What is Blockchain?

You might have already read over and over again about that complex and regular definition of Blockchain technology. Let’s simplify that for you. Imagine a giant Digital Lego that everyone or anyone can build, but no one can steal or break it.

This is what blockchain technology is, it uses digital blocks that are linked with the previous block which has information filled in it that can’t be tampered with or stolen creating an unbreakable chain of information. So, next time anyone uses the word Blockchain, you can imagine a tower of digital blocks that store and manage the information.

The features of Blockchain like data privacy and security have proved their worth whenever it has been used in any sector. Research says the same, Global spending on Blockchain solutions will hit $19 billion by 2024 covering from web to blockchain app development.

The main reason behind this popularity is its features including safety, security, decentralization, and more. Initially, it was for financial services but over time, it has grown its popularity among other sectors and industries. Getting blockchain development solutions for businesses has resulted in more transparency and efficiency and opened new gates of possibilities for them.

Below table show the distribution of blockchain market value by sector. Seeing this distribution, you will also make up your mind to discuss your requirement with a leading blockchain development companies and get a solution.

How Does Blockchain Work?

The working of Blockchain includes many terms and phrases related to any new technology that is always a hot topic of discussion. So, instead of re-repeating those terms and complex them.

We will understand the working of Blockchain technology step by step –

  • Step-1 – A new transaction will be requested by the user, then, there will be created a Block to represent the transaction.
  • Step-2 – The block will be transmitted to a peer-to-peer computer network (nodes) discrete worldwide.
  • Step-3 – The computer network will work on equations for the transaction’s validation.
  • Step-4 – Nodes will get the reward for PoW (Proof of work).
  • Step-5 – Then, these blocks will be added together in an existing Blockchain to create a history of permanent transactions.
  • Step-6 – The transaction is complete here.   

Usually, the working of Blockchain is based on three pillars- cryptography, nodes, and blocks.

Blockchain is a digital ledger that saves a complete database and transaction using cryptography so that the data can deal with and read by whom the information is projected. Each transaction is verified and recorded by a network of computers that is called nodes.

Once these transactions are recorded neither can change or be deleted. All the nodes in the blockchain save a copy of the blockchain and then come together to add a new transaction to the chain. Blockchain is distributed and decentralized, it is impossible to tamper with the data.

Back in 2009, Blockchain was launched in ‘’The great recession’’ period as a new digital currency to take away the power of central authority and make it decentralized among networks. Initially, Blockchain was launched as a technology supporting cryptocurrencies like Bitcoin, Ethereum, and others.

But, over the year, progressively they have shown more potential uses such as supply chain management, voting system, and many more. Every leading blockchain development company uses some programming languages to build its solutions. Below we will disclose them, their pros, and cons, and study their use cases of them. Let’s dive in-

Why Programming is Required in Blockchain?

To understand Blockchain deeply, Let’s understand the basics starting from the programming language in Blockchain –

Imagine you’re playing a game of chess, but instead of playing on a physical board with moving pieces, you decide to use your computer to play the game. To play with the computer, the system needs to understand the rules and set of instructions of the game to recognize your move and reply. The programming language comes to help by interpreting your moves that are how programming languages work.

Similarly, every new technology even Blockchain is written in computer language or specific languages such as Solidity, Java, Python, PHP, and C++ by developers to understand and execute instructions related to Blockchain technology. To understand the rules of Blockchain and to translate your moves, programming language come as a helping hand.

programming langauge quotes

Without programming languages, it is not possible to make smart contracts, build decentralized applications, or interact with the Blockchain in any meaningful way. But, you might think programming tools are not just any tool that is necessary for Blockchain development. But from a developer’s point of view, it can be a lot of fun too.

Imagine writing a few lines of code and seeing your ideas coming to life on Blockchain. It must be satisfying. Isn’t it? Not only this, but it also increases your knowledge and improves problem-solving skills making your demand in the market. Leading development companies always hire dedicated developers who have the expertise and in-depth knowledge of new technologies like Blockchain.
