A single forged mint wallet moved 2.385 trillion ONE through 477 successful transfers in just 106 seconds, illustrating how quickly the counterfeit supply spread once the flaw was exploited.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Harmony said it weighed less disruptive fixes before settling on a full rollback. Burning or repairing the forged tokens directly was ruled out because they had already scattered across exchanges, decentralized exchange pools, contracts and countless wallets, meaning removing them at each destination risked catching legitimate holders in the process. A blacklist approach and selective transaction replay were dismissed for similar reasons \u2014 both risked either leaving forged supply in circulation or producing a chain state that no longer matched what users had already confirmed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under the plan, validators would retain the chain up to specific checkpoints on shard 0 and shard 1, both recorded shortly before midnight UTC on August 11, and new blocks would begin from those points once client version v2026.1.2, configured to reject the exploit&#8217;s underlying flaw, is adopted network-wide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical effect on the attacker&#8217;s actual proceeds is likely limited. Most of the forged tokens are believed to have already moved off-chain through exchanges before the rollback plan was announced, meaning a rewind mainly clears remaining counterfeit supply from the ledger while also erasing transactions that ordinary users made in good faith after the exploit \u2014 a trade-off that has drawn comparisons to earlier rollback debates on other networks this year.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For traders and holders of <strong>ONE<\/strong>, the coming days carry two separate risks: continued price pressure as the token digests the exploit, and operational uncertainty for anyone who transacted on Harmony between the exploit and the proposed rollback point, since those transactions could ultimately be reversed. Exchanges and bridges are reportedly assisting with the investigation as the network moves toward a coordinated restart.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Harmony is preparing to roll its blockchain back to a pre-attack checkpoint after an exploit let an attacker<\/p>\n","protected":false},"author":2,"featured_media":536,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[4],"tags":[],"class_list":["post-535","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-altcoins"],"brizy_media":[],"_links":{"self":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/535","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=535"}],"version-history":[{"count":1,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/535\/revisions"}],"predecessor-version":[{"id":537,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/535\/revisions\/537"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/media\/536"}],"wp:attachment":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=535"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=535"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=535"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
