What is the difference between PoS and PoW?

Markus Jakobsson and Ari Juels coined the term "proof of work" in a document released in 1999. It has something to do with bitcoin. Proof of Work (PoW) is a technique for forming secure digital transactions without the need to trust a third party. This work expands on previously solved puzzles. PoW could be used to validate current and previous transactions. Mining is a term used to describe the process of solving a challenge that results in rewards for the person who solves it. To put it another way, this is frequently an algorithm meant to verify transactions and add new blocks to the blockchain.

Important marks about PoW:

-        Because work is extremely difficult, PoW minimizes the risk of a 51 percent attack.

-        No single miner will be able to dominate the Bitcoin network Based on the Hashcash Proof-of-Work technology.

-        Before proposing a new block, the miners must demonstrate that they have completed some work.

-        At the same time, each answer is simple to validate by the community. This makes it simple to verify the legitimacy of all transactions.

-        PoW also imposes a limit on the number of new data blocks that can be created. Miners can only create a Bitcoin (BTC) block every 10 minutes, for example.

-        It does not use any third-party transactors. This creates a network that is "trustless" and transparent.

-        Monopoly's value might rise with time.

Instead of miners breaking cryptographic riddles with computer power to verify transactions like they do with traditional Proof-of-Work, Proof-of-Stake (PoS) is a consensus mechanism that selects who validates the next block based on how many coins you own.

Important marks about PoS:

-        The size of a person's stake determines the likelihood of validating a fresh block.

-        The validator does not receive a block reward; instead, they are compensated with network fees.

-        Peercoin was the first cryptocurrency to use the PoS consensus model in its entirety.

-        Monopoly and Power Consumption are dealt with.

In fight against global warmings, companies are rather deciding for PoS type of cryptocurrencies, even though that bitcoin is PoW. PoS are much more cost and energy efficient than PoW, however they are less proven. Initial investment in PoW is to buy a hardware, while in PoS it is to buy stake and build reputation.
