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.
It could actually be just a promotion of his website but it looks like this provably fair algorithm is kind of new on the market and that could explain why only this website uses it and also why he posted the link here. I've heard some things in the article and they pretend to have created some new algorithms for chance games for provably fairness and provably randomness. I don't know what to say about this since this is still new in the gambling industry but I would stay away from it until will get more info and understanding about how it works and how fair it actually is.
