BApp Development for Everyone - Introduction to EVM Blockchain for Everyone

💡 Vividly learn the basic knowledge you need to know

This course was designed to serve as a training platform for my next blockchain course. Therefore, I'll provide essential, fundamental knowledge through hands-on practice.

💡 Easy and clear explanation of concepts

This isn't a lecture that delves into difficult or complex concepts or theories, but rather a quick, no-frills course. However, it does provide a clear explanation of the essential concepts, including their reasons for existence.

💡 Check before taking the class

We'll provide access to the first half of the course (preview), course materials , and even source code . We encourage you to attend the lectures yourself to determine if they're right for you.

Q. I followed the lecture well, but why isn't it working for me?

Even if you follow the lectures closely, because they rely on external services like Klaytn Network, Metamask, and Opensea, there are times when the lectures will simply not work the next day for no reason. Changes in these external services may also require lecture updates. Please feel free to ask questions and we'll be happy to help.

Q. Am I the only one who doesn't quite understand the lecture?

Comprehension may vary depending on the student's level of knowledge. We recommend watching the lecture at least twice. The first time, simply watch the video while commuting to and from work. The second time, we recommend reading through the material while practicing together. Feel free to ask questions about anything you don't understand.

Q. Is there a reason I should know about blockchain technology?

Let's take a database as an example. If a database is useful and widely used, we should learn it. I think it's a good idea to learn at least simple CRUD operations in advance for the future. (CRUD stands for Create, Read, Update, Delete. It's the basic unit of data manipulation in a database.)

Q. I want to know the basic concepts of blockchain and the basic grammar of Solidity.

There are already great lectures on how to gain this knowledge, so I'll share the link.

• This course will be conducted on Windows. However, you can also easily follow the course on other operating systems, such as macOS and Linux, by simply installing VSCode and Node.js.
• We provide source code and lecture materials . We recommend that you first preview the lecture and then use the materials to make your own judgment.
• Programmers taking this course for the purpose of blockchain development should know basic JavaScript and TypeScript syntax to accurately understand the code.
• For those in other professions, not programmers, I don't think it's important unless they need to understand the code precisely for work, but if you're interested after taking the course, it would be good to understand the basic grammar of JavaScript and TypeScript.
• Recommended way to take the course: First, watch the lectures only in video format during your free time, such as during your commute. Then, from the second session onwards, try to follow along with the exercises.
