public class BLS12_381SerializationTest
extends junit.framework.TestCase

Tests for the Zcash-format compressed serialization of BLS12-381 G1 and G2 points. The G1 generator hex is the well-known constant published in the Zcash spec (and reused by Eth2 / Filecoin / IETF draft-irtf-cfrg-pairing-friendly-curves).
