In this 2-day course, we will learn about the history of privacy protocols and explore their use in modern-day technologies and blockchain applications.

From communications to commerce, privacy is a fundamental component of our global society and economy. The mathematical discoveries from the last century have been the backbone to securing technologies we use today and the data that gets shared on them.

Blockchains, one of the newest innovations of our time, has seen skyrocketing interest from all over the world; however, it brings with it the risk of not protecting everyday users, as there are no fundamental privacy considerations. Just as HTTPS was a critical component to the mainstream usability of the world-wide web, security protocols that protect users’ financial and other transactional data are what will open blockchains to everyday use cases.


By the end of this course, participants will gain an understanding of:

  • The history of cryptographic discoveries and applications
  • Privacy protocols built for use in blockchains
  • Why zk-SNARKs are the most advanced privacy construction for blockchains today
  • The current limitations in SNARKs and future improvements
  • The future applications of blockchains enabled with privacy
