bittensor-core
The chain-defined compute core for Bittensor clients, as a single Python
extension module (import bittensor_core). Built from the bittensor monorepo
against the same crate revisions as the subtensor runtime itself.
What lives here (one rule): everything whose right answer is defined by the chain — sp-core key primitives (sr25519/ed25519, SS58), keyfile encryption/decryption, drand timelock encryption, ML-KEM-768, the SCALE codec and runtime-metadata engine, extrinsic assembly, and the RFC-0078 merkleized-metadata digest. Product decisions (intents, policy, CLI UX, transports) stay in the Python SDK.
This package replaces and supersedes py-sp-core and bittensor-drand.
Install
pip install bittensor-core
Wheels ship for manylinux (x86_64, aarch64) and macOS (arm64, x86_64); the sdist builds anywhere with a Rust toolchain.
Ledger support (LedgerDevice, HID) is compiled into every wheel. On Linux
the HID transport talks to hidraw directly (no libudev, no C), so the
manylinux wheels carry it too; you only need the usual
udev rules so the device is
accessible from userspace.
Development
The Rust logic lives in the sibling bittensor-core crate; this crate is
bindings only. Build a development wheel from the repo root:
uvx maturin develop -m sdk/bittensor-core-py/Cargo.toml
