Phone: (for emergencies) 720-209-7888 - before you call you need to SMS me with who you are and what class you are in so that I add you to my address book. I get far too many robo-calls to answer unknown phone numbers. Generally I am available from 7AM to 10PM.
12:00 PM - 12:50 PM Classroom Room: 118
- Office: 4081B in the Engineering Building. My office is right across the hall from the Computer Science Department Office.
- Office: Office hours will be Tu/Th from 9:25am to 10:50am and by appointment.
xyzzy - Textbook: We have a textbook for the 2nd 1/2 of the class on Ethereum/Solidity. Solidity has moved from version 5.12 to 5.17 in the past 3 months. The text book for Go is a free online PDF: https://www.golang-book.com/books/intro We will also be using IOHK’s Blockchain. It is programmed in Haskell.
This means that you will need to program in Go and Solidity. We will have some focus on how to learn a new language and become effective in that language.
You must demonstrate working homework to the instructor or to the class grader to pass the class (no matter how many points you get). For code developed in Go, test cases will be supplied. The Go homework are cumulative. Assignment 3 depends on getting a working version of 2 etc.
There will be 9 programming assignments over the course of the semester, as well as one midterm and a final exam. Tests will be 800 points. 400 for the midterm, 400 for the final. 1,400 points are from the homework and paper, 100 to 200 points per assignment.
Midterm will be a short answer and multiple choice online from a test bank.
Final will be online - probably a writing assignment.
| Letter Grade | Points |
|---|---|
| A | 1,800 points or above |
| B | 1,600-1,799 points |
| C | 1,400-1,599 points |
| D | 1,200-1,399 points |
None planned at this time.
Work turned in late will loose 10% per calendar day, down to 40% of the original grade. Nothing may be turned in after the last day of class.
- What is Blockchain / Bitcoin and Why it is Important. In 2009 a person or group of people named Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Electronic Cash System" . The Bitcoin design was revolutionary — it elegantly tied cryptography, game theory, and economics into a trust-less solution to the double-spend problem, and introduced the world to the first “chain of blocks,” a censorship-resistant public ledger protected by proof-of-work. This is a big deal. Unlike traditional payments, Bitcoin transactions don’t rely on a trusted third-party. Anyone can connect to the network and transact, without fear of censorship. Satoshi’s work solved these problems, and founded the field of cryptoeconomics. In 2013, Vitalik Buterin proposed a new cryptocurrency — Ethereum. Ethereum was Vitalik’s answer to Bitcoin’s poor scripting capabilities. Instead of focusing on financial transactions and their outputs, Ethereum transactions are about state: agreeing on a computed state, and transitioning from one state to the next. Each transaction in Ethereum includes a sender, recipient, funds, and data, similar enough to Bitcoin. Unlike Bitcoin, however, a recipient can be a user or a smart contract.
- Gartner group projects that 3% of the world economy will be BlockChain based in 10 years. This is a compounded annual growth rate of 62.2%.
- The Plan - Do lectures in advance of when assignments are due on the material and give students time to do homework. Mark what is going to be tested on.
- This class is not a “heavy” programming class. Yes, you will program but not a huge amount. Unlike a lot of computer science classes this class has a paper and will have test questions involving definitions. We are going to cover some finance, accounting, economics and other topics and not just “how to build a better program.” If you have a limited programming background I will work with you.

The University of Wyoming faculty are committed to helping create a safe learning environment for all students and for the university as a whole. If you have experienced any form of gender or sex-based discrimination or harassment, including sexual assault, sexual harassment, relationship violence, or stalking, know that help and support are available. The University has staff members trained to support survivors in navigating campus life, accessing health and counseling services, providing academic and housing accommodations, and more. The University strongly encourages all students to report any such incidents to the University. Please be aware that all University of Wyoming employees, including student staff, are required to report all Title IX related concerns to the Title IX Coordinator or their supervisor. This means that if you tell a faculty member about a situation of sexual harassment or sexual violence, or other related misconduct, the faculty member must share that information with the University’s Title IX Coordinator. UW’s Title IX Coordinator is Jim Osborn (Manager of Investigations, Equal Opportunity Report and Response). He is located in Room 320 of the Bureau of Mines Building, and can be reached via email at [email protected] or via phone at 766-5200 or 766-5228. For more information, go to: http://www.uwyo.edu/reportit/learn-more/faqs.html .
Attendance is critical. There is no text book for ALL of the material. The only way to know what you need to know is by attending class. If you have an excused absence that is fine, try to get notes from the day you missed from one of your classmates. Just don't skip!
At all times, treat your presence in the classroom and your enrollment in this course as you would a job. Act professionally, arrive on time, pay attention, complete your work in a timely and professional manner. You will be respectful towards your classmates and instructor. Spirited debate and disagreement are to be expected in any classroom and all views will be heard fully, but at all times we will behave civilly and with respect towards one another. Personal attacks, offensive language, name-calling, and dismissive gestures are not warranted in a learning atmosphere. As the instructor, I have the right to dismiss you from the classroom.
The University of Wyoming values an educational environment that is diverse, equitable, and inclusive. The diversity that students and faculty bring to class, including age, country of origin, culture, disability, economic class, ethnicity, gender identity, immigration status, linguistic, political affiliation, race, religion, sexual orientation, veteran status, worldview, and other social and cultural diversity is valued, respected, and considered a resource for learning.
If you have a physical, learning, sensory or psychological disability and require accommodations, please register as soon as possible and provide documentation of your disability to Disability Support Services (DSS), Room 109 Knight Hall. You may also contact DSS at (307) 766-3073 or [email protected]. Visit their website for more information: www.uwyo.edu/udss
Don't cheat on the exams. I expect you to take full advantage of all the online resources you can get your hands on. That includes Stack Overflow, Github etc. If you do use someone else's code, put in a link to where you found it. Don't cheat on the projects - do you own work. Most of the learning in the class is from doing the projects.
All deadlines, requirements, and course structure are subject to change if deemed necessary by the instructor. Students will be notified verbally in class, on our WyoCourses page announcement, and via email of these changes. I do travel during the semester. Class could be canceled or assignments due dates changed.
