Ontology has temporarily halted mainnet block production after its core developers identified a potential security concern during a routine check, leaving on-chain transactions suspended while validators conduct an emergency review.
No Confirmed Security Incident
No security incident has been confirmed, and the team said it has found no evidence that ONT, ONG or other user assets have been lost or compromised. Ontology described the halt as a preventive measure, distinguishing it from a response to an active attack or confirmed theft. The team has not disclosed the technical nature of the potential security concern or which component triggered the review.
Transactions Remain Suspended
With block production stopped, transactions submitted to the Ontology mainnet cannot be processed until network operations resume. The team has not provided an estimated time for restart and said the review will take priority over restoring the chain quickly. Users have been advised against attempting time-sensitive on-chain transactions while the pause remains in place.
ONT and ONG Dual-Token System
Ontology operates with ONT and Ontology Gas (ONG) as its two native assets. ONT is used within the network's governance and staking structure, while ONG serves a separate role in its economic model. The network reduced its minimum staking requirement from 500 ONT to one ONT as part of a governance update. Ontology's architecture has historically focused on decentralized identity and data infrastructure, using ONT ID for identity management.
Network Pauses as Preventive Measure
The Ontology team has chosen to keep transaction processing offline while the potential issue is examined instead of allowing normal block production to continue during the investigation. The chain is intentionally unable to process transactions, but Ontology has not reported an exploit, unauthorized asset movement or an ongoing attack. Normal block production will resume only after the network has been assessed and deemed safe to operate. A separate announcement will be released before or when block production resumes.
