2. use of your blockchain as a payments system

Ok, here there is slightly more to work with. A blockchain CAN work as a payments system because it can transfer value from one holder to another. However, what are we competing with ? Legacy payments systems which are already inuse, therefore the blockchain would have to deliver some kind of substantial advantage to be adopted. Lets look at the properties that a payments system needs to be attractive to large scale commercial adopters:

 • agnostic (it should be able handle any currency denomination)
 • fast (typically processing a single trade in 2-3 seconds)
 • easily reversible (if the cashier rang my brussel sprouts through on the other guy's bill by mistake they should be able to credit them and charge me within a few seconds)
 • both locally and globally scaleable (i.e. if my business needs more capacity it should be able to add servers to get it. If the network as a whole needs more capacity it should have recourse to growing infrastructure to gain capacity at least linearly with invested capital)
