### Translations
<A href="https://www.amazon.cn/%E5%9B%BE%E4%B9%A6/dp/B01KGYHBEM/">Chinese</a> and <a href="https://www.amazon.co.jp/dp/4822285456/">Japanese</a> versions of the book are available. A Korean version is in preparation.
### Free pre-publication draft
A pre-publication draft of the book is available for download <a href="https://d28rh4a8wq0iu5.cloudfront.net/bitcointech/readings/princeton_bitcoin_book.pdf">here</a>. The published version is better in a several ways: it is peer-reviewed, professionally edited and typeset.
### Coursera course
The Coursera course <A href="https://www.coursera.org/learn/cryptocurrency">Bitcoin and Cryptocurrency Technologies</a> is a useful complement to this textbook. It has a series of video lectures that closely follow the textbook content, plus programming assignments and quizzes.
### Programming assignments
There are three programming assignments which will take you through the steps of designing and building a basic cryptocurrency. The programming language we use for the assignments is Java. This is not because we're fans of Java, but because the infrastructure we used for creating grading scripts is Java-based.

</div>
<br></br>
The zip file contains three folders. In each folder, the assignment specification is provided as a PDF file. You're also provided starter code in the form of .java files.
We've used these assignment in courses that we've taught, but there may still be bugs in them. We appreciate your understanding and would be grateful for any bug reports. Email us at [bitcoinbook@lists.cs.princeton.edu](mailto:bitcoinbook@lists.cs.princeton.edu).
<br>
We also have grading scripts for each of these assignments. If you're an instructor and would like access to the grading scripts, please send us a brief email in which you introduce yourself and tell us about your course.
