课程名称: 区块链系统 课程概述: 本课程将让您了解区块链如何验证交易并将数据分发给网络中的节点。我们将讨论如何将多个版本的区块链调和为一个版本，探讨区块链的局限性，以及区块链技术在组织中的应用。 课程要求: 学员需购买以下两本书以完成作业： 1. Drescher, D. (2017). 《区块链基础：25步非技术性简介》。 (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. **认证交易与数据分发** 在第一周，我们将研究区块链数据如何在点对点网络的节点之间共享，以及节点的互联性是如何管理的。 2. **确定区块链的权威版本** 接下来，我们将进一步了解节点如何向数据结构中添加区块，以维护一致的交易历史。同时，我们将探讨由于意外的节点故障或故意恶意行为而导致的多种历史版本的出现。我们将学习如何通过最长链标准和最重链标准来判断哪条历史是正确的，并在本周的作业中实践所学原则。 3. **区块链的局限性** 区块链并不是完美的系统，确实存在一些限制。本周，我们将探讨区块链的一些约束以及导致这些限制的问题。 4. **区块链的组织应用** 在课程的最后一部分，我们将探索区块链方法在去中心化传统集中产业中的应用机会，讨论如何将区块链方法应用于加密金融以外的其他行业。 本课程旨在增强您对区块链技术的理解，并帮助您探索其在各个领域的潜在应用。
Name:Authenticating Transactions and Distributing Data to Peers
Description:During this initial week we will start by looking at how the blockchain data are shared among nodes in the peer-to-peer network over the internet and how the interconnectivity of the nodes is managed.
Name:Determining the Canonical Version of a Blockchain
Description:We will continue to look more closely at how nodes add blocks to the data structure with the goal of maintaining a consistent transaction history. We’ll also see that multiple histories can sometimes arise due to a variety of factors ranging from benign, but unpredictable, node outages to intentional malfeasance. This requires that the system have a means of collectively determining which single history is the correct one. We’ll explore two approaches to achieve this: the longest chain criterion and the heaviest chain criterion and practice applying the principles that we have learned in this week’s assignment.
Name:Blockchain Limitations
Description:The blockchain is not a perfect system and indeed has its limitations. We will explore some of the constraints of the blockchain and address the issues that cause such limitations.
Name:Organizational Applications of Blockchain
Description:We will finish the course by exploring other opportunities for using a blockchain approach to decentralize what have been heretofore centralized industries in which individual entities have controlled or consolidated information. We will develop ideas for applying a blockchain approach to industries other than cryptofinance.
Learn how the blockchain authenticates transactions and distributes data to peers — nodes connected to the network. This course shows you how multiple versions of a blockchain are reconciled into one, discusses blockchain limitations, and delves into organizational applications of blockchain technology. 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)
