To mine digital currencies like Bitcoin and Litecoin, cryptographically secure hash functions are used. What is the best advantage of using this phenomenon in this regard?
Hash functions detect error and have nothing to do with the digital currencies.
The decryption of hash function is easy so that the miner gets the reward.
Cryptographically secure hash functions are very hard to reverse and hence are suitable.
These currencies and the related network demand security that hash functions provide.
The correct answer is 'Cryptographically secure hash functions are very hard to reverse and hence are suitable'. Edit: I really don't like how this answer is worded, because hash functions are not just hard to reverse, you CAN'T reverse them. Poor word choice in my opinion.
