Reading assignment: Hashing

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

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
    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, for that is almost impossible to brute-force.

  1. its called SHA-256
  2. because it cannot be reversed engineered ( once mixed you cannot take back what was done like blending food you know what you had but you cant put it back the way it was let alone sperating the ingredients)

What is the hashing algorithm called used in Bitcoin?
Hash Algorithm (SHA) named SHA-256.
Why is this hashing algorithm really hard (almost impossible) to brute-force?
Every such algorithm has distinct features, including the important feature that each one produces unique hashes. Furthermore, these Bitcoin has algorithms can only be solved to find the ultimate hash output, they can not be reversed to calculate the initial raw data.

Answer the questions below.

  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 only way to solve a hash algorithm requires trial and error. As higher the hash, more dedicated software and hardware is needed since there are trillions of computations until by luck one hash is resolved.

  2. There is constant bit modification of the target, so finding a hash algorithm would be hard, as it is always changing.

  1. It is called Secure Hash Algrithm short SHA in 256 bit.

  2. Every hash is an unique output and can’t be changed back to the original input, it is a one way translation. The hash will be the same, if the input is the same, but if there is a slight diffrent, the output gets fundamental diffrent.

1.) Bitcoin uses the SHA-256, which stands for Secure Hashing Algorithm (256-bit).

2.) With a 256-bit hash size, the number of possibilities is incredibly high (making it very difficult to find a hash that produces a number less than the block’s header target). In addition, an SHA-256 hash cannot be reversed to extract the original input data. These two features combined make the blockchain very secure.

  1. Bitcoin’s hashing algorithm is called “SHA-256.”

  2. There are many factors that support the safety and security of Bitcoin’s hashing algorithm making it nearly impossible to brute force. Perhaps the main feature is that the algorithm has distinct features and produces unique hashes that cannot be reversed, (linear and unidirectional) making it impossible to find the original data processes. The data varies in size and forms that translate in to alpha numeric sizes depending on the hash function. 256 bit is large.The growth rate and hash rate also gives Bitcoin safety and security. Having many miners located apart throughout the world with no individual entity owning larger shares also gives Bitcoin security. Any discrepancies, questions require open, lengthy and vigorous discussion and agreement.

  2. Theoretically is possible to brute force it. Make a computer to try endless combination of hash numbers , but it would take life times, the number of combinations is a number of 2^256 just a few more zeroes and is going to have the same length as the total number of atoms in the universe.
    Is a waste of time and resources. Nobody have tried that yet.

  2. It is a linear algorithm, with impossibilities of reverse engineering. Therefore it cannot be replicated, only moving forward solving for the next hash. There is no equation to readily identify and therefore obtain the hash. It is unique and subject to each marker within its initial code.
