• Understanding Blockchain and Bitcoin
• Creating a Blockchain Electronic Wallet
• Creating a Blockchain Payment System
• Smart Contract Programming
• Agricultural Product Traceability Management System
• Various other projects

Is this perhaps my story ?

• “I want to know what I should study first to start developing blockchain.”
• “I want to hear an explanation that is suitable for non-specialists and does not use difficult terms.”
• “I want to learn about practical work through hands-on experience rather than theory.”
• “I want to know how blockchain technology can be integrated with other technologies, not just blockchain technology.”
• “I want to take a lecture that developers and planners can listen to together.”
• “I want to know how the DApp program works.”
• "I've been thinking about it for a long time, but I'm still confused. Can't I get a clearer understanding?"
• “It is a matter of understanding theoretically and building an actual data center to realize BM.
  “I think it will be very different. I’m curious to hear what the experts think.”
• “Not only the theory but also the contents related to blockchain and computer cryptography
  “I would like to see a deeper and broader coverage through practical training.”

• The course is structured to address over 80% of your questions and concerns. If you have any additional questions, please feel free to request one-on-one mentoring and we'll be happy to answer them.

• This lecture provided a comprehensive overview of the course, and the well-organized content, with prepared materials, streamlined the time and piqued students' interest. (Planner)
• I really enjoyed learning and practicing data processing programming, and it really inspired me to study more. (Non-major)
• Despite the short schedule, the course was packed with content, allowing me to learn the basics for the first time and get a taste of the advanced course. (Major)
• For someone like me, who wanted to pursue web and app development in connection with entrepreneurship but had no idea where to start, this course was like an oasis in the desert. (Non-major)
• I started with vague fears, but I feel a sense of accomplishment at being able to finish. I will continue to push forward, thinking of this as a new beginning, not the end. (Non-major)
• It was great to receive so much advice on my biggest concern: finding a job. I think it served as a stepping stone for me to move forward as a developer. (Major)
• I feel like I've gained a solid understanding of blockchain concepts and a practical development environment! The high quality and feedback made signing up for this course a great choice. Thank you for providing such a great course. (Major)
• This was a great opportunity to learn concretely about the principles of blockchain technology, which had previously been vague. Through hands-on training, I was able to gain exposure to a wide range of knowledge, including not only blockchain principles but also web, network, and server knowledge. This course helped me establish a direction for blockchain service development and motivated me to learn more, which I'm very grateful for. (Planner)
• Hello!! I'm so grateful for the wonderful time I had. I thought blockchain was a very difficult topic, but the instructor explained everything very kindly, step by step, and provided practical training, making it incredibly easy to understand! I only knew blockchain through vocabulary and theory (a bit), but through hands-on practice with MetaMask and Solidity, I was able to experience it firsthand! I'd like to develop my own thinking based on what I learned this time! I'm also incredibly grateful for the mentoring. As a job seeker, I haven't had the opportunity to hear from professionals, but listening to your lectures was incredibly helpful in finding my direction! You were incredibly kind, and the content was excellent. If another training opportunity arises, I'd love to participate again. (Major)

This course consists of 20% theory and 80% practice .

Q. Who is this course for?

This blockchain course is designed for a variety of people, including planners who want to plan a blockchain and create a business model, aspiring developers who are not majors but want to create dApps with blockchain technology, developers who majored in computer science but are interested in blockchain technology and want to develop in this field, people who need on-the-job consulting to create a blockchain business, and developers who are beginners in development but want to grow their skills through this course.

Q. What is the difference between blockchain and Bitcoin?

Blockchain is the underlying technology, and Bitcoin is the application. When you boot up your smartphone, the Android operating system starts running, and after booting, you'll see countless installed apps. The blockchain-based technology is like the operating system for your smartphone, and like countless other apps, there's a Bitcoin app.

Q. It seems like the only application of blockchain is coins?

The core technology of blockchain is the database. The difference between traditional databases and blockchain databases is that blockchain databases only allow data to be read and written. Once stored, data cannot be modified or deleted. Many applications can be developed by taking this characteristic into account. Voting systems and student performance management systems are prime examples. Bitcoin is just the tip of the iceberg among countless other applications. We'll discuss other potential applications in the lecture.

Q. What do I need to study to create a blockchain dApp?

These technologies include computer cryptography, computer networks, and web services. While it's helpful to understand all of these technologies to build blockchain services, their depth requires a team, not just one individual. This lecture will provide a detailed explanation of each technology.
