MIT Mini-VDF Day 2019

  • 32 Vassar Street Cambridge, MA, 02139 United States (map)

Please join us on May 17 for a series of talks and workshops on the topic of Verifiable Delay Functions (VDFs)!

VDFs are a relatively new cryptographic primitive that have taken the blockchain world by storm. They provide functionality that is difficult or impossible to get in other ways in fully decentralized systems, including unbiasable/unstoppable randomness and a proxy for passage of time. For information and background about VDFs in general see We’ve lined up four very exciting talks for the morning. The first two introductory talks will provide perspective on VDFs and motivate their importance from a blockchain point of view. The second two talks will dive deep on two of the challenges related to practical applications of VDFs. We hope you’ll join us, learn about some of the ongoing activities around VDFs, and participate in this work going forward!
