Since the internet's earliest days, identity and security have been key topics linked to both the growth of the digital age and the difficulty of finding a secure place within it.
A worthy, but daunting target, today's tech giants still struggle with the internet's open nature while at the same time trying to secure other securities with it. Passwords, queries, and the well-known prompts of "I'm not a robot" are time-tested solutions that keep us safe among an ever-increasing online population.
But they really do?
What if there was protection in the community? What if the online transactions were successful, transparent, and secure? What if all that you digitally transmitted can be done in this way?
Blockchain technology could be the answer to these questions very well. It also has the latent to be much more competitive for companies. In this post, we are going to know about Blockchain technology and how it is transforming the world.
What is Blockchain?
A blockchain is at its core a series of computers or "nodes," which together form a network of transactions or digital ledger. When new transactions occur, the blocks are made, the ledger is changed, and all nodes have the latest ledger immediately and use heavy-duty power cords and power supplies.
Think of it as a database updated and added by multiple users, each of whom has access to the latest, most up-to-date version.
The secret behind the blockchain concept is that the database is not stored either in a central entity or at a single location. Alternatively, the various nodes that make up the network are shared and managed.
The Blockchain technology emerged in 2009, with the arrival of Bitcoin. With the help of Blockchain, digital information can be easily exchanged without taking the services of any external user.

From where the requirement of Blockchain technology came
Computers store and organize data on a database-most commonly known as a relational database. Relational databases are like sophisticated Excel spreadsheets as they organize information in columns and rows consisting of different tables.
Such tables are then stored on hard drives that can be accessed through the internet via servers.
Users can use special instruction known as a request to add, modify, delete, or retrieve information from a relational database. But as more information is added to a database and a growing number of people attempt to retrieve it, computers need to work harder to handle the ever-increasing number of requests addressed to them.
Blockchain technology challenges dynamic regulation. Blockchain is an alternative way of saving and transmitting data between computers, all while keeping it secure, private, and decentralized-sort of like an extremely secure database that no one owns.
How Blockchain works
People kept their significant documents secure before computers, by creating lots of copies and keeping them in dense steel safes, secret treasure chests, or bank vaults. You'd be translating each of these documents into a secret language as an added security precaution that is only understood by you.
In this way, if someone able to break your bank vault and take your stuff, still he is not able to read your message, and also, you have backups that are stored in different locations.
In the Blockchain technology, special files are encrypted so that it becomes hard for others to understand it and such files are saved stored on computers which are linked together through the internet.
These files are known as ledgers, the computers are known as nodes or blocks, and the internet or network is known as a chain. The chain is a series of linked blocks that allow computers to work together and share ledger. This is Blockchain.
Important Characteristics of Blockchain Technology
The Blockchain technology offers some important characteristics which make it better than other technology. So, look at these characteristics of Blockchain technology more closely;
Distributed Ledgers
There are millions of copies of each database that are regularly updated by the person who is connected to the server. Imagine there is a spreadsheet that contains digital records of various things. Whenever that sheet is modified on any of the computers, it is replicated, synchronized, and shared so that these changes are updated in all other computers linked to the server.
Peer-to-peer network
It is a network of computers that allow devices to combine their power and to complete the task at higher speeds. In this network, computer systems are connected to each other over a server. In this network, there is no requirement of a central server, and each system becomes a server and a client.
Hash Function
It is a type of software that helps in encryption. In this a message is taken by hash, then it is converted into a code, and it becomes impossible for anyone to decode the message without having a signature or key.
Immutability
It is an important feature of Blockchain technology that provides security to the transaction. With having this feature, it becomes impossible for anyone to change or transform data without having permission.
Pseudonymity
This feature allows users to decide whether they want to share their identity with others or want to remain unidentified on the network.
