Fuqua Spring Term I, 2017

Course Description

My 2015 course was the first course offered anywhere in the world focused on blockchain technology. In 2016, the course was offered by the Fuqua School of Business for the first time. The 2017 builds on the 2016 course. Blockchain is a distributed ledger that provides proof of ownership and allows for the efficient, secure exchange of ownership. It is called blockchain because transactions are grouped together in blocks. Each block is cryptographically linked to the previous block. A public blockchain is transparent and distributed and anyone can put it on their computer. It requires no trust. However, you cannot change any entry in the blockchain. It is immutable.

In the most popular version of the public blockchain - the bitcoin blockchain, the blocks are “mined”. The miner takes a group of transactions and adds an arbitrary number called a "nonce" (also known as the "magic number") and applies a cryptographic hashing function (one-way encryption). The nonce is varied because the miner is looking for a very rare resulting hash – currently one with 17 leading zeros. [Think of having five decks of cards. You shuffle and draw the first five cards. You are looking for five consecutive ace of spades. You would have to do this many times to get the desired five cards.] Currently, it takes the network 10 minutes to find this “solution” with 2.1 billion gigahashes being tried every second.

The bitcoinblockchain is secure because to win a new block the admission price is about $500 million of specialized hardware (this would get you 50% of the network hashing power). Hence, it is off limits to almost all hackers. Furthermore, it is not possible to rewrite history. Changing history involves undoing hashes by brute force which is on the order of difficulty of 2255 – approximately the number of atoms in the known universe.

The security is very important. For example, questions over security constrain the widespread adoption of the Internet of Things. Currently someone can hack into your house and turn your thermostat up to 100 degrees – or even worse, hack your car while you are driving (or being driven by a self-driving car). Blockchain makes this extremely unlikely. This is exactly why IBM (leader in IoT) has a team of 30 researchers dedicated to blockchain research. Every major financial institution has teams working on blockchain.

In my opinion, this is an extremely disruptive technology and has its place in every leading business school’s curriculum. However, Duke is the only school offering a course like mine.

This is not simply a course about bitcoin. The focus of the course is blockchain. Bitcoin uses a particular type of blockchain technology. The idea of the course is to understand a disruptive technology and to assess its implications on how business is conducted in the future. Much of our focus is on blockchain technology and the many ventures that have already begun to capitalize this innovation. This network, which includes blockchain, provides a secure way to verify ownership of anything. The security is established by the massive computing power necessary to add to a blockchain. Think of the blockchain as a secure repository of common knowledge. A wide range of items can be attached to the blockchain from ownership of a car or access to cloud computing to medical records. Indeed, it is possible to create algorithmic contracts within this network. This leads to the possibility of disruptions not just in finance (stocks, bonds, etc.) but also in law (simple contracts) and other fields. It is even possible to create what is known as a distributed autonomous corporation – essentially an autonomous computer program that employs people and conducts business as a corporation would.

The course is available to Fuqua students as well as Law students, graduate students, and advanced undergraduates (with the expectation that undergraduate students will demonstrate a strong set of technical skills). Permission of the instructor is required for enrollment of all non-Fuqua students.

Who Am I?

To get to know me, go to my homepage and follow some of the links, for example my Media page or my most recent research papers.

In addition to my job at Duke University, I am Investment Strategy Advisor to the Man Group, PLC. The Man Group is the largest listed hedge fund groupin the world.


There are no prerequisites.

Class Schedule

We meet Tuesday-Friday at 15:00 in Formica Classroom. A full schedule of the class meetings is found in the Class Schedule. However, the schedule is fluid.


The course work mainly consists an entrepreneurial project. There are two deliverables. Groups will identify an interesting company that uses blockchain and explain what they do. [20% of grade.] Finally, and most importantly, most of the course grade is determined by a entrepreneurial group project that is presented at the end of the course. [80% of grade.] The ideal group size is four and ideally we draw students from diverse backgrounds. I will provide a Google sheet with student names and you can add your interests -- and form your own groups from the information provided. At the end of the term, group members score the contributions of each member to avoid free-riding. The project is to pitch a new venture idea linked to blockchain. I have front-ended the course with the basic concept. It is essential that you start work as soon as possible. It is also important to meet with me as a group. Each group will present the last day of classes. You must turn in a 15 page pitch deck as the main deliverable.

Outside Class Contact

E-mail me at At odd hours, you can text me at 919-271-8156 (if I am not available, I simply set to DND, so don't hesitate to text) You can also call me. Again, when I am busy or sleeping, my phone is on do not disturb.

NDAs and Other Legal

NDAs may be required for outside presentations.


There are no required texts in Finance 898. There is an extensive reading list below.

Pre-Class Assignment

If you do not have a bitcoin wallet, you must get one. I recommend Coinbase app (co-founded by a Duke grad). You do not have to add any money to the account. Then send me a request for $10 ( There is an airplane icon in top right. Type in $10. Hit request. Add my email. Please request bitcoin. Coinbase also handles ether (another cryptocurrency) and you can tranfer your bitcoin to ether if you want.

Read whatever you can on bitcoin and blockchain to start with. It is easy to find material and some of that material is listed below. You should look at the original Satoshi Nakamoto paper (it is a great paper but somewhat of a challenge to read if you have no background in computer science). There are now plenty of sites that have introductions to bitcoin and I have listed some useful videos. For example, take the time to view at least one of these videos, such as How Bitcoin Works Under the Hood. You should also be checking the reddit/bitcoin discussion. The course is very short and it is crucial that we get up to speed as quickly as possible.

Guest Appearances

We will have a number of guest appearances. The speakers are complex to organize and almost all will be done via video conference.

Class Topics

See the class schedule tab. The schedule is somewhat fluid in that I may spend longer on some topics and spillover to the next class. I might add or delete topics. I will also be interested in your input for topics.
