Blockchain technology has taken the world by storm, and it has become a mainstream technology . Various types of blockchain have been developed to cater to different needs. Out of all, three types are the most commonly utilized ones: Public, private, and consortium blockchain.

Public blockchain is the most open and transparent blockchain type that is accessible to anyone who wants to participate. This blockchain operates through a proof-of-work consensus mechanism, making it tamper-proof and secure. On the other hand, private blockchain is accessible only to authorized participants who have permission to access and modify the blockchain. Private blockchain is faster and more scalable compared to the public blockchain.

Consortium blockchain, on the other hand, is when multiple organizations or businesses operate a blockchain together as a team. This type of blockchain is ideal for collaborative work on a shared ledger without relying on a centralized institution. Federated blockchain is a type of consortium blockchain that operates with a higher level of trust and security. Non-equity consortium blockchain network gives every organization equal power, whereas in equity consortium blockchain, the level of decision-making power varies depending on the participating organization's ownership level.

In conclusion, choosing the right blockchain type depends on the use case, and each blockchain type has its benefits and drawbacks. As technology continues to advance, we can expect more innovative blockchain types to emerge in the future.

Public Blockchain

Public blockchain is a revolutionary concept in the world of blockchain technology . It is also known as an open blockchain as it is open for all to join and participate without permission. In the public blockchain, anyone can not only read, but also can validate and write on the ledger, which makes it truly decentralized.

One of the prominent features of the public blockchain is its tamper-proof and secure nature. All the transactions are verified and approved by users through a consensus mechanism called Proof-of-Work (PoW). The PoW not only approves transactions but also ensures the authenticity of the transactions by solving complex mathematical problems. Once a transaction is approved, it becomes immutable, and it cannot be altered or deleted.

Bitcoin, the world's first cryptocurrency, is a perfect example of the public blockchain. It allows for secure, peer-to-peer transactions without the need for intermediaries. It has proven to be an excellent way to exchange value without central authorities and is used by millions of users around the globe.

Although the public blockchain is highly secure and transparent, it is slower and less scalable compared to other blockchain types. Nevertheless, it is still a go-to option for those who prioritize transparency and decentralization over speed and efficiency.

Private Blockchain

Typically used by businesses and organizations with shared interests, the main advantage of private blockchain is that it is faster and more scalable compared to a public blockchain.

The use of a private blockchain allows companies to have complete control over their data and ensures that only authorized parties have access to it. This makes it ideal for business-to-business transactions where the confidentiality and integrity of data is of utmost importance.

Private blockchains can be implemented as either a permissioned or permissionless blockchain. A permissioned blockchain is where a set of trusted nodes are authorized to validate and verify transactions within the blockchain network, while a permissionless blockchain provides access to anyone who wants to join the network.

Another type of private blockchain is an enterprise blockchain. This is a private blockchain that is utilized by a group of enterprises for conducting internal transactions. The blockchain provides a secure and transparent environment for these transactions while allowing companies to share relevant information with one another.

Overall, private blockchain is a popular option for businesses and organizations that require complete control over their data and want to ensure that it is only accessible to authorized parties. Through the use of private blockchain, businesses and organizations can conduct transactions quickly and securely, without the need for a centralized intermediary.

Permissioned Private Blockchain

A permissioned private blockchain restricts access to the blockchain to a defined group that participates in the network. The nodes in the network are authorized and trusted, and they are responsible for validating and verifying transactions. This type of blockchain is designed for businesses that require enhanced privacy and control over their transactions.

The beauty of permissioned private blockchain is that it offers a higher level of privacy and security as the nodes must be authenticated before they participate in the network. With permissioned private blockchain, the organizations that are involved have more control over the governance of the network, and they can define the rules that govern the transactions.

Permissioned private blockchain has numerous use cases, especially in industries that require higher privacy and control over transactions. For instance, supply chain management, healthcare, and finance are ideal for permissioned private blockchain.

A hybrid blockchain can be challenging to develop and maintain, as it requires a high level of technical expertise. However, its unique capabilities and benefits make it an attractive solution for companies and organizations that require a combination of privacy, security, and transparency.

Consortium Blockchain

A consortium blockchain is a collaborative effort among multiple organizations or businesses to operate a blockchain without relying on a centralized institution. In this type of blockchain, each participant has a say in the management and validation of the shared ledger.

A consortium blockchain is ideal for scenarios where multiple parties need to collaborate on a shared ledger, but cannot trust a single entity to manage it. For instance, the financial industry could use consortium blockchains for faster and more secure clearing and settlement processes.

Unlike public blockchains, consortium blockchains are permissioned, which means that only authorized participants can access and contribute to the network. This makes them more secure and private than public blockchains, while still retaining the benefits of decentralization and immutability.

One common type of consortium blockchain is a federated blockchain, which operates similarly to a consortium but with a higher level of trust and security. In this type of blockchain, specific nodes are responsible for maintaining the network, and they can be changed as needed.

Another variation of a consortium blockchain is a non-equity consortium, where all participating organizations have equal decision-making power and no organization has more authority than the others. In contrast, an equity consortium blockchain allows participating organizations to have different levels of ownership in the network.

Overall, consortium blockchains are an ideal choice for collaborative work on a shared ledger without relying on a centralized institution. As blockchain technology evolves, we can expect to see more innovative uses for consortium blockchains in various industries and applications.

Federated Blockchain

A federated blockchain, as the name suggests, is a type of blockchain that involves a group of organizations working together as a team. This type of blockchain operates much like a consortium blockchain, but with an increased level of security and trust.

Unlike a consortium blockchain, a federated blockchain is run by specific nodes that have been authorized to maintain the blockchain. These nodes are often chosen based on their trustworthiness, expertise, and track record. They are also responsible for verifying and validating transactions on the blockchain.

One of the key benefits of a federated blockchain is that the nodes can be changed as and when required. This allows for greater flexibility in terms of who has access to the blockchain and who is responsible for maintaining it.

In addition to enhanced security and flexibility, a federated blockchain can also offer improved transaction speeds and scalability. This is because the network is managed by a smaller group of trusted nodes, rather than a large and decentralized network of nodes.

A good example of a federated blockchain is the Hyperledger project, which is a collaborative effort between different organizations to develop a suite of blockchain technologies for enterprise use.

In conclusion, a federated blockchain is a type of blockchain that offers increased security, flexibility, and scalability. It operates like a consortium blockchain but with specific nodes that can be changed as necessary. As blockchain technology continues to evolve, we can expect to see more use cases for federated blockchains in the future.

Non-equity Consortium Blockchain

A non-equity consortium blockchain is a type of blockchain network that ensures that every organization involved in the consortium has equal decision-making power. This means that no organization can dictate the direction of the network without the approval of all other participants.

This type of blockchain network ensures that all participants have an equal say in the direction of the consortium. Every organization has an equal voice in the decision-making process and must work together to achieve the goals of the consortium. The transparent nature of the blockchain promotes trust and collaboration among participants.

Although non-equity consortium blockchains provide a great deal of transparency and fairness, they do come with their own set of challenges. Since every entity has equal decision-making power, it can be difficult to reach a decision and move forward with the project. In addition, the lack of a leader or central authority can slow down decision-making and implementation.

Despite its challenges, non-equity consortium blockchains provide a level of transparency and fairness that is hard to match. This makes it an ideal option for collaborations that require equal decision-making power and transparency.

Equity Consortium Blockchain

Equity consortium blockchain is a type of consortium blockchain where the participating organizations have different levels of ownership in the network. In this type of blockchain, the ownership of nodes is divided among consortium members based on the amount of capital contributed to the blockchain. The more a participant invests in the blockchain, the greater their ownership stake.

The equity consortium blockchain is suitable for situations where the participating organizations require different levels of access and control over the shared ledger. For example, a consortium of banks may create an equity consortium blockchain where banks that invest more capital will have more control over the network and its governance decisions.

Equity consortium blockchain has several advantages over equity-free consortium blockchain. Since ownership is based on investment, it creates an incentive for organizations to contribute more capital to the network. It also promotes transparency and accountability among consortium members regarding their network contributions. Furthermore, it can also attract new members who are interested in becoming part-owners by investing capital in the blockchain.

The equity consortium blockchain also has several disadvantages. This type of blockchain is vulnerable to centralization if a few participants invest significant amounts of capital, leaving other members with little or no influence over the network. Additionally, conflicts can arise between consortium members with different levels of ownership when making decisions about the network's direction.

In conclusion, depending on the use case, the equity consortium blockchain may be the right type for your organization when considering the advantages and disadvantages of this type of blockchain. It's important to weigh the benefits and potential drawbacks of each type of blockchain network before choosing which one to use.

Conclusion
