Prescrypto: Making sensitive clinical data portable, safe and private

Prescrypto is building RexChain, a healthcare blockchain designed to guarantee portability of sensitive clinical data in a secure and private way. RexChain shifts data ownership to users, empowering them to decide how, and with whom they want to share their information.

With RexChain, your prescriptions will be stored in an encrypted database, which only you - or the people you choose to share them with - can access.
 

To help people receive adequate care, RexChain aims to create a sustainable model that keeps sensitive clinical data safe and private, amidst sharing it amongst healthcare provider.

This ensures that a patient's medical data is not only protected but also remains accurate and accessible to any medical professional or healthcare provider. For example, a patient can seek consultation from and be prescribed a medication by a remote specialist via telemedicine, and these records will also be available to a local physician.

In developing countries, vulnerable populations are in dire need of a tamper-resistant network, which allows participants to control access to medications, care or information. When one goes to a doctor in Mexico, one will probably be prescribed a medication on a piece of paper. This paper can be forged, and its sensitive data be stolen or commercialized for market research without a patient’s consent. Furthermore, since patients are often treated by many rotating doctors, it is difficult to make relevant and accurate clinical information readily available to many doctors and providers.

Blockchain’s novel approach on data ownership and system level governance provides a guarantee to patients that no strangers will view or profit from their clinical information without their consent.

So far, healthcare data has mostly been managed by a centralized database model, where a single administrator has complete access and control over the data stored in private servers. Such technologies are vulnerable to many attack vectors, and often lack little transparency over how data is handled or commercialized. On these two fronts, blockchain offers a novel improvement.

The blockchain protocol offers a new and exciting form of data governance previously impossible to offer.
 

Our blockchain protocol is, by design: encrypted, immutable, decentralized and transparent. This empowers citizens to handle their data themselves, and create adequate channels for expansion that cannot be controlled by stakeholders.
 

FRONTIER TECHNOLOGY & OPEN SOURCE 
 

People often ask us if our team is trustworthy to handle such sensitive clinical information. They don’t need to trust us, they have to trust the code. This is transparency, one of our driving values. We are a passionate expert team of people from many professional backgrounds and nationalities.

Most importantly, we believe that open platforms, which are driven by communities, make the world a better place. It also spurs innovation by providing an open platform that can be used by developers, beginners, experts and enterprise alike.

We were inspired by Bitcoin, impressed by how a group of developers created a technology that surpassed the status quo in many ways, and by cleverly placing it out of the hands of private interests, it became a design paradigm and security standard, which is, in a word, unstoppable.  The solution was clear when we understood how health data could be shared and developed using the same paradigm: harness the benefits of blockchain protocols to solve a real problem with positive impact.
