Traditional electronic payments rely on trust in financial institutions to mediate disputes. This increases transaction costs, limits the minimum practical transaction size, and eliminates the possibility of small casual transactions.
Bitcoin is a peer-to-peer electronic cash system that allows online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required.
The proof-of-work system involves scanning for a value that when hashed, begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
