But we should take the risks to cryptography from AI-accelerated math seriously.&#8221;<\/p><\/blockquote>\n<h2>OpenAI's math advances trigger warnings<\/h2>\n<p>His comments followed Ethereum researcher Justin Drake\u2019s call for <a href=\"https:\/\/cryptoslate.com\/openais-math-breakthrough-raises-fears-ai-could-break-bitcoin-and-ethereum-security-within-months\/\">the industry to begin preparing for \u201cbunker mode,\u201d<\/a> including moving assets toward fresh addresses whose public keys have never been exposed onchain.<\/p>\n<p>Drake raised the possibility that advances in artificial intelligence could accelerate mathematical attacks on the <a href=\"https:\/\/cryptoslate.com\/new-bitcoin-upgrade-catches-hidden-key-leaks-hiding-the-exact-fix\/\">elliptic-curve cryptography used by Bitcoin and Ethereum.<\/a><\/p>\n<p>The debate intensified after OpenAI published new mathematical results generated by an internal frontier model on Oct. 6, including machine-generated proofs formalized in Lean. OpenAI did not report any attack on blockchain cryptography, and neither Buterin nor Drake pointed to evidence that ECDSA has been practically broken.<\/p>\n<p>Buterin\u2019s warning extends beyond that immediate concern. He singled out lattice-based cryptography, including ML-DSA, as an area where AI-driven mathematical discovery could erode assumed security margins over the next two years.<\/p>\n<p>That raises a harder problem for an industry already preparing for quantum computers. Lattice-based systems are among the leading technologies designed to replace cryptography vulnerable to sufficiently powerful quantum machines. NIST <a href=\"https:\/\/csrc.nist.gov\/pubs\/fips\/204\/final\">standardized<\/a> ML-DSA in 2024 as a post-quantum digital-signature algorithm.<\/p>\n<p>Buterin argued that the underlying mathematical structures supporting such systems may contain weaknesses researchers have yet to discover.<\/p>\n<p>He compared the risk to the history of integer factorization. Improvements such as the general number field sieve dramatically reduced the work required to attack RSA compared with naive methods, forcing cryptographic systems to use much larger keys.<\/p>\n<p>AI could compress decades of similar mathematical progress into a much shorter period, he said, potentially uncovering comparable advances against elliptic curves or lattice problems.<\/p>\n<p>\u201cIf AI will bring us 50 years of math in 2 years,\u201d Buterin wrote, those advances could include breakthroughs that substantially improve attacks on lattice cryptography.<\/p>\n<h2>Ethereum leans further into hash-based security<\/h2>\n<p>That concern helps explain Ethereum developers\u2019 growing preference for cryptographic designs based primarily on hash functions.<\/p>\n<p>Buterin said <a href=\"https:\/\/cryptoslate.com\/justin-drake-reveals-10-year-lean-ethereum-roadmap-to-achieve-10k-tps-on-mainnet\/\">Ethereum\u2019s \u201clean\u201d roadmap<\/a> has moved toward hash-only systems over the past year, avoiding lattice-based signatures such as ML-DSA and Falcon and reducing reliance on lattice-based commitments inside zero-knowledge proofs.<\/p>\n<p>Hash-based signature systems, including WOTS and SPHINCS, play a larger role in that direction because they depend less on mathematical structures that could yield unexpected shortcuts to attackers.<\/p>\n<p>Buterin argued that structured mathematical objects create more room for AI-assisted discovery. Elliptic curves, for example, rely on properties including group operations and other exploitable mathematical relationships. Lattice systems similarly depend on families of difficult problems whose practical resistance could change if researchers discover more efficient attacks.<\/p>\n\n<div class=\"cs-article-embed\">\n    <a href=\"https:\/\/cryptoslate.com\/ethereums-2029-quantum-deadline-is-starting-to-reshape-what-gets-built-next\/\" class=\"cs-article-embed__link\">\n        <div class=\"cs-article-embed__body\">\n            <span class=\"cs-article-embed__related-reading\">Related Reading<\/span>\n            <h3 class=\"cs-article-embed__title\">Ethereum\u2019s 2029 quantum deadline is starting to reshape what gets built next<\/h3>\n        <\/div>\n        <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\">\n            <i class=\"fa-light fa-arrow-up-right\"><\/i>\n        <\/span>\n    <\/a>\n<\/div>\n\n<p>Hashes are designed to expose far less structure.<\/p>\n<p>That distinction does not solve every problem. Public-key encryption, used in secure messaging, anonymous communications, websites, and other systems, cannot generally be built from hashes alone. Those applications require mathematical structures that create a trapdoor allowing authorized users to decrypt information.<\/p>\n<p>Buterin suggested that systems relying on those structures may eventually need substantially larger security parameters. He said multiplying key sizes by as much as ten could become reasonable if AI sharply improves cryptanalytic techniques.<\/p>\n<p>The consequences would extend well beyond blockchains. Secure messaging systems, VPNs, Tor, encrypted web traffic and privacy protocols could face similar trade-offs between performance and wider security margins.<\/p>\n<h2>Buterin warns against panic migrations<\/h2>\n<p>For crypto holders, the immediate precautions are narrower.<\/p>\n<p>Buterin said users who can easily keep funds in addresses that have never signed a transaction may gain additional protection because their public keys remain hidden behind address hashes. Once an account sends a transaction, its <a href=\"https:\/\/cryptoslate.com\/who-pays-when-bitcoin-disappears-without-anyone-stealing-the-keys\/\">public key<\/a> becomes visible.<\/p>\n<p>Multisig operators could also reduce exposure by gathering signatures offchain and rotating signer keys after operations, limiting how long an exposed key remains useful if ECDSA security deteriorates.<\/p>\n<p>Buterin nonetheless warned against treating those precautions as an emergency migration order. He said he has personally lost more money through failed migrations than through hacks.<\/p>\n<p>That leaves wallet providers, custodians and protocol developers with a more complicated task than simply rotating keys. They must prepare for faster-moving cryptographic risk while avoiding upgrades that introduce operational failures of their own.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>He favors unused addresses when migration is easy, while warning that AI could weaken cryptography designed to resist quantum attacks.<\/p>\n","protected":false},"author":720,"featured_media":569891,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[78326,77968,29,80837,60206],"tags":[81114,76128,72190,78951],"post_folder":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v21.9 (Yoast SEO v21.9.1) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Vitalik Buterin urges calm as AI raises new fears over Bitcoin and Ethereum cryptography security<\/title>\n<meta name=\"description\" content=\"Vitalik Buterin warned that AI could weaken ECDSA and some post-quantum systems, while stressing there is no reason for emergency action\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/cryptoslate.com\/vitalik-buterin-urges-calm-as-ai-raises-new-fears-over-bitcoin-and-ethereum-cryptography-security\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Vitalik Buterin urges calm as AI raises new fears over Bitcoin and Ethereum cryptography security\" \/>\n<meta property=\"og:description\" content=\"Vitalik Buterin warned that AI could weaken ECDSA and some post-quantum systems, while stressing there is no reason for emergency action\" \/>\n<meta property=\"og:url\" content=\"https:\/\/cryptoslate.com\/vitalik-buterin-urges-calm-as-ai-raises-new-fears-over-bitcoin-and-ethereum-cryptography-security\/\" \/>\n<meta property=\"og:site_name\" content=\"CryptoSlate\" \/>\n<meta property=\"article:published_time\" content=\"2026-10-08T08:40:15+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2026-10-08T08:15:18+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/10\/fresh-address-warning.webp\" \/>\n\t<meta property=\"og:image:width\" content=\"1280\" \/>\n\t<meta property=\"og:image:height\" content=\"720\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/webp\" \/>\n<meta name=\"author\" content=\"Oluwapelumi Adejumo\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:creator\" content=\"@cryptoslate\" \/>\n<meta name=\"twitter:site\" content=\"@cryptoslate\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Oluwapelumi Adejumo\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"4 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"NewsArticle\",\"@id\":\"https:\/\/cryptoslate.com\/vitalik-buterin-urges-calm-as-ai-raises-new-fears-over-bitcoin-and-ethereum-cryptography-security\/#article\",\"isPartOf\":{\"@id\":\"https:\/\/cryptoslate.com\/vitalik-buterin-urges-calm-as-ai-raises-new-fears-over-bitcoin-and-ethereum-cryptography-security\/\"},\"author\":{\"@type\":\"Person\",\"@id\":\"https:\/\/cryptoslate.com\/author\/oluwapelumi-adejumo\/#person\",\"name\":\"Oluwapelumi Adejumo\",\"url\":\"https:\/\/cryptoslate.com\/author\/oluwapelumi-adejumo\/\",\"mainEntityOfPage\":{\"@id\":\"https:\/\/cryptoslate.com\/author\/oluwapelumi-adejumo\/\"},\"image\":{\"@type\":\"ImageObject\",\"@id\":\"https:\/\/cryptoslate.com\/author\/oluwapelumi-adejumo\/#authorimage\",\"url\":\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/10\/profile-oluwapelumi-adejumo-1-300x300.jpg\",\"contentUrl\":\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/10\/profile-oluwapelumi-adejumo-1-300x300.jpg\",\"caption\":\"Oluwapelumi Adejumo\"},\"jobTitle\":\"Senior Reporter\",\"description\":\"Oluwapelumi values Bitcoin's potential.
