Blockchain infrastructure aimed to host, train and use artificial intelligence (AI) in healthcare. Skychain intends to provide an infrastructure to radically increase the efficiency of healthcare AI development and training. It will make diagnostic AI systems far more accessible and affordable for the consumer by using blockchain technologies to facilitate safe transactions between the key parties. The project is based on the revolutionary approach of using smart contracts to bring together many healthcare big data providers whose data is vital for AI training, thousands of independent AI developers, computational resource providers (owners of master-nodes), and millions of consumers.
