Pharmaceutical supply chain using Hyperledger sawtooth

Description

The supply chain involves:

1. Manufacturer
   The manufacturer manufactures the medicine in units, or batches, identified by a batchID. The manufacture now owns the batch. The manufacturer can send this batch to a distributor.
2. Distributor
   The distributor now has the option to either accept or reject the batch. If rejected, ownership doesn't change; the batch remains under the manufacture. If the batch is accepted, ownership is transferred to the distributor. The distributor can send this batch to a pharmacy.
3. Pharmacy
   The pharmacy has the option to accept or reject the batch; this is similar to the distributor.
4. Admin
   The admin can add manufacturers, distributors and pharmacies.

Details

1. Navigate into the folder in the terminal.
   Bring up the docker containers using the command:
   $ [sudo] docker-compose up
   This starts the client, processor, network, validator, dev-mode consensus engine.
2. Open a new terminal to enter into the pharma-client docker container.
   $ [sudo] docker exec -it pharma-client bash
3. Install flask.
   # pip3 install Flask
4. The four players - admin, manufacturers, distributors and pharmacies - each have their own webpages, hosted on different ports.
   Open 4 new terminals, one for each:
   • # python3 admin.py
   • # python3 manufacturer.py
   • # python3 distributor.py
   • # python3 pharmacies.py
5. Open the webpages in a browser:
   • 0.0.0.0/5000 - for the admin
   • 0.0.0.0/5010 - for the manufacturer
   • 0.0.0.0/5020- for the distributor
   • 0.0.0.0/5030 - for the pharmacy
