Hi, I have a test on business disruptive technology tomorrow and I would like to know about P2P network in an easy way and how to illustrate or draw a diagram for an example for blockchain.
Hi Sara, you can refer to our Blockchain 101 video where we have used an example and explained the P2P network in a simple way: kzhead.info/sun/iqdwaZiBroGrf2g/bejne.html.
Vary interesting. I was talking to one of my freinds who is up alot on the tech of the future. I was asking him about Bitcoins and that's when he also mention Blockchain but he had to get back to work so he did not have time to explain. Your video cover it vary well. Excellent video!

The answer for the last quiz you gave is option D - Hash encryption . Because whatever input item we have in whatever length , it will be as the same output item in a fixed length . So there is possibities of alteration .

Blockchain is changing every industry. Be the first mover and kick-start you career with our latest Blockchain Career Guide. Comment below for your copy. Hi everyone, exactly two weeks ago, we conducted a quiz contest in our Blockchain video. The answer to the quiz is given below: Option: A (Public Ledger) The concept of public distributed ledger ensures that everyone on the blockchain network has a copy of the ledger. Thus, no single person can make changes in the ledger as everyone else will flag this as invalid. Hash Encryption is not the right answer as this is used to maintain users' anonymity and verify their transactions' authenticity. We are pleased to announce the 3 lucky winners who got the right answer for our quiz: 1. Dinesh 2. Noel Philip 3. Vaishnavi Congratulations to all the winners! They've won an Amazon voucher worth INR 500.
So someone can alter the data, it would just be pointless? Correct me if I am wrong but this does not strictly answer what prevents alteration - if your answer relies on people flagging the now altered data....
@@Bamir96 In a way, yes, it depends on the people on the network. But as of now, the concern of the data being altered isn't one we need to worry about since it's never been done. More importantly, the process of altering the data within a block is one that requires a lot of processing power, and by the time this hypothetical process is fulfilled, a new block would have been added to the blockchain. This would render the whole alteration pointless.
@@SimplilearnOfficial Furthermore, if by any chance one of the participants successfully alters the Public Ledger, then surely the majority of the participants (51%) will loose confident in the network and the investment value will sharply decline.
You are right. Thanks for your valuable input!
Hello, I'd like to know what to write on the address 1 and 2 and what kind of postal code it shld be wen setting up Blockchain?

Perfect for a quick understanding of the concept before deep-diving into it. I was wondering in relation to the Walmart example if blockchain also describes the system of tracking damage when engaging in carsharing. Hereto, when you take pictures and note potential damage to the car before and after use, for the company to track when the damage to the car has occurred?
Thanks for watching our video and sharing your thoughts. Do subscribe to our channel and stay tuned for more. Cheers!
The answer to the question is A. Also, for an example, using the blockchain by mentioning the quality of a particular goods or service throughout the supply chain would help us immediately identify the origin of defect. As each part of the supply chain would have the knowledge of the quality of that particular goods or service at each stage.
Hi, you've got the correct answer! Option A! The concept of public distributed ledger ensures that everyone on the blockchain network has a copy of the ledger. Thus, no single person can make changes in the ledger as everyone else will flag this as invalid. However, the competition period is now over. Thanks for participating and watching!
@@SimplilearnOfficial can blockchain be used in education?
I don't understand how that would work in real world unless each step in the supply chain does quality check which sounds like a lot of overhead. Besides, if product is found to be damaged in one of those steps while performing quality check, what's the point of letting it shipped all the way to the store let alone put it on the store shelf?
Wow, this is such an eyeopener, where the world is heading to, i am really happy i came across your video, your explanation are soooo beginners and very understandable. Thank you
Glad it was helpful!

Hi! Thanks for the video. I think the answer isn't public distributed ledger, but instead it is proof of work or proof of stake depending on the type of coin/network being used. In a public distributed ledger, the data can actually be altered because of the rule of majority. So if a majority of the group of users decide to be fraudulent and make a even longer list of blocks in the blockchain, then the network will consider that to be correct as it deems that whetever is longer is correct. In this scenario, they can make changes to the data in the blocks. If the question was "what is the concept of blockchain that ensures data cannot be altered by any SINGLE user within the network, then the answer could be public distributed ledger since 1 persons work will not outwork the majority of the people who are validating blocks using proof of work/stake. Id say the closest answer is proof of work/stake as it is a way of validating blocks in the block chain. Once a block is validated, then it becomes permanent. Would you agree? Thanks!

@@SimplilearnOfficial hi thanks for the response! Yes, no SINGLE person can make a difference. But the question stated that users cannot make a difference which is wrong cause they actually can if they gain majority of the users. If you put the words no single user can, then that would be correct. But that is not the case in the question so the closest answer is proof of work.
This is the best explanation of what is blockchain, thank you
Glad it was helpful!
