In the first place, SHA-256 is a hash function that outputs a fixed length value (hash value) from the original text of any length (in this case, the estimated value of the password entered by the ...

As the price climbs, so does the Bitcoin network's hash rate -- or the computing power being used to verify transactions and mine new Bitcoin. But what exactly is hashrate, and does it matter?

The hash function is a mathematical algorithm that takes digital data as an input and spits it back out as an encrypted string of letters and numbers.

Hash attack economics Starting with the basics, Bitcoin is encrypted by transactions using what's called a Secure Hashing Algorithm 256 (shortened to SHA-256). It is a one-way function, meaning ...
