📝 Original message:Proof of stake is permissioned by coins, an internal, permissioned, and
already owned resource.
You cannot gain tokens without someone choosing to give up those coins - a
form of permission. Permission can also be thought of as an infinite
barrier to entry.
PoW forces giving up control through both permissionless to enter mining
via EXTERNAL permissionless resources and unforgeable costliness for the
miners.
Without unforgeable costliness there's no reason to ever give up control in
PoS.
In fact, staking quite literally incentivizes keeping control by rewarding
those in control with more coins and control in perpetuity at no cost - the
incentives on PoS are completely backwards from decentralizing control.
Since no mechanism forces control to be permissionlessly distributed to
others, parties in control cannot be considered independent parties nor can
control be considered decentralized.
PoS solves nothing that's relevant to permissionless decentralized networks.
> In the following years we'll be seeing proof of stake being implemented
It has been implemented since 2014 but it doesn't meet criteria for a
permissionless network. There's nothing new about implementing permissioned
networks.
You could try to replace proof of work with proof of bitcoin burn (not well
studied) on blockchains other than Bitcoin, but there's no known
replacement for proof of work for Bitcoin right now.
PoS has been considered and studied since then many times since then and
dismissed repeatedly for irrelevance to decentralized permissionless
technology, examples:
