Bitcoin

Revision as of 05:04, 19 November 2013

Bitcoin is an "alternative currency" that is generated electronically with no central authority, with a loosely-connected set of network nodes engaged in "minting" coins by solving difficult mathematical computations, validating such newly-created "coins", and storing transactions involving them. This is all accomplished algorithmically.

A bitcoin, and its associated transactions, can be represented in various ways, even including actual physical metal coins if you can believe the picture in the Wikipedia article. A binary format is defined in the Bitcoin technical specs, but archived Bitcoin blocks in the "Block Explorer" site are displayed in a JSON-based format (served as text/plain).
