The problem Pharmaz solves

***Pharmaz ***is a decentralized application deployed on Polygon Mumbai testnet.
The purpose of Pharmaz is to transform prescriptions into NFTs.
The problem statement Pharmaz choose is the number 3 solutions that can be deployed in a healthcare setting, for tracking and manage prescription for drugs or medicines.

Process
By using this doctor will no longer need to give you a prescription paper that is difficult to manage or take care of, instead doctor will provide you a prescription in form of NFT and send it directly to your wallet address.
The next step is you need to go to a pharmacy (shop) to use your prescription as permission to buy that drug/medicine that was specified in the prescription.
After you have done, the pharmacy shop will keep your prescription NFT and return you a receipt NFT which keeps all information (Date time, drug name, etc.) just like the prescription.

***Benefits ***

• Keep track
  If something is fishy in the process and the police come to investigate it is much easier to keep track on the blockchain which already records transactions.
• Safer
  As all data and information was kept on the blockchain it is easier to catch the criminal. For example, you may be seen some guy who got 20 prescription NFTs in only 1 week.
• Manage
  As a form of NFTs, you will no longer need to take care of it, like before you need to keep the receipt after buying a drug for at least 1-2 weeks but with Pharmaz it's all live and fresh on the blockchain.

Technologies

• Polygon
  The fastest and most reliable blockchain that takes less gas fee.
• IPFS
  The distributed system for storing and accessing files. Used for keeping prescription and receipt information and NFTs metadata.
• Spheron & Filecoin
  With the combination of this two, I can easily deploy my decentralized application on the blockchain network.

Challenges I ran into

The problem I found is that at first, I want the pharmacy as a system to be the one that ran a smart contract for transferring a prescription with a receipt but I can't find a way to let the system run a smart contract and pay their gas. so I decide to let the patient be the one who ran this smart contract instead and it work fine in the smart contract before receiving a receipt they need to provide prescription NFT first which can be used as an authentication for a patient.
