The goal of a miner is to take the current block’s header, add a random number to it called the nonce, and calculate its hash. This numeric value of the hash must be smaller than the target value. That’s all there is to it. But it’s much easier said than done.

WebMar 25, 2024 · The SHA-256 hashing algorithm is now one of the most extensively used hashing algorithms since it has yet to be cracked and the hashes are generated rapidly when compared to other safe hashes such as the SHA-512. WebSHA stands for secure hashing algorithm. SHA is a modified version of MD5 and used for hashing data and certificates. A hashing algorithm shortens the input data into a smaller form that cannot be understood by using bitwise operations, modular additions, and compression functions.
