What is the main difference between public and private blockchains?
The most important difference is the role of the user on the network and how the identity is managed. In a private blockchain, the creator of the network knows from the beginning who the participants are. On a public network, you can’t build a permission-based solution and the users have all guarantees of anonymity.
