InstantX may going to be our nuclear-weapon, if it gets implemented before dark and we get significant coverage in coindesk and other leading medias.
lol, you don't even have a network (let alone even structure of masternodes) and you're talking about IX. LMFAO.
All the functionality related to masternodes themselves (adding/removing masternode and masternode payments) will be there. Instant transactions may be not completely finished by that moment but I will try to make them ready.
Together with releasing source code I will write a long post which will describe in details how all of this stuff works, it will be reworked into a white paper in the future.
