Why DoctorsChain

Problems & Solutions

Health information system (HIS) refers to the scheme managing health data of individuals. HIS is considered as the most critical tool to give a patient accurate and appropriate medical solution at the right time.

The present HIS, however, is extremely fragmented since a clinic merely records the health information of a patient and is reluctant to share its own data with other institutions. It is inevitable that you waste enormous amount of money and time for repetitive medical tests in the current closed system like this.

The primary damage the locked HIS brings is that you may miss the critical chances to treat your disease the right way and at the right time.

DoctorsChain is constructed to solve the challenges the current health data system faces. It is a platform that uses the decentralized technologies of blockchain and smart contracts which can make health information exchanges more efficient.

Bockchain Hospital

Blockchain hospital uses DrC technology that personal Health records are managed by blockchain and DrC token is used for all payment.

We are supposed to expand DrC system to help hospitals around the world to switch to blockchain hospitals easily and have a plan to establish DrC hospitals worldwide.


In DrC Hospital in Vietnam, all treatment costs are paid by DrC.

The PHR is stored in a blockchain and will be used easily for post-treatment anywhere in the world.

In other words, after a Korean doctor has performed plastic surgery in Vietnam, the patients who get operation in Vietnam can come to Korea and continue treatment.

DrC Hospital will open a medical video lecture system in DrC Community to help doctors improve their medical skills.

Frequently Asked Questions

Find more information about the DoctorsChain Echo System. - The incentivized, blockchain-based, personal health record platform.

DoctorsChain is basically based on PHR (Personal Health Record) which can also be named 'Personal Health log' . The PHR is a tool that you can use to collect, track and share past and current information about your health or the health of someone in your care. Your PHR can give medical care providers more insight into your personal health story. PHR is different from medical records which contain information about your health compiled and maintained by each of your healthcare providers. A PHR, however, is information about your health compiled and maintained by you.
DRC solves security problems through Hyperledger Fabric technology. Hyperledger Fabric is the system that all access control decisions are based upon the user’s identity attributes. The sensitive data is only shared with those members are allowed to have access to it. Hyperledger Fabric is about having separate ledgers or channels each distributed ledger in the network lives only within the context of a channel. Thus, total data confidentiality across organizations that don’t need to share any data can be achieved by allocating these organizations to separate channels.
The users who donate their medical data can get financial reward through the deals making in Marketplace and they are also able to get special medical care when they need it. The health institutions such as a hospital, a medical laboratory and a pharmaceutical firm can get big healthcare data to cure diseases or work on medical experiments.
