What is Consortium Blockchain?

A consortium blockchain is a group of multiple financial institutions where each financial institution has its private blockchain. In this blockchain, a pre-selected set of nodes are allowed to control the consensus process. 

What is Consortium Blockchain?

Consortium blockchains are managed and run by a number of organizations or entities. As a permissioned blockchain, users must be asked to join and have authorization before they can access the network. 

• The upkeep of the blockchain network and transaction verification are divided among the participating groups in a consortium blockchain. Instead of being under the control of a singular central authority, the member organizations manage the nodes that verify transactions and keep the blockchain.
• In sectors where multiple organizations must work together on a single platform while keeping control over their data and transactions, this kind of blockchain is frequently used. 
• In general, consortium blockchains provide a balance between decentralization and control, making them appropriate for use cases where a number of well-known and trustworthy parties must collaborate on a common platform.

Features of Consortium Blockchain

The consortium blockchain aids in data transfer, but it is not involved in crypto creation or administration because those tasks are handled by a public blockchain. The greatest place for the consortium is? The groups can collaborate most effectively this way. These are a few of its main characteristics.

1. Data Privacy

Data privacy is supported by fewer nodes in addition to a lighter network burden. Here, unlike private blockchains, only a select few individuals have access to the datasets. The safety and uniqueness of the data in the blocks are exploited by this system. The network's information cannot be changed without the permission of some nodes.

2. Rapid-Fire Transaction

Blockchain consortiums have few users. Because of this, there is less competition for transaction verification among nodes from various groups. Controlled user groups can also speed up the consensus-building process. All of these elements help make deals happen more quickly.

3. Regulations and Rules

Regulations are much more essential to keep the consortium's creative juices flowing because it was specifically created for multiple companies and groups. Nodes must abide by the network's regulations in this situation. By doing so, a team atmosphere is created and efficiency is increased quickly.

4. No Crime was Committed

Because most anonymous users are infamous for clogging up a network's processes, the risk of criminal or illegal activity is completely eliminated when a federated blockchain is connected with a small number of well-known members. This chain's familiarity with one another fosters a system of checks and balances that reduces the likelihood of unlawful activity, making this platform a secure choice for businesses.

5. Zero Probability of 51% Act

Attacks from 51% of users could be disastrous for the blockchain network. A private blockchain is more vulnerable to this problem because multiple groups' members can work together to override or even perform reverse transactions.

How does a Consortium Blockchain Work?

In a consortium blockchain, nodes from various businesses or groups govern the network in a much more private manner. They work together to exchange and modify information in order to preserve workflow, scalability, and accountability. 

• A consortium is a form of blockchain that shares some characteristics with both private and public blockchains, such as scalability and privacy. However, it still manages to stand out by reducing the network burden where a limited number of nodes participate; another example is its voting base system with a small number of well-known participants. Together, these factors enable the network to be both flexible and safe.
• A consortium blockchain is only accessible to selected members, as opposed to a public blockchain, which is open to everyone. 
• In a consortium blockchain, a number of carefully chosen participants run nodes and verify transactions on behalf of the network. 
• Typically, these members are reliable institutions or groups like banks, governments, or corporations.

Depending on the specific implementation, the consensus mechanism in a consortium blockchain can change, but it usually includes some kind of voting or consensus among the members. Using a proof-of-stake (PoS) consensus method, for instance, members who have a stake in the network are in charge of approving transactions.

Benefits of Consortium Blockchain

1. Greater Efficiency

Since the number of nodes in the network is restricted to a trusted set of participants, consortium blockchains may be more efficient than public blockchains. As a result, transaction validation requires less computational capacity, resulting in quicker transaction times and cheaper fees.

2. Enhanced Security

 Because a small group of well-known and dependable members controls consortium blockchains, they are more secure than public blockchains. Because of this, it is more difficult for bad actors to manipulate the network or carry out fraudulent operations.

3. Shared Costs

keeping a consortium blockchain can be less expensive than building and keeping a private blockchain network because the costs are split among its members.

4. Better Data Privacy

 Because a smaller group of reputable members can access the network, consortium blockchains offer greater data privacy than public blockchains. Because of this, it is better suited for commercial use cases where data privacy is crucial.

5. More Control

In a collaborative blockchain, each participant can influence network administration and transaction validation. As a result, there may be better governance and decision-making because everyone has an interest in the network's success.

6. Scalability
Consortium blockchains can scale more efficiently than public blockchains because the number of participants is restricted. This means that transaction processing capacity can be increased without affecting the performance of the network.7. 

7. Customizable Governance
In a consortium blockchain, participants can customize the governance model to suit their specific needs. This allows for greater flexibility in decision-making and helps to ensure that the network is aligned with the participants' interests.

8. Interoperability
Consortium blockchains can be designed to interoperate with other blockchain networks or traditional systems. This can help to streamline business processes and improve efficiency.

9. Reduced Regulatory Burden
Because consortium blockchains are restricted to a trusted group of participants, regulatory compliance can be easier to manage. This can help to reduce the regulatory burden on organizations and lower the cost of compliance.

10. Collaborative Innovation
Consortium blockchains can be used to foster collaborative innovation among participants. By sharing resources and expertise, participants can develop new solutions and applications that benefit the entire network.
 

Limitations of Consortium Blockchain

• A consortium's centralized network architecture makes it easier for ruthless players to flout the norms of the network.
• Due to the larger network of users, it is difficult to upgrade this platform because each network user must give their consent.
• The consortium's efficacy is still being refined.
• A company among the businesses could promote the growth of the industry. The likelihood of such a company is lower in this area, though.
• It takes a lot of work to build such a platform, and various groups must come together to discuss communication protocols.  
• Limited Decentralization :
  While consortium blockchains are more decentralized than traditional centralized systems, they still rely on a group of trusted participants to manage the network. This limited decentralization can be a drawback for organizations seeking a fully decentralized solution.
• Potential for Conflict of Interest :
  Because consortium blockchains are governed by a group of participants, there is a potential for conflict of interest. Participants may prioritize their own interests over the interests of the network, leading to governance issues and potential disputes.
• Limited Transparency :
  Consortium blockchains offer less transparency than public blockchains. Because the network is restricted to a group of participants, it can be difficult for outside parties to verify the accuracy of data on the network.
• Risk of Network Fragmentation :
  If a member of a consortium blockchain leaves the network or fails to comply with the network's rules, there is a risk of network fragmentation. This can compromise the security and integrity of the network, particularly if the departing member had a significant role in the network's governance or validation process.
• Governance Challenges :
  Consortium blockchains require a well-designed governance structure to ensure that all participants are aligned with the network's goals and interests. Achieving this can be challenging, particularly if the participants have different priorities or conflicting interests.
