[And i read the white paper ,but I coudn't find a wrong with that , tell me if you found any issue]

Unlike traditional EHR, which is expensive, insecure and in-efficient, the Veda Health Portal strives to use a blockchain-based  model  for  maintaining  its  data  distribution  and  ownership  access  and  granting  robust  access to a patient's medical record. Veda will utilize a consortium blockchain technology called Hyperledger, which  helps  it  link  directly  to  the  EHR.  Patients  will  be  able  to  choose  to  grant  different  levels  of  access  to  physicians  regardless  of  the  physician's  EHR.  Moreover,  a  physician  will  add  data  in  the  blockchain,  which  is  then mirrored in the EHR in real-time, allowing the original record to remain up-to-date. Furthermore, the Veda Health Portal will also enable other dApp developers and existing EHR vendors to connect to its blockchain network. This will eliminate the need for providers to duplicate entries in their original EHRs  and  the  blockchain  by  linking  all  records  through  one  data  entry  point.  Additionally,  the  blockchain  technology will give patients a key to access their own data

The blockchain technology, called Hyperledger, links directly to the EHR that includes a patient portal. Patients can choose to grant different levels of access to physicians regardless of the physician's EHR. The physician can add data in the blockchain, which is then mirrored in the EHR in real-time, allowing the original record to remain up-to-date.

MTBC is also allowing other EHR vendors to connect to the blockchain. This will eliminate the need for providers to duplicate entries in their original EHRs and in the blockchain by linking all records through one data entry point. Additionally, the blockchain technology will give patients a key to access their own data.
