What is Ontology Gas (ONG)?

Deep Dive

1. Purpose as Network Fuel

ONG's primary role is to facilitate on-chain activity. Every transaction, smart contract execution, and data exchange on the Ontology blockchain requires ONG to pay gas fees. This design ensures network security and prevents spam by attaching a cost to operations. By decoupling this utility from the governance token (ONT), Ontology aims to provide more stable and predictable transaction costs, insulating users from the price volatility of the main staking asset.

2. The Dual-Token Model Architecture

Ontology employs a two-token system. ONT is used for staking, consensus, and community governance. ONG, generated through a continuous emission, is dedicated solely to operational costs. This separation means that the cost of using the network (payable in ONG) is not directly tied to the market value of the staked asset (ONT). The tokenomics were refined in 2025 when the community voted to permanently cap the total ONG supply at 800 million tokens, burning 200 million to create a more predictable, deflationary model (Cryptopotato).

3. Role in a Digital Identity Ecosystem

ONG's utility extends beyond simple transactions into Ontology's flagship use cases. The token is integral to platforms like ONT ID, a decentralized identity framework, and ONTO Wallet, which is evolving into a data monetization hub. In this ecosystem, ONG could be used for micro-payments related to verifying credentials, sharing data, or accessing services, positioning it as a key enabler of user-controlled digital identity and sovereign data economies.

Conclusion

Fundamentally, Ontology Gas is the operational lifeblood of a blockchain built for trust, enabling secure transactions and powering a growing suite of identity and data tools. As Ontology's roadmap focuses on integrating AI and data sovereignty, how will ONG's utility evolve to facilitate a user-owned data economy?
