Is there any legitimate reason one would have mult= iple >=20 > such dummy outputs?) None, but how about use of `SIGHASH_SINGLE` flag? If a dummy output is adde= d as the first, would it not require adjustment of the inputs of the transa= ction? In context you are discussing the transaction serialization, though, so per= haps `SIGHASH_SINGLE`, is unaffected? Regards, ZmnSCPxj
