Bitcoin's peer-to-peer method for clearing payments means that the currency's "books" are inherently open. As traffic grows, more Bitcoin users may use lightweight clients, and full network nodes may become a more specialized service. When two blocks are found at the same time, miners work on the first block they receive and switch to the longest chain of blocks as soon as the next block is found.
