In my experience, @codedamncom is an incredibly effective tool for learning how to code and building skills as a programmer and developer. They give out detailed structured curriculums along with doing some amazing projects. I notice myself becoming more productive and improving.

The reason I didn't take any free course is that this paid course is letting me keep track of my progress (I have attached a screenshot for the same). It contains the right videos for the content that I need to learn Solidity.

If you are planning to buy a course for full-stack. I would suggest go with a @codedamncom free resources. Their resources are more than enough to get started and once you feel confident then only purchase their pro package. Which is worth the money I believe. #100DaysofCode

Codedamn's courses are very resourceful, apart from the knowledge gained I'll be getting a certification at the end of the course, which will go a long way giving the fact that am a student ^_^.

I have seen so many courses but finding course that gives lecture + playground to code is difficult to find. But codedamn is totally amazing in this perspective even quality of contents is unmatchable and helped me many times in understanding full stack courses concept in depth..
As blockchain technology and cryptocurrencies continue to revolutionize various aspects of our lives, Web3 emerges as the next significant development in our online experience. Let us explore what Web3 is, why it matters, and how you can step into this exciting realm as a Web3 developer. Let's dive right in!
What is Web3?
Web3, short for Web 3.0 or the decentralized web, refers to the third generation of internet services that leverage blockchain technology. It aims to create an online environment where users are in control of their data, and applications are decentralized, meaning they aren't governed by any single entity but operate on a network of computers (nodes).
Why is Web3 Important?
The significance of Web3 is twofold:
- User Empowerment: Unlike traditional internet services where your data is stored and potentially monetized by corporations, in Web3, you control your own data. This could potentially lead to a more private and secure internet.
- Decentralization: By utilizing blockchain technology, Web3 aims to create a decentralized network where no single entity has control. This could lead to greater transparency and less censorship.
Web3 Learning Path
Now that we've covered what Web3 is and its importance, let's examine the steps to becoming a Web3 developer.
2. Learn about Blockchain and Cryptocurrencies: As the foundation of Web3, understanding how blockchain works is essential. Also, familiarize yourself with cryptocurrencies, specifically how transactions work and what smart contracts are.
3. Master Ethereum and Solidity: Ethereum is the leading platform for building decentralized applications (dApps). Solidity is the programming language used to write smart contracts on the Ethereum platform.
4. Learn Web3.js or ethers.js: These are libraries that allow your application to interact with the Ethereum blockchain.
5. Understand IPFS: The InterPlanetary File System (IPFS) is a protocol and network designed to create a content-addressable, peer-to-peer method of storing and sharing data in a distributed file system. It's a key concept in building decentralized applications.
6. Practice with Real Projects: The best way to learn is by doing. Consider building simple dApps or contributing to open source projects to hone your skills.
Frequently Asked Questions
Q1: Do I need a degree to become a Web3 developer?
A: No. While formal education in computer science can be beneficial, most Web3 skills can be acquired through self-study, online courses, and practical experience. What matters most is a strong understanding of blockchain technology, smart contracts, and the chosen development libraries.
Q2: Is it hard to become a Web3 developer?
A: Web3 development does require a deep understanding of new and complex technologies like blockchain and smart contracts. However, with a systematic learning path, diligent practice, and constant curiosity, becoming a proficient Web3 developer is definitely achievable.
Q3: What is the difference between Web2 and Web3?
A: Web2 refers to the current version of the internet, characterized by interactive, user-generated content and the growth of social media. However, it's centralized, meaning your data is controlled by a few big companies. Web3, on the other hand, is a vision for a fully decentralized internet where users control their own data.
Q4: Why is Ethereum important in Web3 development?
A: Ethereum is the leading platform for creating decentralized applications, mainly due to its smart contract functionality. It allows developers to write business logic that controls digital assets and runs exactly as programmed without any downtime, censorship, fraud, or third-party interference.
