课程名称：区块链技术导论 课程概述：在这门专业化课程的第一部分，我们将讨论互联网在商业和经济活动中的局限性，并解释区块链技术如何为未来带来新的方向。完成此课程后，您将能够解释什么是区块链、它的工作原理以及为什么它是革命性的。您将学习诸如挖矿、哈希、工作量证明、公开密钥密码学和双重支付问题等关键概念。您还会描述区块链技术的七个设计原则及其开发者面临的挑战。此外，您将了解区块链生态系统中的各个参与者，并考虑自己在区块链革命中的角色。 课程大纲： 1. **互联网的第二个时代**：讨论互联网如何连接全球数十亿人以及其在信息传递方面的优越性，但对商业变革的微小影响。通过介绍区块链作为“信任协议”，解释其如何标志着互联网的第二个时代。 2. **区块链设计原则**：提出七个设计原则，帮助塑造数字经济的新未来。将通过当前存在的问题和区块链的相关突破，讨论这些原则在未来数字经济中的影响。 3. **公开与私有账本**：讨论交易和合同公开揭示的优缺点，以及分布式账本的实施、应用与可能的监管如何影响信息披露及经济互动。 4. **区块链生态系统**：探索包括行业先锋、风险投资家、开发者、政府及用户在内的九类利益相关者在区块链生态系统中的角色及视角。 5. **区块链实施挑战**：分析十种实施挑战及其潜在解决方案，以确保区块链技术的承诺得以实现。 本课程旨在帮助学习者理解区块链技术的基本概念、应用及其在未来的潜力，引导他们思考自己在区块链革命中可以扮演的角色。
Name:The Second Era of the Internet
Description:The Internet connects billions of people around the world, and is great for communicating and collaborating online. However, because it was built for moving and storing information, and not value, it has done little to change the way we do business. Now, for the first time in human history, two or more parties anywhere in the world can transact and do business peer to peer using the blockchain. In this module we introduce blockchain as “the trust protocol,” and explain how it represents the second era of the Internet. We describe how blockchain technology establishes trust—not through powerful intermediaries, but rather through collaboration, cryptography and clever code.
Name:Blockchain Design Principles
Description:We believe that the next era of the digital economy can be shaped around a set of blockchain design principles, which can be used for creating software, services, reinventing business models, markets, organizations, and even governments. This module frames the blockchain revolution around seven design principles. For each principle we describe a current problem to be solved, identify “blockchain breakthroughs” to these problems, and discuss the implications of these breakthroughs on the digital economy. We hope that these design principles will assist learners in contemplating their roles and their futures in the blockchain revolution.
Name:Public and Private Ledgers
Description:The advent of blockchain technology forces us to reconsider the upside and downside of public revelation of transactions and contracts. The implementation, application, and possible regulation of distributed ledgers involve choices that will critically affect information disclosure and economic interactions. Whether the ledger is public and permissionless, such as the Bitcoin or Ethereum blockchains, or private and permissioned, such as the Ripple or Hyperledger implementations, in principle transactions on a blockchain have a high native level of transparency. In this module, you will learn how privacy can can be protected in both public and private ledgers using both procedural and technological methods.
Name:The Blockchain Ecosystem
Description:Although blockchain technology emerged from the open source community, it quickly attracted many stakeholders, each with different backgrounds, interests, and motives. In this module, you will explore the roles and perspectives of nine categories of stakeholders within the blockchain ecosystem, including industry pioneers, venture capitalists, developers, governments, regulators, leaders, and end users.
Name:Blockchain Implementation Challenges
Description:Like every revolutionary technology, the blockchain has its upside and its downside. In this module we discuss ten implementation challenges which must be overcome as we transition to the second era of the Internet. For each challenge, you will also learn about potential solutions and what we can do to ensure the fulfillment of the blockchain’s promise.
In this first course of the specialization, we will discuss the limitations of the Internet for business and economic activity, and explain how blockchain technology represents the way forward. After completing this course, you will be able to explain what blockchain is, how it works, and why it is revolutionary. You will learn key concepts such as mining, hashing, proof-of-work, public key cryptography, and the double-spend problem. You’ll be able to describe seven design principles for blockchain technology, and the challenges facing the people developing it. You’ll also meet the players in the blockchain ecosystem, and consider your own role in stewarding the blockchain revolution.
