Careful. "Pure POS" is a "pure piece of shit".
There is a reason that real projects like Ethereum are taking a long time to get this right.
Proof of stake protocols are vulnerable to two major issues:
There is no consensus protocol that really fully addresses both of these problems. Tendermint is pretty close but Ethereum's Casper is designed to value availablity more than consistency.
Soooooo long story short, this is a whole load of crap unless they can solve those problems.
Casper and Ethereum are close but PoS is still rather untested.
Thanks for adding clarity here, Kyle. I was unaware of the general problem with POS you've explained.
Cheers!
There are a lot of nuances when dealing with consensus protocols.
Be sure to read Vitalik's blog posts on the matter. He does a fantastic job of explaining exactly what I am talking about. I don't think I could write something as succinctly as he can.
Is there any minimum amount of coins for stake in pos?
I have the same question, were you able to get and answer?
Casper is going to change the playing field. Might even knock BTC down a peg or two... I'm confident the flippening will still happen but maybe the schedule has changed a bit.
Casper is hopefully going to enable real on chain scaling and the sharding needed for the future.
Keep in mind that PoS and PoW are not interchangeable. There is a reason that BTC will and always should stick to PoW.
You can't mess with entropy. The world needs one entropy based store of value.
pardon my lack of knowledge, but what is "Casper"?
