The major difference between the public and private blockchain is the consensus mechanism. In public blockchain, you do not trust any of the other members, so the amount of computation overhead that is involved in verifying or validating every transaction is quite high and time consuming. Whereas in a private blockchain there’s usually a greater amount of permission-based trust involved, so you can use simpler and faster consensus algorithms.
