Schedule

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!

Labs and Problem Sets

Submission instructions: For problem sets, email your solutions to 6.892-sp17-staff@mit.edu

Final Projects

A final project is encouraged, but not required, as this is an experimental course. You may form groups of 1-4 students and prepare a presentation and a 4 page paper on one of the following:

  1. Design and implement an application or system (project ideas)
  2. Add a new feature to an existing system like Bitcoin, Ethereum, or another cryptocurrency or shared ledger implementation
  3. Propose a formalization in this space for a topic that has not been formalized yet
  4. Pose and solve an interesting problem
