I am Jef, the maker of Predicto. I've been working on products related to data privacy for the last couple of years and decided to create Predicto on Blockstack, a platform that respects the identity and data of all users.
Because Blockstack is a new experimental platform, Predicto only works on computers (not mobile) using the Chrome browser. If you already have a Blockstack identity, you can check out Predicto in one click. Otherwise, you can create a Blockstack identity for free when signing up for Predicto.
I am happy to answer any questions or comments. If you need help creating your Blockstack ID or logging in, please let me know, I might be able to assist.
