Bitcoin is digital money that moves directly from person to person without a bank in the middle. The blockchain is the shared ledger that records every transfer.

  • Transfers are grouped into blocks; each block carries a digital fingerprint (hash) of the previous one, forming a chain.
  • Miners compete to add blocks through proof-of-work and receive newly created coins; total supply is capped at 21 million.
  • A new block is added about every 10 minutes on average.
  • Transfers cannot be reversed, Bitcoin is not an official currency, and its price can swing sharply.
