> The difference is that PoW is permissionless and PoS is permissioned system.

This is a big statement without an argument to back it up.

> PoS is simply worse from every angle and it’s also not cheaper because MR=MC.

The difference is that MC in PoS is mainly interest costs, while in PoW it's energy and hardware.

PoS is permissioned system because if you want to become a validator you must convince another (potential) validator to give up part of his stake.

> MC in PoS is mainly interest costs

no, it's also costs of fighting (via politics, marketing and hacking) for that initial pre-mined stake.

it's not cheaper than PoW and has worse security properties due to all sorts of attacks - long range, grinding, etc. ultimately it's flawed because unlike in PoW there is no universally objective measure of geniuneness of a chain (the "work" in PoW).

PoS is effectively permissionless given the number of parties that have the stakeable asset and are willing to sell it.

>>no, it's also costs of fighting (via politics, marketing and hacking) for that initial pre-mined stake.

There is no fight if there was a transition from PoW to PoS, and thus no premine, or if the premine was distributed via an open crowdsale, with revenue allocated to a non-profit foundation.

Your analysis makes too many tenuous assumptions to push one side of the debate.

the market doesn't have enough liquidity for you to gain a meaningful stake and those that organized the pre-mine scam will always remain in control. or they will sell you the stake for exorbitant price and perform a long-range attack against you because they still hold the original keys.

Eth is going through transition and yet it’s the largest pre-mine scam in existence.

Crowd sales are just pre-mines.

Non-profit is just pre-mine beneficiary that people will fight for control over.

And you conveniently ignored all the other problems with PoS: long range and grinding attacks, no ability to reduce power of malicious staker, no universal objective measure for which chain is genuine so you have to rely on third parties, etc.

>>the market doesn't have enough liquidity for you to gain a meaningful stake

This is unsupported. There are billions of dollars worth of ETH sold every day. If you intended to hold what you bought, the liquidity would gradually go down as you took what was bought off the market, but you could certainly acquire a significant share of the stake.

>>Non-profit is just pre-mine beneficiary that people will fight for control over.

That assumes zero altuistic oversight from ETH stakeholders at large deterring attempts to corrupt the grant issuing process, which is not a sensible assumption.

>>And you conveniently ignored all the other problems with PoS

Long-range attack is addressed with dependence on weak subjectivity:

The rest of your criticisms have similarly been addressed in state of the art Proof of Stake protocols, in particular for ETH 2.0 PoS.

not nearly enough to purchase a meaningful stake that could protect you from premine scammers that launched the project. not to mention - you'd be giving up your money for their benefit. double rekt.

> zero altuistic oversight from ETH stakeholders at large deterring attempts to corrupt the grant issuing process, which is not a sensible assumption

ah, nice, a system that simply relies on altruistic motives of premine scammers that will be in control and largest beneficiaries of those staking grants. what could possibly go wrong.

> Long-range attack is addressed with dependence on weak subjectivity: ... The rest of your criticisms have similarly been addressed in state of the art Proof of Stake protocols

it's not addressed, it's just partly waved away and partly obfuscated in a non-solutions like slashing or checkpointing.

pos still doesn't work, pow is the only known decentralized and trustless consensus reaching protocol.

There is no need for any protection. Proof of stake doesn't enable stakers to attack non-stakers. Nor would stakers have any incentive to.

Moreover, there was absolutely no scam in the premine. It was publicly announced, and the majority of it was distributed via a programmatic crowdsale.

This characterization of yours is simply an emotional attack.

>>you'd be giving up your money for their benefit. double rekt.

Same with any currency. You provide something of value to acquire some currency. This applies to dealing with early adopters of other currencies, early investors in companies, etc.

This is simply a bad-faith criticism of proof-of-stake that is equally applicable to anything else, unless you make the tortured argument that a publicly announced crowdsale and dev grant is somehow a "scam", and therefore there is some distinct quality about buying currency from those who acquired their stake through a premine over acquiring it through some other method.

>>ah, nice, a system that simply relies on altruistic motives of premine scammers

How can any one can take ETH's critics seriously when you make blatantly libelous accusations that participating in an open premine crowd makes someone a scammer.
