Web 3.0 is the future of internet technology. And so, it is obvious that it is highly relevant to learn web3 development for anyone who wants to work in the IT sphere. The world bounces between web 2.0 and web 3.0, but the web 3.0 approach is inevitable. So, it is crucial to start learning web 3.0 right now, as there are so many resources to learn.
By reading this article, you developers can start building a foundation of the essentials of blockchain development, smart contracts, decentralization principles, and more.
What is Web 3.0
Web 3.0 is the third and the last generation of worldwide web development. Currently, we have not fully entered this era, but with every new day, there are more projects relating to web3 core concepts.
One of the main principles of the third internet era is decentralization. It means that no authority can create beneficial conditions for himself. Instead, the power is spread among users. Nobody can get into a smart contract code and change it, and such decisions can be accepted only through voting.
So let’s take a look at two main fundamentals of the web3:
Blockchain technology is used everywhere in the web3 development environment and is essential if you want to learn web3. Blockchain is a special system consisting of blocks to facilitate safe and recorded transactions.
There are a few main factors you should know when learning a blockchain technology:
- Immutable records. Each transaction is authentic and can’t be changed or manipulated after recording.
- Distributed ledger technology. Every participant of the blockchain has access to the records of transactions.
- Smart contracts. It is an automatic contract used in the blockchain, which we will discuss later.
Each transaction within a blockchain creates a unique block that stores all the important information. The blockchain platform has many blocks that deploy the transaction parties, how many assets were transferred, and more. Thus, this system can potentially answer many questions.
Each block is involved in the chain, so they are interconnected. Blockchain developers focus on security and reliability, and blocks can’t be altered or changed. Each next block system create makes the entire blockchain structure more secure and temper-evident.
Smart contracts are automated and digital alternatives to the actual contracts that we participate in real life. They are an integral part of the blockchain, managing to make transactions fast and automated. A developer writes his own smart contracts, programming them to execute actions when certain conditions are met. Smart contracts facilitate a:
- Efficient and accurate work. There is no need to complete any documents routinely. As soon as requirements are met, the contract is made.
- Reliability. The absence of a third party makes smart contracts safer than regular contracts.
- Encryption. Each smart contract features a highly-encrypted code, incredibly hard to hack.
Where to start learning the development environment of web 3.0?
Knowing the basics of web 3.0, it is time for us to build a roadmap. This roadmap will feature each critical aspect that web 3.0 developers should be familiar with. Following this list will not only help to build a better foundation but will result in an easier search for a job in the future.
Learn decentralized applications
A usual task for web 3.0 developers is to build a decentralized application, DApp. Ethereum blockchain features a unique platform to create your own DApps, showing convenience and efficiency for new developers.
Learn how to write smart contracts
Due to the broad use of blockchain, a web 3.0 developer needs to know how to create smart contracts.
To start learning, it would be a great idea to use an open-source to understand the principle of smart contract work. Then you should define the abstract token contract and store contract. Go through a few examples, and then try to write your own smart contact for a test. Create a custom developer chain to ensure that your code functions properly so you are ready to develop smart contracts further.
If it is hard for you to figure out such nuances due to your lack of experience, a smart contract course will do a job for you. It is the best way to explore smart contracts for beginners on their way to becoming full-stack developer.
Learn Ethereum blockchain and its capabilities
Ethereum is not just an owner of the famous crypto coin. It is a platform suited for developers to use its resources to develop blockchain DApps or their crypto. It is one of the best resources to learn web3 and become a blockchain developer. Many successful products are based on Ethereum, so maybe it is your time to join them. Learn Ethereum and start building your full stack DApps.
Learn the best programming languages for web3 development
Among all the languages used in web 3.0, solidity is the best one to develop smart contracts for any use. Solidity was designed to fit Ethereum Virtual Machine and will be easy to learn for Python, Java, and C++ users.
Python has become one of the most popular programming languages over the last decade. It is widely used for web development and so for web 3.0. If you are not familiar with it, you can stick to some kind of expert python tutorial to get the basics of it.
How to keep getting better at web 3.0?
It is a good question, but there are many tools that web developers can use to hone their programming skills. Some are free, like videos on YouTube, and some are for money, like full courses. But we are sure that no matter what level you are at, you will find a suitable option.
Tutorials are the reason why so many people like the internet. Elon Musk once stated that you don’t need to spend any funds to learn something in 2022. And so it works with learning web 3.0. There are plenty of tutorials on the net teaching you how to become a better developer. Some tutorials are videos, and others are just articles. Just choose what is suitable for you, and soak in knowledge.
Unlike tutorials, courses are structured lessons to provide you with some things technical for web 3.0. They deploy their information gradually and suggest you follow them for an extended time. Courses projects can be both free and paid, long and short, or it can even be something like an interactive school. Just find what works for you and keep studying.
Even an experienced blockchain developer can get something interesting out of community content. Visit forums, talk to other blockchain development experts, look at examples of their codes, and ask them questions. Such practices are incredibly helpful in the world of development.
So development in web 3.0 is a highly prospective direction of programming. No matter what your level is, it is essential to start learning components of web3 right. Make sure to follow our tutorials, use the software up to date, and don’t forget to test your codes.
