Binance will support the Ontology network upgrade and hard fork scheduled for August 21 at block 20,800,000, according to the exchange's announcement. The MainNet v3.1.2 upgrade is set to execute at 12:00 UTC.
Ontology, a layer-1 blockchain focused on decentralized identity and data, last completed a major upgrade in December 2025 when it rolled out MainNet v3.0.0. The v3.1.2 release represents an incremental step forward rather than a fundamental restructuring of the network.
During the upgrade window, Binance will suspend deposits and withdrawals for Ontology to ensure network stability during the fork. Spot trading of ONT will continue uninterrupted. The exchange's early confirmation of support removes a key operational risk for Ontology stakeholders and node runners preparing for the transition.

Ontology operates as an independent blockchain separate from the Ethereum Virtual Machine ecosystems that dominate institutional activity, though the network has historically pursued interoperability with other chains. The upgrade's timing in the fourth quarter aligns with the blockchain's typical maintenance cycle, with the prior v3.0.0 upgrade arriving roughly eight months earlier.
Network upgrades requiring hard forks demand coordinated support from major exchanges and node operators to prevent the chain from splitting. Major exchange backing for a scheduled hard fork typically arrives within one to two weeks of the upgrade date. Binance's announcement with specific block height and UTC time allows traders and node operators to plan wallet management accordingly.
