Hash identifying each block in the blockchain is generated using which of the following cryptographic algorithm?

A)  SHA64
B)  SHA128
C)  SHA256
D)  None of the Above

Correct Answer :   SHA256


Explanation : SHA 256 is a member of the SHA 2 algorithm family, with SHA standing for Secure Hash Algorithm. It was a joint effort between the National Security Agency and the National Institute of Standards and Technology to introduce a successor to the SHA 1 family, which was slowly losing power against brute force attacks. It was published in 2001.
