Awesome. Briefly speaking our token would be used as
a) reward for working on social impact (from ideation to realization)
b) bearer of curation rights to detrmine the value of actions for social impat
c) instrument for donations and investments
d) payment token on a marketplace for services and goods
We've already done a lot of caluculations on our token economics. Concerning the technical part we thought we could rely on the SMTs. Now we'll have to recheck that. So, it'll be very interesting to learn about steem-state and Engine.
