The VDF Challenge

A few months ago we wrapped up our initial VDF implementation competition and were amazed by the excellent quality of the submissions. The top three contenders each came in at under one minute (the reference implementation was 169 seconds). Five other teams also submitted implementations which were faster than the reference. All of the submissions were open-source, and can be found here. The award total was originally $100,000, but because of the hard work that ll the teams put into the competition, we decided to award $2,000 to each team who submitted an entry, bringing the total prize money awarded to $116,000.

We are proud to announce a second competition, challenging entrants to improve on our new reference implementation.

Two Tracks

The second VDF competition will be split into two tracks:

1. SIMD and GPU optimization allowed

2. SIMD and GPU optimization not allowed

This is to help us separate the different kinds of optimization. We expect that the entries which use the optimizations allowed in track 1 will be faster, however there is no requirement for track 1 submission to use those techniques. This means that all track 2 submissions are also eligible for submissions to track 1. The winners of each track will receive $50,000. Individuals and teams are invited to join. Entrants will all have access to the specialized computers in olive’s laboratory. Specifications of the reference hardware and further technical details are available on our GitHub. You can view our pre-commitment here. Contestants will be able to communicate with olive during the competition via a secure Keybase channel.
