What is Blockchain?

[kafkas78 31]

The fact that we can briefly say 'Encrypted and Unchangeable Recording System' for Blockchain, but this does not make much sense for a person who is far from technology, right?

You're right :) Then let's tell a little bit more simple story about this technology called Blockchain.

Let's go back years ago; When we go to the grocery store with a credit book and buy something, the grocery store would write this shopping both in its own notebook and in our notebook.
The reason for this two-sided writing process was to prevent one of the two parties from doing a recording or deletion without knowing each other.

Here is the working logic of the Blockchain system, the record entered into the system is kept simultaneously with all users in the system, and when a user tries to change his / her information without the consent of other users, it will not be accepted by the system because it will not be the same as the records of other users.

To be specific, Blockchain technology allows us to keep our data in an immutable and secure way. In addition, one of the main reasons why this technology is so valuable is that it does not need a center.

Many world giants such as IBM, Walmart, Unilever and Nestle have already started to use this technology. In addition, Georgia has now begun to test this technology in title deed transactions.

It is a chain of single record blocks that is distributed in several nodes of a network, and if we talk about cryptocurrencies it is like an accounting book where each of the transactions carried out is recorded.

Blockchain technology helps the users to mine cryptocurrencies such as Bitcoin with the help of a software which is quick and efficient in terms of its capabilities. So you so who has more up to date and innovative software can make the process more time saving and productive. You just need to install the necessary steps into your desktop in order to start mining. There are many users who had gained profitable from this.

As far as I know, the Blockchain is like an account book where everything is registered where nothing can be modified or altered by hackers where it can also be used in addition to cryptocurrencies in various fields such as medicine and other fields.
Good luck and big winnings for the whole community
A big greeting

Thank you so much for sharing such an important post about blockchain with me. I have had very little knowledge about blockchain before. Now I know a lot

[mohamedpc1 2213]

i think Blockchain technology helps the customers to mine cryptocurrencies along with Bitcoin with the help of a software program that is quick  in phrases of its skills. So that you so who has greater up to date and revolutionary software can make the process extra time saving and efficient. You just need to put in the important steps into your laptop a good way to start mining.

Blockchain, in short, is like a ledger and it records and handles transactions without a third party and is characterized by several advantages, including privacy and great security

[Arslanbhai123 628]

Fabulous information first time i  listened about this word so i searched it on gogle and learn something about it. Tha ks for posting this topic. 

Blockchain is a system that makes it difficult or impossible to change, hack, and cheat the system. Each block in the chain conatian information about transaction and when new transaction it conatin infor about the participants ledger. 

[Batulaedozhigi 101]

Blockchain is a technology that has made a lot if things possible, it has solved what has been a big issue in the financial sector which is double spending. The blockchain has really made the concept of decentralization a reality and the power now belongs to the people.

[Najmul2034 195]

Blogchain is a secure place. Various government and private documents can be kept here. Here you can keep your secret sources.  But I don't know much about it. As far as I know, I told you. This blog chain is a safe place.

[Zafar123 906]

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. ... Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant's ledger.

[Culture58 338]

Hy with this post, I fully understand the meaning and function of block chain  and I fully convinced with this little explanation. Thank you

Blockcahins is a specific type of database. Blockcahins store data in a blocks that are then chained together. Blockcahins is used in decentralized way so that no single person or group has control. Blockcahins are immutable which meansthat transaction are permanently recorded and viewable to anyone.

[TimopheyKa 3900]

Blockchain literally translates as a chain of blocks.
In simple words, it is several identical data (files, databases, etc.) that are stored on different computers. If there are changes in one block, the data on the other blocks will also be updated. If a block with new data is formed, it is checked by other network participants (computers). if everyone agrees, then everyone will have changes.

What is it needed for?

 

1) power Distribution. Blockchain is a system where there is no Central computer. All network participants are equally equal. Computing power is distributed evenly.

2) Security. Since there is no main computer, hacking each block and its copies is very, very difficult and time-consuming.

3) Openness. All this database is in the public domain. You can find out what events/actions were performed. But specifically who took part-here if the participants themselves want to publish this operation.

4) there Are no intermediaries. All actions are performed directly, without banks, notaries, etc.

In General terms, based on the technology of the blockchain and mined cryptocurrency.

[Simon London 1749]

Hello everyone, the Blockchain can be defined as a public record of digital operations, which allows each person and device to be identified and to keep track of all their transactions and operations, this technology will serve to make the world more secure and that people we have personalized products.

[luis1410 504]

Blockchain isn't just about cryptocurrencies, of course. Is blockchain a planet on which essentially the digital world will be built? We grasped the logic of the work more or less. Some kind of notary. In short, it is a system where data is stored in all computers of the world. But is that all? For example, there are passport-free gates at newly built airports. Thanks to facial recognition systems, it will be possible to pass through the airport without the need for a passport. Will you have to register on the Blockchain to participate in the facial recognition system? Many blockchain-based technologies are being developed and will soon become indispensable by humans. For example, can digital countries be established on Blockchain in the near future? Is it possible to get citizenship from these digital countries? In this case, you may even be subject to the laws of the digital country in which you are registered, not the country where you live. Could these be some kind of conspiracy theory?

[Izeal 4404]

Yes, blockchain is the transparent and secure ledger book where all the transactions of the bitcoin are kept in the systematic way. As you have said that it is used my many companies and I am sure many more countries will accept this technology.

[bhaiegoo 1517]

Blockchian is made up of two words, one is 'block 'which mean contain transaction history and other is 'chain' which mean links them.  Blockchain is technology which recorded our history and not allowed to spammer, hacker to give loss their users so it provide us full security to us. 

[Syman 520]

Thank you so much for presenting Blockchain in such a beautiful way and I learned so much about Blockchain through these topics.  Good and secure wallet in blockchain cryptocurrency wallet.  Coins can be stored securely in a blockchain wallet and can be traded quickly.  One of the advantages of a blockchain wallet is that transactions are faster.

[Michaelx018 0]

even though I have come across the term blockchain technology many times while in the forum ,this is the first time I am actually coming to know the real meaning behind it. this technology seems to be one of the finest because it does not need a centor or a controlling headquarter.

[RonaldB 48]

Blockchain is a modern technology, which many major companies have benefited from, which correct the preservation of data without the ability to change it without accepting its system for that, and this technology will spread to all major institutions and international banks in the near future

[Ahmad ah 1212]

I am a beginner and I do not know much about Blockchain. What I do know is that it is a wallet that is recommended for beginners. It is highly secure, good, fast, accurate and lots of good features that can be applied.
