What is blockchain? Simple explanation with example

[elimana]

In simple words, blockchain is a kind of information recording and reporting system. Its difference from other systems is that the information stored on this type of system is shared among all members of a network. By using data encryption and distribution, the possibility of hacking, deleting and manipulating recorded information is almost eliminated.
