The hashing algorithm for BTC is SHA -256. Itâs so hard to brute-force because each hash provides a random number between zero and a maximum 256 digit value and it the number of possibilities are too enormous. There is no way to obtain the original raw information from the final hash since the algorithm is linear and unidirectional.

- The hash algorithm is hard to brute-brute force because its theoretically impossible to reverse any output using a random input. Similar to to blending a smoothie. When you add your ingredients, theyâre easy to identify. Although, when you blend the ingredients together itâs impossible to recreate the ingredients.

Bitcoin hash algorithms can only be solved to find the ultimate hash output, they canât be reversed to calculate the initial raw data. This one-way mechanism is guaranteed through intricate mathematical equations which donât allow the reversal of a new hash. Therefore, a Bitcoin hash is only solved in a linear, unidirectional manner.

Hi, Thanks for the update re elliptic curve. I will adjust that thanks.
The second part I think we agree, I said like password brute-force attacks uses word combos. Not much use to brute-force a hash as no words or data is missing but the question mentioned it as a topic. Thanks for your input.
1. What is the hashing algorithm called used in Bitcoin?
1.A. SHA256 referring to the amount of bits (256) used in encryption.
2. Why is this hashing algorithm really hard (almost impossible) to brute-force?
2.A. The hashing algorithm is a linear, unidirectional coding using 256 bits of alpha numeric encryption. Due to lack of words and missing data, Brute-force would not work as it relies mostly on known words and names and would be almost impossible to decipher.

- It is a one way process - it is near impossible to reverse your way back to the input, and if you change something in the input then it will affect the output.

SHA-256 - Why is this hashing algorithm really hard (almost impossible) to brute-force?
Because a block is produced by hitting a random number between 0 and a 256 digit value or less than the number, that is randomly picked. - if your hashsâ output is higher than the blocks header, your computer/system has to try over and over again, until it hits the header or below. By now there is no computer that can work so fast, that it can hash the same blocks header 2 times.

- Secure Hash Algorithm or SHA-256
- Because the hashing algorithm is a deterministic or one-way function so it can not be reversed to calculate the initial raw data.

The hashing algorithm used in Bitcoin is Bitcoin hash algorithm
The hash target is a 256-bit alphanumeric code, which needs to be worked out in a linear, non-reversible format. The lower the targetâs value is, the harder it is to generate a new block.

Why is this hashing algorithm really hard (almost impossible) to brute-force?
For a few reasons (a) the function is unidirectional; the input set of data is impossible to figure out once the SHA-256 hash is developed. Once an output is determined, it cannot be reversed (b) an input of the same data will yield the same output. One minute change in the input will create a completely new hash. This eliminates the creation of a âdigital fingerprintâ © the process of mining involves a lot of competition- miners must reach a âtargetâ numeric chain, reach that target within a specific time-frame, and their software must adapt to increasingly difficult computation. On top of all this, mining rig hardware must be able to handle the amount of physical electricity that 247 work creates.

Why is this hashing algorithm really hard (almost impossible) to brute-force?:
- They are irreversible
- You canât get to the input data by reverse-engineering the output hash value
- A small change in the input will produce a vastly different hash value
- It is linear, they can not be reversed to calculate the initial raw data, any small change made to the group of input data, results in the hash of the new group being totally different.

- Why is this hashing algorithm really hard (almost impossible) to brute-force? It requires 2^256 +1 combinations before you will get the same hash output for 2 different inputs. This means that the chance for collisions and breaking the Hash function is very small
