PHB Ecosystem




dClinic’s Private Healthcare Blockchain (PHB) supports global secure health data exchange protocol standards. PHB ensures secure management, handling and tracking of a consumer’s Healthcare Data. PHB is a dedicated and purpose built healthcare blockchain and is NOT a repurposed financial transactional based blockchain.

• Consumers and care givers, as part of care teams and with the right consent, can truly monitor and analyse their healthcare data. Finally, healthcare data can be generated, accessed and updated as part of a true healthcare eco-system.

• Healthcare App developers can use this dedicated Healthcare Blockchain to build their own decentralised Healthcare Apps, so consumers and care givers can use these Apps securely and know their sensitive healthcare data is correct, safe and importantly, interoperable.

• PHB properly handles highly fractal clinical data in a way that is standards based, allowing external systems to understand the data the same way each and every time. Most importantly, the PHB handles big healthcare data efficiently and allows for fast transactions.

• PHB, by the very fact that it promotes healthcare eco-system building, also promotes Care Planning (by an ever-changing care team based on a consumer’s current and past situation) as a fundamental model for providing proper care that is truly outcomes based. The consumer, who is sometimes a patient, is at the centre of their care.

• Healthcare data is managed (consented) in cooperation between consumers and care givers, so their data can be utilised to help drive positive healthcare outcomes which otherwise would be very difficult to achieve if their data existed in disparate silos.


PHB Architecture




The PHB is a purpose-built healthcare blockchain that is based on a standards based clinical modeling framework. Clinical data is fractal, complex and big. The only way any blockchain can properly manage and make use of this type of data is to separate and treat the clinical data independently of the transaction blocks themselves, yet have the transaction blocks create the audit trail for all add and updates to the clinical information. Using a standards based, dedicated clinical framework also allows us to manage geography driven regulatory and consent models. Extending the framework allows smart contracts, based on conditions, to also be part of the clinical decision-making process related to the consumer, who is sometimes a patient. AI can also be used to provide additional smart decision support and analysis.


Now we can truly store and manage big data in a healthcare blockchain even if the data relates to pathology, other image data, insurance claims, clinical trials and the more regular clinical based (big data) transactions that most of us will encounter in our lifetimes. Most importantly, dApp builders can leverage the PHB to build dApps that put the patient at the centre of their healthcare team. These are the innovations that drive endeavours to achieve positive healthcare outcomes and true cost savings in healthcare globally.

Technology (Use-Cases)


PHB applications within the life sciences and healthcare sector.

Storage and access to medical records

Access could be controlled and subject to levels of access. Blockchain would also prevent fragmented patient data by allowing all healthcare providers to access a patient’s data once consent has been given.

Patient management of their preferences

Patients could update their preferences eg organ transplant or the need for an interpreter.

Data for clinical trials

Blockchain would allow for time-stamped results, prevent alteration of data and ensure that accuracy of results.


Intellectual property evidence

Blockchain would allow research and development companies to prove the date and creation of their intellectual property and would give immutable evidence for patents and/or infringement claims.

Supply chain

Blockchain could also allow each batch of medicines to be time-stamped with a serial number and allow said batch to be easily tracked during each of its movements, so that each transaction is documented in the blockchain. This would help fight the counterfeiting of drugs and assist the ease of product recalls.

Medical negligence claims

If all treatment details and medical decisions are captured in a blockchain it could provide useful evidence in medical negligence claims.

Use cases for PHB in digital life sciences


The application for the PHB in the life sciences bridges the gap between patient data and the digital life sciences industry, integrating two currently siloed areas.
