So, we learned that in Japan there is mymizu, mizu means water, which does the same thing in Japan. And this year the international track also brought someone from India doing a very similar but slightly different idea in India and then using blockchains or other distributed technology. We can then do global coordination based on the local participation and so on. And so, I think this is a beautiful term for data altruism, people who donate non-personal data to make the earth better. I think this is one of the best open digital and green movements that started as part of the presidential hackathon.
