Skychain is starting to pre-sale its tokens on December 18, 2017. Skychain is a blockchain-based infrastructure project that will host and train medical neural networks, and allow users to access them.
The research prototypes of neural network-based artificial intelligence systems can already diagnose diseases on par with the best doctors in their field of medicine. The development of the AI-in-medicine market is hindered by a lack of infrastructure that would facilitate transactions between medical data providers and neural network developers. Nowadays, neural network developers have to buy medical data for millions of dollars or form joint ventures with data providers. No wonder high-quality medical neural networks are a rare thing.
