  1. Secure Hash Algorithm SHA - 256
  2. An incredibly big ammount of processing power + the astronomical number of possibilites makes it really hard to brute force the hashing algorithm.

  1. The hashing algorithm used in Bitcoin is SHA-256

  2. This hashing algorithm is really hard or almost impossible to brut-force due to the exponential nature of the encryption and computational power required to decrypt the permutations of the output which changes constantly making it near impossible to replicate the same output in a hash function. This makes it impractical to put the effort required to brute force which could literally take one their whole life to crack.

SHA-256.

Its nearly impossible with the length of the input data.

  1. What is the hashing algorithm called used in Bitcoin?
    SHA-256
  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    The mathematical difficulty of solving the algorithm continuously increases, and rewards are not based upon work done, but contain an element of chance.

  1. Bitcoin uses SHA-256 hashing algorithm.
  2. Hashing algorithm is almost impossible to brute-force because the only way to find out input data is to compare given hash with a hash from a presumable input data. Knowing that input data could be any digits, letters or even larger media files the possibility to guess right one tends to zero.

2 1. Why is this hashing algorithm really hard (almost impossible) to brute-force?
Due to the massive size of the possible outputs and the complication of the formula, the formula itself is nearly impossible to reverse engineer and this makes the only other option to guess the output, which would take forever to do, again due to the size.

  1. Secure Hash Algorithm 256

  2. Blender analogy: You can’t unblend the output (blended drink) to recreate the exact inputs (unblended ingredients) to brute-force the bitcoin algorithm.

  1. sha 256 because 256bit data transfer rate? idk.
  2. i guess the stuff is all mushed together. they said it was like a blender but i dont know what the fuck the ingredients are… are they the miner or the block what is a block how does a miner mine while solving a problem what is this shit come on fucking explain it i paid for you to teach me not some fucking web page not ran by you or anything just give me a video where i can actually learn a basic rundown of everything i need to know BEFORE i start the academy since i have to know some stuff before hand. which is not what you advertised.

Secure Hash Algorithm used in Bitcoin is named SHA-256

Why is this hashing algorithm really hard (almost impossible) to brute-force?
because any slight change in the input creates an output that has a completly different hash

  1. What is the hashing algorithm called used in Bitcoin?
    -SHA-256

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    -The combinations and amount of numbers would take too much computing power and time to solve

  1. SHA-256
  2. Because the amount of equations you’d need to solve to match the output of the hashing algorithm is so high, it would be unfeasible to undertake such a task.

    The possible combinations that can lead to a correct answer are so many that it is almost impossible to decipher with a bruce attack

SHA-256 is really hard to brute-force because it is puzzle friendly and it takes a lot of computational effort and resources.

it is called sha256
it is hard because of the structure of the algorithm sha 256…it would take a lot of timw to do it

  1. Its called SHA-256 (Secure Hash Algorithm)
  2. Because it is a random number between zero and a maximum 256 digit value, so it requires heavy computation power and programming to determine the right answer for the required target, it’s practically a lottery to determine it

  1. Secure hash algorithm SHA-256
  2. The amount of possibilities for the answer is too great to be just brute forced.

  1. Secure Hash Algorithm (SHA) SHA-256, invented by the National Security Agency (NSA) within the USA.

  2. Because it is extremely hard to find 2 inputs to produce the same output in a hash function and to reverse the function to get the input that gave the last output.

  1. it is called SHA 256
  2. because there are so many possibilities (2^256), so it is almost impossible to brute-force
