Hello Steeminars,
"Assalamu Alaikum" I hope everyone is well, Alhamdulillah, I am also well in your prayers by the infinite grace of Allah. Welcome to the Steemit Crypto Academy and I would like to thank professor @sapwood for informing me about such an instructive subject through you, this post is very important to me, Because I have learned a lot of new things through this post.

What is the difference between PoW and PoS? Advantages and Disadvantages? Which one is better in scaling capacity? Examples

What is the difference between PoW and PoS? Advantages and Disadvantages?

Proof of Work:
PoW miners on blockchain networks verify and sort blogs using their computing power by solving complex math puzzles. And this verification proves their efforts towards the development of specific networks through sorting. Basically, it goes to a deal that stops any malicious use of computing power like sending spam emails and others. A consensus mechanism used in blockchain technology. It is a hacker-free network so BTC is currently using it in a consensual process.

Proof of stake:
On the other hand, has reached a consensus by stacking coins already on a particular network without solving mathematical puzzles with computing power. In other words, it is a contract that validates block transactions based on the number of coins you hold or hold. This means that the more money you have as a murderer, the more power you will have. It was created as an alternative to the PoW and is the consensus algorithm used by networks like Steem, NEO NXT.

The difference between Proof of Work and Proof of Stake

SL No	Proof of Work	Proof of Stake
1	PoW uses a greater amount of computing power throughout the mining process.	When verifying the POS of a new block, users rely on the amount of coins they hold.
2	The probability of excavating the mine block is measured by the amount of computational work done at the moment.	The probability of this being a new block is measured by the amount of coins the person has.
3	When it comes to the use of electrical energy, PoW consumes more electricity than PoS.	PoS is a mining process when it comes to the use of electrical energy.
4	PoW rewards the first miner who is able to solve the cryptography puzzle of all or every block.	Although the partner receives a network fee as a reward for proof of legitimacy.
5	Miners at PoW use designated hardware to control processing power.	Anyone can be involved in POS if they have an internet connection.
6	Proof of Work investment is basically in the case of buying hardware	Partners invest in buying proof shares and building a reputation.
7	The estimated amount of electricity used per day is 150 thousand dollars and more.	PoS systems use less electricity at a lower cost which makes energy more efficient than Proof of Work.

Advantage of PoW:

• PoW is seen as a decentralized system, as its results are often in a decentralized form.
• It is very difficult for hackers to take control of the network because security is the main advantage of POS over POWs.
• Attempts to participate from the transaction fee and block rewards as a work reward.
• This makes it difficult for attackers as it is very expensive.
• In order to solve the mathematical puzzle for legitimacy, the network gradually demonstrates fairness in the advanced competition among miners.

Disadvantaged of PoW:

• POWs consume a lot of energy which affects the environment more than the evidence.
• This is limited to the people who are in possession of the mining setup which makes it very difficult.
• Its security should be looked at as it does not have a large network to guarantee adequate security.
• It is very less scalable and also It requires a lot of experience and skills.

Advantage of PoS:

• This POS system consumes less energy so energy efficiency is higher.
• Proof of partnership is derived in proportion to the holding or holding currency of the mining power.
• In this POS system, people with little network experience or skills can easily participate in the stacking process.
• Evidence from POS systems is seen as more secure than POWs.

Disadvantaged of PoS:

• The POS system is considered less secure than the PoW system.
• It can give hackers the opportunity to attack the dual cost by verifying multiple identities to prove partnership.
• Stacking by pressing the system is thought to have an exclusive existence because those who have enough money to buy coins have more reputation on the network.
• The Proof of Stake system award is given unreasonably based on a fun amount that only helps the rich get richer.

Which one is better in scaling capacity? Examples

The Proof of stake is more effective in light of this fact as current holders risk their coins to deal with transactions against their mining. The proof of stake partnership Scalability is stable. This is because legitimate actors are randomly selected for each round where they are agreed only if they become part of the blockchain.

Rather than proof of work, where the winner gets a prize and the other person doesn’t get it, each part is essentially a prize to increase PoS investment. In the case of scaling, the evidence of the partners is better because hackers face most of the problems of their attack. The Proof of Stack has proven to be better for the environment than the Proof of Work, which makes the mine scalable.

So if there is not enough capacity to deal with the growing trade volume, the reward is extended so that more people have to strengthen their coins. But many people are at risk when the floodwaters recede. It considers productive scaling as the demand for currency development until there is no oversupply and no reward. Where the more successful the coin is in proof of work the more complicated the puzzle becomes thus making it harder to solve which in turn reduces its ability to be measurable. This statement proves that PoS has more measurable power than PoW. Examples of currencies used in PoW are Etherium, BTC.
Examples of currencies using the same PoS, on the other hand, are NEO, NXT Steem and Blackcoin.

In conclusion, considering the above content, it is clear that the scalability of Bitcoin, the proof of stake system, and its effects provide more solutions. The Proof of Work system on the environment is proving, in fact, that it is really helping to save energy for future generations.
Thanks for reading my beginner`s homework task.
