Code Examples:

Mastering Bitcoin is a book for developers, although the first two chapters cover bitcoin at a level that is also approachable to non-programmers. Anyone with a basic understanding of technology can read the first two chapters to get a great understanding of bitcoin.

This repository contains the complete first edition, second print, published in December 2014, and the complete second edition, second print, published in July 2017, as published by O'Reilly Media in paperback and ebook formats. 本书是为开发人员写的，当前两章的关于比特币的内容对于非程序员也是可以理解的。 任何对技术有基本了解的人都可以阅读前两章来获得对比特币的基本了解。 本库包含本书的1.2版（201412月发布）和2.2版（2017年7月发布）。 https://github.com/bitcoinbook/bitcoinbook/releases/tag/Edition1Print2 https://github.com/bitcoinbook/bitcoinbook/releases/tag/second_edition_print2 由O'Reilly Media发布纸质版和电子版。

Other parties may choose to release PDFs of the book online. 阅读这本书，可以看books.asciidoc，点击每章在浏览器中阅读。 https://github.com/bitcoinbook/bitcoinbook/blob/develop/book.asciidoc 这并不像在电子阅读器上阅读PDF或电子书一样方便，因为这是有代价的（见下文）。 第2版的license是CC-BY-NC-ND，而不是CC-BY-SA。

 CC Creative Commons 知识共享  BY 署名 – 你必须以给予姓名标注，并提供本许可证的链接。同时你需要声明公开的创作是否经过修改。你可以采用恰当的形式将相关信息表述出来，但不得以任何形式暗示授权人已正式认可了你以及你的使用行为。  NC NonCommercial — You may not use the material for commercial purposes.  ND NoDerivatives — If you remix, transform, or build upon the material, you may not distribute the modified material.（如果你对材料进行重混、转换或建造，你不能分发修改后的材料。）  SA 相同方式共享 – 如果你对本创作进行了重混、转换、依据本创作进行再创作，你必须依据本创作采用的许可证来分发你的创作。 这是故意不提供PDF格式。 为什么？因为PDF是一个“衍生”产品，是受ND禁止的。 这是因为出版商（O'Reilly Media）是要盈利的，它在发行图书方面投入了大量的资源。 本书最终将（在发布的一年内）在CC-BY-SA许可证下发布，届时将允许PDF格式和翻译。 在那之前，制作PDF拷贝违反了许可证，干扰了出版商（和作者）谋生的能力。 此外，如果你这样做，出版商不能收回他们的投资，他们会推迟CC-BY-SA的发布。 在许可证更改为CC-BY-SA之前，请不要创建和分发PDF。 出版商甚至很少同意CC-BY-NC-ND许可证。 不要因为违反这个已经慷慨的许可而使自由文化变得更难。
