What is Blockchain: Features and Use Case | Everything You Need to Know About Blockchain Technology

Friends, we let you know about different business ideas and digital marketing. And today we are going to discuss such a topic that topic is called What is Blockchain Technology And How Does It Work?
Many of you may have heard of blockchain. And if you haven’t heard the name of the block boy, you must have heard the name of Bitcoin, the king of the digital currency world. Since you know about Bitcoin, it will be much easier for you to understand what a blockchain is. Because Bitcoin’s record-keeping technology is called blockchain, and blockchain works in a variety of formats, such as banking and investment, in addition to digital cryptocurrencies such as bitcoin. So it would be good for you to know about blockchain. And if you don’t know about Bitcoin then don’t panic, because today you will get the complete details of what blockchain is through this post. So friends you read this post in full. Let’s get started and learn about blockchain.

What is a blockchain?

In fact, blockchain is a kind of database. Now you may be wondering what is the database? A database is a collection of information that is electrically stored in a computer system. The database stores information and data in a table format so that searching and filtering of any specification can be done easily.
Blockchain’s purpose is to record and distribute digital information, but not to edit this information. Blockchain technology was first introduced in 1991. And this technology then came to the fore through Stuart Haber and W. Scott Stornetta. But blockchain real effectiveness began in 2009 with Bitcoin.

Why is it called blockchain?

This is called blockchain because blockchain collects information from groups, and these groups are called blocks. All of these blogs have limited storage capacity. Therefore, when the storage of the blocks is filled, that block is added to the block that is filled first, and this process continues. And this method creates a chain of blocks, which is why it is called a blockchain.

Blockchain elements

Blockchain elements come together to form a blockchain. This blockchain is a chain of blocks where information stores are located. Each block has a cryptographic hash (#) from the previous blog. This hash is generated in every transaction. And the generated hash consists of numbers and letters.
A hash is a connection that converts the input of letters and numbers to an encrypted output of a flex length. This hash does not only depend on the transaction, but also on all the transactions that were shot before the new transaction was known. If a small change is made to the transaction, a new hash is created. Clearly, this means that if any changes are made to the settings of the blockchain then all the settings of the blockchain will be changed. In this way, the fraud in the records of the blockchain is detected. So blockchain is a secure option.
Blockchain performs transactions across multiple computers, and each computer has a copy of a specific blockchain. These computers are called nodes. These nodes check the transaction hash of the system to find out if there has been any change in the transaction. And if most of the nodes approve the transaction, then that transaction is written in blocks. These nodes blockchain infrastructure found.
It stores, spreads, or preserves blockchain data. These computer nodes have a complete copy of the blockchain transaction. This blockchain updates itself every 10 minutes.
We have learned how blockchain works and what are the elements associated with blockchain, now let us know how blockchain works for bitcoin.

How blockchain works for bitcoin

Blockchain for Bitcoin is a specific type of database. And from the data store of every bitcoin transaction in this database. In cryptocurrencies like bitcoins, blockchain spreads this currency option to computer networks. Which makes it possible to operate these cryptocurrencies without any central authority. The risk of using blockchain in cryptocurrencies such as bitcoins is much lower. And other processing and transaction fees of digital currency are eliminated.
The blocks in Bitcoin’s blockchain store it for monetary transactions. But blockchain tends to be reliable for storing other types of data here.

Blockchain Useful Area

Banks using blockchain

There are many areas where blockchain can be useful. And can secure and improve the services of various important authorities and sectors. If we differentiate between banking and blockchain, you will see that most of the time in a financial institute there are five working days in a week, if you deposit your check in those other two days then you have to wait for 2 days. And even on working days, if you deposit your check, the transaction still takes a lot of time. If the bank starts the transaction process through the integrating blockchain here, then all the transactions can be completed in 10 minutes.
Fund exchange between banks and institutes can be done very fast through blockchain. The blockchain can also be effective in the case of the health department, in the health department by keeping the patient’s important documents stored in the blockchain, keeping documents secure. Medical records and signatures in the health department can be stored in the blockchain. This will allow the patient to know that his record can no longer be changed. And while the “private key” can be used when storing these records in a blockchain, it will also have the privacy of the document.

Use of blockchain in supply chain and voting system

Supply chain and voting system block signs can be used. In the supply chain, the supplier can keep the details of the materials he has bought in the blockchain. Through this, the authenticity of that product can be verified.
And in the same way, fraud can be stopped by using blockchain in modern voting systems. Transparency can also be kept in this blockchain protocol. And thus block boys can be used in many sectors. The use of blockchain has both advantages and disadvantages.

Advantages and disadvantages of blockchain


The advantage of using blockchain is that accuracy can be improved through transparent technology. Money may cost less if third-party verification is not required. At the same time, transactions can be kept secure and private through blockchain.


The disadvantage of this technology is that this technology is not free. To speed up blockchain transaction speeds, blockchain technology can perform limited transactions every second. And this blog chain is used for illegal activities.
Friends, these are some of the information you need to know about the block, so you must share the information in this post with your relatives and friends.
