课程名称：梅克尔树与加密货币 课程概述：本课程旨在帮助学员应用之前区块链课程中学习的密码学和哈希知识，了解梅克尔树在将新区块（代表新交易）添加到区块链过程中的作用。同时，课程还介绍了工作量证明（Proof of Work）和权益证明（Proof of Stake）的概念，这两者在确保区块链的完整性方面发挥着重要作用。 课程要求：完成作业需购买两本书籍： 1. Drescher, D. (2017). 《区块链基础：25步非技术性介绍》。ISBN-13: 978-1484226032 2. Antonoupoulos, A. M. (2017). 《货币的互联网，第二卷》。ISBN-13: 978-1947910065 课程大纲： 1. **哈希与梅克尔树** - 描述：这一周将介绍更为技术性的概念，包括数据块如何组装，以及如何使用哈希值和加密技术来确保添加到区块链的数据块的顺序和完整性。 2. **哈希与加密货币介绍** - 描述：在这一周，我们将应用之前的学习，研究哈希值和哈希序列。您将练习为特定哈希难度水平组装区块头哈希值。 3. **工作量证明与权益证明 I** - 描述：经过哈希函数和哈希难题的探讨后，我们将集中讨论工作量证明，这是一种计算耗时且困难的区块链修改方法。同时，我们会关注权益证明，它是一种修改区块链的替代方案，侧重于修改已经代表区块链大部分的较大节点。我们将调查这两种方法的利弊，并准备应用工作量证明和权益证明的原则。 4. **工作量证明与权益证明 II** - 描述：在最后一周，比较工作量证明和权益证明后，我们将探索并描述结合这两种方法最佳特点的替代方案，以完成本课程的最终作业。
Name:Hashing and The Merkle Tree
Description:This first week introduces more technical concepts including how we look at the manner in which data blocks are assembled as well as how hash values and encryption are used to ensure the proper sequencing and integrity of data blocks that are added to a blockchain.
Name:Hashing and an Introduction to Cryptocurrencies
Description:This week we will apply what we have learned up to this point about hash values and hash sequences. You will practice assembling block header hash values for a specified hash puzzle difficulty level.
Name:Proof of Work and Proof of Stake I
Description:Now that we have investigated hash functions and hash puzzles, we will focus on proof-of-work, which is an approach to modifying the blockchain that can be difficult and time-consuming to compute. We will also focus on proof-of-stake, an alternative to updating the blockchain in which larger nodes are modified that already represent a large portion of the blockchain. We will investigate the pros and cons of each approach and prepare to apply the principles of proof-of-work and proof-of-stake.
Name:Proof of Work and Proof of Stake II
Description:In this final week, after comparing proof-of-work and proof-of-stake, we will explore and describe alternative approaches that combine the best features of proof-of-work and proof-of-stake in this course’s final assignment.
Apply what you have learned about cryptography and hashing in previous blockchain to the Merkle Tree, which underlies the process of adding new blocks — representing new transactions — to the blockchain. This course also introduces the concepts of proof of work and proof of stake, which play an important part in ensuring the integrity of the blockchain. 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)
