According to CoinMeta, the official of the established public chain Ontology stated that they received an urgent report indicating that a certain project on the chain may pose a security risk or threaten the security of network assets. To prevent potential risks, Ontology has coordinated with most consensus nodes to temporarily stop bloking in order to cooperate with the investigation. The investigation is still ongoing, and bloking will resume once safety is confirmed. The official has not disclosed the name of the project involved or the specific risks, nor has it been confirmed whether there has been any asset loss.
