This repository hosts an open-source book, written in Chinese, that explains blockchain technology from its basic concepts through to practical applications. The book is primarily aimed at readers who have some background in financial technology or distributed systems and want to understand how blockchains work, but the author notes that even readers without a technical background can use it to get a general picture of the field. The book covers how blockchains originated, what distinguishes them from ordinary databases, and why they are considered relevant to finance, supply chain, and other industries. It then walks through how Bitcoin and Ethereum work, covering the mechanics of how transactions are verified and recorded without a central authority. A substantial portion focuses on Hyperledger Fabric, an enterprise-grade blockchain platform designed for businesses that need controlled access and privacy, as opposed to fully public networks like Bitcoin. Reader paths are suggested based on your goal: beginners are directed to early chapters on fundamentals, Ethereum developers are guided toward the smart contract chapters, enterprise teams are pointed at the Fabric-specific sections, and architects are directed to the chapters on system design and performance. A PDF version is available for download from the GitHub Releases page for offline reading. The book is accompanied by a published print edition titled "Blockchain Principles, Design and Applications" (second edition), which has been translated into multiple languages and focuses on Hyperledger Fabric 2.x. The online version of the book is freely readable at a linked GitBook page.
