Bitcoin is highly divisible, which is essential for anything meant to work as money. A single bitcoin splits into 100,000,000 satoshis, so one satoshi is 0.00000001 BTC. The unit takes its name from Satoshi Nakamoto, the pseudonym of Bitcoin's creator, whose real identity has never been established. Just as a pound divides into pennies, a bitcoin divides into satoshis, which are frequently shortened to sats in everyday conversation.
This divisibility settles a worry that stops many beginners in their tracks: you do not need to buy a whole bitcoin. Because each coin breaks into a hundred million tiny pieces, you can buy and send fractions worth just a few pounds, and small amounts are often discussed in sats rather than in long decimals of a bitcoin. Some enthusiasts even talk about stacking sats as a way to describe accumulating small quantities steadily over time.
For practical purposes, satoshis are simply the small change of Bitcoin. Network fees, tips and micro-payments are naturally expressed in them, and thinking in sats can make the numbers feel far more intuitive than squinting at a long string of zeros after a decimal point. It is a small piece of vocabulary that quickly makes the whole system easier to reason about.
Key takeaways
- A satoshi is bitcoin's tiniest unit, one hundred-millionth of a single coin.
- It is named after Satoshi Nakamoto, Bitcoin's pseudonymous and still-unknown creator.
- Because of this divisibility, you can own and send tiny fractions of a bitcoin, not just whole coins.
Satoshi — часто задаваемые вопросы
How many satoshis make up one bitcoin?
Exactly 100 million. One satoshi is 0.00000001 BTC, which makes bitcoin highly divisible. This is precisely why you can buy a small fraction of a bitcoin rather than needing to purchase an entire one to get started.
Who was Satoshi Nakamoto?
It is the pseudonym used by Bitcoin's creator, who published its design in 2008 and has never been identified. No one has verifiably proven to be Satoshi, and the true identity remains one of crypto's most enduring mysteries.
