What are the Types of Blockchains: Public, Private, and Consortium

Blockchain offers a safe and reliable method to authenticate digital transactions between numerous parties without the need for an independent authority or intermediary. Each block of this chain is protected by its specific cryptographic code, verifying all blocks that came before it. With blockchain, you can be sure your data will remain both secure and unchanging. Thanks to blockchain technology, confidential information is documented in a lasting manner – discouraging any form of manipulation or unauthorized changes. Bitcoin was the first use of this groundbreaking innovation; it has since been utilized by numerous industries for tasks such as supply chain management, healthcare records, and real estate transactions. Let’s see how does blockchain work?

Maintained by an expansive array of machines (nodes), the system validates and places these transactions in blocks which are then kept on its distributed ledger, free from interference or manipulation by any single entity or authority.

Transactions are authenticated and kept on a block through “mining”, which is the process of deciphering complex mathematical equations. Mining consumes vast amounts of computational energy and power, however, once added to the chain it cannot be modified without altering all future blocks; making data virtually impossible to tamper with or counterfeit.

Every block holds a distinct code termed a hash, which is generated through the data in that specific block, consisting of the preceding one’s hash. This forms an indestructible sequence of data by forming a “chain” between all blocks related to each other.

Blockchain utilizes consensus mechanisms to guarantee the safety and accuracy of its network. This process necessitates that most nodes confirm the status of the ledger, making data manipulation difficult as any attempts are quickly identified and rebuffed by other parts of the network.

What are the Different Types of Blockchains?

Wondering, how many types of blockchains are there? Read on to learn more.

Public Blockchain

What is a public blockchain? An open-source network provides a decentralized platform for anyone to join and take part in it. No single entity rules this type of system, but instead, it is sustained by an enormous number of nodes contributing towards checking and storing transactions on the chain. As a result, such networks are more reliable than those controlled by any one group or individual as there isn’t just one point of failure.

All data on public networks are completely transparent, giving anyone access to view the ledger as well as validate any trades. To protect user privacy while maintaining safety, public networks utilize cryptography algorithms so that users can process their deals without having to reveal who they really are.

Bitcoin, one of the most renowned public networks to date, was born in 2009. This peer-to-peer digital currency utilizes a ledger system that is accessible to anyone who wishes to view it; other examples are Ethereum, Litecoin, and Ripple all of which employ this same technology.

Public networks are appreciated for their openness, clarity, and availability. These features grant everyone the possibility to join in on the network which makes them ideal for apps that call for a higher degree of decentralization such as banking services, supply chain management, or government records.

Private Blockchain

Private networks differ from public ones in that access to the blockchain is restricted, and only users who get permission can join. This allows for a more controlled environment, making private networks centralized rather than decentralized like their public counterparts. By permitting select entities to join, these networks become tailored towards achieving a shared goal set by its governing body or individual entity. Advantages:

  • Private networks grant users greater levels of privacy and security, as well as faster processing times. This is because the nodes that participate in a private blockchain are already known and trusted by one another; they collaborate to authenticate and document data quickly and securely.
  • Businesses and companies use private networks to streamline their processes, optimize performance, and produce closed ecosystems. Here are just three examples: Corda and Quorum. Through these networks, users can securely interact with each other in a secure setting that is specifically designed for them.
  • Private blockchains offer the advantage of being tailored to the individual needs of users, such as reduced fees, quicker processing times, and enhanced security and privacy. Despite this benefit, these networks lack transparency in comparison to public ones due to their exclusive nature.

Consortium Blockchain

A consortium blockchain is a remarkable, revolutionary type of network. This unique amalgamation between public and private blockchains enables both decentralization and restricted access. Essentially, it is run by an alliance of organizations or entities that work in unison to keep the network stable.

Different from public networks, consortiums are formed by known and trusted participants who collaborate on the validation of transactions. Unlike private blockchains, however, a single entity does not manage the network rather it is more decentralized in its operation. Moreover, access to this network is limited as users must get permission beforehand to join.

Consortium blockchains offer organizations the perfect platform to collaborate on joint projects while maintaining complete confidentiality. For instance, banks can use a consortium network for secure information sharing between them that adheres to transparency standards and preserves the ultimate discretion of the chain’s administration.

Consortium blockchains offer the best of both worlds – a high degree of privacy and control while facilitating transparency and accountability. Additionally, they can process transactions much faster than public blockchains due to having fewer nodes on their networks. 

The Bottom Line

In this article, we discussed different types of blockchain. To conclude, blockchain technology has advanced impressively since its inception in 2009. Different types of blockchains have been designed to suit the varying demands of various industries and applications; public blockchains, private blockchains, and consortiums all possess their own particular features that make them fit specific requirements.

Without a doubt, blockchain technology is revolutionizing the way we share and transfer data. In addition to its already diverse use cases and applications, there’s no limit as to what this cutting-edge technology can do in the near future. This bold innovation will continue to shape our lives for years to come.
