Types of Blockchain in the Healthcare Industry 

There isn't a single, specific "type" of blockchain for healthcare. Instead, there are different  permission models  used in blockchain networks, and these models determine who can participate and contribute data to the ledger Here's a breakdown of the most common permission models used in healthcare blockchain:

1. Public Blockchain:

Anyone is allowed to participate in a public blockchain, which is a decentralized network. There is full transparency and everyone in the network can see every transaction.

Use Cases in Healthcare: Public blockchains can be used for applications requiring high transparency and security, such as public health data repositories, patient consent management, and decentralized health information exchanges.

2. Private Blockchain:

Blockchains that are private are restricted networks so that only authorized participants can join and access them. It provides greater control and privacy than public blockchains.

Use Cases in Healthcare: Private blockchains are suitable for internal hospital networks, secure patient data management, and healthcare provider credentialing systems. They allow healthcare organizations to maintain control over sensitive data while ensuring its integrity.

3. Consortium Blockchain:

As opposed to centralized networks, consortium blockchains are decentralized networks operated by many organizations. Combining public and private blockchains, it offers the benefits of both worlds.

Use Cases in Healthcare: Consortium blockchains are ideal for collaborative efforts among multiple healthcare institutions, such as shared patient records, clinical trial data sharing, and pharmaceutical supply chain management. They facilitate cooperation while ensuring data privacy and security.

4. Hybrid Blockchain:

A hybrid blockchain combines elements of both public and private blockchains, offering flexibility in determining which data is public and which is private.

Use Cases in Healthcare: Hybrid blockchains can be used in scenarios where some healthcare data needs to be publicly accessible for transparency (e.g., drug traceability) while other data must remain confidential (e.g., patient health records).

5. Permissioned Blockchain:

A permissioned blockchain restricts access to the network to a specific set of participants. These participants have designated roles and permissions within the blockchain.

Use Cases in Healthcare: Permissioned blockchains are useful for applications requiring strict access control, such as insurance claim processing, patient data sharing between trusted entities, and regulatory compliance tracking.

6. Federated Blockchain:

A federated blockchain is similar to a consortium blockchain but typically involves a more structured governance model where a few preselected nodes control the network.

Use Cases in Healthcare: Federated blockchains are well suited for regulatory bodies and healthcare organizations working together to maintain and audit medical records, manage drug supply chains, and oversee clinical trial data.

7. Sidechains:

Sidechains are separate blockchains that are linked to a main blockchain, allowing assets and data to move between them. They enable scalability and specialized functionality.

Use Cases in Healthcare: Sidechains can be used to manage specific healthcare applications, such as handling large scale genomic data, while maintaining a secure link to the main patient data blockchain.

Blockchain Equipped healthcare organizations can choose the most appropriate blockchain framework to address their specific needs, enhancing data security, interoperability, and operational efficiency in the healthcare industry.
