Introduction
Are you curious about the four main types of blockchain? As one of the defining technologies behind modern digital transformations, blockchain is a secure, decentralized system that can help to ensure the trust and transparency of digital transactions. With so much talk around its potential applications, it’s important to understand the different types of blockchains and how they function.
The four main types of blockchain networks are centralized, decentralized, consortium, and hybrid blockchains. A centralized blockchain is one where all transactions occur within a single network managed by a central authority such as a financial institution or government organization. Decentralized blockchains are distributed across multiple nodes with no single authority managing them; these networks rely on consensus protocols for authentication and require members to agree on any changes or updates to be made.
Consortium blockchains involve a group of preselected entities that manage the network and jointly operate it; only authorized users can access this type of blockchain. Hybrid blockchains are systems that mix features from both centralized and decentralized networks; these are usually open networks with some level of control from an administrator or subset of users.
The security of each type of blockchain depends on its consensus protocol – the protocol used to verify transactions between participants in the network before they become permanent. Common protocols used in blockchains include proof of work (PoW), proof of stake (PoS), and delegated proof of stake (DPoS). In addition, smart contracts can be used to add an extra layer of security, verification, and transparency to transactions taking place on the network.

What Is Blockchain?
What is blockchain? Blockchain has become a buzzword in recent years, but many people don’t know exactly what blockchain is. Put simply, blockchain is a distributed, decentralized, cryptographically secured, peer-to-peer transaction ledger. Essentially, blockchain allows for the secure transfer of data and value between users without the need for a central authority or intermediary.
At its core, blockchain uses consensus mechanisms and immutable records to store data in a public or private fashion. This ensures that all transactions are validated and stored securely. Additionally, blockchain technology makes use of smart contracts which are self-executing digital contracts between parties that are enforced by computer code.
Now that we’ve discussed what blockchain is in general terms, let’s look closer at the four main types of blockchains: public, private permissioned, private permissionless, and consortium blockchains.
Public blockchains are open-source networks where anyone can join and access the network without permission from any external authority. Additionally, every record stored on these public ledgers is verifiable by all participants on the network such as Bitcoin and Ethereum.
Private permissioned blockchains are similar to public blockchains with the added restriction that only certain individuals or organizations can interact with them. These are typically used in corporate settings where only specific members can join the network such as Hyperledger Fabric or R3 Corda.
Private permissionless blockchains also have restricted access but don’t require authorization from an outside party to view records from within this type of system such as Monero or Zcash. This means that no one individual controls or governs these networks; rather they operate based on consensus mechanisms from all participants on the network.

Understanding the different types of blockchains is key to making an informed decision in realizing the full potential of blockchain technology. There are four main types of blockchains, Public Blockchains, Private Blockchains, Consortium Blockchains, and Hybrid Blockchains. Let us look at each of these four distinct types in more detail.
Public Blockchain: The most widely used type of blockchain today is the public blockchain. A public blockchain is a decentralized network that allows anyone to join and contribute to its consensus process. It is open source, meaning all parties involved can view its code and observe how it operates. Ethereum and Bitcoin are examples of popular public blockchains.
Private Blockchain: This type of blockchain is exactly what it sounds like – a private blockchain that allows only select members to participate in its consensus process or run a node on the network. This type of blockchain offers certain privacy features that make it ideal for certain organizations such as banks or government agencies who don’t want their data shared with other members of the public.
Consortium Blockchain: A consortium blockchain is managed by a group or consortium of organizations which grants permission to certain users to access the blockchain platform but still maintains some level of control over who can join and participate in the consensus process. This type of blockchain is useful for applications where multiple parties need to be involved for transparency reasons but don’t necessarily have trust between all participants.
Hybrid Blockchain: As its name implies, this type combines elements from both public and private blockchains, allowing users to choose which components they want on either side and which ones should stay exclusive for only one side’s use cases.

Benefits and Challenges of Different Types of Blockchains
There are four main types of blockchain technology: public, private, federated, and consortium. Each type has its own unique benefits and challenges that should be carefully considered when deciding which type of blockchain is right for a specific project.
Public blockchains are distributed ledgers that anyone can read, write to, and validate. They offer the highest level of decentralization and trust, but they also pose security risks due to their large user base. Private blockchains are more centralized versions of the public variety; they require the permission of the owner to view data or take part in any transactions. This ensures greater privacy and security but also restricts participation to invited parties only.
Federated blockchains provide increased security by linking multiple nodes across different organizations or entities rather than relying on a single node. Participants must all agree to verify every transaction before it is added to the blockchain and validated. This creates a trusted network with secure communications between participants but requires trust between them for it to work effectively.
Consortium blockchains employ a hybrid approach that allows for both public and private networks within an organization or community. This provides greater flexibility as different users can have access rights at different levels depending on their role within the organization or community. However, because transactions are not verified by all members in this setup, there is still some risk involved.
The benefits and challenges associated with each type of blockchain technology should be taken into account when deciding which type will best fit a specific business need.
Final Thoughts on The 4 Types Of Blockchain
When it comes to blockchain technology, there are four basic types that need to be understood. It’s important to have a good understanding of each in order to determine which type best meets your needs.
Public/permissionless blockchains are decentralized networks open to the public with no permissions needed. All data is stored on the blockchain, and all transactions take place on a trustless, immutable ledger. Consensus algorithms such as POW and POS are used to ensure trust and security among users.
Private / permissioned blockchains are private networks with access restricted by the blockchain administrators. These networks require permission from an administrator in order for new users to join, and also allow for different levels of access depending on user identity. Private blockchains also use consensus algorithms for trust and security but without the trustless environment of a public network.
Consortium blockchains are semiprivate networks that allow multiple organizations or groups to collaborate securely in a shared environment with predefined rights and restrictions set by the network’s creators or governing entities. These networks have higher privacy settings, as only specific members can access data within them.
Hybrid blockchains combine elements from both public and private blockchains into one distributed system in order to provide greater versatility, scalability, and flexibility than either type alone could offer. By having two separate ledgers (public & private), hybrid blockchains can maintain certain aspects of privacy as well as leverage the benefits of decentralization usually found in public chains.
