课程名称：区块链商业模式 课程概述：区块链是一种新兴且具有高度颠覆性的技术，但其内涵尚不为人们充分理解。在本课程中，您将学习区块链的基本概念以及其通过代币化在加密货币和其他实际应用中创造价值的方式。这些应用包括稳定币（如Facebook的Libra和JP Morgan的JPMCoin）、机器间支付、身份保护、供应链管理（如沃尔玛、马士基、IBM）、安全投票、去中心化交易、去中心化金融、产权转移、央行法定数字货币（例如美联储数字货币Fedcoin和中国数字人民币）、药品发放、私密记录、知识产权、财务报告及媒体与广告等。课程的目标是：（i）深入理解各种区块链技术；（ii）确定区块链技术可应用于解决重要问题的具体商业场景；（iii）选择最有可能成功解决特定问题的区块链技术；（iv）详细阐述该新技术所带来的风险。 课程大纲： 1. **区块链概述**：介绍区块链的基本概念和当前及未来的应用。 2. **密码哈希**：讲解密码哈希的基本原理，以及其在区块链中的应用。 3. **区块链加密与签名**：介绍数字签名算法及其在交易验证中的作用。 4. **比特币与其他区块链**：分析比特币区块链的运作原理和共识机制，比较不同区块链技术。 5. **使用区块链**：评估区块链在各种应用中的实用性。 6. **共识机制**：研究区块链技术的不同实施方式，如工作量证明和权益证明。 7. **加密应用的价值**：提供评估区块链创业公司的实用清单。 8. **监管环境与金融科技的未来**：探讨区块链技术的监管问题及其对创新的影响，展望去中心化金融的未来。 本课程将为您提供全面的区块链商业模式视角，帮助您在未来的金融科技领域中游刃有余。
Name:Blockchain Overview
Description:A helicopter tour of the essential concepts of blockchain - each of which will be detailed later in the course. Blockchain as a technology is defined in terms of the commonalities present in blockchain applications. There is also an introduction to both current and future blockchain applications.
Name:Cryptographic Hashing
Description:Almost all blockchains use some sort of cryptographic hashing. Hashing is a one way function where any input of arbitrary size can be uniquely expressed as a string of characters. Any change in the input cause the hash to change. Hashing is a one way function: it is easy to go from the input to the hash but extremely difficult to go the other way. As such, cryptographic hashing should not be confused with encryption where an encrypted message can be decoded.
Name:Blockchain Encryption and Signatures
Description:Some basic knowledge of encryption techniques is essential for understanding blockchain technology. This module focuses on digital signature algorithms. When a transaction is placed on a blockchain, it is signed by the owner. With the owner’s public information and the signature, we can quickly determine if the signer is really the owner.
Name:Bitcoin and Other Blockchains
Description:Bitcoin was the first cryptocurrency and the first large scale use of blockchain technology. This module explores how the bitcoin blockchain works. We detail the mechanics of transactions and there is an introduction to the consensus mechanism called Proof of Work. This provides a foundation to look at other blockchain implementations. We highlight the difference between bitcoin, ethereum and other technologies like Hyperledger.
Name:Using Blockchain
Description:With a knowledge of the mechanics of blockchain technology, students are now able to determine the usefulness of the technology in various different applications. We focus on both the current applications as well as applications that are in process but not yet public.
Name:Consensus
Description:There is no single blockchain technology and there are many ways to implement blockchain technology. The choice of technology crucially depends on the application. In this module, we study Proof of Work, Proof of Stake as well as some other mechanisms. Consensus is an active area of research in the blockchain space.
Name:Value of Cryptoapplications
Description:There are thousands of new ventures that are deploying blockchain technology. How do we assess whether these ventures are viable - in the context of either investing for one of these companies or working for them. This module provides a checklist for evaluating cryptoventures. This list includes important questions such as: a) what problem is being solved? b) is the problem an important problem? c) is blockchain the best technology to solve the problem? and d) what type of blockchain technology is best suited to solve the problem?
Name:The Regulatory Environment and the Future of Fintech
Description:Given this is a new technology, regulators need to both learn about the technology and develop guidelines. The module explores some key regulators in the US such as the SEC and the CFTC and the basic legal background that guides their regulatory framework. We also explore the regulatory concept of the “right touch”: if the regulations are too harsh, then innovation is stifled and driven off shore - if regulations are too lax, then you invite a high level of fraud. The module ends with a general discussion of the future of Fintech, in particular, decentralized finance.
Blockchain is an emerging and highly disruptive technology that is poorly understood. In this course you will learn what blockchain is and how it can create value by tokenization in cryptocurrencies and in many other practical applications. The applications include: stablecoins (like Facebook’s Libra and JP Morgan’s JPMCoin), machine to machine payments, identity protection, supply chain management (Walmart, Maersk, IBM), secure voting, distributed exchanges, decentralized finance, property transfers, central bank fiat crypto (e.g., Fedcoin and China’s digital Renminbi), dispensing prescription drugs, private records, intellectual property, financial reporting, and media and advertising, to name a few. The goals of the course are to: (i) provide an advanced understanding of the various blockchain technologies; (ii) determine the specific business situations where blockchain technology can be deployed to solve important problems; (iii) select the specific blockchain technology that has the best chance of success for a particular problem; and (iv) detail the risks presented by this new technology.
