What is Blockchain Technology? Step-by-step guide for beginners.

What is Blockchain Technology?

This technology of blockchain allows companies to store digital records of every transaction made on a specific platform. Blockchain technology is basically a digital ledger file that keeps track of all your financial records. Just like pages in a book, they are numbered and show up in chronological order. The blocks are included in chronological order with the most recent timestamp framing a chain of blocks. Blockchain technology deals with a progression of blocks of data hash-tagged together with the end goal that each block contains a hash-tag grouping of the past blocks. 

This technology has several benefits such as transparency, decentralization, and security. Transparency is the benefit of this technology means that the data stored is visible to everyone. This transparency makes it harder for individuals to take part in fraud transactions. Blockchain technology is viewed as a secure system since cryptology is utilized to ensure that no one can blend with the timestamps or blocks. This makes it ideal for taking care of information structure and to monitor records of whatever is important. Blockchain is only updated by consensus between members in the system, and once new information is entered it can never be deleted.

A blockchain is an option giving decentralization of information which in any case was kept up by the central server. Thus, anything that is based on the blockchain is transparent and everybody involved is responsible for their activities.

Do you know why blockchain has so much buzz among people?

.

The answer is BITCOIN (wildly hyped Cryptocurrency). 

Initially, blockchain was created to support bitcoin but the tech industry has started using this technology for many purposes. This Bitcoin considers installment transactions over an open network utilizing encryption and without revealing the name of individual bitcoin owners.  Bitcoin is also a steady asset such as gold or traditional fiat currency. Blockchain is likewise being utilized to digitize other assets, for example, vehicles, land, and even work of art. Like Bitcoin, Wikipedia is also an example of Blockchain. 

How does Blockchain Work?

Blockchain is the best invention on the internet itself. It permits value exchange without trust or central authority. The database of blockchain can be visible to anyone and easily verifiable, it cannot be stored in any single location. Hackers cannot corrupt that information as this information has no centralized version. Its information is public on the internet.

The reason behind why the blockchain has picked up so much appreciation is that:

      1. It is not owned by any authority, therefore it is decentralized.
      2. The information is cryptographically stored and never erased.
      3. The blockchain is immutable, so no one can tamper with the data inside the blockchain
      4. Blockchain is transparent so they can track data if they want.

One thing is clear: regardless of whether cryptographic forms of money like Bitcoin end up being a craze, the fundamental blockchain technology focuses on a set of tools that could change the essence of how business is directed in each area of the economy.

Three Primary Components of Blockchain Technology

To make this easy, let’s have a look at three primary components of blockchain;

      1. Decentralization
      2. Transparency
      3. Immutability

Without these three parts, this technology won’t have the option to deliver any specialized capacities.

1. Decentralization

Decentralization refers to the ability for members to share data without a central authority controlling the network. Every individual from the blockchain system has access to the entire database. As opposed to the central-based system, consensus algorithms allow for control of the network. In a decentralized network, the database is not stored in one place. On the off chance that you needed to communicate with your companion, at that point you can do so directly without going to a third party. That was the primary philosophy behind Bitcoins. You and just only you are the owner of your money. You can send money to anyone without going to the bank.

2. Transparency

There are so many questions people ask about blockchain technology. Some people have doubts.  What do you think, Blockchain gives you privacy, or is it transparent? 

So, now let me clear your doubt. 

The person’s identity is cryptographically stored i.e. it is hidden but you can see that person’s recent transaction or transaction history by their public address. Example: if John sent you 1 BTC, you will not be able to see the name, it will show you like,1BG1mHJiDzzz8bvPYEadhT2ThyFt5DZP sent you 2 BTC. 

In this way, while the individual’s personal identity is secure, you will be able to check all the transactions that were finished by their public address. This transparency level has never existed inside a monetary system. Due to the decentralized idea of Bitcoin’s blockchain, everything exchanges can be transparently seen by either having an individual hub or by utilizing blockchain explorers that permit anybody to see transactions happening live. This means that if you wish to track bitcoin wherever it goes, you can do so.

However, the blockchain system can’t be hacked. This is probably not going to occur, as it requires a huge computing system to overwrite the blockchain network completely. 

3. Immutability

Immutability can be explained as any data stored in a blockchain cannot be tampered with or erased by anyone. The security of cryptocurrency needs to be both resilient and immutable. Resilience or resilience in the short term means to be able to protect or recover from short attacks and Immutability in the long-term means impossible to alter and delete data. 

Each block of data, for example, transaction details or facts, continue utilizing a cryptographic rule or hash esteem. These blocks contain transactions that have a place with a dropped chain. That hash esteem comprises an alphanumeric string produced by each block individually. Each block not just contains a hash or computerized signature for itself yet additionally for the previous one. This function of blockchain technology guarantees that nobody can interfere or change the information stored in the block.

This consensus guarantees that the originality of information must be kept up. Without a doubt, immutability is a conclusive element of this technology. This model has the power to redefine the data auditing method and makes it more proficient, cost-effective, and carries more trust and integrity to the information.

Benefits of Blockchain Technology

Let’s have a quick look at Blockchain benefits. Here are the remarkable benefits:

        1. Transparency: Immediately notified you once your transaction completed, which is convenient and trustworthy.
        2. Security: Blockchain is a highly secured system because of its computerized signature and encryption. The system is specially intended to be secure,tamper-proof, and convenient.
        3. Fraud Control: There is no centralized place in the database, so it is not easy for hackers to get access or corrupt any data easily.
        4. No hidden fees: In a decentralized network, no need to pay any fees or commission to intermediaries.
        5. Account Reconciliation: The validity of transactions is checked and affirmed by members, consequently, they additionally affirm their own authenticity.
        6. Speed: Money can be transferred to anyone in just a few minutes, and all the transactions can be viewed as secure. No need to add third party payment systems, which reduce the cost and increase the processing speed.
