Module threshold_bip32 

Threshold BIP-32 HD key derivation.

BIP-32 hierarchical deterministic key derivation in the threshold setting. Each party derives child key shares without reconstructing the parent key.

Structs

DerivationPath

A BIP-32 derivation path.

PathIndex

A derivation path component (index + hardened flag).

Functions

derive_child_scalar

derive_party_share

Each party in a threshold quorum derives their child share independently. Since derivation is deterministic, all parties at the same path index derive consistently.

derive_path

Derive a scalar from a parent following a full path.
