InstantX stands for "instantaneous transactions" and is the technology that enables transactions to be fully confirmed in only four seconds. InstantX utilizes the 2nd rate of the Dash network (Masternodes) to generate a "lock" once a deal is produced on the network. The DASH involved in that deal are locked as well as could not be double-spent; the network will deny any kind of efforts to spend the secured DASH again. I thought this should be included under Dash Mining. It was shocking to me that this is not available in forum. Cheers!
