Sebastian Porsdam Mann delivered the talk “Two sides of a coin: ethics, human rights and blockchain technologies” during the Codemotion Berlin 2018 conference. We interviewed Sebastian and asked the following questions: How can Blockchain be implemented in agreement with ethics and Human Rights? What are the Blockchain principles you consider most interesting from an ethical point of view? Are we getting closer to a future in which health data could be shared for investigation? You praise the good uses of Blockchain, but what do you think if the bad ones?
