usa wholesale jewelry suppliers What is the hash algorithm? How to ensure the fairness of mining?
hash algorithm is a cryptographic algorithm that can only be encrypted and cannot decrypt. The information of any length can be converted into a fixed length string.
This string has two features:
1. Even if the input value is only changed, the output hash value will be different.
2, only the same input value can get the exactly the same output value.
3, there is no regular input value and output value, so the input value cannot be calculated by the output value. If you want to find the specified output value, you can only adopt an enumeration method: constantly replace the input value to find the output value that meets the conditions.
Have algorithm guarantees that Bitcoin mining cannot derive the results in reverse. Therefore, the continuous operation of the miners is essentially the correct input value of violent cracking. Whoever finds first can get Bitcoin rewards.
wholesale jewelry in bulk from china The hash algorithm adopted by Bitcoin needs a lot of hash functions in the Bitcoin system. The Bitcoin system is stipulated in this way: Every ten minutes, everyone needs to calculate the hash function, and the calculated value must meet my regulations. Whoever calculates fast, who will get Bitcoin as a reward.
