Under the same conditions, PoS is more secure. According to the data of crypto51, a 1-hour 51% attack on Ethereum will theoretically cost $1,298,172, while the figure will rise to a staggering 61,573,290 ETH when it comes to Ethereum under PoS.

The system under PoS is easier to recover after being hacked. Under PoW, by contrast, if the hacker’s mining hardware manages to launch a 51% attack on Bitcoin, the Bitcoin network will fork and thus cannot resist subsequent attacks; yet “slashing penalties” in the PoS blockchain means that the hacker’s funds will be largely burned so that he cannot make another attack.

PoS staking is more decentralized than PoW mining. The restrictions of PoW mining conditions bring the majority of mining rigs to a few large mining farms. By comparison, PoS staking just requires ordinary personal computers or even mobile phones.
