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 chains do not currently have. Begs the question: what needs to be true for that to change?
