Learn more about PoS

“All you require is a standard PC” is not the full story. You still need to invest some money. In PoS, you propose an internal resource—cryptocurrency—rather than an external one (such as hardware or electricity). Every protocol has its own set of rules, but generally speaking, in order to be eligible for staking, you must hold a certain minimum quantity of money.

After that, you secure your money in a wallet so that it cannot be changed while you are staking. Usually, you and the other validators will agree on which transactions should be included in the upcoming block. You could say that you're making a wager on the block that the protocol will pick.

Depending on your stake, you will receive a share of the transaction fees if your block is chosen. You stand to gain more if you have more money locked up. However, if you make an effort to defraud by submitting fraudulent transactions, you could lose some or all of your interest. As a result, we have a mechanism that is comparable to PoW: being honest is more profitable than being dishonest.

Typically, the compensation for validators does not include newly minted coins. Thus, another method must be used to issue the native money of the blockchain. This can be accomplished either by an initial distribution (such as an ICO or IEO) or by launching the protocol with PoW before switching to PoS later on.

Pure versions of Proof of Stake has primarily only been used in small-cap coins up until now. As a result, it's uncertain if it can be a practical replacement for PoW. Although it seems reasonable in theory, it will work completely differently in actuality.

When PoS is implemented on a network with significant value, the system turns into a game with financial incentives. The only way to determine whether it is possible is on a live network because anyone who has the knowledge to "hack" a PoS system is probably only going to do so if they stand to benefit something from it.
