Definition
Bitcoin is a network designed to settle payments and track balances without a central operator. A paper under the name Satoshi Nakamoto appeared in 2008 and the first block was mined in January 2009. Transactions are recorded on a public ledger and miners around the world reach consensus through Proof of Work.
Key points
- A protocol-level cap of 21 million coins
- New issuance halves roughly every four years

Watch out for
