    <div class="sphx-glr-thumbcontainer" tooltip="Bitcoin keeps no balances. Value lives in coins, the outputs of earlier transactions, each locked to an owner. A payment consumes whole coins as inputs and creates new outputs: one to the payee, usually one back to the payer as change. Whatever is not assigned to an output goes to the miner as a fee. A coin can be spent once; a double spend is two transactions consuming the same coin.">
