It is a lengthy video so I solely skimmed some components and did not end it. The man would not absolutely perceive PoS as he thinks validators can put up invalid blocks which is not true. He is not an skilled within the topic he is arguing about so take his views with a grain of salt.
He appears to essentially worth proof of labor being associated to the bodily world whereas proof of stake is extra summary and that’s the place most of his argument comes from. That is opinion based mostly although as I personally assume being linked to the bodily world is a draw back of proof of labor as there’ll at all times be somebody larger than the miners in the actual world. E.g. if the US navy needed to take over bitcoin, they may do it simply.
With proof of stake being extra summary and digital, ethereum basically creates a digital ecosystem the place the ETH token is essentially the most safe token inside the ecosystem and you might want to take majority management of ETH to take over ethereum. The ethereum ecosystem creates its personal guidelines on who’s highly effective so is tougher to manage.
Secondly he hyperlinks proof of labor purely to electrical energy which is obtainable in every single place however he is lacking asics. One of many arguments he made was that if somebody had 60% of the stake they may take over the community however with proof of labor, folks might add extra hash energy to defend the community. Possibly in principle this might occur however in actuality, solely asics matter for hash energy so most individuals cannot defend the community in an assault. If somebody malicious had 60% hashpower it will be gameover for proof of labor as they may solely reference their very own blocks to forestall others receiving block rewards which might put different miners out of enterprise. Additionally asic manufacturing is extraordinarily centralised and if the folks constructing asics grew to become malicious they may take over the community.
