Hmm... I hear what you're saying, and in a way you're right... it is in lots of places, but all the instances of the steem blockchain are the same, and that's what everyone mining has a copy of. So I think it's right. Thanks for checking me, tho.
That take is based on my interview with one of the founders and my broader reporting on this sector, so I'm pretty confident about it.
But you're right that it's copied so many places that it's kinda weird to say it's one place... one entity or object, I guess
