Ontology called it a preventive measure and said it had not confirmed a security incident or found any indication that user assets had been lost or compromised. Based on the project&#8217;s assessment at the time, its ONT and ONG crypto assets, along with other on-chain assets, remained unaffected.<\/p>\n<h2>Public node remained at block 20,770,893<\/h2>\n<p>Ontology&#8217;s first-party notice said it identified the potential concern during a daily security check. The notice did not specify the technical condition under review, which systems might be involved, or what findings would allow production to resume.<\/p>\n<p>The project said the suspension&#8217;s duration was undetermined and that it would issue a separate announcement before or when the network resumed. It also said it would not process on-chain transactions while block production remained suspended. Ontology did not disclose a public restart timetable in the notice.<\/p>\n<p>Those statements keep the episode distinct from a confirmed exploit or attack. The network interruption is clear, but the project&#8217;s asset-safety statement was a preliminary assessment made while the review was still underway. Ontology did not report a loss, compromise, or active attack in either of its initial updates.<\/p>\n<div class=\"cs-article-embed\">\n<p> <span class=\"cs-article-embed__related-reading\">Related Reading<\/span><\/p>\n<h3 class=\"cs-article-embed__title\">MANTRA Chain is back online, but silent code changes spark developer concerns<\/h3>\n<\/p>\n<p> <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\"> <i class=\"fa-light fa-arrow-up-right\"\/> <\/span> <\/div>\n<p>Ontology&#8217;s developer documentation lists dappnode1.ont.io as a public MainNet node.
