This mathematical problem is usually referred to as the hash puzzle. Solving the hash puzzle requires a large amount of computational power, so miners need to invest heavily in computing resources to gain a competitive advantage. In the PoW mechanism, miners compete to solve the hash puzzle and secure blocks, which are then added to the blockchain. The miner who successfully solves the puzzle is rewarded with newly  created cryptocurrencies and transaction fees.\n\nPlease note that the translation is approximate and may require further refinement."}]}],"pr":"1b4470c604003eacbdd9f45630787697b0ab7876d608b6792497f8dfd2ddb101"}
