Nope,
right now xspec is just an empty promise. Where is the white paper, where are the technical details... where's the math that proves they solved anonymous staking...
If they had it, they would show it, because that would make the price skyrocket, and that is after all all they want...
Right now, buying xspec is like buying a toyota at double the price, because the vendor promises you that it will become a lamborghini in the future...
This is pure vapourware. If they would have the math, they would show it, not hide it...
best regards
v2.0 that releases stealth staking will be available in Q2 2018. I actually spoke to one of the devs in the last hour and he told me this: the algorithms that facilitate stealth staking will not be made public until the release of the ghost paper, shortly before the release of v2.0 The reason for this is that if they made the math behind stealth staking public now, a few months before they release stealth staking, anyone could come and steal their project! It would be crazy to release the math this early.
