Ontology is a high performance, open source blockchain specializing in digital identity and data. Ontology's infrastructure supports robust cross-chain collaboration and Layer 2 scalability, offering businesses the flexibility to design a blockchain that suits their needs. With a suite of decentralized identity and [data sharing protocols](https://coinmarketcap.com/alexandria/article/a-guide-to-self-sovereign-identity-a-deep-dive-by-ontology) to enhance speed, security, and trust, Ontology’s features include ONT ID, a mobile digital ID application and DID used throughout the ecosystem, and DDXF, a decentralized data exchange, and collaboration framework. Ontology adopts a dual-token model, with both ONT and ONG as utility tokens. Ontology decouples ONT and ONG to alleviate the risk of turbulent fluctuations of the native “asset” value on the gas fee. ONT is used as the staking tool and the time, cost of staking and operating costs of the nodes are considered to be inputs. ONG is used as a value-anchoring tool for on-chain applications and is used in the transactions on the chain.
