React Native Blockchain Dapp Development Series 4 (Basic Introduction)
cosart
Learn the basics of React Native to build your own apps or dApps that can later connect to the blockchain.
초급
Blockchain, React Native, DApp
Ngay cả công chúng cũng có thể hiểu thuật ngữ và cấu trúc bên trong của blockchain, cốt lõi của Cách mạng Công nghiệp lần thứ 4, bằng cách nhìn vào mã nguồn.

(Phỏng vấn thực tế)
1) Đào coin thực chất là gì? Đó là giải các câu đố để nhận Bitcoin (X). Thay vì câu trả lời này, đào coin giống như bên dưới, trong đó mỗi nút cạnh tranh để tìm giá trị băm (giá trị khóa) của khối, và số "000........." phía trước giá trị băm được tìm ra càng nhanh càng tốt tùy theo độ khó. -> Tôi sẽ chỉ cho bạn quy trình đào coin thực tế thông qua mã hóa.
2) Hiểu các thành phần của ví blockchain, bao gồm ví và ví giao dịch, khóa riêng tư và khóa công khai, giao dịch do ví tạo ra và UTXO.
Xin chào. Tôi có hơn 10 năm kinh nghiệm trong lĩnh vực thiết kế và phát triển phần mềm. Tôi bắt đầu chủ yếu với lập trình Java, sau đó chuyển sang phát triển di động (Android), game Unity, và gần đây nhất là các dự án Python (Django). Từ năm 2017, tôi đã quan tâm đến Bitcoin và blockchain, và tôi đã nghiên cứu về nó. Tôi tin rằng blockchain sẽ sớm trở thành trung tâm của thế giới. Cảm ơn bạn.

You explained it kindly with easy examples. I wish the lecturer's voice had been a little more powerful.
Yes, thank you. Since there is no exact explanation of blockchain concepts through coding, I coded it myself, so other parts were a bit lacking. I think it is most important to accurately understand the core points of blockchain such as mining, utxo, and wallet through coding. Enjoy coding~~ Thank you for the course review~

I keep getting errors even though I follow the programming language for creating a block chain 1234 in eclipse. When I run it, the following message appears. ㅜㅜ Exception in thread "main"java.lang.Error: unresoved compilation problem: at BlckChain/BlocChainTest.main(BlockChainTest.java:13)
Hello hsjsea6984~ Please tell me the source file or lecture location where the error occurs. Usually, you write it in the question section while watching the lecture, but I don't know the location because you wrote it in the course review. And the error you sent seems to be a problem with compilation. If you tell me the contents of BlckChain/BlocChainTest.main(BlockChainTest.java:13) I will look for it quickly. Thank you~

It helped me a lot to understand the concept of blockchain.. Thank you... I wish there was a video on how to actually apply blockchain...^^ With a simple web...^^

It was a good lecture to understand the overall blockchain structure. However, there were some parts that were difficult to check by lecture because it was difficult to check the entire code. There are parts that can be understood through code after completing all the lectures up to the final lecture, so it would be a little better if the base was written first and the main was written. Also, it was a shame that many errors in the part of making the lecture were exposed in the recording. However, it was a very helpful lecture overall, and thanks to the instructor, there were many parts that were easy to understand the blockchain structure. Thank you.
Hello dcq306. First of all, thank you for leaving such a long review. I bought Bitcoin and learned the essence of blockchain. The reason is that I invested a little of my own money at that time --; To conclude, I plan to update this lecture within June. I will also increase the lecture price. The goal is to make it so that you can really understand blockchain with code. Those who have already taken this lecture will recognize that you are an elite blockchainer who yearns for the structure of blockchain. The reason is that you paid for my lecture. Please wait a little. Please. I will make it so that you will not be disappointed. Since this is my first time making this lecture, it was honestly lacking. So I feel a little sorry for the people who are taking this lecture. The reason is that, as you said, the editing and content were lacking. However, the content itself is not difficult to understand the current blockchain. I think that you have to understand utxo, transaction, and mining through coding, and that you absolutely cannot understand it through words like ordinary people. Because you don't understand that, you still don't know the value of Bitcoin. They have no way of knowing why it costs 70 million won now. Now, many blockchain companies are emerging, and they are confusing themselves in interview questions Even in the interview room. What is Clay? Isn't it a copy of Ethereum? What is Ethereum? Isn't it a copy of Bitcoin with smart contracts added? What is Bitcoin? I will try to cover that in my lecture. Thank you.
