Proof of work

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.

Block Chain

Multiple blocks can all have the same block height as is common when two or more miners each produce a block at roughly the same time This creates an apparent fork in the block chain as shown in the illustration above. When miners produce simultaneous blocks at the end of the block chain each node individually chooses which block to accept.
