Welcome to GMedChain

We are providing healthcare supply chain solutions so more people have access to safe, affordable & efficient
medical care around the world.

Lost supplies, fraudulent medicine, and supply chain confusion; in times like this, we understand medical equipment is a public resource, akin to the water we drink, the air we breathe, and the levels of freedom we should enjoy as a human right. To that end, visibility must be pervasive throughout the medical supply chain in order to better serve the public.

With more than 3 million cases of COVID-19 worldwide, hospitals around the world are struggling to obtain safe and reliable supplies. Frontline healthcare workers are running low on resources, with no medicine to help.

According to WHO, it is estimated that up to $200 billion worth of counterfeit pharmaceutical products are sold globally every year, according to the United Nations, up to US$2 trillion of procurement costs could be lost to corruption and fraud.

In real life, this means vital services are delayed, much-needed equipment never reaches hospitals, critical infrastructure is never built, and people's lives and well-being are needlessly at risk.

How do we improve this long and costly supply chain system so that more people can have timely access to better health services in both normal and difficult times?

That is GMedChain.

The platform

We've built a platform based on the Baseline Protocol, a joint project between Consensys, Microsoft and EY.

The GMedChain platform code is currently embedded inside the /radish-api directory. This name, Radish, came from the initial name of the Baseline protocol PoC, but we will rename it later. You don't need to deep dive into this directory if you just want to deploy the platform: a Makefile is available, described in the section right above.

Quickstart

A Makefile has been included for convenience; most of its targets wrap npm, docker and solc invocations.

Just want to get the GMedChain platform running locally? The following sequence will build the monorepo, start the GMedChain platform stack locally, deploy contracts and run the full test suite. *Note: this typically takes at least 20 minutes to complete.

make && make start && make test

The demo UI

After running the above (make test optional) you can view the Radish34 demo by opening http://localhost:3000 in your browser.

Here are the targets currently exposed by the Makefile:

Target	Description
make	Alias for make build.
make build	Build all modules within the monorepo.
make build-containers	Dockerize all modules within the monorepo.
make clean	Reclaim disk used by all modules (i.e. node_modules/) and the local docker environment. This effectively uninstalls your local GMedChain platform environment and will require building from scratch.
make contracts	Compile the Solidity contracts.
make deploy-contracts	Deploy the Solidity contracts. Requires the stack to be running.
make npm-install	npm i wrapper for all modules in the monorepo.
make start	Start the full GMedChain platform stack. Requires docker service to be running with at least 12 GB RAM allocation.
make stop	Stop the running GMedChain platform stack.
make system-check	Verify that docker is configured properly.
make restart	Stop and start the docker stack.
make reset	Clean the docker environment by pruning the docker networks and volumes.
make test	Run the full test suite. Requires the stack to be running.
make zk-circuits	Perform zk-SNARK trusted setups for circuits contained within zkp/circuits

Running the GMedChain platform

To run the GMedChain platform application, follow the instructions in radish34/README.md.

cd radish34 and go from there 🚀

What is here?

The root directory of this repo (where this Readme currently lives) contains the following folders:

.
├── baseline  <-- Future home to the Baseline Protocol libraries
├── bin <-- Scripts to run across the entire project
├── docs <-- auto-generated and artisanal hand crafted documentation 
└── radish34 <-- The demonstration POC (you probably are looking for this)

Running scripts across the project

To use the top level scripts (currently just documentation auto-generation and collection) do the following:

Required: NodeJS 11.15 (nvm is recommended)

• run make npm-install to install the top level packages

optionally make clean to clean out any node_modules folders installed by the make npm-install command.
