I gave you two of the best known examples of proof of stake that there are.
The Tezos team has done it and it's been running for about a year now. The Cardano team is doing it, and I'll link their paper below.
As far as Poelstra, that's a rather old document. A great deal of research has been done in the field since.
Cardano's paper:

- garmaine 8y agoNo new research can overturn the basic fact that proof of stake claims to do is impossible. It's perpetual motion machine. You can make proof of stake schemes more complicated, but it doesn't gain you actual security, just obscurity. You can't actually achieve the desired outcome of proof-of-work properties for a stake-based consensus mechanism. What has happened instead is that the basic / easy to analyze systems were broken, and so complications were added that defeated the simple attacks, but really just make attacking it more complicated. But there's no asymmetric advantage against attackers here -- a similarly complex attack can be made for any proof of stake scheme.
- jki275 8y agoIf you want to claim it's a perpetual motion machine, you're going to have to prove that claim. There are a whole lot of very smart people who disagree with you.
- garmaine 8y agoThe paper by Poelstra has details.
- jki275 8y agoI read it. It's old, and the issues in it have been addressed. There have been several years of research since that paper was released. I've pointed you to an academic paper that addresses the issues. I'm done with this discussion as you're simply repeating the same things over and over.
