The Ontology mainnet has suspended block production due to a security review, and user assets have not been affected

According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.

During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.
