Hi each one, I recognize you all. I will jump at the chance to thank and properly professor @sapwood for this extraordinary example about Different Types Of Consensus Mechanisms Thanks again, I went through your post, read, and comprehended the ideas you gave. I will finish my task for this undertaking, for which I will be responding to number one, which requests as follows:
Answering Question 1:

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

Firstly i will like to expanciate a little more about proof of work( PoW) and proof of stake(Pos)

proof of work

• PoW agreement system requires a great deal of registering work to tackle the complex numerical riddle, and the diggers are entrusted to approve the exchange, record them on the public record, which likewise turns into a piece of the "chain of squares".
  At whatever point an exchange in the Blockchain network is started it will go into the unsubstantiated pool, then, at that point, the diggers are entrusted to tackle the cryptographic riddle to confirm and approve the exchange. The one that is approved is included the Block (alongside a timestamp and its past timestamp). Any subsequent endeavor to spend a similar sum will be nullified and pulled out from the organization.
  On the off chance that both the exchanges are taken all the while from the unverified pool, the one which got the primary affirmation is considered substantial.
  Further, the speed relies upon the Block delivering season of a specific organization. For Bitcoin it is 10 mins while for Litecoin is it 2.5 mins, both utilize the PoW system to arrive at an agreement.

proof of Stake?

proof of Stake(PoS) which is a framework that licenses clients or machines to work well in a conveyed setting, settles on who checks the following square, contingent upon the amount or measure of coins the singular holds, as opposed to excavators utilizing PCs to check exchanges as they do on account of the typical or standard Proof of Work, truth be told the PoS idea is incorporated, and the primary Cryptocurrency to do a total and careful PoS agreement model is Peercoin.
this model randomly chooses the winner based on the amount they have staked.

What is the difference between PoW and PoS?

source

• In brief summary
  In PoW, the probability of mining a square is chosen by the measure of PC work that is finished by an excavator, while in PoS, the probability of confirming or checking another square is chosen by how enormous the measure of a coin an individual has, and obviously in this last case, the amount of coins an individual has matters.

• Cryptographic riddle is about excavators utilizing their processing ability to unpredictably deliver numbers at a fast speed, and on the off chance that they produce the triumphant number, they win a lottery, though in PoS, the validator doesn't get a square prize rather he gets network expense as his award, and for this situation, a validator is somebody that is accused of the undertaking of checking or affirming blockchain exchanges regarding if they're lawful and exact.

• Evidence of Stake, there is no battle since block maker is chosen by a calculation that is established on client token or prize.

• In Proof of Work, for programmers to have the option to connection or join deceitful square, it's necessary that they have 51% of calculation force, and this calculation power alludes to how quick a machine can play out an activity, though in Proof of Stake, it would necessitate that programmers have 51% of all advanced cash on network, which is for all intents and purposes unrealistic.

  The Advantages Of Proof Of Work (PoW)

• Truth be told, one of the fundamental benefits of the PoW is that this agreement system offers block rewards and different advantages to it's diggers, such advantages as a specific level of the mining expenses or charges, for mining on this instrument.

• This convention additionally delivers a decentralized organization which is the Paramount or boss premise of Cryptocurrency exercises.

• The Proof of Work(PoW) keeps the blockchain in an exceptionally convoluted or troublesome manner while simultaneously being incredibly troublesome and exorbitant to assault.

The Disadvantages Of PoW

• The Proof of Work brings about high energy utilization along these lines significantly raising the expense and the impact on the climate and this could similarly be relentless and hard for the client.

• The Proof of Work brings about delayed reliance on mining exercises even while as of late delivered computerized monetary standards keep on partaking in the crypto market

The Advantages Of The Proof of Stake (PoS) Concept

• The Proof of Stake needn't bother with computation force and they're more energy effective. Likewise, the Proof of Stake gives incredible advantages and prizes to diggers who utilize their cryptographic forms of money.

• The Proof of Stake similarly can be supposed to be without hazard with regards to arrangement of safety for excavators in the future to empower them get remuneration in case of any fake exercises on the web, for example, digital assaults or digital wrongdoing.

Detriments Of Proof of Stake(PoS)

• Verification of Stake raise the establishment for a decentralized organization, attempting to seriously harm the fundamental establishment for the digital money framework.

• The PoS is concentrated and less secure, consequently could be helpless against bad quality assaults in this way carrying harm to client speculations.

  Which one is better in scaling capacity?

• From my exploration discoveries, I would infer that the confirmation of Stake is preferable in scaling limit over the PoW, given the way that the Proof of Work (PoW) limits scaling limit.
  

  Examples

  
  Peercoin, Nxt, Blackcoin, Etherum, ShadowCoin etc use proof of stake.
  

  Peercoin

  
  
  source

• In Peercoin coin owners are the ones who wield influence over the network, produce new blocks, and secure the chain. Voting is carried out the same way Peercoin is secured, through a process called proof-of-stake minting. Every minted block rewards stakeholders with new PPC and a vote.

• This is one more impressive illustration of the Proof of Stake(PoS) framework. Their squares are created each 1 moment on normal by accounts that are opened by PCs that help the organization and imitated by a producing interaction.
  

  Etherum

• Ethereum can be said to be one of the major cryptocurrencies that is solidly founded on the Proof of Stake concept, for that affort has always been directed towards the development of Ethereum especially since the inception of their phase 2 upgrade. For example, Ethereum users are required to invest 32 Eths to be able to validate transactions, since they are irregularly selected, and also verify and manage blocks that are under their care.
