Bitcoin currently handles 7 unconfirmed tx per second + confirmation/waiting time
DASH handles 10 confirmed tx per second and you can walk out the shop with the merchant safe and happy.
Not quite right, the
entire Bitcoin network handles a maximum of 7 txes per second. Each IX only requires a tiny subset of the 3000 MN total to work. You're looking at tx throughput two orders of magnitude+ better than BTC, each one in seconds, not minutes/hours.
So if the subset is 10 for example, at 3k M-Nodes the TPS would be 3,000 as well, I assume? That's 1k more than VISA handles atm.
This is a very interesting read on that matter:
