Hey guys, I am curious about this programmable nature of Bitcoin that i am seeing at minute 3:00 in this video:
https://www.youtube.com/watch?v=YIVAluSL9SUFrom what they said there, you could program every single Satoshi to act as a token that could only be spent only where you want it to spend. For example programming Bitcoin to be available just for healthcare, or programming them to come back to you if your receiver doesn't spend them or a ton of other things. It sounded amazing but I am never seeing or hearing about this aspect of Bitcoin elsewhere. Is it some kind of Bitcoin functionality that was lost along the way or what exactly?
