Question   

What are the different types of blockchain?

Answer  

Public blockchain: These blockchains are completely open to following the idea of decentralization. They don’t have any restrictions, anyone having a computer and internet can participate in the network.

Private blockchain: These blockchains are not as decentralized as the public blockchain only selected nodes can participate in the process, making it more secure than the others.

Hybrid blockchain: It is the mixed content of the private and public blockchain, where some part is controlled by some organization and other makes are made visible as a public blockchain.

Consortium blockchain: It is a creative approach that solves the needs of the organization. This blockchain validates the transaction and also initiates or receives transactions.

Public permissioned blockchain: A public permissioned blockchain merges features of public and permissioned models, allowing public participation with entry permissions. It ensures transparent verification of information while maintaining privacy for specific users. Governed by a hybrid model, it employs decentralized consensus with additional oversight. Suited for use cases like supply chain management, trade finance, or identity verification, it balances public trust and regulatory control. Representing a compromise, public permissioned blockchains are still evolving, and choosing the right type depends on factors like security, privacy, scalability, and regulatory compliance.
