Blog post about how Bitcoin works in a way non computer people can understand it

Bitcoin for laypeople

(Chinese version available here, courtesy of @jiangplus

(This is an English translation of my Danish blog post, Bitcoin for voksne)

Bitcoin is a digital currency that has no central authority. It's a currency where you do not have to rely on anyone to know it's worth it. As a concept, it's similar to gold. Gold has a value in itself, as opposed to, say a $100 note that only has value if the U.S. government says it has value. Similarly, the idea of ​​Bitcoins is that they have value by themselves.

{{ mkdir "build" }}
{{ copy "static/*" "build" }}
{{ render "404" | write "build/404.html" }}
