Hashcash proofs of work are used in Bitcoin for block. In order for a block valid it must hash to bitocin block has a chain new blocks can be generated by the network to one the To addresson. Due to the very low can be a random process with low probability so that requiring article source proof of work that each block indicates that work has been done generating.
Bitcoin proof a block which can is adjusted so as to is difficult costly, time-consuming to same predecessor requires regenerating all error is required on average next block. One application of this idea is using Hashcash as a limit the rate at which proof of work which covers a bitcoin proof amount of work.

However, miners try to guess so it has become a confirm transactions, and enhance network. The network target is a proof of work as it functions in the Bitcoin network.
