Difference Between Hybrid Blockchain And Consortium Blockchain

Blockchain technology, as an intriguing and fundamental innovation in the field of information technology, has gradually gained global attention. It is divided into four types, but in the implementation of this powerful technology, organizations and companies do not necessarily choose a specific type of blockchain.

This is because each type of blockchain has its own characteristics and different applications, and organizations select them based on their individual needs.

Blockchains can be classified into two main categories based on access levels, public and private blockchains. In public blockchains, anyone can access the network and perform transactions, while in private blockchains, access is restricted to a specific group of individuals or organizations.

In addition to these two main categories, there are two other types of blockchains that combine features of both public and private blockchains. These are known as hybrid blockchain and consortium blockchain. In this article, we will delve into the difference between hybrid blockchain and consortium blockchain.

Blockchain

Blockchain

Blockchain is a distributed ledger comprised of a continuous chain of blocks. Each block stores information about transactions or data using encryption and is connected to the previous block.

This system is widely used in various fields such as digital currencies like Bitcoin and many other applications due to its security, scalability, and decentralization, eliminating the need for central intermediaries. Blockchain securely stores and makes transactions unchangeable, preventing any attempts at alteration or network attacks.

Hybrid Blockchain

Hybrid blockchains are a type of blockchain network that combines features of both public and private blockchains. It’s like a private network within a public network. In this system, a part of the blockchain is public, allowing free access to all participants, while other parts are private, restricted to a selected group of network participants.

This blockchain network is controlled by a central authority, determining who can access the data stored in the blockchain and which data is publicly accessible or restricted to specific individuals.

Due to this feature of hybrid blockchains, it assists managers and organizations in precisely controlling which information should be publicly accessible and which information requires enhanced protection. This not only enhances transparency in transactions but also ensures the safeguarding of sensitive information against unauthorized access.

In a hybrid blockchain system, the process of adding a block to the hybrid blockchain is executed as follows:

a private node creates a new transaction containing various information, including the amount, date, and time of the transaction.

Then, the private node adds this transaction to a block, which includes the hash of the previous block, the hash of the new transaction, and other relevant information. After creating the block, the private node sends it to other private nodes in the network.

Now, public nodes in the network examine the new block, ensuring that all information related to the entered transaction is accurate. Upon valid confirmation of the new block, public nodes add it to the main blockchain.

This process ensures that private transactions are first validated within the private network and then added to the blockchain with the approval of public nodes,creating a synchronized and secure blockchain with limited transparency. Dragonchain is an example of a hybrid blockchain.

Advantages of Hybrid Blockchain

  • Closed Ecosystem: Hybrid blockchains operate within a closed ecosystem, preserving and verifying private information within the network. This allows users to confidently use sensitive data while keeping it inaccessible to individuals outside the network.
  • Flexibility: Hybrid blockchains exhibit high flexibility, enabling customization of the ledger based on the specific needs and conditions of the network. This crucial feature empowers organizations to adapt to their own characteristics.
  • Privacy Protection and Establishing Connections: In addition to ensuring user privacy, hybrid blockchains facilitate effective communication with third parties, especially network stakeholders and the general public. These connections enable individuals to participate in various network matters and exercise more oversight.
  • Enhanced Scalability: Hybrid blockchains offer better scalability compared to public blockchains at an acceptable level. This capability allows the network to confirm transactions with fewer nodes, leading to reduced transaction fees.

Disadvantages of Hybrid Blockchain

  • Lack of Transparency: Due to privacy preservation, hybrid blockchains lack transparency, meaning there is no open access to stored information in the network. In some cases, there may be a need for increased openness to information.
  • Lack of Specific Rewards: Unlike public blockchains that provide rewards to miners, hybrid blockchains do not offer specific rewards to participants. This may discourage some individuals from optimal network participation.
  • Slow Upgrade Speed: Upgrading and expanding hybrid blockchains pose a significant challenge. Some of these networks may progress at a slower speed compared to public blockchains, potentially deterring users from optimal utilization.

Consortium Blockchain

Consortium Blockchain

Consortium blockchain is a type of blockchain that operates as a non-public platform managed by a consortium organization, with a specified number of chosen members or partners participating. Unlike private blockchains managed by an independent institution, consortium blockchains are more decentralized and provide higher security.

In this type of blockchain, membership is granted to specific groups or individuals rather than a central authority. Access and participation in the network are limited and assigned to selected members. While this provides high security and quicker control, establishing consortia can be challenging, requiring collaboration among various businesses.

Consortium blockchains use a voting-based model to confirm transactions and blocks. In this system, each node is authorized to record transactions, but adding a block requires confirmation from other nodes. This feature allows the system to be more exposed to innovation, resulting in improved performance.

One prominent example of the use of consortium blockchains in the financial industry is the Corda project developed by R3. Corda is an open-source blockchain platform designed specifically for the financial industry, leveraging consortium blockchain technology.

In the Corda network, banks, insurance companies, and other financial institutions are recognized as participating members, allowing them to conduct financial transactions without the need for central intermediaries.

Advantages of Consortium Blockchain

  • Security: Consortium blockchain, by providing access only to network participants, offers enhanced protection for information. This results in increased security levels and prevention of unauthorized access to sensitive data.
  • Control:
    In consortium blockchain, network control is exercised by a specific group of reputable participants. This ensures that decision-making occurs in a collaborative and interactive manner.
  • Verification: The number of participants in consortium blockchain is defined and verified. A valid identity verification of participants helps prevent security risks and ensures the preservation of privacy.
  • Transaction Fee: In comparison to other blockchains, consortium blockchain does not impose costs such as transaction fees on participants. This feature attracts more participants to join.

Disadvantages of Consortium Blockchain

  • Complexity in Consortium Establishment: Forming a consortium and reaching agreements among members on rules and regulations can create challenges and complicate the development process.
  • Slow Upgrade Speed: With an increase in the number of participants, the process of upgrading the network protocol may encounter difficulties, leading to reduced transaction speed.
  • Need for Coordination: The development of consortium blockchains relies on collaboration among network participants. Lack of agreement among them can hinder the development process and network progress.

Difference Between Hybrid Blockchain and Consortium Blockchain

Hybrid Blockchain and Consortium Blockchain both utilize a combination of private and public nodes. However, there are Difference between Hybrid Blockchain and Consortium Blockchain.

Network Control Approach
One of the key difference between hybrid blockchain and consortium blockchain lies in how the network is controlled. In a hybrid blockchain, private nodes are responsible for creating and validating new transactions, and after creation, they confirm the transactions.

Public nodes, in this case, are responsible for reviewing and adding new blocks to the blockchain. This model allows private nodes to quickly create and confirm transactions, while public nodes focus on validation.

In contrast, in Consortium Blockchain, consortium nodes are responsible for creating and validating transactions. These nodes can be controlled by an organization or a group of organizations. in this case, network control is in the hands of a selected group of individuals in a limited and specific manner.

Access to Information

Another difference between Hybrid Blockchain and Consortium Blockchain is the level of access to information. In Hybrid Blockchain, all network nodes can access public information, but only private nodes can access sensitive information.

In Consortium Blockchain, only consortium nodes can access network information. This means that all participants in the network are verified and valid members, each having access only to the data necessary for their activities. This ensures high privacy and specific control for network members.

Scalability

The difference between hybrid blockchain and consortium blockchain in terms of scalability is significant. In hybrid blockchain, by leveraging private nodes and independently processing transactions in parallel through these private nodes, it achieves higher scalability.

This capability results in increased transaction execution speed and reduced latency. In other words, hybrid blockchain provides optimal performance in situations where high processing power and transaction speed are required.

On the other hand, Consortium Blockchain faces limitations in scalability due to a predetermined and limited number of network nodes. This restriction may pose challenges in handling a high volume of transactions, leading to increased response time and impacting the overall network performance.

How To Choose The Right Blockchain Technology

Selecting the right blockchain for your needs is a fundamental challenge that requires a precise understanding of your goals and criteria. Firstly, you must define your objectives and accurately determine your requirements.

For conducting financial transactions on a public blockchain with tradable tokens, options like Bitcoin or Ethereum might be suitable. However, if you seek to preserve data privacy and participate in a private network, private blockchains such as Hyperledger Fabric or Corda could be noteworthy choices.

Moreover, if you require more flexibility and wish to benefit simultaneously from the features of both public and private blockchains, hybrid blockchain and Consortium Blockchain could also be suitable options. These options have their own specific features and advantages, providing the capability to adapt to your diverse needs.

Conclusion

After examining the difference between hybrid blockchain and consortium blockchain, it becomes evident that the choice between the two depends on the specific needs and goals of each organization or group. Hybrid blockchain, by combining the features of both public and private blockchains, allows for the creation of a flexible environment capable of adapting to the diverse needs of companies. This flexibility enables companies to benefit from the unique features of both types of blockchains.

On the other hand, consortium blockchain, by providing more precise control and restricting access to information, especially in limited collaboration scenarios and areas such as the financial industry, is an effective option for ensuring security and data control. Therefore, the decision to choose between hybrid blockchain and consortium blockchain requires a thorough analysis of the needs and requirements of each organization to make the best choice based on their specific and unique conditions.
