The double-spending problem persists, however, if two blocks with conflicting transactions are mined at the same approximate time. When servers inevitably disagree on the order of the two blocks, they each keep both blocks temporarily. As new blocks arrive, they must commit to one history or the other, and eventually a single chain will continue on, while the other s will not.

Since the longest more technically "heaviest" chain is considered to be the valid data set, miners are incentivized to only build blocks on the longest chain they know about in order for it to become part of that dataset and for their reward to be valid. Transactions in this system are therefore never technically "final" as a conflicting chain of blocks can always outgrow the current canonical chain.

The total computational power of a decentralized proof-of-work system is the sum of the computational power of the nodes, which can differ significantly due to the hardware used. Larger computational power increases the chance to win the mining reward for each new block mined, which creates an incentive to accumulate clusters of mining nodes, or mining pools.
