A 32-byte Blake2b256 hash output.

BCS

A Digest's BCS serialized form is defined by the following:

digest = %d32 32OCTET

Due to historical reasons, even though a Digest has a fixed-length of 32, IOTA's binary representation of a Digest is prefixed with its length meaning its serialized binary form (in bcs) is 33 bytes long vs a more compact 32 bytes.
