What is Ontology Gas?

ONG forms part of the decentralised Ontology ecosystem. Through the utilisation of a dual token protocol it fulfils the needs of the network ecosystem.

  • ONG is the utility token which drives on-chain services on the Ontology network.
  • This token was created to be used solely on the Ontology network, which is required as virtual ‘energy’ for using certain functions on the network.
  • ONG is rewarded to users who hold Ontology (ONT), over time more ONG will be generated until the circulating supply equals that of ONT.

By coexisting with Ontology, ONG aims to act as a strong support base for the potential growth and mass adoption of the Ontology network.
