How are Bitcoin hashes calculated?

The process of bitcoin mining uses a cryptographic hash algorithm called “Secure Hash Algorithm 256 (SHA-256).” It transforms any line of text or prose into a 256-bit (32-byte) hash value. In simple terms, it breaks apart words and sentences and turns them into fixed-length, indecipherable, alphanumeric strings.1 Şub 2022

“The Bitcoin network today has a hash rate of approximately 190 EH/s , so all the miners across the network are calculating the output of the SHA-256 cryptographic hash function approximately 190 quintillion times per second on average.”

On average, 144 blocks are mined daily and each contains 6.25 Bitcoins.

To attack Bitcoin you need at least 51% of all the hashrate in the world, now that the miners produce 100 quintillion hashes per second that’s becoming a very expensive and unlikely scenario. In short, the more hashing power used to mine Bitcoins, the harder it is for a single person to get 51% of it.

The Bitcoin hash rate is expressed as hashes per second (h/s) . Bitcoin’s network is large and powerful, and as a result, can calculate quintillions of hashes every second. For reference, a quintillion is a million million millions, or 1,000,000,000,000,000,000.

In cryptocurrency mining, a target hash is a numeric value that a hashed block header (which is used to identify individual blocks in a blockchain) must be less than or equal to in order for a new block to be awarded to a miner.

Each Bitcoin block takes 10 minutes to mine. This means that in theory, it will take just 10 minutes to mine 1 BTC (as part of the 6.25 BTC reward).
