Distinguishing Facts from Myths

facts of the myths revolving around blockchain technology.

to all, and every activity happening in the network is visible to all. This is wrong;
different security measures within the blocks and network, and even organizational-
level accessible settings, are there.
There are different types of blockchain implementations, such as public, where
