I suggest visiting udemy and avail online courses about Bitcoin technical development will guide you on basics to advance knowledge so that you can catch up easily on discussion here instead of reading topics here from scratch if you want a quick learning.
I find reading topics here from scratch a faster and more efficient way to learn and understand how bitcoin works than going through several hours of courses on udemy or other platforms. Information gotten from here can also be considered to be more credible if you know how to discern what members to learn from.
Op would be better off learning how to use the search option
