Public blockchains are open to anyone, allowing them to join and participate in the network without permission.

Private blockchains are controlled by a single entity or organization, and only authorized participants can join and participate in the network.

Consortium blockchains are managed by a group of organizations or entities, and only authorized participants from these organizations can join and participate in the network.

Public blockchains are highly decentralized and secure due to their open and permissionless nature, making them resistant to censorship and manipulation.

Private blockchains are often used for enterprise applications and require permission to join, providing increased control and privacy for sensitive data.

Consortium blockchains combine features of both public and private blockchains, allowing authorized participants from multiple organizations to join and participate in the network.

Proof of Work is a consensus mechanism used in public blockchains to validate transactions by solving complex mathematical puzzles.

Proof of Stake is a consensus mechanism used in Proof of Stake blockchains to validate transactions based on the amount of cryptocurrency a participant holds.

Delegated Proof of Stake is a consensus mechanism used in Delegated Proof of Stake blockchains to validate transactions by elected delegates.
