The global Blockchain market generated revenue of $3.0 billion in 2020, and it is expected to reach $39.7 billion by 2025 with a growing CAGR of 67.3% during 2020–2025.

The surging demand for simplifying the business processes and supply chain management apps deploying the Blockchain technology is driving the entire Blockchain market.

Looking at such a huge number of the growing future of Blockchain, you must be wondering what this hype is all about or how can this Blockchain technology actually help you in your business. Right? Great!

Today, in this blog, we will try to cover every significant and minute detail on Blockchain technology, Blockchain app development, and how Blockchain technology is going to help you in your business, whether you are a startup, enterprise, or SME.

Now, first thing first.

Firstly, we will have a brief look at what is Blockchain and why this technology is so popular?

So, What is a Blockchain? Why is Blockchain technology so popular?

A Blockchain is a list of stored records called blocks that store public data publicly and also in chronological order. The details are encrypted using cryptography to guarantee the privacy of the users is safe, and data is not altered or tampered with.

In a layman language, a Blockchain is a chain of blocks in which each block has its own transaction details, hash, and previous hash.

Let’s understand this with a very simple example-

Have you ever heard or used a Google doc?

I think you must have!

So, Blockchain technology is just like google doc. Wondering how?

In Google Docs, when we create a document and share it with other people or a group of people, the doc is distributed instead of transferring or copying. This process creates a decentralized distribution chain that allows everyone accesses to the doc at the same time.

No one needs to wait to get any permission from another party to make any modification, while all transaction is being recorded in real-time, making everything completely transparent.

No doubt, Blockchain is quite complicated than a Google doc while using it, but for that, you can anytime hire Blockchain experts for consultation.

Now, the next question that arises here is how does this Blockchain technology actually work?

How does this Blockchain technology work?

In recent years, you have definitely noticed that the majority of businesses across the globe have integrated Blockchain technology. But, actually, how does this technology work?

  • Cryptographic keys
  • To store the records & transactions of the network.

To deploy and extract the benefits of Blockchain technology to the fullest, what you need to do is, hire Blockchain developers.
