T= he difference here though is that Proof of Stake allows the quorum of coin = holders to block the exchange of said coins if they are going to a particul= ar destination. Nothing requires these staking nodes to include particular = transactions into a block. With that in mind, it isn't just that you re= quire the permission of the person who sold you the coins, which I can agre= e is a less dangerous form of permission, but you must also require the per= mission of at least 51% of the coin holders to even receive those coins in = the first place. This is not true in a Proof of Work system and this differ= ence absolutely should not be trivialized.

The idea that proof of stake is not permissionle= ss is completely invalid. It pains me to see such an argument here. Perhaps= we can come to an agreement by being more specific. I'd like to propos= e the following:

Premise: There is a healthy excha= nge market for PoS Coin X with tens of thousands of participants bidding to= buy and sell the coin for other currencies on the market.=C2=A0
=
If the premise above is true, then there is no significant p= ermission needed to enter the market for minting blocks for PoS Coin X. If = you make a bid on someone's coins and they don't like you and refus= e, you can move on to any one of the other tens of thousands of people in t= hat marketplace. Would you agree, Cloud Strife, that this situation couldn&= #39;t be considered "permissioned"?=C2=A0

If not, c= onsider that participation in *any* decentralized system requires the permi= ssion of at least one user in that system. If there are thousands of bitcoi= n public nodes, you require the permission of at least one of them to parti= cipate in bitcoin. No one considers bitcoin "permissioned" becaus= e of this. Do you agree?=C2=A0

Barrier to entry in PoW is matter for hardware and en= ergy is permissionless and exist all over the universe, permissionless=C2= =A0cost which exists for everyone no matter who because it's unforgeabl= e.

Barrier to entry in PoS is being given permission by = the previous owner of a token for you to have it via transfer or sale, both= choices they never have to make since there are no continuous=C2=A0costs w= ith producing blocks forcing it. A permission is an infinitely high barrier= to entry if the previous owner, like the premining party, refuses to give = up the token they control.

You're skipping the= part where you depend on a permission of a central party in control of the= authority token before you can produce blocks on your rasberry=C2=A0Pi.

Proof of stake is not in any possible way relevant t= o permissionless protocols, and thus not possibly relevant to decentralized= protocols where control must be distributed to independent (i.e. permissio= nless) parties.

There's nothing=C2=A0of releva= nce to discuss and this has been figured out long long ago.

You can send you= r participation keys to any malicious party with a nice website (see random= example [2]) offering you a good return.
Damn it's still Proof-of-S= quareSpace!

I believe we are talk= ing about a comparison to PoW, correct? If you want to mine PoW, you need t= o buy expensive hardware and configure it to work, and wait a long time to = get any return by solo mining. Or you can join a mining pool, which might u= se your hashing power for nefarious purposes. Or you might skip the hardwar= e all together and fall for some "cloud mining" scheme with a pre= tty website and a high rate of advertised return. So as you can see, Proof-= of-SquareSpace exists in PoW as well!

The PoS equi= valent of buying mining hardware is setting up your own validator and not o= utsourcing that to anyone else. So both PoW and PoS have the professional/e= xpert way of participating, and the fraud-prone, amateur way of participati= ng. The only difference is, with PoS the professional/expert way is accessi= ble to anyone with a raspberry Pi and a web connection, which is a much low= er barrier to entry than PoW.
