@217officeoffice9 2 года назад

Great. I am not the only one assuming this. Clear and well explained in short time [.~.movements.~.?].

@gowtham4JSP 5 лет назад

Thank you sir.. Waiting for more videos about BlockChain !!

@ushasaibaba8793 5 лет назад

sir i have one doubt suppose the last block will be hacked by some one hackers. bcz all datas are in last block there then the data must be losted then how it possible?

@prembhargav1859 2 года назад

Really you are doing spoon feed the explanation is clyster clear great job

@Theananomousvj 5 лет назад

@junaidahmed9617 5 лет назад

What if i do a mistake in a block and later after a year i find out that mistake and i want to rectify it , the whole chain for the year will change ?? Or

@dn9416 5 лет назад

Transactions once added to blockchain cannot be changed for what ever reason.. If whole network is corrupted due one fault, when we have a beautiful feature called fork...

@dazelmann6589 4 года назад

You will work upon different branch after rectifying the correct change and will then fork the latter changes you did

@harshanadendla5873 5 лет назад

Sir did not understand "need 50% of validation in blockchain network".....plz explain.

@79ompatil26 4 года назад

It's like a doubly linked list except it's filled with hash values and other complex stufff

@carl5192 3 года назад

I always describe it as that too.

@diteshpoojaritechgeek 5 лет назад

So if a particular block gets changed, for that new block will be created with new hash and updated data. And if so what happens to the old block? will it still be there?

@Anonymous0224. 5 лет назад

PLZZ ANSWER SIR,......How to evaluate on in which block the change has made if in case of hacking how to analysie the block on which the change has been made as every hash is connected to new chain

What happens if I change b5 then it won't have any blocks connected to it in forward direction

@Riskw-mk1lo 3 месяца назад

public ledger. all has one type of ledger but you'll have different, so the operation would be invalid

@debangshubanerjee1311 Год назад

just going by the above explanation, the last block can be manipulated easily r8? coz theres no more blocks containing the linkage, so lets say the last block is addedat time x. the next block will only be added in x+10 min, so in this 10 min the last block can be manipulated?

@saumyap07 Год назад

NICE EXPLANATION

" Block chain can solve issues based on data , not all the problems "

@shivkrishnajaiswal8394 3 года назад

can the timestamp not be modified?? Should there not be a server from which timestamp must be validated. If I have installed a blockchain system in my system then whenever i modify/add/update a new block, how is timestamp calculated?

@babak.basharirad 2 года назад

Good explanation, but wouldn't be much clearer, if you speak slower? Even youtube cannot understand and make the caption! POW is not clearly explained.

@ankittripathy7065 3 года назад

Thank you so much...!

@alt-f4gaming222 Год назад

as i am a beginner , there is a question in my mind why are we using many blocks to store the data and connecting them with hash, why cant we just take on block only ...

@alt-f4gaming222 Год назад

one block**

@vijayanandmehta6379 5 лет назад

Nice and simple explanation provided... thank you so much Naveen sir 😊

@muzmmilpathan7781 5 лет назад

Sir it looks like a linked list

@victoryfile 4 года назад

Think of the blocks as the elements of a linked list and the communication protocol between two blockchain nodes as the "link" and you'd be right. It LOOKS like Linkedlist.

@virajshah6362 3 года назад

@abdulazizalharbi6228 2 года назад

what about changing the last block? there is no block a head of it that will causes a problem when the hash of the last block changes due to changing the data, how is this problem handled ?

@debangshubanerjee1311 Год назад

my question too

@soumyadipchowdhury297 5 лет назад

@amanjain256 2 года назад

If we have 5 blocks, we have made sure that previous blocks cannot change data without other blocks noticing it. But what if, the 5th block which is the latest added block, changes data present in it?

@midwestmetro6361 2 года назад

The data cannot be changed too, because it’ll need 50% of the majority of the blockchain network to approve of it. And a super computer. Same reason 😁

@midwestmetro6361 2 года назад

But if the data changes, the hash definitely changes

@noobie6784 2 года назад

Intro song was nice. Can i get the name

@rishabhchaudhary6207 3 года назад

Sir it is confirm that we can change data in blockchain

@awsomekaran4836 3 года назад

There is no way you can change data as it creates new key and it makes invalid to other blocks if u edit it . So even for changes it creates new block with new key nd changes are done thru voting which is later in series named consensus.

@karysutariya1651 3 года назад

don't you think will raise issue of black money. because, no one controls this blockchain.

@amaljose116 2 года назад

A nooby question : Does each block represent each coin in the crypto?

@coldfusiontv 2 года назад

Each Block Is Like A Receipt, Where You Can See The Transaction Details...The only thing is, you cannot manipulate the data around and within any block because it's a Blockchain!
