HealthChain is built on technologies such as blockchain, artificial intelligence, and the Internet of Things to realize an intelligent healthcare value chain – HealthChain. The HealthChain protocol consists of four major modules: security, authentication, smart networking, and data storage, all serving as the underlying infrastructure for HELC. HealthChain will also integrate with other AI-capable DAPPs to continuously expand the capabilities of HELC. Connecting health examination institutions, insurance companies, medical institutions, medical technology service companies, users, doctors, and more, HealthChain enables every participant on the chain to create value, contribute value, and share in that value.
