The term "satoshi" in use on a message board

The satoshi is currently the smallest unit of the bitcoin currency recorded on the block chain.[1] It is a one hundred millionth of a single bitcoin (0.00000001 BTC).[1] The unit has been named in collective homage to the original creator of Bitcoin, Satoshi Nakamoto.[2]

All amounts in the block chain are denominated in satoshi before being converted for display.[3] The source code also uses satoshi when specifying an amount of bitcoin.[4] When displaying an extremely fine fraction of a bitcoin, as in a contemporary faucet, the amount is displayed in satoshi for readability.[5]

As of July 2017, 1 US cent is worth approximately 430 satoshi.

History

The value of a bitcoin in satoshi was decided by Satoshi Nakamoto to be 100 million no later than November 2008.[4]

On November 15, 2010, ribuck proposed that the one hundredth of a bitcoin (0.01 BTC) be called a Satoshi.[6] Four months later he instead suggested that the one hundred millionth unit be called an austrian or a satoshi.[7] The name satoshi caught on, and was widely adopted thereafter.[2]

Usage

Plural

Traditionally, the plural form has been simply satoshi,[8] but the term satoshis is also popular. If the plural form were to follow the rules of Japanese grammar, it may be pronounced as satoshi,[9] or satoshisa.[9]

Symbol

Satoshi is sometimes abbreviated to sat or s, although no symbol has been widely adopted.

The Japanese character シ ("shi") has been proposed as a potential currency symbol for the satoshi.[10] The Katakana symbol サ ("sa") has also been proposed, as it looks more reminiscent of a currency symbol.[11][12] The circled shi (㋛) has been suggested to disambiguate the symbol from the character,[13][14][15] as it is synonymous with death.[15][16] Additionally, the Hiragana shi (し) is a suggestion.[16][17]
