I see some references to the hybrid blockchain. This can be a good advantage. There are some resources that claim that the hybrid blockchain is 51% less susceptible to hacker attacks. That is, transactions are more secure. Well, in addition, their cost is much lower.
I don't understand something in this concept. If in a private blockchain transactions are hidden, and in the public blockchain are open, will transactions be hidden in a hybrid blockchain? And who can check my transactions?
