Verifiable Delay Functions take a prescribed time to compute, even on a parallel computer, yet produce a unique output that can be efficiently and publicly verified.
We implement the approaches described in the following papers:
- Sloth(Quadratic Residue) Verifiable Delay Functions. Boneh, 2018
- Simple Verifiable Delay Functions. Pietrzak, 2018
- Efficient Verifiable Delay Functions. Wesolowski, 2018
To build from the source code you need to have a working Go environment with version 1.12 or greater installed.
