Barrier to entry in PoW is matter for hardware and energy is permissionless and exist all over the universe, permissionless cost which exists for everyone no matter who because it's unforgeable.
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 costs with 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 Pi. Proof of stake is not in any possible way relevant to permissionless protocols, and thus not possibly relevant to decentralized protocols where control must be distributed to independent (i.e. permissionless) parties. There's nothing of relevance to discuss and this has been figured out long long ago. https://github.com/libbitcoin/libbitcoin-system/wiki/Proof-of-Stake-Fallacy https://medium.com/@factchecker9000/nothing-is-worse-than-proof-of-stake-e70b12b988ca On Tue, Jun 15, 2021 at 7:13 AM James MacWhyte via bitcoin-dev < bitcoin-dev@lists.linuxfoundation.org> wrote: > > @Lloyd wrote: > > Of course in reality no one wants to keep their coin holding keys online >> so in Alogorand you can authorize a set of "participation keys"[1] that >> will be used to create blocks on your coin holding key's behalf. >> Hopefully you've spotted the problem. >> You can send your 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-SquareSpace! >> > > I believe we are talking about a comparison to PoW, correct?
