Crate bittensor_core 

The chain-defined compute core and native Rust SDK for Bittensor clients.

Rust owns the chain-defined pieces (crypto, SCALE, extrinsic payloads, metadata digests) and now also exposes a thin native client and semantic transaction executor over those primitives. Binding crates may reuse the same client or expose only the compute surface to another language.

See sdk/bittensor-core-spec.md for the full design.

Modules

client

Native chain access for the Rust SDK.

codec

SCALE encode/decode against a crate::runtime::Runtime.

digest

RFC-0078 merkleized-metadata: the digest signed via CheckMetadataHash and the type proof hardware wallets need to decode a transaction on-device.

error

The single error type crossing the core’s boundary.

keyfile_env

Pure environment password compatibility, without changing process variables.

keyfiles

Bittensor wallet keyfile encryption and JSON codec — compatible with the bittensor-wallet on-disk format (absorbed from py-sp-core).

keys

Substrate sp-core key primitives (absorbed from py-sp-core).

mlkem

ML-KEM-768 + XChaCha20Poly1305 sealing (the MEV shield), absorbed from bittensor-drand and rewritten as safe Rust (the old C ABI is gone).

pow

Public registration challenge mining. GPU drivers are optional and loaded at runtime; no signing material enters the miner or device memory.

runtime

Runtime: one immutable object per spec version, parsed from the raw MetadataVersioned bytes the transport already downloads and caches.

signers

Hardware and remote signing backends.

timelock

Drand quicknet timelock encryption (absorbed from bittensor-drand).

transaction

Semantic transaction planning and policy for the native Rust SDK.
