BLS signatures are great. They are really valuable when doing multi party signing.
Schnorr signatures take more communication between parties.
The Schnorr implementation on bitcoin cash would save Dash space on chain. I believe it is safe. A Schnorr signature can use the same addresses and keys. Since the Bitcoin cash Schnorr implementation is not multi party my dislike of Schnorr does not apply.
BLS sigs could be used for payments that would require different addresses. Just make sure to gaurd against the related key attack. BLS for payments would have simmilar savings as Schnorr would. BLS for payments would have HUGE multisig advantages.
anything in this post touching transactions is a hard fork.
DCG should focus on platform!
