Solidity programming language

Before qualifying to be a Web3 developer, you must have in-depth knowledge and skills in the Solidity programming language. Solidity is the high-level programming language for developing smart contracts on the Ethereum blockchain. You will need to take courses in this language and also do plenty of practice to learn how to implement the knowledge acquired from the courses. 

Blockchain technology

To become a Web3 developer, you must be familiar with blockchain technology. For those who may not know, a blockchain is a digital ledger that records transactions across a network of computers. With web3 development, your emphasis should be learning how the Ethereum blockchain works since most Web3 platforms are built on the Ethereum blockchain.

dApps

dApps are software applications that run on a decentralized blockchain platform. These apps utilize the security, transparency, and immutability of the blockchain to provide users with a peer-to-peer network that eliminates the need for intermediaries. Web3 developers need in-depth knowledge about dApps, including how they work and how to develop them. 

Smart contracts

Smart contracts are self-executing contracts written as software programs running on a blockchain platform. As a Web3 developer, you must learn how to write smart contracts for various use cases on the blockchain network. 

Read our extensive blog to enhance your understanding and start developing on the Ethereum network.

Steps to becoming a Web3 developer

In this section, we will share with you a step-by-step process you will have to go through to become a Web3 developer; 

Step 1: Learn Solidity programming

As mentioned earlier in this article, the Solidity programming language is the primary language used to write code for smart contracts on the Ethereum blockchain. When learning this language, these are some of the areas you need to give your absolute focus. 

Solidity basics and syntax

As a beginner, you need first to understand the basics and syntax of this language. The syntax of Solidity is similar to that of C++, and it supports object-oriented programming concepts like inheritance, polymorphism, and encapsulation. You will also need to learn the basics of Solidity, including contracts, functions, variables, data types, and more. 

Writing and deploying smart contracts

After writing smart contracts using Solidity, you need to learn how to deploy them on any given blockchain network. This process includes testing the smart contract code with tools like Truffle or Ganache to simulate their execution and check for errors or bugs. To deploy smart contracts, you will use a blockchain network like the Ethereum mainnet. 

Interacting with smart contracts

Finally, you must know how to interact with the smart contracts deployed on a blockchain network. This will help you get the final users’ perspective. Interacting with smart contracts involves sending transactions to the contract’s address on the blockchain network using a Web3-enabled wallet such as MetaMask or Rainbow. 

Step 2: Understand blockchain technology

Web3 developers need to have an in-depth understanding of blockchain technology and how it works. Also, read about decentralized finance (DeFi) and have all your doubts cleared.

What is blockchain?

A blockchain refers to a decentralized distributed digital ledger that records transactions across a network of computers. The data stored in each block includes a cryptographic hash of the previous block, a timestamp, and transaction data. Individuals or groups called miners own computers used to validate transactions on any given blockchain network. 

How does the blockchain work?

In contrast to centralized platforms, a network of computers stores blockchain data. When a transaction happens, the system broadcasts it to the network. The nodes then employ consensus algorithms to verify and validate the transaction. After all the nodes confirm the transaction, they add it to a new block alongside other transactions. Finally, they link this new block to the previous blocks on the network. This leads to a series of linked blocks, hence the name blockchain.

As we mentioned earlier, each block on the blockchain contains a cryptographic hash of the previous block, making it tamper-proof and immutable. This feature is one of the reasons why the blockchain has a transparent and secure record of all the transactions that have taken place on the network.

It should also be noted that the blockchain is decentralized, so there is no need for intermediaries to verify and process transactions, making it faster, cheaper, and more efficient than traditional systems.

Types of blockchains

There are three major types of blockchains, including the public blockchain, private blockchain, and consortium blockchain. Let’s explain each of these in detail; 

-Public Blockchains: These are decentralized blockchain networks allowing anyone to join and participate. Transactions on public blockchains are verified and recorded by a consensus mechanism, such as proof of work or proof of stake. Common examples of public blockchains include the Bitcoin, Ethereum, and Litecoin blockchains.

-Private Blockchains: These are closed blockchain networks that only allow authorized parties to participate. The transactions on private blockchains are verified and recorded by a centralized authority. Some common examples of private blockchains include R3 Corda and Ripple.

-Consortium Blockchains: These have features of both public and private blockchains. With consortium blockchains, a group of organizations comes together to form a network, and each has equal control over the consensus mechanism and validation of transactions. Common examples of consortium blockchains include Enterprise Ethereum Alliance (EEA), Hyperledger Fabric, and Quorum. 

Ethereum blockchain and its importance in Web3

The Ethereum blockchain is among the first and most popular blockchain networks, which is why every Web3 developer needs to be familiar with it. The good news is that the Ethereum blockchain is open source, so any developer can use it without the need to pay a fee or have special access. 

Step 3: Study dApps

As a Web3 developer, you must have in-depth knowledge of dApps and how they work. Let’s share some more details about dApps.

What are dApps?

There are software applications built to run on a blockchain network. Most of the popular apps we use on our phones and computers run on centralized servers. However, dApps are built on top of a distributed ledger, enabling them to be more transparent, secure, and resistant to censorship.

dApps are usually open-source, allowing the general public to view and audit their code. They are also designed to be self-governed using smart contracts, so they don’t need a central authority to operate them. 

How dApps work

When a user interacts with the UI of a dApp, their actions are recorded on the blockchain, and the smart contract is executed automatically based on the rules and protocols of that specific contract. Since they are decentralized, there is no need for intermediaries like banks or other financial institutions to verify and process transactions. This eliminates the bureaucracy and hefty transactions of intermediaries, making transactions on dApps much faster, cheaper, and more efficient than traditional applications.

Popular dApps and their use cases

The Ethereum network alone has over 2700 dApps. Some of the most popular ones include the following; 

-Uniswap: This is one of the most decentralized exchanges that allow you to trade cryptocurrencies without intermediaries.

-Compound: It is a lending and borrowing platform that you can use to earn interest on your cryptocurrency holdings or borrow funds using any digital asset as collateral.

-CryptoKitties: It is a game that allows you to collect, breed, and trade digital cats on the Ethereum blockchain.

 -Augur: This is a decentralized prediction market that allows you to bet on the outcome of events, such as elections or sports matches.

-Brave: This is a web browser that rewards users for viewing ads. The rewards are paid using its cryptocurrency, Basic Attention Token (BAT).

Step 4: Practice with real-world projects

Like any other technical skill, becoming an excellent Web3 developer requires plenty of practice. Here are the basic things you need to focus on during your practice. 

Building a simple dApp

After learning the basics of building dApps, you should start developing simple dApps, such as decentralized games. This will allow you to master the basics and the entire process of creating these apps and deploying them on a blockchain network. 

Creating and deploying smart contracts

Smart contracts are a crucial part of any Web3 platform. So, you will likely encounter them on almost every Web3 development project. As mentioned earlier, you will need knowledge and skills in Solidity programming language to create smart contracts. 

Participating in hackathons and coding challenges

Being part of hackathons and coding challenges is one of the proven ways to master Web3 skills. Most of these coding challenges and hackathons offer prize money to winners. However, besides the prize money, you will learn a lot about Web3 even if you don’t win.
