  1. What is the hashing algorithm called used in Bitcoin?

SHA-256

  1. Why is this hashing algorithm really hard (almost impossible) to brute-force?

A hash cannot be reversed to calculate the initial raw data.

  1. SHA-256 (Secure Hash Algorithm)

  2. Once the block has been mined it outputs a specific hash. If the key is modified and inputted back into the algorithm then the hash would be unverifiable.

  1. What is the hashing algorithm called used in Bitcoin?
    SHA-256. Secure Hash Algorithm which produces a hash of 256 bits
  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    Because the has function is not inversable. The slightest change in input parameters change the output completely

1.SHA-256
2. Because it would need to go through all computational possibilities 2^256 = 1.15x10^77

    1. SHA-256
  2. It is very hard to find 2 inputs that would give the same output hash function and it is impossible to find the input based on what the output is

  1. What is the hashing algorithm called used in Bitcoin?
    Secure Hash Algorithm named SHA-256.

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    The algorithm can only be solved to find the ultimate hash output, but cannot be reversed to calculate the initial raw data. Hence, this do not allow the reversal of a new hash.

  1. SHA-256 (secure hash algorithm)
  2. itā€™s so hard because there are so many potential inputs for the desired output.

  1. What is the hashing algorithm called used in Bitcoin?
    Sha 256 is the algorithm that is used on Bitcoin.

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    Sha generates a unique 256 bit signature for a text. Itā€™s hard to brute force as each input has a unique hash.

Note: I couldnā€™t access the article kept saying error. So had to look at Ivans answer.

1.). SHA-256

2.) Each hash algorithm has unique hash features and new hashes can not be reversed to calculate the initial raw data

  1. Secure Hash Algorithm (SHA)
  2. SHA-256 algorithms are hard to break because of the possiblities take long to break.

  1. hasing algorithm for bitcoin is called SHA-256
  2. Bitcoin has algorithms can only be solved to find the ultimate hash output, they can not be reversed to calculate the initial raw data. This one-way mechanism is guaranteed through intricate mathematical equations which do not allow the reversal of a new hash. Therefore, a Bitcoin hash is only solved in a linear, unidirectional manner .

I tried now and seems to be working. Maybe the website was down for a moment.

The algorithm used is called SHA 256, (Secured Hash Algorithm)

This algorithm takes a string of data of any length and transforms it to a 256 digit number. Mathematics make sure that this process is not reversible and it is almost impossible to brute-force reverse it

The hashing algorithm for bitcoin is called SHA-256

The hashing algorithm is irreversible, and the process has been in likened to putting a lot of different ingreedance into a food processer and then trying to decipher the contents from the pulp. Making the hashing algorithm all but impossible to brute-force.

  1. What is the hashing algorithm called used in Bitcoin?

A) SHA-256 made by the NSA (National Security Agency) by the US government

  1. Why is this hashing algorithm really hard (almost impossible) to brute-force?

A) Because it randomly generates hashes with 256 digits containing numbers and letters. It would mathematically take generations before you could find even one similar hash
