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
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...
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?
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
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?
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?
Great analysis, thank you! Could you help me with something unrelated: I have a SafePal wallet with USDT, and I have the seed phrase. (air carpet target dish off jeans toilet sweet piano spoil fruit essay). How can I transfer them to Binance?
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.
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?
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 ...
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 ?
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.
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?
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.
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!
Thank you for the great explanation! Just subscribed! Keep it coming man
Great. I am not the only one assuming this. Clear and well explained in short time [.~.movements.~.?].
Thank you sir..
Waiting for more videos about BlockChain !!
It's like a doubly linked list except it's filled with hash values and other complex stufff
I always describe it as that too.
Navin reddy , Is it still worthy learning blockchain?Are there any implementation in real world?

You will work upon different branch after rectifying the correct change and will then fork the latter changes you did
Awesome. keep it up my brother.
All the videos are awesome.. But Please make some more videos regarding to block chain..
Sir when will you start real programming of BlockChain?
@@Telusko
you finished the series without
you should keep promises
lol
Really you are doing spoon feed the explanation is clyster clear great job
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?
Sir u will get 1m subscription very quickly
Sir did not understand "need 50% of validation in blockchain network".....plz explain.

GREAT VIDEO
THANKS
Nice Sir
awesome videos sir.. very clear and simple
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?

Really great explanation ..Thank you so much fr ur videos
Sir it looks like a linked list

Nice and simple explanation provided... thank you so much Naveen sir 😊
Thnx sir
1st view,comment and like.....
Sir how will block 2 know if the data is changed in block 3 ? Only H3 onwards the hashes will change right?
Make one video on Data science🙏🙏
mashallah best explanation
What happens if I change b5 then it won't have any blocks connected to it in forward direction
public ledger. all has one type of ledger but you'll have different, so the operation would be invalid
Please make a tutorial on "Java Reflection API" please.
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?
Thank you Sir.
Thank you so much...!
NICE EXPLANATION
sir give me idea for phpmini project in last year of bcs project is frsh or no exist in real life but it to be needed in real life
Hey!
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 ...
one block**
Really nice explanation sir..Thank you so much.. excited for the next session..
" Block chain can solve issues based on data , not all the problems "
Big big thanks for your videos .The videos are crisp and clear.
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 ?
my question too
Good explanation, but wouldn't be much clearer, if you speak slower?

Sir can i know the constraints for creating a block in ethereum?
iam enjoying it
finally sir
Intro song was nice. Can i get the name
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?
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 😁
But if the data changes, the hash definitely changes
hi naveen if u upload a series of videos daily will b helpful coz its difficult to follow aftr long gap on block chain
I don't think you know how to use air quotes 😅 anyway great video man 😇
Sir it is confirm that we can change data in blockchain
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.
don't you think will raise issue of black money. because, no one controls this blockchain.
A nooby question : Does each block represent each coin in the crypto?
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!
