Comparison Between Private Public Hybrid and Federated Blockchains: Full Guide
Blockchain technology has transformed the management and recording of data, providing decentralized solutions across various industries. While there are different types of blockchains, each serves distinct purposes and functionalities. This guide will explore the differences between public, private, hybrid, and federated blockchains, helping you determine which type best suits your requirements.
1- What is a Blockchain?
A blockchain is a digital ledger that securely records transactions and data in a transparent and decentralized manner. Originating in the 1980s, it gained widespread attention with the launch of Bitcoin by the pseudonymous creator, Satoshi Nakamoto . The technology enhances traditional ledger systems, allowing for secure and efficient data handling without intermediaries.
2- Types of Blockchains
There are 4 main types of blockchains, and they can be categorized based on their accessibility, control, and functionalities:
- Public
- Private
- Hybrid
- Federated
3- Key Features, Advantages, and Challenges by Blockchain Type
- Public Blockchains:
Public blockchains are open-source, decentralized ledgers where anyone can participate in transactions. They offer transparency and security through decentralized nodes and are often used for cryptocurrencies like Bitcoin and Ethereum.- Key Features: Decentralized nodes, open-source code, immutable transactions.
- Advantages: Global accessibility, resistance to censorship, data integrity.
- Challenges: Scalability issues, high energy consumption, and complexity for non-technical users.
- Example of Token Used:
Bitcoin (BTC): The first and most well-known cryptocurrency, operating on a fully decentralized public blockchain.
- Private Blockchains:
Private blockchains are controlled by a single entity, allowing for restricted access and faster transaction speeds. They are beneficial for internal management within organizations.- Key Features: Restricted access, better scalability, and faster transactions.
- Advantages: Efficiency for internal management, customization for specific industries, lower energy consumption.
- Challenges: Centralization risks, regulatory uncertainty, interoperability issues.
- Example of Token Used:
Chainlink (LINK): Often used in private blockchain solutions, Chainlink provides decentralized oracles to smart contracts across various blockchains.
- Hybrid Blockchains:
Hybrid blockchains blend features of both public and private blockchains, enabling selective access to data. This flexibility allows organizations to maintain confidentiality for certain data while benefiting from the transparency of public blockchains.- Key Features: Controlled access, a mix of decentralization and centralization, flexibility for various use cases.
- Advantages: Enhanced privacy with public verification, scalable due to fewer public nodes.
- Challenges: Complex management of balancing public and private aspects, less transparency than fully public blockchains.
- Example of Token Used:
VeChain (VET): A hybrid blockchain that allows businesses to use private chains for sensitive data while benefiting from public blockchain features for transparency.
- Federated Blockchains:
Also known as consortium blockchains, federated blockchains share control among a group of organizations instead of a single entity. Only selected participants can validate transactions, enhancing efficiency and security.- Key Features: Permissioned network, collaborative control among multiple entities.
- Advantages: Greater scalability, increased privacy, and control over access.
- Challenges: Centralization risks, and trust issues among participants.
- Example of Token Used:
Ripple (XRP): Ripple uses a federated consensus algorithm and is often utilized by financial institutions for cross-border payments, serving as a bridge currency.

Each blockchain type— public, private , hybrid, and federated —has its unique strengths and weaknesses. Public blockchains excel in decentralization and transparency, while private blockchains offer control and customization. Hybrid blockchains balance privacy and transparency, and federated blockchains provide collaborative control. Your choice among them will depend on your specific needs, whether you require global accessibility or secure internal management.
