If i can get the source code, maybe we can bring this to life, but I don't know if the dev who developed the tattoo blockchain still have it, which is not "tattoodev". If I can get it we can start from there, also as I'm not a developer we will need one.
If the dev is not "tattoodev", would it be "daidaneg"? I remember that I had a slack chat with "tattoodev" months ago (or, was it years?) And he mentioned that daidaneg was in charge for financial and payments. At least he'll know some people from the team?
