All Sync Node operators are required to move to Ontology v3.1.5 as soon as possible, follow the official upgrade instructions, confirm full synchronization with Mainnet and verify normal node operation. Ontology said rapid adoption of v3.1.5 is critical to maintaining stable and uninterrupted synchronization across the restored network.
The restart does not end the security response. Ontology said it will continue monitoring network security, stability and performance while coordinating with technical and security partners on longer-term reliability. After the emergency pause and upgrade process, continued monitoring now becomes the main safeguard against further disruption as validators, node operators and ecosystem participants return to normal activity.
