Description: This course is about the principles and core techniques of shared public ledgers, with an emphasis on Bitcoin and distributed consensus. Topics include Bitcoin, Byzantine agreement, authenticated data structures, Lightning networks, proof of stake, and new techniques to implement a shared public ledger.
NOTE: The schedule is in flux and subject to change.
We are occasionally providing our lecture notes in the interest of transparency. Note that they are rough, probably have mistakes, and are almost definitely incomplete. In addition, they might not accurately reflect what happened in class. Use at your own risk!

- Design and implement an application or system (project ideas)
- Add a new feature to an existing system like Bitcoin, Ethereum, or another cryptocurrency or shared ledger implementation
- Propose a formalization in this space for a topic that has not been formalized yet
- Pose and solve an interesting problem
- Untraceable Electronic Cash
- Universal Electronic Cash
- Bitcoin whitepaper
- How the Bitcoin Protocol Actually Works
- Bitcoin Systemization of Knowledge
- Princeton textbook (pre-published online verison)
- Princeton class
- Stanford class
- UIUC class
