What is Ontology Gas (ONG)?
Ontology Gas (ONG) is the utility token of the Ontology blockchain, a high-performance network focused on digital identity and data integrity. Launched in 2018 by Li Jun and the Onchain team, the platform uses a dual-token model. ONT (the other native Ontology’s token) serves governance, while ONG functions as the network’s "gas," serving as the primary medium for executing smart contracts and anchoring the cost of on-chain operations.
The total supply of ONG is capped at 1 billion tokens, released over 22 years to ONT stakers. This steady distribution ensures a consistent supply for those who buy Ontology Gas.
- Key and unique features of the ONG token:
- Transaction utility: Every smart contract and transfer requires ONG for fees.
- ONT ID Power: It facilitates decentralized digital identities.
- Staking dividends: ONT holders receive ONG as a reward for securing the network.
- Stable costs: The dual-token system keeps transaction prices predictable.
