The City of Granada has just produced a video summarizing the cooperation with China on the opportunities and challenges that blockchain technology represents for cities. The video refers to three webinars dealing with smart city, circular economy and health/biotechnology that were implemented in October and November 2020. Moreover, Granada launched a beta version of the online platform to support the development of future joint projects on blockchain, involving the cities, research centers and companies participating in the webinars (who are pilot cities of the IUC programme). All activities were supported by the IUC programme within the competitive award granted to Granada.
