Types of Blockchain Networks: Concerns regarding data privacy, decentralization, and openness have been profoundly altered by blockchain technology. Blockchain is essentially a distributed ledger that records transactions across various computers in a secure and impossible way to mess with. The truth is, though, that blockchain networks vary greatly. Types of Blockchain Networks Different kinds of blockchain networks have different features, benefits, and drawbacks, as determined by the use case.
Types of Blockchain Networks
There are four distinct kinds of blockchain networks: public, or open and decentralized, blockchains; private, or limited to a select group of users; consortium, or managed by multiple organizations; and hybrid, or combining the best of both worlds, blockchains.
Public Blockchain
A public blockchain is a decentralized, permissionless network where anyone can join and participate in the consensus process, validating transactions and maintaining the ledger. Public blockchains are designed to be fully transparent, allowing anyone to view transactions and participate in the network’s activities. This makes them highly secure due to the distributed nature of the network but also potentially slower due to the larger number of participants.
Bitcoin: Bitcoin is the most well-known public blockchain. It allows anyone to participate in mining (transaction validation) and access the ledger to see all transactions. Bitcoin’s decentralized nature ensures security through its consensus algorithm, Proof of Work (PoW). However, this also leads to slower transaction times and high energy consumption, particularly during mining.
Ethereum: Ethereum is another major public blockchain that serves as a cryptocurrency platform and supports smart contracts. Like Bitcoin, Ethereum uses PoW but has plans to transition to a Proof of Stake (PoS) model to improve efficiency and reduce energy consumption.
Private Blockchain
A private blockchain is a permissioned network where only selected individuals or organizations can participate. A single entity or a consortium typically controls these networks. Private blockchains are more centralized than public ones, and their use is often confined to enterprise-level applications that require privacy, speed, and control over the participants.
Hyperledger Fabric: The Linux Foundation developed Hyperledger Fabric, a private blockchain designed for enterprise use. It allows organizations to create customized blockchain applications and grant specific access permissions to participants. Hyperledger Fabric is used in industries like supply chain management and finance, where privacy and control are paramount.
Corda: Corda is a private blockchain platform developed by R3, specifically designed for financial institutions. It allows banks and other financial entities to securely, efficiently, and privately share data while maintaining strict control over transaction validation.
Consortium Blockchain
A consortium blockchain is a hybrid between public and private blockchains. In this model, multiple organizations form a network where only approved participants can validate transactions. Unlike private blockchains, where a single entity has control, consortium blockchains distribute decision-making power among several organizations, ensuring more decentralized control while maintaining some level of privacy.
Quorum: Quorum is an enterprise-focused version of Ethereum developed by J.P. Morgan. It is a consortium blockchain that allows multiple financial institutions to participate while ensuring that sensitive transaction details remain private. Quorum is ideal for financial applications where privacy and security are essential, but collaboration between institutions is required.
Energy Web Chain: The Energy Web Chain is a consortium blockchain built specifically for the energy sector. It allows companies and organizations in the energy industry to work together to develop decentralized solutions for energy markets while ensuring efficient and secure operations.
Hybrid Blockchain
Hybrid blockchains combine elements of both public and private blockchains. Certain data and processes can be kept private in a hybrid blockchain, while others are made public. This allows organizations to enjoy the transparency and security provided by public blockchains while maintaining control and privacy over sensitive information.
Dragonchain: Dragonchain is a hybrid blockchain that allows businesses to maintain control over data while using the blockchain for decentralized applications. It enables organizations to control who can access their data while allowing them to interact with public blockchains like Ethereum or Bitcoin when needed.
XinFin (XDC Network): XinFin is a hybrid blockchain platform for international trade and finance. It offers the security and transparency of a public blockchain but allows enterprises to maintain control over sensitive data by keeping it private.

In Summary
Consider the use case and your organization’s unique requirements before deciding on a blockchain network. Although they may be slower and less private, public blockchains provide security and transparency. Although they forego some decentralization, private and consortium blockchains offer greater control, privacy, and efficiency. Types of Blockchain Networks For companies that need some control over the data they make public, hybrid blockchains provide the best of both worlds. Businesses and developers must grasp the various blockchain networks to use the technology as it evolves fully.
FAQs
1. What is the difference between a public and private blockchain?
A public blockchain allows anyone to participate in the network and access the data. It is fully decentralized and transparent. In contrast, a private blockchain is a permissioned network where only selected participants can join, offering more control and privacy.
2. Can businesses use public blockchains?
Yes, businesses can use public blockchains, but it may not be ideal for industries requiring privacy or control over data. Public blockchains are great for transparency but can be slow and inefficient for large-scale enterprise applications. In such cases, businesses often prefer private or consortium blockchains.
3. What are the advantages of using a consortium blockchain?
Consortium blockchains provide a middle ground between public and private blockchains. They offer more decentralization than private blockchains, as control is shared among multiple organizations but still provide privacy and efficiency. This makes them suitable for industries where collaboration between trusted entities is required.
4. Why is hybrid blockchain becoming popular?
Hybrid blockchains are gaining popularity because they offer the flexibility to maintain privacy over sensitive data while still interacting with public blockchains for transparency. This combination makes them suitable for industries like finance, healthcare, and supply chain management, where privacy and transparency are essential.
5. What industries benefit most from private blockchains?
Private blockchains are widely used in banking, healthcare, and supply chain management industries. These industries require secure, fast, and private transactions, where only approved participants can validate transactions and access sensitive data.
