How does proof of work, um,work? This essentially requires miners (computers that run the network and 'mine' new bitcoin) to solve computational puzzles, each with a different solution. …bitcoin miners deploy huge amount of resources in the form of mining hardware (capital investment) and electricity (operational however, before the bitcoin are awarded to the successful miner, other miners will need to check and verify that the figures were correctly derived. To check if some node has executed the required work correctly the one will need a string.
