The way @fountain_app distributes the sats could be replicated. For every sats the parent loads into the wallet, the wallet devs get 1%/2%, the educator who made the material avalible get 3%/5% and the kid get the rest. As a parent you can choose what will you add sats rewards to, and anyone can create educational material. NOSTR web of trust with a raputation score plus the parebt proof of work of looking into the material before loading the awards, and even the parent ability to block specific contenr to their child culd create really nice incentives.
