Blockchain technology has revolutionized how we think about data, transactions, and security in the digital age. It emerged as the backbone of cryptocurrencies, primarily Bitcoin, but has since expanded its horizons to various industries. One of the remarkable aspects of Blockchain is its adaptability, which has led to the development of different types of Blockchain, each tailored to specific needs and use cases.
In this comprehensive guide, we will delve into the Blockchain world, exploring its various types, how they work, their advantages, disadvantages, and real-world use cases.
Why Do We Need Different Types of Blockchain?
Blockchain technology started as a single concept. However as it gained traction and found applications in various domains, it became apparent that more than one-size-fits-all solutions were needed.
The need for different types of Blockchain technology arose from the recognition that other industries and use cases require varying levels of decentralization, privacy, and scalability.
Here are some reasons why different types of Blockchains are essential:
Diverse Use Cases: Different industries, such as finance, healthcare, supply chain, and government, have unique requirements. Some need public transparency and immutability, while others prioritize privacy and control. Customized Blockchains cater to these specific needs.
Scalability: As Blockchain adoption grew, it became clear that public Blockchain like Bitcoin and Ethereum faced scalability challenges. Customized Blockchains have emerged to address these issues and offer faster transaction processing.
Privacy: While public Blockchains are transparent by design, specific applications, like healthcare or voting systems, demand privacy. Private and permissioned Blockchains provide the necessary confidentiality.
Regulatory Compliance: Various industries are subject to stringent regulatory requirements. Permissioned Blockchains can be designed to meet these standards, facilitating adoption.
Now, let's explore 4 types of Blockchain networks and their characteristics.
How Different Types of Blockchain Work
What is Public Blockchain?
A Public Blockchain is open to anyone and is maintained by a decentralized network of nodes (computers) worldwide. They use consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) to validate transactions and add them to the Blockchain. Bitcoin and Ethereum are prime public Blockchain examples.
Advantages of Public Blockchain:
- High transparency and security due to decentralization.
- Resistance to censorship and control.
- Anyone can participate and verify transactions.
Public Blockchain Disadvantages:
- Scalability issues lead to slow transactions and high fees.
- Lack of privacy as all transactions are visible.
- Energy-intensive PoW consensus can be environmentally unsustainable.
Public Blockchain Use Cases:
- Cryptocurrencies like Bitcoin.
- Decentralized applications (DApps) on Ethereum.
- Crowdfunding through Initial Coin Offerings (ICOs).
What is Private Blockchain?
Private Blockchains are restricted to a specific group of participants who have been granted access. Organizations or consortia often use them to streamline operations and enhance security. In a private key Blockchain, the participants can be predetermined and trusted entities, such as banks, businesses, or government agencies.
Private Blockchain Advantages:
- Greater control and permission management.
- Enhanced privacy as only authorized parties can access the network.
- Higher transaction throughput and faster confirmation times.
Private Blockchain Disadvantages:
- Limited decentralization, potentially leading to single points of failure.
- Reduced transparency compared to public Blockchains.
- Limited use cases due to closed networks.
Private Blockchain Use Cases:
- Supply chain management for tracking goods.
- Interbank transactions for financial institutions is one of the fine private Blockchain examples.
- Internal record-keeping and auditing within organizations.
What is Permissioned Blockchain?
Permissioned Blockchains strike a balance between public and private Blockchains. They are accessible only to approved participants, but a decentralized set of nodes maintains the network. This approach carries some decentralization while ensuring that network access is controlled.
Permissioned Blockchain Advantages:
- Improved scalability and performance compared to public Blockchains.
- Enhanced privacy compared to public Blockchains.
- Compliance with regulatory requirements.
Permissioned Blockchain Disadvantages:
- It is more decentralized and censorship-resistant than public Blockchains.
- It still needs to be improved in terms of transparency compared to public Blockchains.
- Requires trust in the network operator to some extent.
Permissioned Blockchain Use Cases:
- Cross-border payments between financial institutions.
- Supply chain visibility with selected partners.
- Identity verification in government services.
What is Consortium Blockchain?
Consortium Blockchains are a variation of permissioned Blockchains where a group of organizations or entities jointly operate the network. These organizations work together so that all types of transactions can be stored in Blockchain; no single entity has complete control.
Advantages of Consortium Blockchain:
- Shared governance among consortium members.
- Enhanced trust among participants.
- Scalable and efficient for specific industries.
Disadvantages of consortium Blockchain:
- Limited decentralization compared to public Blockchains.
- Consortium members must trust each other.
- It may not be suitable for entirely open applications.
Consortium Blockchain Use Cases:
- Trade finance among multiple banks.
- Collaborative research in the pharmaceutical industry.
- Supply chain tracking involving multiple stakeholders is one of consortium Blockchain examples.
Conclusion
Blockchain technology has evolved significantly since its inception, leading to the development of various types of Blockchains to cater to diverse needs across industries. The choice of Blockchain type depends on factors like decentralization, privacy, scalability, and regulatory compliance.
As Blockchain technology matures, we can expect further innovations and hybrid solutions that combine the best features of different Blockchain types to address complex challenges and unlock new possibilities across various sectors. The future of Blockchain holds exciting potential, and its impact on industries and society is bound to expand as these technologies evolve.
Whether it's a public Blockchain enabling open financial systems, a private Blockchain enhancing supply chain transparency, or a consortium Blockchain fostering collaboration among industry players, the Blockchain ecosystem continues to evolve, providing solutions that have the potential to reshape the way we interact, transact, and trust in the digital age.

FAQS
You can verify transactions in public Blockchains through mining where people volunteer to solve cryptographic puzzles in return for incentives, usually in the form of cryptocurrency. This verification method, known as 'proof of work,' is designed to prevent cyber attacks from any single entity or group.
Smart contracts are a great replacement for elementary legal agreements. They excel in automating simple and binary tasks. However, they still need more flexibility and recognition for complex contracts. The choice depends on the context, with legal expertise often required.
Permissioned Blockchains are generally considered more secure as compared to public Blockchains like Bitcoin. Their access control layer makes them a preferred choice for defined roles, verified identities, and secure network access.
Blockchain technology permits decentralization only where and when required, whereas public and private Blockchains deal with it in their own ways. If you use a hybrid Blockchain, you can keep the information confidential from general users while still making it verifiable.
The primary difference between public and private Blockchains is their accessibility. Public Blockchains are open to everyone, while private Blockchains are limited to a specific group. Also, private Blockchain platforms are more centralized because a single authority controls the network.
