According to CoinMeta, Ontology has temporarily suspended mainnet block production due to potential security vulnerabilities identified by the core development team during routine checks, resulting in a pause in on-chain transactions while validators conduct an emergency review. The official announcement from Ontology states that no security incident has been confirmed, and there is no evidence of user assets (such as ONT, ONG) being lost or stolen. The team indicated that block production will remain suspended until a thorough assessment is completed and security is confirmed to be restored.
