Complete Roadmap to Blockchain Development
Blockchain technology is the safest way to transfer and collect information in today’s world.
And it is almost impossible for any bad guy or hacker to change, hack or cheat this system. You know what cryptocurrency is.. right?? The same technology is used in Web 3.0. Now the question is how the blockchain works.
Well, this article discusses what blockchain technology is, how it works, and how you can become a blockchain developer.
So let’s start being a blockchain developer.
What is blockchain development?
Blockchain is the chain of blocks. For example, a chain is formed by connecting one block to another block and that block to another block. It is a decentralized and distributed ledger technology that saves transactions on thousands of computers around the globe. Each blockchain contains a lot of information. For example, the blockchain of Bitcoin contains transaction information. Who gave how much bitcoin to whom is stored in the blockchain?
And it is almost impossible for any bad guy or hacker to change this information. Because each block has a unique hash.
How does blockchain work?
Suppose a hacker changed the information in block number two. When the data of block number two is changed, the hash of this block does not match the hash of the front block, i.e. the third block.
If the hacker changes the hash of the second block in the third block then the hash of the third block in the fourth block will not match. Thus the whole chain is connected. And it is almost impossible to hack this whole chain. Because this work has to be done very fast. But it takes 10 minutes to create and change a block on the Bitcoin network. This is why the Bitcoin network is so secure.
Satoshi Nakamoto added the P2P system to make this method more secure. Anyone can join this network. Each miner has a copy of the full blockchain and will update the blockchain along with the other miners. When a new transaction is completed, it will be automatically updated in the blockchain of all worldwide computers.
There are millions of miners around the world. It is impossible to update all the blocks at once and replace them in the blockchain of all the miners ones. Not just bitcoin or cryptocurrency, this method can play an important role in data transactions or storage.
In 2013, Vitalik Buterin, a Russian-Canadian programmer and co-founder of Bitcoin Magazine, came up with the idea of a distributed computing platform for smart contracts and developed Ethereum. A “smart contract” is simply a piece of code that is running on Ethereum. It’s called a “contract” because code that runs on Ethereum can control valuable things like ETH or other digital assets. Many more types of work can be done using blockchain technology. Nowadays blockchain has become very popular in the field of network security and data transfer.
There are two types of blockchain developers
- DApp Developers: These are the developers who work on an existing blockchain to create decentralized applications (DApp).
- Core Blockchain Developers: These are the developers who work on creating a blockchain from scratch. This is tougher than DApp.
In this article, we are gonna talk about DApp blockchain development.
Learn web development!
You are gonna need to learn web development in blockchain development. Your ability to work with your chosen programming languages is essential, but you will also need to learn other skills if you want to put yourself ahead of the pack and land your blockchain developer job.

Learn blockchain programming languages
Every blockchain has a different programming language that is used to make smart contracts on that blockchain. Smart contracts are simply programs stored on a blockchain that run when predetermined conditions are met. For example, smart contracts transfer ownership of an apartment once a certain amount of resources have been transferred to the seller’s account (or wallet).

Which programming language to learn?
As we have already discussed you need to learn different programming languages to work on different blockchains. Now, let’s take a look at what languages you need to learn.
For Ethereum Blockchain
To work on Ethereum or Binance blockchain you need to learn Solidity. You can find many tutorials for it online.
For Solana Blockchain
As blockchains don’t work on the same programming languages, to work on the Solana blockchain, you need to learn Rust.
Other things you need to learn
Truffle or Remix: For a suitable development environment.
Ganache: It creates a blockchain environment in your local computer, provides you with numerous addresses, and provides you with free Ethereum (Just for testing). You can test your smart contracts here.
Web3.js: Once you have successfully created the frontend website or App, you have to connect it to blockchain or smart contracts using the Web3.js library.
Metamask/Phantom: Metamask is a cryptocurrency wallet that is used to interact with the Ethereum blockchain. Simultaneously, Phantom for Solana.
Let’s Conclude
Blockchain builds trust because it presents a shared record of truth. Data that everyone can trust will help empower other new technologies that dramatically increase efficiency, transparency, and confidence.
