VIC (Vital Index Tracing Chain) is a decentralized healthcare ecosystem built on blockchain technology. Unlike traditional centralized healthcare systems, VIC leverages blockchain technology and token economic models to create a highly available, secure, and efficient global healthcare service system where every participant can benefit from the healthcare ecosystem constructed by VIC. By introducing and integrating multiple stakeholders in the healthcare industry, including hospitals, clinics, pharmaceutical companies, research institutes, insurance companies, etc., and establishing a reasonable token incentive system, it utilizes the transparency and security features of blockchain for multi-party data authorization and sharing. This ensures that each user can access high-quality global healthcare and financial services, while service providers can reach their most suitable customer base, thereby promoting the healthy development of the entire VIC ecosystem.
