What is Blockchain

If you want to pay online, you need to register an account and provide credit card information. You can also pay by bank transfer if you don’t have your credit card. These methods could become obsolete with the advent of cryptocurrencies.

Imagine a world in which you can do transactions and many other things without having to give your personal information. Imagine a world where you don’t have to rely on banks and governments anymore. It sounds amazing, right? This is exactly what blockchain technology allows us.

It’s like your computer’s hard drive. Blockchain is a technology that allows you to store data in digital blocks. These blocks are connected together like links in an a chain.

Blockchain technology was originally invented in 1991 by two mathematicians, Stuart Haber and W. Scot Stornetta. The system was originally proposed by W. Scot Stornetta and Stuart Haber to ensure that timestamps couldn’t be altered.

A few years later, in 1998, software developer Nick Szabo proposed using a similar kind of technology to secure a digital payments system he called “Bit Gold.” However, this innovation was not adopted until Satoshi Nakamoto claimed to have invented the first Blockchain and Bitcoin.

So, What is Blockchain?

A blockchain is a distributed database shared between the nodes of a computer network. It saves information in digital format. Blockchain technology was first discovered by many people when they began to search for information about bitcoin.

Blockchain is used in cryptocurrency systems to ensure secure, decentralized records of transactions.

Blockchain allowed people to guarantee the fidelity and security of a record of data without the need for a third party to ensure accuracy.

To understand how a blockchain works, Consider these basic steps:

  • Blockchain collects information in “blocks”.
  • A block has a storage capacity, and once it’s used up, it can be closed and linked to a previously served block.
  • Blocks form chains, which are called “Blockchains.”
  • More information will be added to the block with the most content until its capacity is full. This process continues over and over again.
  • Each block in the chain has an exact timestamp and can’t be changed.

Let’s get to know more about the blockchain.

How does blockchain work?

Blockchain records digital information and distributes it across the network without changing it. The information is distributed to many users and stored in an immutable permanent ledger that cannot be changed or destroyed. Blockchain is also known as “Distributed ledger technology” or DLT.

Here’s how it works:

  • Someone or a computer will transacts
  • The transaction is transmitted throughout the network.
  • A network of computers can confirm the transaction.
  • When it is confirmed a transaction is added to a block
  • The blocks are linked together to create a history.

And that’s the beauty of it! Although it may seem complicated, the process is possible with modern technology. Technology is rapidly changing, so I expect things will move faster than ever.

  • A new transaction is added to the system. It is then transmitted to a network computers located all over the globe. The computers then solve equations to verify the authenticity of the transaction.
  • Once a transaction is confirmed, it is placed in a block after the confirmation. To create a permanent history of each transaction, all blocks are linked together.

How are Blockchains used?

Even though blockchain is integral to cryptocurrency, it has other applications. Blockchain can be used to store reliable data about transactions. Many people confuse blockchain and cryptocurrencies like bitcoin or ethereum.

Blockchain already being adopted by some big-name companies, such as Walmart, AIG, Siemens, Pfizer, and Unilever. IBM’s Food Trust, for example, uses blockchain to track food’s journey to its final destination.

Although some of you may consider this practice excessive, food suppliers and manufacturers adhere to the policy of tracing their products because bacteria such as E. coli and Salmonella have been found in packaged foods. There have been isolated cases in which dangerous allergens like peanuts were accidentally introduced to certain products.

Tracing and identifying the sources of an outbreak is a challenging task that can take months or years. The Blockchain allows companies to track the origins of their food and prevent future outbreaks.

Blockchain technology allows systems to react much faster in the event of a hazard. It has many other applications in modern society.

What is Blockchain Decentralization?

Blockchain technology is safe, even if it’s public. The technology can be accessed via an internet connection.

Have you ever been in a situation where you had all your data stored at one place and that one secure place got compromised? It would be wonderful if there were a way to keep your data safe even if your storage systems are compromised.

Blockchain technology provides a way of avoiding this situation by using multiple computers at different locations to store information about transactions. The transaction will not be affected by any of the computers that have problems.

Instead, other nodes will use the correct information to cross-reference your incorrect node. This is known as “Decentralization”, which means that all information is stored in multiple locations.

Blockchain guarantees your data’s authenticity–not just its accuracy, but also its irreversibility. It can also be used for data storage that is difficult to register, such as legal contracts, state identifications or company product inventories.

Pros and Cons of Blockchain

Blockchain has many advantages and disadvantages.


  • Accuracy is increased because there is no human involvement in the verification process.
  • One of the great things about decentralization is that it makes information harder to tamper with.
  • Safe, private, and easy transactions
  • Provides a banking alternative and safe storage of personal information


  • Data storage has limits.
  • The regulations are always changing, as they differ from place to place.
  • It has a risk of being used for illicit activities

Frequently Asked Questions About Blockchain

I’ll answer the most frequently asked questions about blockchain in this section.

Is Blockchain a cryptocurrency?

Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It is a digital ledger that records all transactions seamlessly.

Is it possible for Blockchain to be hacked?

Yes, blockchain can be theoretically hacked, but it is a complicated task to be achieved. It is difficult to hack the blockchain because it is constantly reviewed by a network of users.

What is the most prominent blockchain company?

Coinbase Global is currently the biggest blockchain company in the world. The company has a solid infrastructure, services, as well as technology to support the digital currency economy.

Who owns Blockchain?

Blockchain is a decentralized technology. It is a network of distributed ledgers that are connected to each other. Any electronic device can be a node. Blockhain is thus one’s own blockhain.

What is the difference between Bitcoin and Blockchain technology?

Bitcoin is a cryptocurrency, which is powered by Blockchain technology while Blockchain is a distributed ledger of cryptocurrency

What is the difference between Blockchain and a Database?

Generally a database is a collection of data which can be stored and organized using a database management system. Anyone who has access to the database can view and edit the data. Databases are implemented using the client-server network architecture. A blockchain, on the other hand, is a growing number of records (called blocks) stored in a distributed system. Each block contains a cryptographic haveh of the previous block, timestamp, and transaction information. Due to the nature of the blockchain, data cannot be modified. Blockchain technology allows for decentralized control and eliminates the risk of data modification by third parties.

Final Saying

Blockchain has a wide spectrum of applications and, over the next 5-10 years, we will likely see it being integrated into all sorts of industries. Blockchain could revolutionize how we store and share information, from finance to healthcare. Although there is some hesitation to adopt blockchain systems right now, that won’t be the case in 2022-2023 (and even less so in 2026). Owners, CIOs, and entrepreneurs will all be able to use blockchain technology for their own benefit once they become more familiar with it.
