Proof Of Work : Explained |

Proof Of Work ExplainedIf you have been following the blockchain space you have probably heard of the term proof of work In this article I will try to explain the concept in a way that at the end of this article you can have a grasp of what POW really is both theoretically and in practical or technical aspect Understanding Hash FunctionsTo understand POW one has to learn about hash function you can skip this part if you already know about hash functions Simply put a hash function is a family of functions that take an input data this data can be a string of text an array of bytes etc and then the function returns a fixed length value can be bits bits bits etc Note that there are hundreds of hundred functions currently in use and the most widely used in the blockchain space is the SHAIn the example below we will use hash functions RIPEMD and SHA gt RIPEMD Of Eddy gt bbfedffccdeff RIPEMD gt SHA Of Eddy gt bfbefecbbadafcfeecace Since it s function we can even call it twice on the same value f f x gt SHA Of SHA Of Eddy Double hashing gt cafdfccdeeeffbeadfaceeabdbeeaeaOnline hash calculator How is POW computedThe first step of POW computation is concatenating or adding together different pieces of the block header data The result is a piece of data on which we can perform hash functions One important piece of the header data is called nonce which is a bits integerNOTE I won t be detailing on block header components in this piece the rabbit hole goes so deep that those can be an articles on their own Once we have the block header data the work can finally start The way it works is start by Double hashing the data with SHA hash function Extract a number from the bits output and Compare the result number against the target if it s bigger than the target the process is repeated again With the current network difficulty level this process can be done in extremely large number of sequences The current network hash rate is quintillions of hashes every second this led to development of ASIC miners which are hardware devices solely optimized for hash algorithm computation POW Steps In Pseudocode Concatenate header data HeaderData version prevBlockHash rootHash time targetNumber nonce We hash twice the header data DoubleHash SHA Of SHA Of HeaderData We convert the bits output to a large integer value ResultNumber Number from DoubleHash Compare the result number IF ResultNumber lt targetNumber We have found the right hash POW is completed Else We increment the nonce integer and go back again to Step Until we find a result number that is smaller than the target REFERENCES |
