Beginner C++ blockchain project – need help with next steps and review

I am a beginner programmer and new to C++ and blockchain. I am currently trying to build a basic blockchain from scratch, using Bitcoin as a reference. I’ve made some progress, but I’m not sure I’m going in the right direction. I’m stuck and can’t decide what to implement next.

I’ve provided a link to my repository, but I was wondering if someone could review my code and let me know if this is close to a functional blockchain or if it doesn’t make sense. Any feedback would be greatly appreciated!
