Very often in various online discussions, people cite the word "cash" from the Bitcoin whitepaper title as evidence that Bitcoin should be used for everyday transactions.

I've seen mentions that the term "Electronic Cash" as it appears in the whitepaper title has a very specific meaning in the cypherpunk/computer science community. I've tried looking for a definition online, but I couldn't readily find a more elaborate definition of the term.

What is the meaning of "Electronic Cash" in the computer science lingo?
