Bitcoin works through the collaboration of computers, each of which acts as a node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of transactions, called a blockchain, without central oversight.
The font consists of only the Bitcoin symbol (₿) used in the glyph for the capital letter B. The text "BTC" can be entered and styled with this font, causing it to be replaced entirely with just the symbol on those systems that support this font, while on other systems the text "BTC" is retained.
Since the birth of Bitcoin, a large number of logos and symbols have been introduced. The most popular is a bold falling serif B, intersected by two vertical dashes à la U.S. dollar.
