Bitcoin, Ethereum, cryptocurrency, and blockchain are popular terms floating around the Web and taking the world economy by storm. Revolutionizing commercial transactions all over, cryptocurrencies are one of THE most disruptive technologies of this century, and blockchain development leis at the heart of it all. Yet, governments and financial institutions are resisting widespread implementations with all their power, just as the number of cryptocurrency exchanges and blockchain applications rises all over.

So, what is all the fuss about? What is blockchain? How is it developed and implemented? And, why has it got innovators excited and established financial institutions, even governments, trembling in their shoes?

The answer to all such questions lies ahead.

What Is Blockchain? Features and Benefits

According to popular skill development and MOOC platform, Upgrade, blockchain was one of the fastest-growing skills on the platform. The success and popularity of cryptocurrencies such as Bitcoin & Ethereum lie behind this swift rise in demand and popularity. Every industry wants in on the action now, simply because of the exceptional features and massive innovation potential. 

Here are some data that showcase the rising popularity of blockchain.

  • Global Spending on Blockchain in 2021 amounted to 6.6 billion dollars.
  • The Banking Sector has the highest distribution of blockchain’s market value.
  • The United States of America possesses 51% of the total global market value in overall blockchain funding.
  • Secure information exchange and cross-border payments & settlements are the most prominent blockchain use cases. 


Blockchain-powered cryptocurrency is growing with each passing day. From online paper help services to B2B marketplaces, blockchain finds usage across different sectors. 

So, what is blockchain?

It is a distributed database of records or a public ledger of all transactions or any digital event executed and shared among the participating parties. A blockchain system contains specific and verified descriptions of every single transaction ever made using the system.  The primary hypothesis of blockchain technology is that the system creates a distributed consensus digitally. Participants of the system would have a definite & irrefutable record of everything in a ledger, accessible to those with authority or the common public. It is this decentralized nature that is disrupting businesses and transactions the world over, sparking innovation and challenging legacy systems.

Features and Attributes 

Understanding the potency of blockchain requires a proper understanding of fundamental properties and the manner of its working.

Blockchain is made up of a chain of time-stamped blocks, each containing a record of some data and managed by a cluster of computer nodes, not any single authority in particular. Cryptography plays a central role in blockchain, and every block is secured & linked with each other using cryptographic principles. 

Blocks – A block is akin to a page in a ledger. Every block contains a time-stamp, some data, its hash, and the previous block’s hash. 

The data saved in a particular block depends on the application specifics of the blockchain system. 

Hashes – Hashes act as the security in a blockchain system.  Cryptographic hash functions take an arbitrary input and produce a unique value, which lends each block its own unique identity. Hashes are the fingerprints of every block, and every transaction in a block has its hash.

The hash of a previous block can be added to a new block to ensure validity and chronology. In addition, the time-stamps of each block help keep track of the time of a block’s creation.

Cryptography and Consensus Protocols – Security and decentralization are two critical attributes behind the immense demand for blockchain. Cryptography and consensus algorithms ensure optimum security and perfect decentralization. 



Next up, let’s take a look at some of the most in-demand blockchain development tools of 2021.

Top Blockchain Development Tools

Developing a blockchain network infrastructure takes strong & comprehensive knowledge about programming, networking & data security, IT, and cryptography. Alongside the above skills and years of hard work, solid ideas about different tools for blockchain development are necessary to become a capable blockchain developer. 

Here are some of the top blockchain development tools in 2021.10.9

1. Solidity

Solidity is currently the most popular programming languages cum platform development environment used by Blockchain developers across various application domains. 

Solidity supports the Object-Oriented Programming paradigm, making it helpful in developing blockchain applications that run self-enforcing business logic. Applications range from creating smart contracts, voting, crowdfunding, multi-signature wallets, and blind auctions.

2. Geth or Go Ethereum 

Geth is a widespread implementation of an Ethereum computation node using the Go programming language. Available in three variations, Geth finds numerous uses on the Ethereum blockchain, such as token transferring, smart contract creation, and exploration of blockchain. 

Geth allows developers to create their own blockchain network easily by connecting with the main Ethereum network seamlessly.


SOLC or the Solidity Compiler is a command-line compiler written using C++. It is an effective tool and helps transform Solidity scripts into more readable formats for the Ethereum Virtual Machine. SOLC comes bundled with most Ethereum nodes (that is, nodes running Geth) and can be used for offline compiling.

4. Remix

The Remix IDE is a blockchain tool that runs on browsers as well. Browser-based operations are its most significant benefit, and Remix is a popular tool for developing and deploying smart contracts. 

Remix is written in JavaScript and can be implemented n any modern browser. Thus, it can be used for coding, testing, debugging, and deploying blockchain contracts in Solidarity. 

5. Blockchain Testnet

The importance of the Blockchain Testnet in the world of blockchain development can never be stressed enough.  

A Blockchain Testnet allows developers to test their dApps (decentralized applications) before deploying them live. Every blockchain solution (private, public, consortium, and hybrid) has its own unique Testnet. Testnets are extremely useful as they allow for the testing of dApps for bugs and glitches.

6. Truffle

Truffle is a developmental framework for blockchain and Ethereum. The platform allows for testing Ethereum-based decentralized applications. In addition, it offers an extensive library of customized deployment & resources for developing smart contracts and several other aspects of blockchain development.

Truffle allows developers to inject blockchain contracts into web applications as well as develop front-end dApps. In addition, the framework will enable developers to run automated tests of apps & systems written in JavaScript, TypeScript, and Solidity. 

7. Ganache 

Ganache is a component of the Truffle suite and helps developers to test their apps before deployment carefully. 

Ganache is a famous blockchain development tool that employs a machine’s local memory for development and testing. The local Ethereum Blockchain created by Ganache simulates all the features of its traditional counterpart.

Ganache enables users to get complete control of the test blockchain using block explorer, advanced mining, and blockchain log.  And the most significant benefit stems from the fact that developers do all such stuff without incurring Ethereum’s gas fees.

And that rounds up this article. Blockchain will bring about further disruptions and transformations to different sectors in the years to come. What we are witnessing is just the beginning!
