Sending BTC is actually counterintuitive: nothing is truly 'sent.' On the Bitcoin blockchain, there are no transferable tokens or account balance fields. What you own is simply a set of unspent transaction outputs (UTXOs) controlled by your private key. When you 'send,' what really happens is: 1. You use your private key to sign a transaction, declaring that you want to spend certain existing UTXOs; 2. Once the transaction is packaged into a block by miners, all network nodes update the UTXO set—marking the old UTXOs as spent and creating new UTXOs. In other words, there are no 'tokens' on the Bitcoin ledger that can be sent. Its essence is signatures + global state updates. Example: Let’s say you control a 2 BTC UTXO and want to send 1 BTC to Saylor. The transaction will consume your 2 BTC UTXO and create two new UTXOs: • 1 BTC to Saylor’s address • About 1 BTC (minus transaction fees) as change, sent back to an address you control After the global ledger is updated, the total UTXO controlled by Saylor increases by 1 BTC, while the total UTXO you control decreases by 1 BTC (plus fees). The total BTC supply in the system remains unchanged—the fees simply go into a miner’s new UTXO. No physical entity is moved; it’s just a global state update of 'who has the right to spend which outputs,' synchronized through signatures and consensus.
