 This project is meant to learn and understand Bitcoin and Blockchain. I personally also in the process of learning. So, what's a better the approach of learning it by building one ! Because of this is a continuous learning process, there might be something I do not understand earlier. Now when I understand it, the code will also be changed according. I am happy to discuss with you, which will make this learning process quicker and efficient.
