user84680: Could you outline the logical sequence of main ideas (concepts) that contributed to the evolution of the bitcoin protocol from the beginning
to now?

user38618: Bitcoin is roughly defined by the 2009 whitepaper. Long before, the idea of a trustless cryptographic money was discussed by Wei Dai; 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)
