And how will you protect the data you get? You will basically know exactly what your users do?
Medipedia is a decentralized platform based on Ethereum blockchain where patients can search complete and accurate information about various healthcare service providers. This platform can also help medical institutions and hospitals to connect with patients. Medipedia platform stores medical and health related information in IPFS (Interplanetary File System), which is created at Protocol Labs.
Searching a right medical service provider at Medipedia platform involves creating a message request and platform will send the request to all the matching service providers. Service providers may later reply to message request. Every message request and its replies are stored in IPFS and IPFS generates a hash that is finally updated in Ethereum blockchain.
