Why Blockchain?

As we have seen, there is absolutely no central control, no national boundary, and no specific owner in Blockchain. Its security is powered by sophisticated cryptographic processes performed by p2p users, through a process known as mining.

Here are some of the reasons why we need to embrace Blockchain technology.



It is impossible for anyone to tamper with transactions or ledger records present in Blockchain.

Worldwide Adaptation

Blockchain has been adopted worldwide and has the backing of many investors from both the banking and non-banking sectors.

Blockchain masters program

Automated Operations

In Blockchain networks, operations are fully automated through software implications. Private companies are not needed to oversee the operations.

Open-source Technology

Blockchain happens to be an open-source technology. All operations within a Blockchain network are carried out by the open-source community.

Distributed Architecture

Blockchain works in a distributed mode in which records are stored in all nodes in the network. If one node goes down, it doesn’t impact the other nodes or records.


The Blockchain network can be programmed using the basic programming concepts. This flexibility makes Blockchain networks easy to operate on.

Learn What Blockchain Can Do

Blockchain is a digital ledger that keeps a record of all transactions taking place in a peer-to-peer network. All information transferred via Blockchain is encrypted and every occurrence is recorded, meaning that the information cannot be altered. As a decentralized network, Blockchain networks do not require any central or certifying authority. For this reason, these networks can be relied upon for much more than the transfer of currency; in fact, contracts, records, and other kinds of data can be shared across the Blockchain network. Encrypted information can be shared across multiple providers without risking a privacy breach.

Blockchain has gained immense popularity, because of these attributes:

  • Blockchain networks are distributed ledgers on the Internet
  • Each action is visible for everyone; only adding lines is possible and that too after consensus
  • ‘Peer to peer’: No third party is required in order to carry out transactions
  • Secured by unbreakable cryptographic hashing


Individuals including software professionals and graduates who want to build a career around the Blockchain network or those who want to learn the precepts of Blockchain as a whole are most welcome to this Intellipaat Blockchain tutorial.


  • Familiarity with scripting languages such as HTML, JavaScript, and CSS
  • Enthusiasm to grow with the fast-paced evolution of Blockchain

Frequently Asked Questions

What programming language is used for Blockchain?

Blockchain-based projects support several programming languages including Solidity, C#, C++, SQL, Ruby, Java, JavaScript, Python, and GoLang. However, Solidity is majorly used.

How Blockchain works step by step?

Whenever a blockchain is introduced to a new blockchain transaction or any new block is to be added to the blockchain, in general, numerous nodes within the same blockchain implementation are required to execute algorithms to evaluate, verify and process the history of the blockchain block. If most of the nodes authenticate the history and signature of the block, the new block of blockchain transaction is accepted into the ledger and the new block containing data is added to the blockchain.

How do I get started with Blockchain?

To get started with blockchain, you can understand Merkle and hash trees. This tutorial covers the basics of blockchain in a comprehensive manner. We also have a YouTube video on Blockchain tutorial that can help you enhance your understanding of the subject.

What is Blockchain in simple words?

In simple terms, the Blockchain ledger is digital, distributed and decentralized. As the name suggests, blockchain is nothing but a linear chain of blocks that holds information of transactions taking place over the web. Every block contains data in the form of coding that is organized in a chronological manner.

Can blockchain be hacked?

Blockchain networks are undoubtedly the most secure form of technology we have presently, but it won’t be far from now when some hacker will eventually find his/her way through our so-called secured blockchain. A lot of research is being done to curb the broken ends that exist in the blockchain world today.

Does blockchain require coding?

Coding is a necessity for blockchain developers. One cannot develop secure blockchain applications without knowing how to code.
