I think it would be cool if there were some sort of currency kids could use in exchange for screen time. Giving real money to kids as a reward has always been a bit iffy. What are they going to spend it on? Candy? Video games? Screen time would probably be better since its something they’re going to consume multiple times everyday, but also something parents want to control. Instead of giving them cash for completing chores, or getting good grades, give them something they could exchange for screen time. Let them earn interest accumulated screen time, or trade it away to their siblings. That’ll help them build some basic financial sense without them actually holding currency your family might need. Would this need a blockchain? I’m not sure. I imagine a single company trying to do it wouldn’t go so well since there’s so a couple closed off ecosystems out there (ie Apple), and collecting data on children has legal problems.
