here is my question again, if you can't answer then you is really something.
I just want to know if the current XC mixer is taking a few(2+) blocks to complete it transaction or just one(1)?
what is the meaning of "just one(1)? "
the current XC mixer is taking a few(2+) blocks to complete it transaction : yes
input --> block no 100 ----> output : 1 block / mixer can do this. never / why ? hard link. double spend / flowed operation / need step /
input --> block no 100
block no 101 ----> output : 2 block / double spend
It's all about bitcoin. Mixer is wallet + program(take in. send out)
