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.

[@jollynery]

@@SimplilearnOfficial can blockchain be used in education?

[@AndrewSmith00000007]

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?

[@werd2182]

I still can't figure out what "problems" this is actually solving (other than putting everyone further into slavery). So now you have to work for the money you're already spending transaction by transaction? Review a ledger and validate each transaction? Sounds more burdensome than anything.

I'm quite new into the Blockchain technology, and I have a question on the part where you say "public distributed ledger", where all Phil's friends have a copy of the ledger and know how much bitcoin Phil has left (1 bitcoin left at minute 2:56). In this case, does it mean people who have a common copy of your ledger will always know how much "money" (bitcoin for example) you have in your account? Apologies if it is a dumb question, kinda new here 😅

[@aadiluddin]

The ledger (blocks) are encrypted, so no one can see how much Phil has in his account.

[@Tonchbonoan]

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.
