The first app on any smart contract platform is money (h/t @punk4156)

A good money (for SoV) has a number of measurable characteristics —most important is predictable, deflationary supply. Others include, gini, decentralization, yield, lindy, (what else?)

Deflationary supply is something that most smart contract do not currently have. Begs the question: what needs to change for that to be untrue?
