What is Blockchain Technology and How Does It Work?

What is Blockchain Technology

Hello friends, today through this article we will tell you everything in detail about blockchain technology. What is the history of blockchain technology? Future of Blockchain technology? What does blockchain technology work on? What benefits of blockchain technology? We will tell you all this through this article.

Friends, blockchain technology is growing very fast in the world. Because cryptocurrency bitcoin and other currencies also work on the blockchain only. That’s why there is going to be a good scope of cryptocurrency and blockchain technology in the coming time.

What is Blockchain?

We can call blockchain a chain of different blocks, information is hidden in these blocks. The purpose of using blockchain is to timestamp digital documents so that they cannot be backdated or tampered with. The technology of blockchain can also get rid of the problem of two records without using a central server.

Using blockchain technology, money, property, agreements, etc. can be easily exchanged without the need for the mediation of a bank, government, or any third party. The specialty of this technology is that once any data is recorded inside a blockchain, it becomes not only difficult but almost impossible to change it.

History of Blockchain Technology

Blockchain Technology was invented by Satoshi Nakamoto in 2008 so that he could do it in cryptocurrency bitcoin, according to his public transaction ledger.

Satoshi Nakamoto’s main objective behind doing all this was that he wanted to create a decentralized Bitcoin ledger—the blockchain—which gives people the ability to control their money so that any third party, or anyone Even the government could not access or monitor this money.

Satoshi, the creator of Bitcoin, suddenly disappears in 2011, leaving behind this open-source software that Bitcoin users can use and update and improve.

Many believe that there is no person named Satoshi Nakamoto, it is just a fictional character. By the way, there is no correct information available about its veracity.

The invention of the blockchain for bitcoin is the first digital currency that can solve the double spending problem without the help of any trusted central authority or central server. That’s why this Blockchain Technology has also been the inspiration for many other applications.

How did the Name Blockchain Come About?

Blockchain is made up of two words. First block and second chain. Block refers to a number of data blocks in blockchain technology. This means the data is kept in these blocks. Different boxes contain currency ie data, and they are connected to each other. A long chain of data is formed. As new data arrives, it is entered into a new block. When a block is full, it is appended with new data. Similarly, all the blocks are connected to each other.

What is the Relationship Between Blockchain & Bitcoin?

Cryptocurrencies around the world, whether it is bitcoin or Ethereum, all use the technology of blockchain. The first and most well-known application based on blockchain is bitcoin, the world’s most famous peer-to-peer digital currency. Bitcoin is created and controlled by the technology of blockchain itself. Unlike traditional currency, you can transfer bitcoin based on blockchain technology to anyone and anywhere without any permission from banks or governments.

Cryptocurrencies like bitcoin or Ethereum, a digital currency based on blockchain technology, do not even care whether you are a human or a machine in the transaction. Based on blockchain technology, thousands of bitcoins are able to verify the validity of payments uniformly at the same time, so there is no need for banks or any third-party intermediaries for its operation.

Blocks are added to the Bitcoin blockchain every 10 minutes after being verified by crypto miners with the help of an inbuilt consensus mechanism. Each entry in these blocks is secured using cryptographic maths which makes it irreversible.

How Secure is Blockchain?

In this way, nothing is secure in the internet. On the other hand, if we talk about Blockchain technology, then it is “unhackable” to a great extent as compared to the rest of the technology. To do any transaction in Blockchain, all the nodes of the entire network will have to agree, only then that transaction will be valid. Here no single entity can say whether the transaction has happened or not.

To hack it, you will not have to hack only one system like a bank, but you will have to hack all the systems located in the entire network, so hacking is not such an easy thing in this technology.

The computing resources of almost all blockchains are tremendous because there is not one computer here but many computers are connected in the network.

The Technology Behind Blockchain Technology

The main technology behind blockchain is mainly the three technologies given below.

1. Private Key Cryptography
2. P2P Network (Peer-2-Peer)
3. Program (the blockchain’s protocol)

Why do We Need Blockchain Technology?

Blockchain is a mechanism that helps all of us reach our highest degree of accountability. Now there will be no missed transactions, it will reduce human and mechanical errors, and no third party or government’s consent is necessary behind all these transactions, but only trust or secure validation of all connected nodes matters.

The most critical area where blockchain helps us is to guarantee the validity of a transaction by recording them, this is not being done in just one main register but in all the registers of all the distributed systems connected in the network. Transaction will be called valid only after secure validation.

Future of Blockchain

By now you must have understood what is the utility of Blockchain and how it can be used in all our work. It has changed our thinking about information, how and where information can be stored, who can access this information, and what we can do with this information.

Which is the main reason why some organizations are against it because how we organize blockchain information and how we maintain our records-keeping infrastructure goes to the very heart of these things.

It is clear from this that people will not accept Blockchain Technology so easily and it is not going to come overnight because it challenges traditional technology at every step.

We had seen a similar case in TCP/IP, which was criticized a lot in the beginning. But later it took about 30 years to implement it. But finally, everyone understood its importance. In the same way, the world is still taking time to understand Blockchain. But it will definitely be adopted in a few years.

Opportunities in Blockchain Technology

  • This blockchain helps our smart devices to communicate with each other so that they can interact better.
  • Blockchain solves the problem of manipulation. It brings all things to the level of their highest degree of accountability.
  • Makes online identity and reputation decentralized. So that we can own our data ourselves.
  • Cryptocurrencies distribute the ability to control the value of currencies from the hands of the government to the general public so that now no one will have a hand over the value of currencies.
  • In an informal economy, blockchain saves us from the middleman so that assets can be exchanged easily and freely.
  • With the help of Blockchain technology, many issues related to freedom, jurisdiction, censorship, and regulation can be addressed correctly and smoothly.
  • With blockchain-based systems, there is no need to keep intermediaries anymore. But records and transfer of assets can be easily taken care of. Due to this the transaction speed increases.
  • Data that are once entered into the blockchain become immutable. Which cannot be changed in any way, which reduces the chances of fraud to a great extent. Apart from this, Transactions are very clear and can be easily investigated and audited later.
