Essential Primitives


Hashes provide succinct commitments to arbitrary data.

Hash(message, key) denotes a keyed BLAKE2b-256 hash.

Hash(message) denotes BLAKE2b-256, the default case when the key is empty.

Substrate primitives (i.e., block hashing) use BLAKE2b-256 as well.

Digital Signature

Digital signatures secure different parts of consensus by providing a means of authentication. Currently, we use Schnorr (with the schnorrkel library).
