Should we start with the Caesar cipher and the conch shell? This question is too broad.

@RedGrittyBrick I learned Ceasar cipher in school :-) .Note the words "outline" and "main" in the question. These words should keep the answer narrower.

Bitcoin is roughly defined by the 2009 [whitepaper](https://bitcoin.org/bitcoin.pdf). Long before, the idea of a trustless cryptographic money was discussed by [Wei Dai](http://www.weidai.com/bmoney.txt); however, Wei Dai couldn't solve the double spend problem, which delayed the creation of magic crypto money until 2008 (yes, the Satoshi client was created before the whitepaper)
