Quentin and Takfarinas won the third prize at the biggest Blockchain Hackathon (https://blockchain-hackathon.com/) in Europe which happened in Dublin between the 6th and 8th November with a project called "Open Charity", a safe, decentralized system allowing to issue IOUs ("I Owe You" tokens) for the benefit of Charity. The project was designed to facilitate the request for assistance by global charities or local entities and make the whole process of giving moneys, food or furnitures, easier and more transparent.
