divisible, which gold is not. But it is not just one computer trying to solve this problem, there are thousands or millions of computers chugging away at this and communicating back and forth. Where do bitcoins come from? And in fact, most of these purchases will be made online where the time between a purchase and the shipping of the product will make waiting for confirmations a non-issue. For merchants, its good too since the fees to accept Bitcoin are a lot less than Visa fees. On the other hand, like credit cards, there is an acceptance process before the person being paid can be certain the transaction has taken place. If you own or trade stocks, you are using digital money. This is to keep Bitcoin from becoming inflationary and to keep them valuable. On the other hand, one tool governments use to overspend is to increase the money supply, decreasing the value of money (inflation) which makes the value of what the government owes less and, therefore, easier to repay.
These checks and balances make it difficult for anyone to manipulate Bitcoin. Once a block with that transaction is solved, then it is part of a public record. It works like this: The math problems I talked about as being a way to mine bitcoins also are collecting records of the transactions that have been taking place and weave them into the math of that problem. When people saw them a way to buy or sell things, they began to have value.

And, as you know, they all charge their fees and have all sorts of conditions and penalties, usually written in micro-printing on a form no one takes the time to read or understand. The core innovation that makes Bitcoin special is that it uses consensus in a massive peer-to-peer network to verify transactions. The reason that Satoshi set it up this way is that if all the bitcoins possible were released all at once, then he would own them all and there would be no reason for anyone to want them. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively to the block chain. In this case, the majority opinion wins. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. All of these computers communicate together to make sure that there are no contradictions or inconsistencies.
