Reading assignment: Hashing

#4619
  1. SHA- 256
  2. It is exceptionally hard to brute force the algorithm, for it is defined with structured but random variables that take meticulous effort to recreate. Like with the smoothie analogy, all the part of information are from legitimate sources of relevant code or information from the chain, but they are combined at random to make a function input, the hash “True” quality. This practically scrambles the necessary output formula to make the equation true.

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

  2. SHA-256 is almost impossible to brute-force due to the fact you can’t reverse engineer what the input was from knowing the output - you have to guess - the amount of guesses you would have to make to be correct with this particular hash algorithm is so large, you’re really just incentivised to do it the right way by setting up mining rigs with sufficient computing power to come out profitable by mining $BTC and helping secure the network

What is the hashing algorithm called used in Bitcoin?

  • SHA-256

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

  • The only way to re-calculate the data of a block is to put the same data through the hashing algorithm. With 2^256 variations of data blocks, it is almost impossible to recalculate the block data within 10 minutes (the time a new block has been created).

  • Sha 256 is the hashing algorithm used in Bitcoin.
  • 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.

    sha-256

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    Cracking sha-256 is very difficult with the current level of technology, and having said this, brute-forcing it is completely impractical.

  1. SHA-256 or Secure Hash Algorithm 256 is used in Bitcoin mining as well as for mining many Altcoins.
  2. Each successive algorithm is increasingly more difficult the the preceding making it harder and harder to brute-force as the blockchain continues to stack and become computationally larger and more complex… this coupled with the fact the algorithm cannot be reverse-engineered.

  1. SHA-256
  2. Because the raw data used for constructing a hash can not be traced back or reconstructed once the algorithm has been applied. The example that has been given, is that of a blended mixture, which consists of various ingredients and maintains it’s nutritious values, but it turned into something else, something unique, that can be recreated, if the exact same ingredients and method is used. The pulp itself though can never be reversed into its previous condition of whole ingredients.

SHA-256

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

In essence, using SHA-256 makes the blockchain virtually impossible to brute force because it would take too long to cycle through the possible input and output matches (or possibilities), making mutation unattainable.

Secure Hash Algorithm (SHA) named SHA-256.

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

Because you need an enormous amount of computer power to do it.

  1. SHA256

  2. Because it’s like a lottery and you need to try over and over again to get the
    target value.

It is an irreversible kind of function based on SHA-256 algorithm and brings a 256-bit alphanumeric code on it`s output.

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

Too many iterations required.

    The equations are too difficult to compute and would take too much time to brute force/would not be worth the hassle.

  • Too large of computation power is needed and also takes an extremely long time to get the result of the computation.

  1. SHA-256
  2. because no matter how big or small your input is, the output will always have a fixed 256-bits length. And when dealing with large amounts of data the chances of someone randomly matching both the input and output are astronomical with the possibility of it happening would take so long it doesn’t even matter.

  1. The hashing algorithm that is used to the bitcoin is called the Secure Hash Algorithm or SHA.
  2. The reason it is so hard to brute-force it is due to the complexity of the mathematics which would take more than one’s own life time to crack.

  2. SHA-256 - Secure Hash Algorithm
  3. Why is this hashing algorithm really hard (almost impossible) to brute-force?
  4. The algorithm is extremely hard to solve and once the Bitcoin algorithms are solved to find the ultimate hash output they cannot be revered to calculate the initial raw data.

  2. That’s because the process of solving the hash algortih need too much computational force that can leave you an entire life to solve it.
