Commit / reveal, hashes, and how to play "Rock, Paper, Scissors" over Slack
Last week my course Security Token Strategy at University of Nicosia’s IFF started for real, and this has kept me pretty busy. Today I recorded a number of videos for the course assignments, so I did not get around recording anything for the podcast. Instead I will be sharing one of the videos with you. It is about hash functions, and more specifically about the commit / reveal pattern that they allow implementing. To make it a bit more fun we are using it to play Rock, Paper, Scissors over Slack.
The course is now full, but we’ll run it again in the not too distant future. If you are interested, contact me  or have a look at the course page .
This podcast also exists as a YouTube video .
