Blockchain 100 Q 59th: What is a hashing algorithm?

The hashing algorithm is a cryptographic algorithm that can only be encrypted and cannot be decrypted, which converts any length of information into a fixed-length string.

There are two characteristics of this string:

1. Even if the input value changes only a little, the output hash value will also be poor.

2. Only the exact same input value can get exactly the same output value.

3. There is no regularity between the input value and the output value, so the input value cannot be calculated from the output value. To find the specified output value, only the enumeration method is used: Changing the input value continuously, looking for the output value that satisfies the condition.

The hashing algorithm guarantees that the Bitcoin mining cannot be reversed to deduce the result. So, the miners continue to operate, essentially in the brute force to crack the correct input value, who first find who will be able to obtain a bitcoin reward.
