Bitcoin's PoW is very similar to the challenge

candidate block filled with transactions. Next, the miner calculates the

hash of this block's header and sees if it is smaller than the current

_target_. If the hash is not less than the target, the miner will modify

<em>target</em>. If the hash is not less than the target, the miner will modify

the nonce (usually just incrementing it by one) and try again. At the

current difficulty in the Bitcoin network, miners have to try

a huge number of times before finding a nonce that results in a low
