LEMONCHAIN's healthcare ecosystem aims to build a metaverse called LEMONVERSE that can decentralize personal information in the healthcare data field and raise awareness of user (patient) administrator authority. By making it possible for individuals to easily access and utilize their medical information, information asymmetry between medical institutions and patients is reduced, patient participation is enhanced, and a consumer-led medical system can be established. For example, in the present age, patients waste time and money by visiting 2-3 or more hospitals for treatment, but reducing the process through the metaverse space is expected to increase accessibility and reduce costs.
