Electronic Health Record Blockchain Based Platfrom - Project

Tech stack

- Hyperledger Fabric blockchain (Node SDK JavaScript)
- Node.js
- Next.js
- IPFS

Steps to setup project

Download fabric binarys and fabric sample repo

$ ./install-fabric.sh 

To test network

$ cd fabric-samples/test-network
$ ./network.sh up

$ docker ps    // to check running container or check in docker desktop

$ ./network.sh down     // to down network

to run network with ca and create mychannel

$ cd fabric-samples/test-network

Create network with ca cert: 

$ ./network.sh up createChannel -ca -s couchdb

### Chain code deployment command

• Deploy chain code

  $ ./network.sh deployCC -ccn ehrChainCode -ccp ../asset-transfer-basic/chaincode-javascript/ -ccl javascript

  *Down Network - only if you want to stop network or close system

  $ ./network.sh down

Register Admin

$ cd server-node-sdk/
$ node cert-script/registerOrg1Admin.js
$ node cert-script/registerOrg2Admin.js

onboard script

$ node cert-script/onboardHospital01.js 
$ node cert-script/onboardDoctor.js

$ node cert-script/onboardInsuranceCompany.js 
$ node cert-script/onboardInsuranceAgent.js

*** you can use script to call chaincode and perform read and write opration on blockchain ledger. - optional ***

start node server to use api

$ npm run dev

API List

1. registerPatient - as Patient
2. loginPatient - as Patient
3. grantAccess - to doctor from Patient
4. addRecord - of Patient
5. getRecordById - of Patient 
6. getAllRecordByPatienId - filter record by patient
7. fetchLedger - fetch all transaction only admin can fetch.

chaincode logic

- lets first understand the actors in our chaincode

1. Goverment - network owner
2. Hospital - Network orgination 
3. Practicing physician / Doctor - member of hospital
4. Diagnostics center - org OR peer of hospital
5. Pharmacies - Org OR peer of hospital
6. Researchers / R&D - org
7. Insurance companies - org
8. Patient - end user
