In today’s digital age, the term “blockchain” is buzzing everywhere. From finance to healthcare, supply chain to voting systems, blockchain technology is revolutionizing numerous industries. But did you know that blockchain isn’t a one-size-fits-all concept? Just like there are different types of cuisines or music genres, blockchain comes in various forms, each with its own unique characteristics and functionalities. Let’s embark on a journey to unravel the intriguing world of blockchain and discover its diverse types.

Public Blockchain

Imagine a bustling city square where anyone can come and participate without any restrictions. That’s precisely what a public blockchain offers. It’s an open network where anyone can join, read, write, and participate in the consensus process. Bitcoin and Ethereum are prime examples of public blockchains, fostering decentralization and transparency on a global scale.

Private Blockchain

Now, shift your focus to an exclusive club with restricted access. That’s the essence of a private blockchain. Unlike its public counterpart, a private blockchain is permissioned, meaning only authorized users can participate in the network. Enterprises often utilize private blockchains to maintain privacy, control, and efficiency within their ecosystem.

Consortium Blockchain

Picture a group project where multiple parties collaborate for a common goal. That’s the essence of a consortium blockchain. In this type, a predefined group of organizations jointly operate and validate transactions. Consortium blockchains strike a balance between the openness of public blockchains and the control of private ones, making them suitable for industries like banking, where multiple entities need to collaborate while maintaining certain levels of control.

Hybrid Blockchain

Now, let’s blend the best of both worlds. That’s precisely what a hybrid blockchain does. It combines elements of both public and private blockchains to cater to diverse business needs. In a hybrid blockchain, certain data or transactions are kept private, while others are accessible to the public. This type offers flexibility and scalability, making it suitable for various use cases, including supply chain management and healthcare.

Permissioned Blockchain

Imagine a VIP section in a concert venue where only invited guests can enter. That’s the concept behind a permissioned blockchain. In this type, access is restricted to a select group of participants chosen by the network owner. Permissioned blockchains prioritize security and control, making them ideal for applications requiring strict regulatory compliance, such as identity management and voting systems.


Now, imagine a parallel universe running alongside the main blockchain. That’s the essence of a sidechain. Sidechains are auxiliary blockchains that operate alongside the primary blockchain, allowing for specific tasks or functionalities without congesting the main network. They enhance scalability and interoperability, enabling developers to experiment with new features or conduct transactions more efficiently.


blockchain technology is far from monolithic; it’s a dynamic ecosystem comprising various types tailored to specific use cases and preferences. Whether you’re a tech enthusiast, a business owner, or simply curious about emerging technologies, understanding the different types of blockchain is crucial in navigating the ever-evolving landscape of decentralized innovation. So, dive deeper, explore further, and embrace the limitless possibilities of blockchain technology!
