Subtensor
Project Links
Description
Subtensor is the open-source Substrate-based node software implementing the Bittensor blockchain. It runs the Yuma Consensus mechanism, records TAO balances and transactions, stores neuron metadata for miners and validators, and supports WASM smart contracts through pallet-contracts. Node operators can run a lite node using warp synchronization or an archive node that maintains full chain history. Subtensor also embeds an EVM runtime layer with mainnet Chain ID 964.Category: Node Software
Bittensor SDK
Project Links
Description
The Bittensor SDK is an open-source Python library for programmatic interaction with the Bittensor network. It provides tools to create and manage wallets, register miners and validators, write subnet incentive mechanisms, query network state, and submit transactions to the Subtensor blockchain. The library uses a dual-key wallet model with a coldkey for secure TAO storage and a hotkey for operational tasks.Category: Developer Tooling
Bittensor CLI
Project Links
Description
The Bittensor CLI (btcli) is a command-line interface for managing operations on the Bittensor network. It provides commands for wallet creation and encryption, TAO transfers and staking, subnet and neuron registration, subnet hyperparameter management, on-chain governance participation through Senate proposals, and network status monitoring. It is installable via pip, Homebrew, or from source.Category: Developer Tooling
Bittensor Metadata Portal
Project Links
Description
The Bittensor Metadata Portal is a self-hosted web interface operated by the Opentensor Foundation that provides current Bittensor network chain metadata and specifications. It enables Polkadot Vault cold storage device users to scan QR codes to add Bittensor chain specifications or update network metadata on their devices.Category: Developer Tooling
Bittensor EVM Bridge
Project Links
Description
The Bittensor EVM Bridge is an interface operated by the Opentensor Foundation for moving TAO between Substrate-style SS58 wallets and Ethereum-style H160 wallets on the Bittensor network. Users can transfer TAO to access the EVM execution environment on Bittensor or convert TAO into vTAO for bridging to other EVM-compatible networks.Category: Bridge
