I am looking for papers which are easy to understand, papers which are for undergraduates. I often stumble upon papers which require lots of reading to do and soon I have dug into a recursive rabbit hole. I would like to know about papers which have minimal citations/dependencies and only require knowledge of CS basics.
A good example of such paper would be Bitcoin. You don’t need to be a CS wizard to understand the paper. Plus, you can ignore the math part and yet appreciate the beauty of Bitcoin.
Some other examples: Bit Torrent, TOTP RFC.
