Hello, dear steem friends of this great community of learning. I am really very happy to become a part of this community by completing fixed homework tasks for beginners. Today I am writing the sixth homework for professor @sapwood which is related to Different types of Consensus Mechanisms. I knew something about this and so I choose it first.

(1) What is the difference between PoW & PoS? Advantages & Disadvantages? Which one is better in scaling Capacity? Examples?

What is the difference between PoW & PoS?

Proof of Work (PoW)

Proof of Work (PoW), used as a technology by many blockchains, first appeared in our lives in 2008 with BTC. As the name suggests, evidence is being created. Because the blockchain system can be affected if the transaction verification function in the system is affected. This problem is solved with a family labor certificate.

All transactions made to the blockchain are designed to prevent trading. It is very difficult to solve the game in the local area and the evidence is presented. After the verification process, a timestamp is added and a block is entered. If the transaction is made at the same price and in two equal amounts, one of the transactions will be disconnected from the network. Here, if the verification process is performed for the same operation at the same time, the initial verification operation is valid.

The owner of the mine is less likely to create the right block and be rewarded, as total speed and resources are key components that allow the researcher to deal with the previous crypto dilemma and look at the next block. The biggest problem mine owners have faced for many years.

Proof of Stake(PoS)

Proof of Stake (PoS) is the authentication method used by blockchain networks. PoS stands for User Successful Cryptocurrency Transaction. This is a great alternative to cryptocurrency mining. Peercoin was launched in 2012 and is the first cryptocurrency to use POS.

In POS, users invest in specific nodes by depositing money. The node competes with the other nodes to secure the transaction. This will only work if inflation is detected in the POS.

PoS has a higher energy efficiency compared to PoW. This is because mining does not require powerful computer equipment. The user must block some tokens, and the partner’s token is returned for the transaction fee.

Differences between PoW and PoS

Proof of Work(PoW)	Proof of Stake (PoS)
The token and the network on the blockchain network control the transaction and reward the node as proof of minor work.	In the POS algorithm, miners cannot exploit the associated blockchain tokens. Instead, I am using a blockchain chip.
POW algorithms increase signal delivery on the blockchain.	The POS algorithm cannot add blockchain stains instead of displaying chips in the pool. This is very useful because supply and demand need to be balanced.
A roof consumes a lot of electricity. This large amount of electricity is very dangerous for our habitat.	Proof of Stake requires less power than proof of work because it is symbolic, not symbolic.
The reason for the POS signal extraction was the complete hardware-based POW. As we all know, mining uses hardware.	Proof of Stake depends on the amount of inventory produced by the inventory auditor. This is one way to reduce your hardware requirements.
The POW algorithm is slightly lower than POS.	In terms of efficiency, inventory auditing is more efficient than proof of performance.
POW is very economical due to hardware requirements. Hardware consumes a lot of energy.	Hardware and electricity bills are cheaper in PoS because it does not carry the entire network.

Advantages & Disadvantages?

Advantages & Disadvantages of PoW

---

Advantages of PoW	Disadvantages of PoW
PoW's miners receive the award after successful certification.	PoW Mining requires more efficient and cost-effective computing equipment.
It solves the most difficult types of complex puzzles and creates new blocks that are added to the pool.	It uses a lot of energy which is also valuable for minerals.
If users have a higher hash rate, they can create new blogs faster.	It is a system in which rich miners are more rewarding than less powerful miners.
Due to the decentralization, it regulates activities carried out using cryptocurrencies.	PoW requires a large number of transaction fees. It is a gas fee that is sometimes really high.
PoW is extremely safe due to the complexity that makes it very difficult to hurt the ears.	Completion of transactions is very slow and time-consuming due to slow block production.

Advantages & Disadvantages of PoS

---

Advantages of PoS	Disadvantages of PoS
The main advantage of PoS is low computing power consumption.	It is not possible to sell and generate PoS coins together.
The PoS transaction process is very fast.	PoS has a liquidity limit.
This gives mining power as a percentage of the coins that belong to the miners who have more, they have more options.	If you have a limited amount of chips, it will be more difficult to get into it compared to larger companies.
The value of a coin or token in PoS is more volatile than in PoW.	Users need to be wealthy if they want to use PoS. Because big investment means higher income.
In the case of PoS, the reward is given to the miners after successful certification.	Implementing a multifunctional PoS is considered a major drawback for security reasons.

Which one is better in scaling Capacity?

---

Basically, scaling is the operational capability that requires a series of blocks. scaling supports the block if the number works, so there will be less time to replace the tokens.

In my opinion, Proof of Stake performs better because it reduces the risk of mergers. The second reason I like to test bets is the speed of the deal because it depends a lot. so I think POS has better performance.

Examples?

BNB:

The local currency for exchange in Binance is called BNB. This BNB is another currency to use the PoS consensus mechanism. There are various ways to stake BNB using PoS by using Trust Wallet, BNB Vault. The current price of BNB is now $546.05.
