Interesting project, getting bored with the names of these forks, though. Where's your imagination guys?
Waiting for more information about InstantTX -feature.
Are all transactions "private" transactions, or is those additional feature?
Good luck devs
SwiftTX: It works just like the "InstantSend" feature in Dash. When a user chooses to send a transaction as a SwiftTX, the transaction will be sent to Masternodes to process and it gets verified and guaranteed by them almost instantly.
Thus there is no need to wait for the transaction to appear in a confirmed block. This type of payment is made for Point of Sale situations in the real world.
Private transactions is an additional feature. You can choose to send all or some of your coins privately, or openly. If you want to remain completely anonymous with no way to track you or your payments, you can. If you don't care about your privacy and just want your recipient to receive the money in a second with a tiny fee, you don't have to use the private transactions feature. Although private transactions will be fast enough for most purposes and really low fee too.
