What Is a Satoshi?
The satoshi is the
smallest unit of the bitcoin cryptocurrency. It is named after Satoshi Nakamoto, the creator of the protocol used in
blockchains and the bitcoin cryptocurrency. The satoshi to bitcoin ratio is 100
million satoshis to one bitcoin. As of Sept. 28, 2019, $1 was worth 12,270
satoshi, according to Coindesk.
KEY TAKEAWAYS
- A satoshi is the smallest unit
of a bitcoin, equivalent to 100 millionth of a bitcoin.
- Bitcoins can be split into
smaller units to ease and facilitate smaller transactions.
- The
satoshi was named after the founder, or founders, of bitcoin, known as
Satoshi Nakamoto.
Understanding Satoshi
Unlike the physical
versions of global currencies, such as the British pound or U.S. dollar,
cryptocurrencies predominately exist in the digital world. Despite this
difference, a cryptocurrency can be divided into smaller units, just as the
pound is broken into pence and the dollar into cents. In the case of bitcoins,
the smallest unit available is called the satoshi.
The satoshi unit is
named after Satoshi Nakamoto, the anonymous person (or persons) that published
a white paper in 2008 that jumpstarted the development of the bitcoin
cryptocurrency. The paper, “Bitcoin: A Peer-to-Peer Electronic Cash System”,
described the use of a peer-to-peer network as a solution to the problem of
double-spending. The problem – that a digital currency or token can be used in
more than one transaction – is not found in physical currencies, as a physical
bill or coin can, by its nature, only exist in one place at a single time.
Since a digital currency does not exist in the physical space, using it in a
transaction does not remove it from someone’s possession.
The satoshi represents
one hundred millionths of a bitcoin. Small denominations make bitcoin
transactions easier to conduct and makes extremely fine transactions readable.
The general unit structure of bitcoins has 1 bitcoin (BTC) equivalent to 1,000
millibitcoins (mBTC), 1,000,000 microbitcoins (μBTC), or 100,000,000 satoshis.
While the exact figure is unknown, it is estimated that Satoshi Nakamoto may
possess 1 million bitcoins, equivalent to 100,000,000,000,000 satoshis.
While not part of a
major currency pair, bitcoins can be converted to and from other currencies.
Bitcoin exchanges exist in order to allow individuals to conduct transactions.
This involves depositing dollars, pounds, or other supported currencies into an
account in one of the exchanges, where the balance can be used to buy or sell
bitcoins and ultimately convert them into other currencies. Just as with the
exchange rates between established currencies, the value of bitcoins will
fluctuate according to supply and demand.
While individuals may
keep a penny or pence in their pockets, physical versions of cryptocurrencies
like bitcoin have not become as mainstream. This is primarily for practical
reasons since the main draw of bitcoin is that it is digital and hard to
counterfeit. Not having a physical presence means that bitcoins are more
secure, even before the blockchain technology is taken into consideration. Another reason for the lack
of physical bitcoins (and satoshi) is that bitcoins are not widely-accepted in
day-to-day transactions.
