- Proof of Stake is not as secure as Pow because the blockchain is not anchored in the outside world through the consumption of an external resource. In PoW this resource is Electricity, which makes sure that it is very very expensive to attack the blockchain and makes this attack economically unrewarding. Using energy burnt to back a block allows us to view immutability objectively. Whereas any non-energy-based method ultimately requires someone’s subjective interpretation of immutability. By attaching energy to a block, we give it “form”, allowing it to have real weight & consequences in the physical world. And PoS also leads to centralization as the power is concentrated with the people who have the most money. The entrance barrier to staking is 32 ETH, this is a fundamentally different system as PoW where miners compete throught the use of energy (cost) with each other. I personally consider Ethereum's economics broken at the base layer.
Concentrated with the people who have the most money is too a problem with a pow network, or?
Only the people who have big money to buy asic miners and cheap electricity earn by mining and centralization is also limited to a few pools.
The higher eths price increases, the more expensive it becomes to attack it in a pos system.
Maybe im missing the experience, but thats how i would see it.
