- SHA(Secure Hash Algorithm) -256
- As brute-force works by calculating every possible combination that could make up a password, the hashing algorithm SHA-256 can only be solved to find the ultimate hash output, they can not be reversed to calculate the initial raw data. Therefore it is next to impossible to brute-force in order to figure out the input.

Why is this hashing algorithm really hard (almost impossible) to brute-force?
It would take an extremely long time to break the hashing algorithm in that there are way too many possibilities. It is just not feasible.

Essentially mining is ābrute forceā, in that the miners attempt all possible combinations to achieve the hash. If everyone involved in mining is using the same technique to earn the Bitcoin, thereās no shortcut to success that would represent what ābrute forceā is in something like a password-enabled login.
Given the target drops over time, the success of the mining diminishes over time as well.

due to disting features including that each one produces unique hash that cannot be reversed to calculate the initial raw data ( universe would to colapse before this could be solved due to mathematical dificulty) - one way mechanism guaranteed through intricate mathematical equations that are solved in linear undirectional manner

2, because hashing algorithm almost impossible to be reversed from the output, after a hash has been added to the block chain any change made to the data involved would leave a mark for participants of the network to be seen.

Why is this hashing algorithm really hard (almost impossible) to brute-force? Because the result is so complex it is nearly impossible to duplicate. Attempting to do so would be a waste of resources and require too much effort. The juice is not worth the squeeze.

The algorithm is almost impossible to brute force because it is almost impossible to find the input based on the output. The example that was used in the article was, if you put fruit in a blender and blended it up, although all the fruit is still in the blender it would be impossible to put it back in its original form. You are not able to find the input from the output.

It is impossible to brute force because the sheer number of possible outcomes mean the reward would almost certainly be outweighed by the effort required to brute force it.

This hashing algorithm is nearly impossible to brute force because it works in a unilinear direction. Hashes can only be solved to find the hash output and cannot be reverse engineered to calculate the original raw data.

What is the hashing algorithm called used in Bitcoin? The most popular cryptocurrency in the world uses a Secure Hash Algorithm (SHA) named SHA-256. Contrary to what some might think, this algorithm was not invented by the creator of Bitcoin, Satoshi Nakamoto, but by the National Security Agency (NSA) within the USA.

Mining is considered a lottery because rewards are not based on work done. Each hash provides a random number between zero and a maximum 256 digit value. If your hash is below this target, you win the lottery. But often you will get a value above this target and the mining software will need to increment the nonce (blockās header). This involves changing the hash and trying again, over and over again. Varying the blockās header is a trial and error process and 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.

A brute-force attack cost is proportional to the number of solutions. With Bitcoin, blocks are created every 10 minutes and the hash for the current block uses the output from the previous block. This makes nearly impossible to brute-force attack bitcoin.
