  1. Bitcoin uses SHA-256 algorithm for its hashing function.
  2. The probability of forcing it’s way by brute force is minimal due to large computation involved in the possible inputs to match the hash

1.) SHA-256
2.) The equations to solve get harder and harder, as more “brute-force” would come in. Even if there would be overwhelming force to do it, a few full nodes woul still keep a takeover of the network from happening, but that’s another topic.

  1. SHA-256 (Secure Hash Algorithm)

  2. Because of the one-way mechanism is guaranteed through intricate mathematical equations which do not allow the reversal of a new hash.

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

Secure Hash Algorithm, in short, named as SHA-256.

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

Because hashing algorithm using one-way mechanism, you could not alter it and even if there is a small / slightly different like comma or space inserted, the hash output will be totally different.

  1. Secure Hash Algorithm - SHA 256
  2. You will have to guess 2*256 possible optios which makes it impossible as of now.

1, Sha-256

2, Cause every guess is random, and no progress can be done. You can only keep on guessing. And the more people that guess the harder the answer becomes.

  1. SHA-256

  2. Because the calculation needed to get the previous data of the hash is almost impossible to get on a logical (or human) period of time.

1- The hashing algorithm of Bitcoin is called SHA-256, Secured Hash Algorithm.
2- Hash is a result of function of a hash algorithm. Hash algorithms are building blocks of Bitcoin blockchain terminals. Each algorithm function is different. Eeach algorithm produces unique hashes, one of 256 bit possibilities, the results are differentiating. So it is irreversible

    SHA 256 or Secure Hash Algorithm. Shout out to the NSA for doing good work.

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    The sheer amount of computational possibilities makes a brut force effort infeasible and not worth the effort.

  1. Secure Hashing Algorithm 256
  2. It generates a one way function, unique 256-bit length hash per input, which cannot be identified retracing the other direction, making the probability of guessing astronomically hard

  1. SHA-256 Algorithm

  2. With Bitcoin being available for so long, the difficulty of the algorithm became such a powerhouse that specific mining equipment must be used to mine efficiently. Along with each block being made will need more computational power to continue to break down SHA-256.

SHA 256 (Secure Hashing Algorithm)

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

Its almost impossible to brute force because of the 2^256 possibilities and only one match

Homework - Hashing

  1. What is the hashtag algorithm used in BTC

SHA-256

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

Basically SHA-256 hash has 2^256 random possibilities and it would require a lot of computational effort and resources to crack - the chances of someone randomly matching both the input with the output is unfathomable

cheers :beers:

  2. It’s difficult to brute force due to the program moving in a linear fashion and is very large in terms of probability.

  1. What is the hashing algorithm called used in Bitcoin? : Secure Hash Algorithm (SHA)

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force? : Bitcoin uses the SHA-256 Algorithm. The idea is to Hash a random string of data represented by the 256 bit code into a alpha numeric string of characters ranging from 0-256 bits. The more simple the output the more efficient the hash was computed. But what I think makes this really difficult is the fact that Bitcoin uses a series of concat functions to develop the output making it virtually impossible to determine the exact input to the hash function. This makes transactions on the Bitcoin BlockChain extremely secure.

The hashing algorithm used in Bitcoin is SHA-256.

This hashing algorithm is hard to brute-force because the algorithm can only be solved to find the ultimate hash output. They cannot be reversed.

  • SHA-256
  1. Why is this hashing algorithm really hard (almost impossible) to brute-force?
  • The work done involves increasingly difficult mathematical equations, hashes produced provides a random number between 0 and a max 256 digit value entailing a large number of possibilities, and with increased competition doing the work more computing power is required (making it almost impossible to use brute-force)
