What is the hashing algorithm called used in Bitcoin?
Bitcoin uses the SHA-256 hashing algorithm.
Why is this hashing algorithm really hard (almost impossible) to brute-force?
A hashing algorithm is a complex series of mathematical computations applied on the provided data producing a 256 bit buffer sequence (in this case). The 256 bit (32 byte buffer) sequence is usually represented in hex. My view on this is as follows:
Since hashing functions are one-way, one cannot know if they have got the right result when trying to brute force through the different potential combinations of a 32 byte buffer. To know the hash, one really needs to pass the original buffer through the hashing algorithm making a brute force attack impractical. Furthermore, this is a one way cryptographic function which only goes from source to hash and never vice versa.
- the hashing algorithm used in bitcoin is SHA-256.
2.the hashing algorithm is almost impossible to crack because its not possible for two inputs to get the same output as the range of the hashing is SHA-256.(1-256)

Secure Hash Algorithm (SHA) named SHA-256
- Why is this hashing algorithm really hard (almost impossible) to brute-force?
As brute forcing works like going trough each possible input string and trying it, and each hash provides a random number between 0 and 256 digit value it would take an enormous amount of time to find the correct value via brute force.
- its called SHA256 ALGORITHM
- because its only an one way equation
1 - SHA256
2 - Oneway and fixed length output of hash functions
- sha 256
- once the sha 256 hash is created through complex mathematical equation, it can’t be reverse to recover the original raw data, thus output = input (not possible).
- A universal translator for data
- A hash cannot be reversed to get the original data
- SHA 256
- Bitcoin hash is only solved in a linear, unidirectional manner.
A simple analogy to understand a hash is to imagine a food blender with a mixture of ingredients. At first, the ingredients are distinct and easily identifiable, but once the blender is on they lose their characteristics and become a blended mixture. Whilst their characteristics (nutrients) are still present in the mixture, it is impossible for anyone to reconstruct the individual ingredients from this pulp.

Secure Hash Algorithm- 256 (SHA-256) - Why is this hashing algorithm really hard (almost impossible) to brute-force?
Bitcoin miners work to solve difficult mathematical equations, adding new blocks to the blockchain using the Secure Hash Algorithm (SHA-256).
Its called SHA 256
It’s almost impossible to solve because it’s really long which makes the unique 256-bit signature really hard to crack. Definitely not worth the resources to do so.
The hash rate used by bitcoin is called SHA-256.
Every input into the hash function produces a unique 256 bit hash, The enormous number of combinations required to brute force make it virtually impossible to achieve.
1)SHA-256
2) almost impossible to find inputs- blender analogy, after food is blended it is impossible to reconstruct the food to its original form but all nutrients and amounts are the same of each individual ingredient

SHA-256 (Secure Hashing Algorithm 256-bit) -
Why is this hashing algorithm really hard (almost impossible) to brute-force?
You are essentially trying figure out the input, from an output that is an alphanumerical value of 256 characters. So the chances of doing so are extremely hard.
1. What is the hashing algorithm called used in Bitcoin?
Bitcoin use a Secure Hash Algorithm (SHA) named SHA-256.
2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
Well, I have to say it is hard to bruteforce because hash value came from one way generated and must not be able to revert back to the original string but it not really impossible to bruteforce.It just hard to bruteforce because it need random salt mix with the important string that you want to hidden.
- SHA - 256 algorithm
- Brute-force algorithm by the endless possibilities and time required to complete computations makes it infeasible to find it.
- Sha 256
- The odds of arriving at the necessary character combination by trial and error with current computational power are nearly impossible within a useful timeframe.

Secure Hash Algorithm (SHA)-256.

Food and a blender. Good luck.
SHA256
It is hard (impossible for a lifetime) to reverse the output back to input
Sha256 is hashing algorithm
The total number of possibilities is too large
- sha-256
- because it is impossible to cheat, the system will recognize any wrong input or output
