Read the OP bro and look at the preview for the new lite wallet, zk-SNARKs free video and voice calling, lite wallet for Android and IOs, and not even 2 months old, would like to see any other coin that has the innovation and progress SDC has, just remember zk-SNARKs was the talk of the town not long ago, everyone was saying DRK would be dead once it was released, well this month SDC will have it and it will be trust-less, need i say more, i hate talking about other coins here but you brought it up, i just looked at stealthcoin, i hold two coins and SDC is one that has everything they have for a while, not earth shattering not impressed.
People can already do video and chat with skype. That's a nice gimmick, but in terms of cryptocurrency usefulness, completely irrelevant.
zk-SNARKS would be cool if they weren't chronically vaporware. Frankly, without any hint from the team of how zk-SNARKs can be used to prove key ownership, one must be skeptical. There is absolutely no indication on this thread or anywhere else how the proofs will be implemented to anonymize transactions. I'd have a lot of SDC myself if there were. (If so, please link me to this info. I could be wrong, but I've looked pretty hard.)
I'll acknowledge that stealth addresses are
awesome. But they were in vertcoin first, so not terribly innovative for another coin to add, unless they are layered over other anon.
In fact, the only coin to do this is SSD. It combines Tor anon with stealth addresses (which the SSD dev calls "TimeVortex 2"). In SSD, stealth addresses are already included in the source and Qt. The stealth addresses in SSD won't be activated for a week or so, to give most users a time to upgrade. I think that this delay has to do with the fact the stealth addresses create a different kind of transaction than regular addresses and so everyone on the net needs to be running the same wallet so they don't get rejected.
Now, either Tor or stealth addresses alone are not innovative. However, together they are very powerful, and a completely new combination. As the stealth people point out, but have yet to deliver, the combination protects against block chain analysis and network analysis.
I'd say, given all this, that right now, SSD is the most anonymous coin. Period. Maybe SDC will catch up.
