随着区块链技术的普及和推广，区块链应用如雨后春笋般涌现，有很多好的区块链应用正在影响和改变我们的生产、生活方式。本报告首先介绍了现有信息系统在安全和隐私保护领域里的相关技术，然后从区块链的五层技术架构的角度逐层分析信息安全与隐私保护的相关技术原理，并解释和说明了如何构建安全可靠的区块链应用系统，最后结合量子密码学技术，探讨其对区块链隐私和安全构成的威胁，以及展望抗量子密码技术发展的必要性。
With the popularity and promotion of blockchain technology，blockchain applications have sprung up like mushrooms，and there are many good blockchain applications that are affecting and changing the way we produce and live. This report first introduces the related technology of the existing information system in the field of security and privacy protection，and then analyzes the relevant technical principles of information security and privacy protection layer by layer from the perspective of the five-layer technology architecture of the blockchain，and explains how to construct a secure and reliable blockchain application system. Finally，combined with quantum cryptography technology，the threat to the privacy and security of blockchain is discussed，and the necessity of anti-quantum cryptography technology development is prospected.
