haha, i want to learn bitcoin core code, but cannot find some concrete or detailed material about module(eg, how does P2P work in Bitcoin Core)or data structure(eg, CBlockIndex, CMempool)
I just wonder if there is any material about Bitcoin core code for references.
Will you please share your thoughts here

Yes it is really hard to find it of course! But if we want to have that maybe, just maybe there are many ways hm. what do you think? Is it possible to find detailed material about bitcoin?
