The Transaction

Bitcoin transactions consume Inputs (UTXOs) to create new Outputs. Any difference is the Miner Fee.

How Bitcoin Transactions Work:
  • Inputs are unspent money you received previously (UTXOs).
  • Outputs are new checks you write to other people.
  • The difference (Input - Output) is the Miner Fee.
