Use OnFinality for Bittensor RPC endpoints, API access, dedicated Bittensor nodes, validator infrastructure, and TAO mining workloads. OnFinality supports Bittensor teams that need reliable RPC access, archive and trace capabilities, node monitoring, and a path from shared RPC APIs to dedicated infrastructure.

What is Bittensor?

Bittensor is a decentralized network that connects computers worldwide to collectively develop and improve artificial intelligence. Unlike traditional AI development controlled by a single company, Bittensor enables distributed participation through two primary roles: miners and validators. Miners contribute AI models or computing power, while validators assess the quality of miners' work. Both roles earn TAO, the network's native cryptocurrency, as rewards for their contributions.

Bittensor aims to democratize AI development by allowing anyone with a computer to participate, fostering diverse and innovative AI solutions beyond the reach of big tech companies.

Bittensor RPC Endpoints

A Bittensor RPC endpoint is a network URL that applications use to read blockchain data, submit transactions, and connect backend services to the Bittensor network. OnFinality provides managed Bittensor RPC endpoints via Substrate JSON-RPC over HTTP and WebSocket transports. These endpoints are suitable for production dApps, wallets, DeFi products, analytics tools, games, bots, and backend services.

Dedicated Bittensor Nodes

For teams requiring higher capacity, consistent performance, or validator infrastructure, OnFinality offers dedicated Bittensor nodes. Dedicated nodes provide exclusive access to a node instance, eliminating resource contention and enabling custom configuration. They are ideal for TAO mining operations, validators, and high-traffic applications.

Archive and Trace Support

Bittensor on OnFinality supports archive and trace capabilities, allowing developers to query historical state and debug transactions. Archive nodes store the complete chain history, while trace APIs enable detailed execution analysis. Availability depends on plan and network configuration.
