**Great day steemians,** I warmly welcome my dears Today, I will present my Homework post for Task 6. ![Grey and Yellow Modern Corporate Business YouTube Thumbnail (2).jpg](https://cdn.steemitimages.com/DQmWWaVCdBa8MjMiEFh7xmw4RZXyXe6hegR3MSy68jtKCYF/Grey%20and%20Yellow%20Modern%20Corporate%20Business%20YouTube%20Thumbnail%20(2).jpg) image designed by [Canva]() ![crypto academy my logo.jpg](https://cdn.steemitimages.com/DQmYkK2taHow1wr81YHSCRnbvCVYn3od97dZBMj2Tx1Hc76/crypto%20academy%20my%20logo.jpg) --- **Homework Task** --- >(1) What is the difference between PoW & PoS? Advantages & Disadvantages? Which one is better in scaling Capacity? Examples? --- ![crypto academy my logo.jpg](https://cdn.steemitimages.com/DQmYkK2taHow1wr81YHSCRnbvCVYn3od97dZBMj2Tx1Hc76/crypto%20academy%20my%20logo.jpg) --- (1) What is the difference between PoW & PoS -- First we identify the PoW and PoS separately. Then,I like to start and discuss about the consensus mechanism. --- CONSENSUS MECHANISM ![Consensus_Mechanisms.jpg](https://cdn.steemitimages.com/DQmNo3mfVwPWYGYnpxMhpJ125Et8Z5DUU9c5Rf7MwmAB1iL/Consensus_Mechanisms.jpg) [source](https://releaseyourdigitaltalent.com/wp-content/uploads/2019/11/Consensus_Mechanisms.jpg) --- A crucial issue in appropriated registering and multi-specialist frameworks is to accomplish in general framework unwavering quality within the sight of various damaged processes. This frequently requires organizing cycles to arrive at agreement, or settle on certain information esteem that is required during calculation. Model utilizations of agreement incorporate settling on what exchanges to focus on a data set in which request, state machine replication, and atomic broadcasts. Certifiable applications frequently requiring consensus incorporate distributed cloud computing, clock synchronization, PageRank, assessment development, shrewd power matrices, state assessment, control of UAVs (and different robots/specialists overall), load adjusting, blockchain, and others. --- PROOF OF WORK (PoW) --- The PoW is an agreement system by which an understanding is being reached between servers/hubs in the decentralized network on the handling and check of exchanges (i.e an arrangement should be made before a specific can be named 'VALID'). This typically requires a great deal of work and energy on the minors part as they do a ton of arithmetic and calculations. The miners are entrusted to settle a progression of science puzzle to have the option to make a square which will be added to the chain. This is the place where the work lies for the minors as it's anything but a simple assignment however when the diggers can tackle the riddle issue, they are normally compensated. A genuine illustration of a crypto project that has embraced this PoW agreement instrument is the Bitcoin and Etherum. --- Confirmation OF STAKE (PoS) --- PoS (Proof of Stake) This is one more consensus mechanism that has been embraced by ongoing crypto projects. Dissimilar to the PoW, the PoS calculation doesn't need settling numerical riddles neither does it require computational works to approve its exchanges, this assists with saving energy and registering power assets as almost no work is should have been finished. To the extent the proof of stake consensus mechanism is concerned, the convention is more centered around how much stake possessed by members. Generally, I am attempting to say that members who will approve transactions are typically chosen arbitrarily as per how much stake they own in the organization. This perpetually implies that, the higher the stake of a member, the better the shot at him/her becoming chosen to turn into a validator. Instances of crypto project that takes on this framework is Dash, Cardano, Solana and so forth --- https://i.ytimg.com/vi/hzT44jf94Nk/maxresdefault.jpg [source](https://i.ytimg.com/vi/hzT44jf94Nk/maxresdefault.jpg) --- Presently, we should compare the difference among PoW and PoS. From the conversation, we can just separate PoS from PoW base on the accompanying focuses underneath : PoW | PoS --------- | ---------- PoW is a decentralized framework | PoS is more incorporated It requires hight cost to work or run | It is moderately less expensive to work It includes mining |Doesn't include mining Includes computational work by the miner |Doesn't include computational work Requires more energy | Requires less work and energy (i.e it is energy productive) It includes settling of numerical riddles to approve exchanges |It doesn't includes settling of any type of riddles as approval of not set in stone dependent on the stake of members There are compensations for Miners| There are no compensations for validators The method involved with adding another square is known as Mining| The most common way of adding another square is known as Minting The PoW is safer| The PoS is less gotten --- ![crypto academy my logo.jpg](https://cdn.steemitimages.com/DQmYkK2taHow1wr81YHSCRnbvCVYn3od97dZBMj2Tx1Hc76/crypto%20academy%20my%20logo.jpg) --- ADVANTAGES AND DISADVANTAGES --- Both PoW and PoS have their upsides and downsides which I will explain them underneath ADVANTAGES OF PoS - One novel benefit of PoS over the PoW is that the PoS doesn't need any computational work neither does it include addressing any numerical capacity, consequently it is energy proficient. - The PoS additionally saves cost since it doesn't include the utilization of various complex machines and PC equipment that are expensive - The PoS is all the more quicker when handling transactions as it doesn't depend on a ton computational work before exchanges can be approved subsequently, it is more adaptable. DISADVANTAGES OF PoS - Intrigued members or validators should have a stake of the Cryptocurrency project before they can be chosen, subsequently it isn't promptly open. - The PoS is more helpless against 51% assault, and moreso, it's a fresher framework contrasted with the PoW, thus it is less gotten. - The award for marking in PoS is very little contrasted with what is realistic in PoW where miners are compensated well. ADVANTAGES OF PoW - The PoW is a more strong framework contrasted with the PoS, thus this instrument doesn't energize or allow any type of misuse, compromise or abuse by members. - It relies upon series of computational works which makes the framework more got in light of the fact that it will be undeniably challenging for any programmer or hacker to think twice about blockchain, for this situation the expense of altering it is typically higher than the addition for sure the programmer will benefit, subsequently the pressure isn't dependably worth the effort. - There are great awards for miners who are liable for settling numerical riddles and computational works. DISADVANTAGES OF PoW - It is energy wasteful as it includes a great deal of work, the miners are consistently caught up with attempting to perform computational works, addressing numerical riddle, making and adding of new squares. - The PoW is an exorbitant endeavor as it includes the very complex procurement modern PC equipment and machines. - Exchanges on the PoW network isn't actually that quick of PoS since it includes a great deal of computational works and numerical capacities which eases back exchanges. --- ![crypto academy my logo.jpg](https://cdn.steemitimages.com/DQmYkK2taHow1wr81YHSCRnbvCVYn3od97dZBMj2Tx1Hc76/crypto%20academy%20my%20logo.jpg) --- Which one is better in scaling Capacity? Examples? With regards to adaptability, the PoS has shown to be more versatile contrasted with the PoW. The explanation isn't fantastical, the PoW involves the utilization of strong PC equipment which are exorbitant to secure and this PCs burn-through a ton of energy and requires a significant degree of support. The diggers are associated with settling such countless numerical riddles which makes the framework slow, this are not realistic in the Proof of Stake as it is energy proficient, less exorbitant and has no adaptability limits. Instances of PoS and PoW tokens should be visible in the screen shots underneath --- ![coin market cap.jpg](https://cdn.steemitimages.com/DQmfFo9F9Zf9spr68P2vEfLWMmcgZc461qRJpNF5WQ54GPM/coin%20market%20cap.jpg) [source](https://coinmarketcap.com/view/pow/) --- ![coin market cap2.jpg](https://cdn.steemitimages.com/DQmNWGUV8kX3PcJ29G9zcx68tGYpahjsTzpHP58MQbc2rir/coin%20market%20cap2.jpg) [source](https://coinmarketcap.com/view/pos/) --- ![crypto academy my logo.jpg](https://cdn.steemitimages.com/DQmYkK2taHow1wr81YHSCRnbvCVYn3od97dZBMj2Tx1Hc76/crypto%20academy%20my%20logo.jpg) --- CONCLUSION --- It's great to realize that the world is developing and the digital money ecosystem system isn't abandoned. Finding out with regards to the diverse agreement system has been fascinating as it has been approved my accept and confide about blockchain innovation. Extraordinary because of my superb teacher @sapwood for an incredible Job on this course. I desire to continue to gain from you. thank you ! ![star mark.png](https://cdn.steemitimages.com/DQmS8U7pyAw9ut16Ycqv8rcnH4mxUvzheWs1P2oJSpbhKjx/star%20mark.png)
