What is encryption? What is its role in Blockchain?

We know that the security of data is always matters. Encryption is a process of converting information or data into a code to prevent unauthorized access. It helps organizations to keep their data secure(i.e., prevent unauthorized access). In this technique, the data is encoded or changed into an unreadable format up to some extent before it is sent out of a network by the sender. The only receiver can understand how to decode the same.

In Blockchain technology, this approach is very useful because it makes the overall security and authenticity of blocks and help to keep them secure.
