When they ask me how Satoshi created Bitcoin's magic, I usually answer that #bitcoin was conceived to avoid censorship and return freedom and sovereignty.
Based on 4 existing technologies, its true magic lies in joining these technologies in something that will revolutionize the world.
The 4 gems that Satoshi used and that gave life to #bitcoin:
Public key cryptography: a system for the safe data exchange described publicly for the first time at the end of the 1970s. It allowed to sign and digitally validate the property of an information.
HASH -based safe identifiers: whose first generation was also implemented in the late 1970s. It allowed to create verifiable summaries of information.
Peer-To-Peer networks: a way to connect computers that attracted public attention at the end of the 1990s through the Napster file exchange service. That allowed to transfer from point to point, without intermediaries an information.
Proof of work: a spam deterrent described for the first time in 1997. which allowed to demand an effort (energy) to be able to send information.
Not censoring is the freedom to express yourself and access the information you choose to enter maintaining your privacy. #bitcoin
