This is a compilation of everything you need to know about Web3 development, and the information has been compressed into a single page. Here, you can learn and be guided through all the steps involved in the development process (processes like deploying smart contracts, Dapps, and so much more). This tutorial is designed to assist individuals from all backgrounds, from individuals with zero coding experience to senior web developers.
Career Pathways in Web3 Development
As a Web3 developer, you have many career paths to embark on. These careers include being a frontend developer, full-stack developer, solidity developer, competent contract developer, blockchain, architecture, protocol developer, etc. The amount web3 developers get paid ranges from $60k to over $1 million, depending on an individual’s skill and experience.
Listed below are a few Web3 jobs and the yearly payment:
- Senior solidity developer – $100,000 – $170,000 annually
- Go engineer – $80,000 – $90,000 annually
- Lead frontend developer – $130,000 – $200,000 annually
Understanding the technology of blockchain is key for a web3 developer.
Blockchain is a shared database that is distinctive from traditional data storage databases. The name “blockchain” implies that information is stored in “blocks,” which are then linked together through cryptography. In as much as various kinds of information can be stored on a blockchain, what it has been frequently used for is as a ledger for records and transactions.
For instance, when dealing with cryptocurrencies, blockchain is usually used in a decentralised manner, preventing a user or group of users from retaining absolute control but ensuring that all users simultaneously hold on to their control. If this needs to be clarified, try taking a course on blockchain technology. There are a lot of relevant courses available on Udemy
What Does Dapp Mean?
Dapp is an abbreviation that means decentralised application. They are the applications that are built on top of blockchains. Generally, Dapps are made up of two parts:
- A normal front end is designed using traditional tools like JavaScript and HTML (which includes libraries/frameworks like React, svelte, and the like).
- A Solidity/ Rust backend, this part is what differentiates the application as a Dapp. When you’re building a blockchain, this backend interacts with it.
How to Get Started with Frontend Development
Most times, it is difficult to differentiate between the good courses and the bad ones even after searching through Google for frontend courses, so we have taken the liberty of finding the best courses on the web for you:
- Freecodecamp is the best place to start your frontend developer journey, as there are multiple web design courses and over 300 free courses to learn from.
- W3Schools offers a free step-by-step guide to learning JavaScript and other languages.
However, when building an entirely functional front end, you can make use of vanilla JavaScript. Its scalability is lesser, but it doesn’t bring those ready-to-use tools that libraries and frameworks provide, which include React, Svelte, and Vue.js.
Do You Need Backend Development to be a Web3 Developer?
If you must be involved with smart contracts, you must understand and become one with the concept of backend development. You must select a blockchain on the backend and continue with a single language. When you have finally figured out the architectural shift, you can go on ahead to start thinking more about your efficiency, how to manage storage and those things that influence you to be an excellent smart contract developer.
Although, if you want to be involved with frontend development, then this is not compulsory. If you are looking to work in blockchain and be among the builders of what the foundations web3 is made of, being a master of backend development is totally necessary. As a person with zero knowledge about the backend, you may find this hard to break into because the littlest mistakes made while coding in the backend have cost both big and small companies a tremendous amount of money.
It is most importance to note that there is a massive difference between decentralised applications backends and web backends. Unlike regular backends, which use databases like Postgresql, blockchain is usually the source of decentralised data storage. Most of the technical principles are still the same; that’s why we advise that you become a pro in standard backend development before proceeding into learning Web3 backend development.
What is the Meaning of Ethereum (ETH)?
Ethereum is a decentralised blockchain platform with smart contract proficiency. The native currency of this platform is ETH which originates from the fictional element. The originator of this platform is a Russian-Canadian programmer known as Vitalik Buterin 2013. Presently, Ethereum is the largest hub of decentralized applications and smart contracts worldwide. How do Smart Contracts Work?
Smart contracts are programs that run on the blockchain when standards that have already been estimated are met; they are usually self-executing. When smart contracts are used, the performance of a deal is immediately automated; with this, users can know the outcome fast without any waste of time or the participation of a third party.
Trading, lending, investing, and borrowing are all examples of financial applications, and they are a few of the many uses of smart contracts. They can also be used in games, real estate, healthcare, and even in building company structures.
Smart Contracts Tests
Writing a smart contract test is essential for any blockchain application’s security and effectiveness. We can always use integration and unit tests to test the internal logic of smart contracts. Unit tests can be written to confirm function return values and to state different values, and integration tests can examine the interactions between contracts. These tests are written to ensure that the inheritance and dependency injection processes function perfectly.
Conclusion
There is no limit to what you can do with smart contracts. As technology develops, the usefulness of smart contracts comes to light in the Web3 world. I wish you all the luck you’ll ever need in your development journey.
