ACGG (ACGG great health ecology) is a large health ecological intelligent blockchain network based on blockchain technology. Through the three modules of Olife, Olivia, and Oleaf, it customizes a comprehensive portrait of people's health information that is constantly self-improving on the blockchain, provides a general artificial intelligence doctor, and opens up a complete set of medical and health service systems. In the ACGG network, users can fully control their own health data, and have personalized health management by artificial intelligence doctors, so as to meet their needs in the whole process of medical health. At the same time, ACGG's two-tier token system can also encourage all participants to contribute to the healthy development of this big health network in different ways, truly achieve point-to-point precise connection between the supply side and the demand side of medical resources, and form a Decentralized, non-tamperable big health ecological intelligent blockchain network.
