An introduction to Ontology nodes

Ontology nodes

While there are different types of networks, there are different types of nodes as well. Find the list below.

  • Triones node | Ontology MainNet

    • Triones nodes are bookkeeping nodes that participate in the network consensus, and must be voted in by user staking of ONT, after applying to be a consensus node. More information on Ontology consensus can be found here.

  • Synchronization node | Ontology MainNet / Polaris TestNet

    • Synchronization nodes do not participate in network consensus, and only synchronizes the blocks generated by the Triones (bookkeeping) nodes.

  • Single node | Private TestNet

    • Ontology supports single node network deployment for the development in private test environments.

Ontology CLI

A fully featured command line interface for creating, managing, and interacting with Ontology network nodes.


  • Setup a node on the Ontology MainNet, Polaris TestNet, or private TestNet

  • Manage the nodes RPC, REST, and WebSocket sub-services

  • Configure node parameters such as network gas fee price and transaction limit per block

  • Run and manage an Ontology MainNet consensus node

  • Account and asset management

  • Multi-Signature account creation and transaction signing

  • Query block and transaction information

  • Smart contract deployment and invocation

Network environments

Ontology blockchain network consists of both a public live and public test environment. Developers also have the choice of deploying a node in a private test environment.

  • Ontology (MainNet): public live environment

  • Polaris (TestNet): public test environment

  • Private (TestNet): private single node network and test environment
