Problem:

Basic health information of a person such as Blood group, heart/diabetic problem info, order donor status are quickly needed when a person is in medical emergency. Delay in finding these info may cost a life. In emergency need of initial funds is crucial.

Solution:

Using hyperledger blockchain, We store a person's both public health information & private medical history. We allow hospitals/labs to issue blood donor rebates as ERC20 based HEAL Tokens. And they will accept HEAL tokens as mode of payment.
