What Are Hybrid Blockchains

Content provided by various contributors. DYOR.

A hybrid blockchain is a type of blockchain that combines the features of both public and private blockchains. Depending on the user’s needs, it allows public and private access to the blockchain network. For example, in a hybrid blockchain, some nodes may be designated as “public” nodes accessible to anyone on the network.

In contrast, other nodes may be designated as “private” and only accessible to a specific group of users. This allows for a balance of security and decentralization and the ability to handle sensitive transactions or data.

The hybrid blockchain can be set up in different ways, for example, with a public blockchain that allows private transactions via zk-snarks.

Hybrid Blockchain Benefits and Drawbacks

Hybrid blockchain has several benefits:

  1. Increased security: By combining the features of public and private blockchains, a hybrid blockchain can offer increased security for sensitive transactions or data.
  2. Flexibility: A hybrid blockchain allows public and private access to the blockchain network, depending on the user’s needs. This allows for a balance of security and decentralization.
  3. Scalability: The private side of a hybrid blockchain can handle a higher number of transactions per second (TPS) than a public blockchain, which can improve scalability.
  4. Interoperability: It allows for the integration of different blockchain systems, which can enable cross-chain communication and the exchange of assets between different blockchains.

However, it also has some drawbacks:

  1. Complexity: Setting up and maintaining a hybrid blockchain can be more complex than a public or private blockchain.
  2. Centralization: The private side of a hybrid blockchain may be controlled by a central authority, which can reduce decentralization.
  3. Cost: Setting up a hybrid blockchain can be more expensive than a public or private blockchain.
  4. Trust: Establishing trust in a hybrid blockchain system may be challenging because a central authority may control the private side.

The Purpose of Hybrid Blockchains

Since hybrid blockchains combine the benefits of public and private blockchains, it allows for a balance of security and decentralization. It can be used for different purposes, such as:

  1. Supply Chain Management: A hybrid blockchain can track the movement of goods through a supply chain while keeping sensitive information private.
  2. Financial Services: A hybrid blockchain can be used for financial services, such as digital payments and securities trading while keeping sensitive financial data private.
  3. Healthcare: A hybrid blockchain can store and share patient information while keeping sensitive data private and secure.
  4. Identity Verification: A hybrid blockchain can store and verify identity information while keeping sensitive data private.
  5. Public Administration: A hybrid blockchain can store and share public data, such as voting records, while keeping sensitive data private.
  6. Gaming: A hybrid blockchain can be used to handle in-game assets while also keeping sensitive information private.
