Hey guys, I want to contribute to bitcoin core. I am an intermediate programmer and want to get started contributing fast. I have already cloned the git repository. Can you maybe direct me to sources where I can learn more about the structure of bitcoin core and specifically to problems where I can get experience working with the source code? I know Python, C/C++ and a bit of Java. I have advanced knowledge of cryptographic concepts and procedures and try to teach myself some of the math, especially around elliptic curves. I am currently composing a bachelor thesis around the question of Blockchain usage in the car-industry, where I try to look at different aspects of protocol-design. Best Regards Daniel
