We're excited to publicly announce what we’ve been working on Supply-Chain management! Read more




Healthcare has become one of India’s largest sectors- both in terms of revenue and employment. It is growing exponentially due to its strengthening coverage, services and increasing expenditure of public as well as private players. It is expected to increase three folds to Rs 8.6 trillion (US$ 133.44 billion) by 2022, however despite the growth there are multitudinous difference between rural and urban in terms of quality healthcare. There are a number of problems that are present in current healthcare system, one such neglected issue is proper monitoring of medical prescription. Failure in pharmaceutical regulation has led to the non-medical usage of drugs such as opioids, CNS depressants or stimulants. Direct consumer to pharmacy contacts has led to an increase in antibiotic resistance and further impoverishment of the community. The scale of misuse, and in particular overuse, of medications in India is an issue and an increasing concern amongst both government and non-government public health organizations. There’s is poor prescribing practice on the part of physicians as well, common infractions included- not including frequency of dosage on the script, not recording duration and using only brand names on prescriptions. Creation of fake prescription drug has become unchallenging with time, hence there’s a need of a bonafide system for prescription tracking. Healthcare in India has become digitized to some extent but it’s still testing water, one such area of exploration is Blockchain.


Here at Quillhash, we are continuously exploring the real world applications of Blockchain. One of our researches is merging the spectacularity of Blockchain in Healthcare. We have come up with a solution to the misuse of medical prescriptions. Prescription tracking with the help of Blockchain, digitally stored patient data is not being utilized to its potential and results in procedural repetitions incurring both costs and time, a decentralized medical prescription tracking system can help in streamlining the process. As per the National Sample Survey Organisation (NSSO), between 2000–2014, while the GDP per capita based on purchasing power parity (PPP) grew by 121%, the average medical expenditure grew by 176%. That’s almost 60 percentage points more. Reportedly, switching to a digital set-up is projected to save nearly $400 billion annually.

On the blackmarket, an electronic medical health record could be worth hundreds or thousands of dollars, hence storage of electronic medical health record in a centralized system is risky. Our project Prescription tracking is implemented on a Hyperledger Fabric platform designed for use in enterprise contexts. Fabric Blockchain protects the medical data of the patient, only accessible to the approved nodes. Furthermore, in terms of scalability, the hyperledger can handle 1000 transactions per second.

Fabric Blockchain hosts various nodes namely hospitals, pharmacies, e-pharmacies and patients. A web-based app for doctors working in the connected hospital as well as participating pharmacies and e-pharmacies can be deployed. The doctors can upload a patient’s prescription data via the App and pharmacies will be able to access the data only when user permits them in case of e-pharmacies process can be modified. This will prevent the unethical use of medical prescriptions. HIPAA sets federal standards for both privacy and security of protected health information (PHI), patients privacy is utmost priority. HIPAA applies to organizations and individuals who submit claims electronically or digitally like Fabric Blockchain.

Additionally, the long term users of particular medicines, say those for ADHD, can be reminded to get a refill. ADHD medicines are also the ones that are most misused as stimulants, decentralized trustless tracking of drug will reduce the illegal purchase and abuse of the medicine. With the presence of pharmacies and e-pharmacies on Fabric Blockchain, patients can easily find the pharmacy on their location and availability of medicine. Moreover, a crypto wallet can be incorporated into the app, allowing patients to spend tokens via their mobile app to make purchases. As patients have their complete medical history at their disposal, they can easily share or give access to the doctors without the annoyance of repeatedly going through the process of conveying relevant information.


  • Upon a hospital visit, the doctor will upload the patient’s information post-diagnosis. Using Fabric’s private transaction feature, the hash of this data will be added to the blockchain.

  • Keeping in mind that patient data is highly confidential, it will be kept private and access will only be provided on request basis and enabled only for concerned participants. This will be achieved via implementing a solution such as zero-knowledge proof. (In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party can prove to another party that she knows a value x, without conveying any information apart from the fact that she knows the value x )

  • Doctors will be able to see previous medical prescriptions of the patient with their permission and proceed accordingly. This will be especially useful when specialists conducting tests, diagnosis or administering treatment need to know specifics from the patient history like allergies or existing conditions.

  • Data collected through this system can also be utilized for further research and development, without ever compromising patient privacy.


  • As every medical transaction will be recorded on the Blockchain, it will prevent dodgy drug buyers.

  • Eliminate unethical usage of drugs to a large extent.

  • There will be no requirement to physical prescriptions and diagnostic reports.

  • As everything will be recorded on the blockchain, it will reduce the chances of medical frauds.
