Health care records could be stored on the blockchain to provide quick and tamper-proof information. It can also contribute to medical research by giving medical professionals access to more data. 


Healthcare

The 2009 Health Information Technology for Economic and Clinical Health Act (HITECH), part of the American Recovery and Reinvestment Act, brought almost $30 billion in funds to incentivize Electronic Health Record (EHR). The shift towards patient-centered interoperability is an important trend that has the potential to lay new groundwork for data sharing in healthcare. Blockchain is one technology that could have a role in improving interoperability.
