Verifiable Delay Functions

Verifiable Delay Function (VDFs) are a relatively new cryptographic primitive that have taken the blockchain world by a 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 https://vdfresearch.org/.

We’ve lined up six 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 next four talks will dive deep on 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


VDF Day 2019 - Morning Session


Workshops

There were parallel workshops in the afternoon on the following topics.

1. RSA MPC Protocol and Ceremony

2. Applications of VDF in blockchains

3. Future directions for VDFs - quantum proof, S[N/T/H]ARKs, new constructions

4. Building VDF hardware, including non-linear and exotic approaches
