Proof of work

[TimopheyKa 3900]

Friend, this is extremely useful information, the fact is that it seems to me that the cryptocurrency has very strong protection, because, for example, in order to break it, we clearly need a data stream with different hashes, and this is extremely difficult! Many people even ask whether a quantum computer can break bitcoin, or whether all this is extremely unrealistic? It seems to me that we got into such a system that we created, but we can't break and delete it, because experience and technology do not allow it! This is the whole mystery of the Bermuda triangle!

As we know and as I have talked about in my previous topic, Blockchain uses something called Hashes to make the chain of blocks and the method of adding new blocks more secure. But to tell the truth, using Hashes is not enough to prevent tempering.

 

 

Nowadays, computers are being very fast and they can calculate hundreds of these hashes per second.

 

Hackers can effectively temper with the block and recalculate all the hashes of the blocks to make the blockchain valid again like nothing happened.

So, to mitigate this problem, Blockchain had something called

 

Proof-of-work.

And what do we mean by Proof-of-work?

 

Proof-of-work is the mechanism that slows down the creation of new blocks

 

In the Blockchain of Bitcoin, it takes about 10 minutes to calculate the required proof-of-work and add a new block to the chain.

 

 

This mechanism makes it very hard for hackers to temper with the blocks. Because if someone tampered with one block, he/she needs to recalculate the proof-of-work for all the following blocks.

 

 

Although these methods of securing the chain of blocks, the Blockchain secure them selves also by being 

Distributed.

Instead of using a central entity to manage the chain, Blockchain use a peer-to-peer network and anyone is allowed to join.

 

Let's explain how this thing works.

 

Actually, when somebody wants to enter and join the network of blockchain, he/she will gets the full copy of the blockchain.

So that, the nodes (Members of the network) can use it to verify that every thing is still in order.

And when someone creates a new block, this block is sent to everyone on the peer-to-peer network.

 

Then each node verifies the new block to make sure that it has not been tampered with, and if everything checks out, each node adds this new block to his own blockchain.

 

So, Blocks that are tampered with, will be rejected by other nodes in the network.

 

Which means, to successfully tamper with a blockchain, you will need to tamper with all the blocks on the chain, redo the 

Proof-Of-Work

for each block and take control of more than 50% of the peer-to-peer network.

Only then, your tampered block will be accepted by everyone on the network which is almost impossible to be done.

 

 

What do you think after all that security methods?

@Omar98 yes my dear first of all thanks for sharing this piece of information with crypto Talk members this piece of information will be helpful for everyone are working here members. It was very long and and getting some time but I got some experience from your post and thanks for sharing this experience with us,  I will try to apply these all methods and advices and knowledge in my own working method. Miss you all the best my friend for future posting material for us. On the other hand if we see the security of Crypto talk is very amazing and hard. And it is very helpful for us because it is free from scammers and other fake persons. So thank you for sharing this information with us. 💞🥰

Hello, I have a question regarding the blocks that are created, does this have something to do with how long bitcoin takes to make a transfer?
Since sometimes it has been seen that a miner comes to accept the transfer, but I have also heard that it takes time to accept it because the fee is low, so you have to pay a higher rate.

I am very happy that these security measures are put in place to secure all of our earnings in the crypto world from hackers and scammers who are trying to steal them and I hope that more steps will be implemented to keep away the hackers.

@Omar98 great wxplanation my friend !

This would make it very easy for people who are not familiar with crypto technology to understand why the blockchain is super safe from being hacked.

Many people read about the PoW but they still dont get it because the get lost in the technical details of it. But this made sure to cover all kinds of audience

Am still not okay by the topic proof of work but with this little explanation I believed that some didn't understand how it work and also hackers is scammers do want to join the forum without following forum pop procedures so that they will cheat but with the cryptocurrency technology their will not have any way to do that thanks.

[Zohaibkhizer 466]

 Your success is the proov of your work. If you will work hard in your work then your success will prove that you have worked alot. 

[UsmanMehmood 374]

Positive likes is proof of your post that your work is very good and people are reading and understanding what you comment and trying to see from your perspective.So what you get likes is the proof that the work you are doing is right.

The thing that  got it by your comment is that you did not understand the PoW very well, did I get you well?

Anyway, I suggest you to read my previous topics which might help you in understanding the things I am talking about here. And if you need any help I am ready to answer as much as I know.

Good luck.

The truth is there is  a lot of effort to which  its really important , its important to work  with this kind of knowledge , its really important to find solution to what is the right thing to do right now we have different things that we are able to find out there we are always going to get this kind of information in this place its really a good thing to use this site to get this article learnt a lot from it 

[Jidson 252]

@Omar98 Thank you for sharing this useful post with everyone of us in order to have a safe account. You have really done a good and explanatory topic giving us a better understanding on Blockchain and how it can be prevented from being hacked. I believe we all learn from this topic greatly.

[Zaman222 415]

I am still learning everything related to cryptocurrency and this makes me not to have any knowledge on this topic because i don't have any knowledge on cryptocurrency Blockchain but I think i have picked something little even if not much with the level of my understanding on cryptocurrency.

You can't do without a hash in cryptocurrencies, or rather in the blockchain. Each block forms its own unique hash and it is written to the next block along with new transactions and miners again find the hash of this block and add it to the next one. This is done so that the history of the blockchain cannot be rewritten.

I agree with you, a lot of information about Blockchain can not be written due to the variety of information that the history of Blockchain has.

 

But the only thing that we can do is to learn and read as much as we can about blockchain in order to know the mechanism that it is working on so we can understand the things around us now a days.

[Shuvo Mia 576]

Oh man. You did a amazing job here. Your good is really good. Thanks for the post. You explain some good topics which is really cool. This will help for all of us. Hopefully admin, moderator will see this. And in next update in future they may think about this and include this.
