Does/can this implement the Boneh/Drijvers/Neven BLS signature scheme? Or does this require extra steps to protect against rogue key attacks?

See https://crypto.stanford.edu/~dabo/pubs/papers/BLSmultisig.html

It describes an efficient BLS multi sig as well as a scheme resistant to rogue key attacks.
