What are the types of blockchains?

There are three main types of blockchains: public, private, and consortium blockchains. Public blockchains, such as Bitcoin and Ethereum, are open to everyone and ensure maximum transparency. Private blockchains limit access, making them ideal for businesses where data confidentiality is important. Consortium blockchains are a network of several organizations that jointly manage processes, providing a balance between openness and security. Each type has its unique advantages depending on the needs of the users.
