课程名称：密码学与哈希概述 概述：本课程将深入探讨区块链技术的性质，专注于所有权的概念，以及区块链如何处理去中心化交易。课程还将揭示密码学和哈希的重要性，这些技术对于用户身份验证和交易隐私保障至关重要。完成课程作业需要购买以下两本书： 1. Drescher, D. (2017)。 《区块链基础：25步非技术性入门》。ISBN-13：978-1484226032 2. Antonoupoulos, A. M. (2017)。 《货币互联网，第二卷》。ISBN-13：978-1947910065 课程大纲： 1. **所有权的本质** - 描述：本周我们将研究区块链如何通过电子账本跟踪所有权交易。在物品经历多次转手后，通过查看在区块链中不断增长的数据区块字符串，可以直观地看到每一次交接。 2. **区块链技术的组织应用** - 描述：在第二周，我们将探讨区块链技术系统为不同产业和商业市场带来的广泛好处。同时，我们还会思考区块链技术如何成为管理教育成果和能力的理想系统。 3. **密码学与哈希** - 描述：区块链成功的关键在于哈希值和加密的使用。这些技术使您能够在不透露密码的情况下登录您最喜欢的网站，也使您能够发送私密的加密短信。到本周末，您将应用哈希算法于字符字符串中，并观察结果。 4. **应用哈希** - 描述：在最后一周，您将从单纯的功能讨论中退后一步，思考区块链所做事情的意义。您将应用密码学和哈希于一个简单场景，以确定模拟电子邮件消息的真实性。 通过本课程的学习，您将对区块链技术及其关键组成部分拥有更深入的理解。
Name:The Nature of Ownership
Description:This week we will examine and study the ways that the blockchain keeps track of ownership transactions through the use of electronic ledgers. After an item changes hands many times, one can literally see each handoff by looking at the continuously growing string of data blocks in the blockchain.
Name: Organizational Usage of Blockchain Technology
Description:In this second week we will explore and discuss the vast array of benefits that a blockchain technology system can bring to different industries and business markets. We will also consider together how Blockchain technology is an ideal system to manage educational achievement and merit.
Name:Cryptography and Hashing
Description:The key to the blockchain’s success is the use of hash values and encryption. These are the same technologies that allow you to log into your favorite website without revealing your password and the same technologies that allow you to send a private, encrypted text message. By the end of the week you will apply a hashing algorithm to a character string and see the results.
Name:Applying Hashes
Description:As you will see in this final week, it is sometimes important to step back from a purely functional discussion of what the blockchain can do to what it means when it does it. You will apply cryptography and hashing to a simple scenario in order to determine the authenticity of a simulated email message.
Continue learning about blockchain technology by diving into the nature of ownership and how the blockchain is one way to approach decentralized transaction handling. This course also demystifies cryptography and hashing, which are critical for authenticating users and guaranteeing transaction privacy. This course requires the purchase of two books for the completion of assignments: Drescher, D. (2017). Blockchain Basics: A Non-Technical Introduction in 25 Steps. (ISBN-13: 978-1484226032) Antonoupoulos, A. M. (2017). The Internet of Money, Volume Two. (ISBN-13: 978-1947910065)
