Commitments(outPK) are required when doing a MLSAG signature. However, there is no outPK in a type 0 transaction. example
What should I do as facing this kind of transactions? I've checked rctSigs.cpp but still don't get it..
Sorry for the implicit information.. I mean that I'd like to make a tx and some of the outputs are type 0 like this (the number 4/6/9/10 are types 0).
I am curious how to do MLSAG with vins which have no commitments because commitments(OutPk) are required for building a tx.
