  1. What is the hashing algorithm used in bitcoin.
    SHA-256

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force ?
    Because If your hash is below this target, you win. But oftentimes you will get a value above this target and the mining software will need to increment the nonce (block’s header). This involves changing the hash and trying again, over and over again.

Bitcoin Hash Algorithm called SHA256

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

Because they cannot be reversed to calculate the initial raw data.
If you change even a slightest comma or space the hash output will be completely different.
the network produces 1 block every 10 minutes and with every 2016 blocks, all Bitcoin clients compare their performance to the average time, which is two weeks. The difference in percentage, the target is modified accordingly, making the PoW equation more or less challenging.

  1. Secure Hash Algorithm – SHA-256
  2. Bitcoin hash uses 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.

  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 hash function is uni-directional and would therefore require too many 
          attempts to reconstruct its input.

  2. because it gets increasingly difficult after each block and requires an extreme amount of computational power just to have a chance of solving and earning. also it cannot be reversed or duplicated

  1. Bitcoins hashing algorithm is called SHA-256
  2. The computational power required to brute force bitcoins hashing algorithm is so vast due to the length of the number that it would be more feasible to use that computational power to mine bitcoins rather then try and brute force the algorithm.

Secure Hash Algorithm (SHA) named SHA-256

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

Every hash algorithm has distinct features and these algorithms can only be solved to find the ultimate hash output. The new hash algorithm cannot be reversed to calculate the initial raw data making it a one-way mechanism which is guaranteed through consensus and intricate math and as a result of the hash’s distinct features, it can never be used or treated as any form of digital fingerprint of the data which was originally processed.

    Sha 256 is the hashing algorithm used in Bitcoin.
  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    The total number of possibilities is so large that it is unlikely two people get the same result in their life time. This algorithm is almost impossible to brute force because it is very difficult to find 2 inputs to produce the same output in a hash function.

  • What is the hashing algorithm called used in Bitcoin?
    SHA-256 develop by NSA.
  • Why is this hashing algorithm really hard (almost impossible) to brute-force?
    Because of the level of complex math involved. Even minimal differences on the input result on completely different hash output.

  • The hash algorythm can only be used to solve the hash function output, and not the raw data.

2.Why is this hashing algorithm really hard (almost impossible) to brute-force?
SHA-256 cannot be reverse engineered for the intial source raw data, since the hash
function produces unique results, ultimate hash output and only works in a unilinear forward direction only
