InstantX is a powerful thing. Can be very dangerous for DRK if someone could misuse it before it mature
If that is the case, I seriously see that as an attack vector. I dont know, I'm no cryptographer.
A tx can only be confirmed when the block is solved, so I do see your reasoning. Its the "locking" part I dont get. Once a tx is boradcast and hits the blockchain, you can't roll back (loool, unless its Vericoin).
So if the MN ping each other to validate the same tx is being broadcast, anyone with a huge chunk of nodes can subvert InstantX. In this case, it is possible to perform a 51% attack.
I'm sure this is not the case, Evan is a smart cookie.
I thing 51% attack will not work with instantX. We don't yet know where the attacks will come from cos this is something new. This is great and need to be checked painstakingly cos after 20-30 seconds coins can be sold.
