Ontology Halts Mainnet Block Production Over Potential Security Concern

The pause prevents state changes while validators and partners run a security review that could lead to software fixes before the chain is restarted.

Overview

  • Ontology’s core developers stopped mainnet block production as a precaution after a routine security check flagged a potential issue, leaving on‑chain transactions unprocessed.
  • The network says there is no evidence that ONT, ONG, or other user assets have been lost or compromised so far.
  • Some exchanges have already suspended ONT and ONG activity tied to the chain, which has frozen deposits and withdrawals for wallets holding assets on the paused mainnet.
  • Ontology is working with validators and ecosystem partners on an emergency review but has not disclosed technical details or whether a software upgrade is required.
  • The pause affects wallet users who need on‑chain confirmations and could require coordinated upgrades and a validator vote to resume, with the team advising users not to move tokens until the network announces a safe restart.
