As for the USA Presidential Forecast I used my algorithm with some (better: many) needed changes to adapt it to the Italian Referendum scenario.
Today, it is not possible to publish the results due to the Italian laws about referendum but I created a .png file that shows them. Then I obtained an on-line timestamp by http://www.originstamp.org/ and so I will be able to publish the .png forecast file tomorrow proving exactly when I created it.
Moreover, I published a Tweet with the file hash of that .png file in order to publicly prove it:
