...I wonder how you can have so much transactions per second? (the slide shows 500-1500) I read that bitcoin is limited to 7 transactions per second...
My thinking goes this far. Instant Transactions will have the input funds locked by a set of 10 masternodes chosen deterministically. There are 3,500 masternodes. Therefore 350 (3500/10) Instant Transactions (minus overhead) can be locked simultaneously. If this process can happen a couple of times every second, then 500-1500 is the answer.
If there are any devs watching that want to correct me, please do.
