Hm... Seems like the trust isn't as minimized as could be. Spark TM, the company, is the trusted party here.
And seems like they're pushing it for stables and tokens. 😮💨

No, it's not. Everything is opensource, you can create your own federation.
They allow stables and tokens but you don't need to use it if you don't want.
learning more RN. Presodio Bitcoin did a podcast on it. the operator, and spark provider and spark entity are all different. they are explaining that the provider side is closed source but in theory anyone with the high capability could also be one. interesting stuff
