In order for a block to be accepted by network participants, miners must complete a proof of work which covers all of the data in the block. The difficulty of this work is adjusted so as to limit the rate at which new blocks can be generated by the network to one every 10 minutes. Due to the very low probability of successful generation, this makes it unpredictable which worker computer in the network will be able to generate the next block.

For a block to be valid it must hash to a value less than the current target ; this means that each block indicates that work has been done generating it.

Each block contains the hash of the preceding block, thus each block has a chain of blocks that together contain a large amount of work. Changing a block which can only be done by making a new block containing the same predecessor requires regenerating all successors and redoing the work they contain. This protects the block chain from tampering. The most widely used proof-of-work scheme is based on SHA and was introduced as a part of Bitcoin.

Let's say the base string that we are going to do work on is "Hello, world! Finding a match for "Hello, world! Bitcoin automatically varies the target and thus the amount of work required to generate a block to keep a roughly constant rate of block generation. In Bitcoin the hash value is also used as a reference to the block itself, so somebody might say that their transaction has been mined into block with hash c3af42fcf1fdcfaffadf7cc52eae12dcd4e9. The header of a block contains the Merkle tree which depends on the included transactions.

This includes the generation transaction, a transaction "out of nowhere" to our own address, which in addition to providing the miner with incentive to do the work, also ensures that every miner hashes a unique data set. Distribution of nonces and hashes. It also makes it difficult for a user or pool of users to monopolize the network's computing power, since the machinery and power required to complete the hash functions are expensive.
