by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bitcoin<\/strong>, which relies on the <strong>secp256k1<\/strong> elliptic curve.<\/li>\n\n\n\n<li><strong>Ethereum<\/strong>, which also uses <strong>secp256k1<\/strong>.<\/li>\n\n\n\n<li><strong>Solana<\/strong>, which primarily utilizes <strong>Ed25519<\/strong> signatures.<\/li>\n<\/ul>\n\n\n\n<p>The system is also compatible with widely adopted hierarchical deterministic wallet standards, including <strong>BIP32<\/strong> and <strong>SLIP-10<\/strong>, allowing existing wallet infrastructure to remain largely unchanged.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quantum threat remains a future concern<\/h2>\n\n\n\n<p>Although quantum computing continues to advance, today&#8217;s machines are not yet capable of breaking modern blockchain encryption.<\/p>\n\n\n\n<p>Powerful future quantum computers could theoretically use <strong>Shor&#8217;s algorithm<\/strong> to derive private keys from exposed public keys, potentially compromising wallets protected by current elliptic curve cryptography.<\/p>\n\n\n\n<p>However, recent estimates from Google&#8217;s Quantum AI researchers suggest that attacking <strong>256-bit elliptic curve cryptography<\/strong> would require approximately <strong>1,500 logical qubits<\/strong> and tens of millions of quantum operations\u2014technology that does not currently exist.<\/p>\n\n\n\n<p>As a result, Bitcoin, Ethereum, and other major cryptocurrencies are <strong>not facing an immediate quantum security threat<\/strong>, although researchers continue preparing for long-term risks.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Network upgrades would still be required<\/h2>\n\n\n\n<p>Despite preserving existing wallet addresses, ZK-PoSP cannot simply be added to current blockchain networks.<\/p>\n\n\n\n<p>The proposal would require:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Node software upgrades<\/li>\n\n\n\n<li>Wallet software capable of generating zero-knowledge proofs<\/li>\n\n\n\n<li>Network-wide adoption by developers, miners, validators, and node operators<\/li>\n<\/ul>\n\n\n\n<p>Until blockchain networks formally adopt and enforce these verification rules, wallets with publicly exposed keys would remain vulnerable to future quantum attacks if such technology eventually becomes practical.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Verification costs remain relatively low<\/h2>\n\n\n\n<p>AmericanFortress believes the system can operate efficiently.<\/p>\n\n\n\n<p>According to the company&#8217;s internal testing:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Creating a one-time wallet proof costs approximately <strong>$0.002<\/strong> on a 16-core server.<\/li>\n\n\n\n<li>Each transaction proof costs roughly <strong>$0.00125<\/strong>.<\/li>\n\n\n\n<li>Signing currently takes around <strong>12 seconds<\/strong>.<\/li>\n\n\n\n<li>Verification completes in approximately <strong>9\u201310 milliseconds<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>These figures come from laboratory testing rather than live blockchain deployments, meaning real-world implementation could involve additional infrastructure and operational costs.<\/p>\n\n\n\n<p>The company also noted that future software improvements and hardware acceleration could significantly reduce transaction signing times.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Industry increases focus on post-quantum security<\/h2>\n\n\n\n<p>AmericanFortress&#8217;s proposal arrives amid growing industry attention on quantum-resistant blockchain technology.<\/p>\n\n\n\n<p>Recently, <strong>Strategy<\/strong>, <strong>BlackRock<\/strong>, <strong>Coinbase<\/strong>, and several other companies launched the <strong>Bitcoin Security Consortium<\/strong>, committing <strong>$15 million<\/strong> over the next three years to support post-quantum research.<\/p>\n\n\n\n<p>Meanwhile, the <strong>Ethereum Foundation<\/strong> has established its own dedicated quantum security initiative, exploring alternative signature schemes, zero-knowledge technologies, and migration tools for future protocol upgrades.<\/p>\n\n\n\n<p>These parallel efforts demonstrate that major blockchain organizations are increasingly preparing for a future in which quantum computing may become a practical security concern.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Outlook<\/h2>\n\n\n\n<p>AmericanFortress&#8217;s <strong>ZK-PoSP<\/strong> proposal introduces an interesting approach to post-quantum wallet security by allowing cryptocurrency holders to keep their existing wallet addresses while replacing traditional signature verification with zero-knowledge proofs.<\/p>\n\n\n\n<p>However, the proposal remains theoretical and will require extensive peer review, security audits, and widespread support from blockchain communities before it could be implemented on major networks.<\/p>\n\n\n\n<p>As quantum computing research continues advancing, solutions like ZK-PoSP are likely to become an increasingly important part of discussions surrounding the long-term security of Bitcoin, Ethereum, Solana, and other blockchain ecosystems.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>As concerns over the future impact of quantum computing continue to grow, cybersecurity firm AmericanFortress has
