I need a network where different pharmacy databases connect to measure how many products of a particular brand were bought by the same user and thereby give them a discount. The information that we are gonna use are CPF (brazilian ID), bar code, time stamp, number of previous products acquired and pharmacy that sold the product. This information must be in accordance with GDPR and guarantee the anonymity of the user, using for example the private fabric. Maximum term 10 days. The main objective here is the pharma brand to obtain all that information to give the maximum discount to the user.

Hi, How are you today? Yes this is a perfect case for using a hyperledger fabric blockchain. we are already working with 3 hyper ledger app for our client, all on the blockchain and below are the projects that we are working with 1) For educational qualification verification. 2) for Product tracking visibility (yours is similar) 3) for IoT with hyperledger to store sensors details For your app, we should use below Hyperledger structure: 1 Peer node 1 orderer node 1 channel and 1 organization. i think it will serve your purpose. we will use Node.js to write the chaincode and deploy on the channel. So far yes we can achieve anonymity for user data and we can store all the information CPF (brazilian ID), bar code, time stamp, number of previous products acquired and pharmacy that sold the product in the blockchain. So any user who comes to a site, can search the product? or we need to create some kind of a dashboard to know how much that user has purchased? Please share more details, mockups of the app so that we can decide the timeframe. Looking forward to work with you! Thanks, Jay

Hello, I am a blockchain generalist, with wide experiences in various platform's. Currently working on Ethereum's smart contract development. I have some familiarity with Fabric and Hyperledger ecosystem though I may need to take that amount of time since it has been a while. It is more convenient if I first develop the initial PoC and show you the result to see if it solves your problem and then we will see where we are going from there.
