Seems like a self promotion. No independent source mentioned and the so called algorithm is only used for the site d2w bet. I don't mean to raise a suspicion about it's fairness but it would be wise to stick with traditional way of proving fairness until we find an independent study about the claims of golle algorithm.
Well, it's an article on medium so anybody is free to question it. The author has done a good job of explaining it in a detail but I'm no cryptographer or probability expert to find the challenges in the said algorithm. I don't know who invented it but if it does what its supposed to do then why doesn't the creator patent it?
