I read this book when I took CS251 last fall. It is an accessible, mostly nontechnical overview of Bitcoin and cryptocurrencies. For those interested in reading the book and learning more about cryptocurrencies, I recommend going through the CS251 reading list which includes this book.<p><a href="https:&#x2F;&#x2F;crypto.stanford.edu&#x2F;cs251&#x2F;syllabus.html" rel="nofollow">https:&#x2F;&#x2F;crypto.stanford.edu&#x2F;cs251&#x2F;syllabus.html</a>
