A. AES 256
B. SHA-256
C. BITCOIN-160
D. BLAKE2


Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is B. SHA-256.

  • SHA-256 is the most popular hash function used in cryptocurrencies.
  • BLAKE2 is a hash function but not commonly used in cryptocurrencies.
