Translation (convert and preserve HTML structure, not in code blocks): [English] Why can we say PoS is superior to PoW?

I know about Bitcoin and cryptocurrencies, butPoSandPoW— I’ve heard of them, but I don’t really know what they are! If that’s you, use this opportunity to learn the key points at least.

Could this influence your future investment decisions?

What are PoS and PoW?

They aretypes of consensus algorithms— a way to reach agreement. One wonders which consensus algorithm would be most suitable for the world ahead...

PoWisthe high computational power of computers,PoSisthe amount of coins ownedthat determines mining rewards. Simply put, PoW is used by Bitcoin, and Ethereum, which currently uses PoW, will eventually transition to PoS (a proprietary PoS often referred to as Casper).

So, here are some responses from a recent survey.

Which do you think will improve the world?

This contradicted the expectation that PoW would dominate. Perhaps because many of my followers are Nem fans (NEMber / NEM enthusiast). (NEM uses a PoI-like PoS, details at the end)

Thus, I translated an article that compared PoW and PoS and claimed “PoS is superior!” Which side are you on?

Why can PoS be considered superior to PoW?

If you have engaged with cryptocurrency communities for a while, you’ve probably heard of PoS (Proof-of-Stake).

It is the mining concept used by several traded coins,where you distribute mining rewards in proportion to the amount of coins you own. In other words, regardless of computer processing power, someone who holds 1,000 coins can mine more than someone who holds 10 coins.

Some welcome this concept, while others remain skeptical and avoid it. However, considering coins like Ethereum (ETH) beginning to adopt PoS, it’s clear there are several advantages to PoS.

What exactly are those advantages?
From the information I gathered, PoS has several fundamental benefits.
