Falcon is a post-quantum signature tool designed to give Solana a path toward stronger protection if current cryptography becomes unsafe.<\/p>\n<p>The Solana teams said the tool can be activated if needed and should not create a major performance burden. Jump Crypto said Falcon-512 has a smaller signature size than other selected post-quantum standards, which may help protect speed and storage efficiency.<\/p>\n<h2 class=\"wp-block-heading\"><strong>NEAR warns about ownership disputes<\/strong><\/h2>\n<p>Near One has raised a different concern. Its research team said quantum attacks may not only expose private keys, but also create disputes over who owns crypto after stolen funds move on-chain.<\/p>\n<p>Near One CTO Anton Astafiev said networks may struggle to know whether a transaction came from the real owner or an attacker. The team is preparing a testnet rollout using FIPS-204 quantum-safe signatures by the end of Q2 2026.<\/p>\n<h2 class=\"wp-block-heading\"><strong>NIST urges migration before threat arrives<\/strong><\/h2>\n<p>The U.S. National Institute of Standards and Technology has already <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.nist.gov\/news-events\/news\/2024\/08\/nist-releases-first-3-finalized-post-quantum-encryption-standards\" target=\"_blank\" rel=\"nofollow\">released<\/a> three post-quantum encryption standards. NIST said administrators should begin moving to the new standards as soon as possible because current encryption may face future quantum attacks.<\/p>\n<p>NIST also says organizations should identify where weak algorithms are used and plan upgrades to quantum-resistant systems. For crypto, that means wallets, validators, exchanges, bridges, and custody firms may need long-term migration plans before Q-Day becomes a real network risk.<\/p>\n<p>    <!-- .cn-block-related-link --><\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>CNN has renewed attention on Q-Day, the unknown future point when quantum computers may become strong enough to break common encryption systems.\u00a0 Summary Q-Day warnings renewed concern over encryption systems&hellip;<\/p>\n","protected":false},"author":1,"featured_media":10021,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-28867","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cryptocurrency"],"_links":{"self":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/28867","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/comments?post=28867"}],"version-history":[{"count":1,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/28867\/revisions"}],"predecessor-version":[{"id":28868,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/28867\/revisions\/28868"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/media\/10021"}],"wp:attachment":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/media?parent=28867"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/categories?post=28867"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/tags?post=28867"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
