Expand description
(spec link) A cryptographic hash function that takes as input an arbitrary octet string and returns a point on an elliptic curve. Functions of this kind are defined in hash-to-curve-spec.
Note: given we’re using the “minimal-pubkey-size” variant of the spec, this function must output a point in G2.
XXX: this function doesn’t take DST as an argument in the spec. It should!
