  Blockchain !! The most secure technology that makes it very difficult to change or hack any data. This is the most secure technology for data transmission in the world. Today we will describe about blockchain.

• Blockchain in transactions
• How blockchain technology works?
• Why is blockchain technology becoming very popular?
• Why blockchain is unhackable?

we are explaining these below...

What is blockchain? :

Blockchain is a continuously growing recording of blocks and data that makes it troublesome or difficult to change, hack, or cheat the framework. It is linked and secured using cryptography. A blockchain is basically a computerized record of transactions that are copied and circulated across the whole organization of PC frameworks on the blockchain. As it's a decentralized system that is managed by multiple computers or participants. There is no single author to control it !! That's very amazing !!

How blockchain technology works? :

Blockchain is basically an advanced record of transactions that are duplicated or distributed through the system of the whole network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time when a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s record list. We explained more about blockchain security.

It's a decentralized system that is maintained by multiple computers or participants. A decentralized database can be managed by multiple participants.

It's called Decentralized Ledger Technology (DLT). 

Blockchain Technology is also a part of DLT where the transactions are recorded with an unchangeable cryptographic indication. This cryptographic indication is called the "Hash" !! Now, you may think that what is Hash?

Basically, it's a cryptographic hash function is a numerical calculation that maps information of self-assertive size to a piece exhibit of a fixed size. It is a single direction work, that is, a capacity that is for all intents and purposes infeasible to upset or opposite the calculation. In a perfect world, the best way to discover a message that creates a given hash is to endeavor a beast power search of potential contributions to check whether they produce a match, or utilize a rainbow table of coordinated with hashes. Cryptographic hash capacities are an essential instrument of present-day cryptography.

Why is blockchain technology becoming very popular? :

Blockchain is becoming very popular day by day !! But what's the main reason behind this ?? Blockchain is becoming very popular for its high data encryption and security. 

Our world technologies are advancing very fluently. It will be more and more advanced in the future. 

As technologies are growing, the loopholes and security breaches are also growing among them !! So, it's very essential that we have to fix the security problems of our technology and data and protect them properly.   Right ??

Here Blockchain Technology can be the best solution to secure and protect our data properly. Blockchain Technology is called an " unhackable technology ". Let's explain more below:-

Why blockchain is unhackable? :

As every record that has been written on the blockchain, it is secured by a unique cryptographic key. This key is actually unhackable. When a new record is written on the same block everything from their previous record, including its record and its key, is put into a formula to generate the key of the second record !!

Here, this interaction creates dependency !! And when the third record has created the contents and the keys of the first two records are put into a new formula to generate another key of the third formula !! This system is repeated again and again until the block is full. This dependency essentially makes the chain of all records together.

And now, this chain makes any data unhackable in the blockchain !! Because, if any hacker wants to hack any data from blockchain then the hacker has to breach or hack the whole blockchain, which is quite impossible !! So, it's a very secure technology.

In this way, every record created makes it dramatically more complex to alter history, because it's an open network so anyone can verify if the history is correct just by looking back at the previous blocks. 

Blockchain in transactions:

Blockchain makes transactions from peer to peer. Didn't understand?

OK. Let's explain. Blockchain makes a direct transaction from the sender to the receiver. No third-party authority or government can intervene in this transaction. Blockchain is an arrangement of recording data that makes it troublesome or difficult to change, hack, or cheat the framework. A blockchain is basically a digital ledger of transactions that is copied and circulated across the whole organization of PC frameworks on the blockchain. 

Blockchain is a secure and safe way of digital transaction. Now, think for a sec, when you transfer money to a person then you have to use your Bank Account, or PayPal, or your Debit Card or Credit Card. Here is a specific authority that validates and controls your transaction. So, here you and the receiver have to trust that authority. 

But in the transactions of Blockchain, there is no specific person or authority to intervene on your money or transactions. All computers on the Blockchain network validate your transactions and make them fast and secure. Blockchain makes a direct transaction from the sender to the receiver. No third-party authority can intervene in this transaction. That's a very trusted way for transactions !!

So, that's all for our today's discussion about Blockchain. This technology is using now to mine cryptocurrencies and transaction cryptocurrencies. But it will be used in all sectors for security soon. If you have any questions or query you can ask us in the comment below. We'll try our best to give the answer.

So, Stay Happy Stay Cool.
