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.

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.

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.

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.

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.

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?

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.
