Module derive 

The SDK’s one address derivation.

An address is the truncated hash of an identity key, so anything carrying both is self-certifying: a recipient re-derives and compares rather than consulting a directory. Every trust gate in the protocol is that comparison, which is why there is exactly one implementation of it and why it lives where both a phone and a leaf node can reach it.

Constants

ED25519_PUBLIC_KEY_LEN

Length of an Ed25519 public key, in bytes.

Functions

derive_address

Derives the canonical self-certifying address of an Ed25519 identity key: off1…, the bech32m encoding of 0x01 ‖ SHA-256(public_key)[..20].
