What is Satoshi?

The smallest divisible unit of Bitcoin, equal to 0.000001 BTC.

Detailed Definition & Context

Named after Bitcoin's creator Satoshi Nakamoto, one satoshi (sat) represents one hundred-millionth (1/100,000,000) of a single Bitcoin. With 100 million sats per bitcoin, it allows micro-transactions and precise fee estimations.
