Blockchain Type

The most suitable blockchain type for personal medical data would be a special blockchain. According to the blockchain decision model, a blockchain can be used in a scenario where multiple parties that do not trust each other need to interact and exchange shared data but do not want to involve a third party (TTP).

Let's examine the blockchain in health according to the blockchain decision model:

Does the classic database meet the needs?

Databases are based on a centralized system. But blockchain works with a decentralized system. In the central environment, data is an open target and is not as resistant to attacks as blockchain. Therefore, the classical database does not meet the requirements.

Is there more than one participant? Does it need to update?

There are many stakeholders in the health sector. Each stakeholder needs to access, update, and exchange data to accomplish a set of tasks or to achieve what they want. These processes need to be reliable and controlled.

Do stakeholders trust a third party?

In the field of health, each stakeholder is responsible for processing confidential and sensitive data as a result of their work. In this context, health information and health provider can face to face with cyber-attacks, fraud, and malicious attacks. The blockchain can handle all transactions without the transparency of data sharing and the need for a third-party environment of semi-trust.

Is there a need for data privacy?

Since the blockchain creates immutable records and is very strong against attacks, data security needs to be at the highest level in the healthcare field, therefore due to its structure, data privacy will be stored in a very secure environment.

Is there any need for control over who can make changes?

In the blockchain system that will be created in the health field, it is necessary to access the ledger to be shared and the nodes that write to the ledger.

The blockchain type that will operate in the field of health must be Special Blockchain.
