The hashing algorithm used in Bitcoin is called SHA-256 (Secure Hash Algorithm 256)
-
It is almost impossible to brute force bitcoin hash algorithm because you can not guess or identify the raw data inputed to create the hash output by reversing the hash result. Even if you input the result, instead of giving back the raw data that created it, it will create another hash entirely.
Thereby, making it an unending vitious circle into a rabit hole of solving the raw data till enternity just like it is IMPOSSIBLE to get back raw fruits blended together to make a fruit juice.
If for example you are told to say exactly the size, shape of all the raw fruits blended, its impossible to say accurately, even though from the taste you may be able to say, the fruit juice contains mix of Mango, Lime, Pawpaw etc but you can get precise shapes and sizes of each fruits just by identifying there taste or colour blend in the fruit juice.

(SHA-256)
Why is this hashing algorithm really hard (almost impossible) to brute-force?
It can be compared as trying to win the lottery, too many active miners increases the difficult level of success. Varying the block’s header is a trial and error process and the chances of success are statistically very low and time consuming to match the hash in the blockchain.
Secure Hash Algorithm (SHA) named SHA-256, created by National Security Agency (NSA)
Their are to many possibilities and bitcoin hash can only be solved in a linear, unidirectional manner.

Why is this hashing algorithm really hard (almost impossible) to brute-force?
The hashing algorithm is almost impossible to brute force because the chances of success are statistically very low. With so many possibilities, mining requires high amounts of computational capacity, as well as dedicated hardware equipment. As there are so many miners in the network competing at the same time, the chances of brute-forcing the algorithm is very slim.
- SHA 256
-
- The possibilities are massive and the odds of brute-forcing are minuscule
1 - SHA-256
2 - the hash algorithm can only be use in one direction and have to be validated by the miners.
- Secure hash algorithm SHA-256
2.It is almost impossible to reverse the hash to find the original input and unlikely 2 cpus will get the same answer at the same time.

It is almost impossible to brute force because the it cannot be reversed to get the initial raw data. One character change on the input would change the output code completely.

Secure Hash Algorithm- 256 (SHA- 256)
-
from my understanding of the article, the system is designed to have a unidirectional and linear output. In theory it is possible to obtain the correct input but only at the cost of an enormous amounts of time and energy which is impractical, given the limited time required for the operation the odds are close to impossible.

Why is this hashing algorithm really hard (almost impossible) to brute-force?
It is almost impossible to to brute-force the hashing algorithm because the input/output possibilities are nearly endless that no human would have the time in their lifetime to figure out. Although, with quantum computing this is something that could be possible with endless computations running nonstop but does not seem to be anything to worry about in the near term.
- SHA256
- The amount of energy necessary to achieve an output combined with the number of possibilities creates a very difficult environment to solve a hash problem.
- SHA-256.
- The creation of a hash cannot be reversed and it’s not possible to check on the initial raw data when a hash is created to codify any new piece of information added to the blockchain. It requires a high computational capacity and hardware equipment to operate. Then, the algorithm creates a random hash that ranges between 0 and 256 that is usually above this target number, creating a new nonce to work with. As the number of miners has increased, it makes it difficult to solve the equation and to create a new block’s header / new BTC. That being said, the hashing algorithm is hard to brute-force because is linear and unidirectional, which is a way to keep high standards of security in the blockchain.

- Why is this hashing algorithm really hard (almost impossible) to brute-force?
Technically speaking, it is hard to brute-force the process of solving the hashing algorithm, which is carried out entirely at random. In order for any miner to solve (i.e brute-force) the algorithm, they would need to take a block’s hash, concatenate it with the nonce (i.e an arbitrary string of values), hash it again, and lastly compare the final result with the designated difficulty level. If the result finds itself below the difficulty level, then it is accepted and the new block is appended to the blockchain. If not, then everything needs to be hashed over again, where the process is repeated with a new nonce each time until the final output is less than the difficulty level.
Practically speaking, the algorithm is extremely hard (if not impossible) to brute-force/reverse-engineer because there is a specified hash rate for each block that needs to be mined in order to maintain a specific and predictable supply of Bitcoins. Miners have an incentive to mine more or less depending on how the difficulty level varies, which is itself determined by the number of miners actively participating to generate new blocks.
The algorithm utilizes components of math and game theory to achieve the desired result from participants.
Additionally, SHA-256 hashing algorithms are really hard to brute-force because no matter how big or small your input is, the output will always have a fixed 256-bits length, which results in 2^256 possible combinations (for binary bits of information made of 0s and 1s).
If alphanumeric sequences are allowed for, the total number of possible combinations then rises all the way up to 62^256 (10 digits from 0-9, in addition to 26 letters in the alphabet multiplied by 2 to account for both upper and lowercase letters, should case-sensitivity be a consideration).
