Blockchain is a website of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. 

If you friend the BlockChain is a public and distributed ledger, where the records of each Bitcoin transaction are stored for a period of time.

It's a good description and explanation for blockchain. It seems to me that it is very secure, not simple and easy to hack, and this is new information for me

[md.nayem01 0]

The present era is the modern age. In this modern age, people do modern things. Many work online to earn a living. I also work online. I earned $ 1000 BTC from crypto at one go. I invested $ with Telegram. I converted crypto into money with the bank. General Chat Chat LoungThe way the crypto currency is advancing suggests that there will be more growth in the future.

[Sabaali1600 461]

Thank you so much for your precious information.

With my knowledge , Blockchain is the most important aspect of crypto currency and it is very good and we have started realizing the importance and application in other areas. It also has the advantage of future home business development. 

[aameelia 208]

your sharing is very wonderful and explain the details very clearly according to forum rules i shall be very thankful to you and in my opinion blockchain is essentially a digital ledger and record of transactions and it is a safe way to use and record the information.

[Sajimalik 489]

In just simple word blockchain is just a cloud database right there where each blocked has a hash and getting duplicate and make another hash to make it secure.

[Kenda6666 850]

Blockchain technology is one of the latest technologies in the world of technology and the world of cryptography, as it protects our money and transactions from theft. I have heard a lot about this technology and it has helped me a lot with your topic. Thank you very much, my friend, for this wonderful and useful post.

[Sheshimmers 103]

This was really very helpful indeed. We need such content on this forum especially in the beginners section, we really need explainations such as this to enhance the understanding of the beginners. This was easily understood by me who is someone who has no idea how cryptomoney works. Thanks very much. 

[asmar33 413]

Thanks my friend for this clarification. You seem tired to share it. It is a wonderful technology that provides several advantages, the most important of which is the safety feature, which everyone uses in the first place.

[johar12233 310]

Thank you for this information. Yes, blockchain technology is the best technology that has happened so far in the field of financial transfers because it helped a lot in shortening the large time that banks and bank cards take and helped to maintain complete confidentiality in the transfer operations.

I think the most important feature of the Bitcoin project is the blockchain!
And I think that had it not been for the blockchain, we would not have seen Bitcoin as we do today!
System security and safety is very necessary for any user!
Users cannot trust any project until they see that this project guarantees the safety and security of their money!
Your article is very impressive and I wish you good luck in the next submissions!

It is true that in the past Bitcoin was without any value. Only a few people bought and kept Bitcoin. It was really crazy.

Before 2009

we were living in the era of the Internet of information. This era helped billions of people all around the world to communicate with each other. But when it was first designed it was not designed for peer-to-peer payments. 

 

Then suddenly something new happened.

In 2009

When someone named Satoshi Nakamoto

lunched something he called Bit Coin.

Which is a peer-to-peer electronic cash money system.

 

In search of trust protocol and amid the market meltdown, Satoshi Nakamoto outlined the 

Blockchain Technology.

 

We call Blockchain 

THE TRUSTED PROTOCOL.

 

It was made for people who do not know each other and with no reason to trust each other. This Protocol do two main duties.

1- Preserve the integrity of people transaction.

2- It is not through powerful intermediaries( like banks ) it is through mass collaboration, cryptography and clever codes.

 

And the main question comes here, What is Blockchain ??

 

 

Blockchain is the technology behind digital currencies (Cryptocurrencies) like Bitcoin.

It is an open source code, anyone can download it for free, run it and use it to develop new tools for managing transactions online.

It is a protocol not a product, it is a chain of blocks.

 

Big banks and some governments are using Blockchain to revolutionize how they store information and conduct transactions.

Blockchains have an interesting property: once some data has been recorded inside a blockchain it becomes very difficult to change it.

 

Lets take a closer look at a block from a blockchain.

Each Block consists of three main elements:

1- Data.

2- Hash of the block.

3- Hash of the previous block.

 

 

And now, lets explain these three elements.

1- DATA.

The data that is stored inside a block depends on the type of the Blockchain. For example, The Bitcoin Blockchain stores the details about transactions such as the sender, receiver and the amount of coins. And the data that is being stored in the block could be different from a chain to another depending on the type of the Blockchain. 

 

2- Hash.

A block has a hash you can compare it to a fingerprint. It identifies a block and all of its contents and it is always unique.

Once block is created its hash is being calculated, and changing something inside the block will cause the hash to change.

 

Hashes are very useful when you want to detect changes to blocks. If the fingerprint of a block changes, it is no longer in the same block.

 

 

 

3- HASH OF PREVIOUS BLOCK.

 

 

This effectively creates a chin of blocks and it is that technique that makes a blockchain so secure.

Here we have an example of a chain consists of three blocks. Each block has a hash and the hash of the previous block. 

The first block is always special, it can not point to a previous block because it is the first block, so that we call it the GENESIS BLOCK.

 

If you tampered with the second block, or someone tried to edit the data in that block, this will cause the hash of the block to change as well. In turn, that will make block number three and all the blocks after the following blocks invalid because they no longer store a valid hash of the previous block. 

 

 

So that the answer of the following question will be:

 

Why to use Blockchain ??

 

The reason behind using Blockchain technology:

1- Provides faster speeds.

2- lower costs.

3- Greater security.

4- Fewer errors.

5- Eliminates central points of attack and failure.

 

I hope that this information could help newbies to learn more about Blockchain and how it started.

And please support me with your information.

 

 

 

In the past, Bitcoin was only a cent, and there were no people actually buying it. The faucets used to pay five pieces with a bitcoin, and today you only pay one Satoshi.

This technology is what gives us confidence and a sense of security when working with cryptocurrencies, as it guarantees safe and documented transfers with great speed, without fear of exposure to any hacking or theft.

Thanks for these useful information my friend,Blockchain is the notebook of the digital teacher in which the recording transactions happen,and it depends on encryption to confirm security and credibility. It features decentralized processes for increased productivity and tamper-resistance.
