BTC

Peer-to-peer, scarce, decentralized money

Bitcoin is the first digital currency without a central authority. Launched in 2009 from Satoshi Nakamoto's whitepaper, it has run continuously since then with a hard cap of 21 million units. Every block is validated by a global network of nodes; no entity can censor transactions or alter the issuance.

Units

1 BTC = 100,000,000 satoshis. A satoshi (sat) is the smallest unit — Bitcoin's penny.
