Part 6/11:
To spend Bitcoin, your wallet collects UTXOs, signs a transaction with your private key, and broadcasts it to the network.
The blockchain network verifies the signature using your public key, confirming the transaction’s validity.
How Wallets Find and Spend Your Bitcoin
Your wallet scans the blockchain for UTXOs tied to your public keys.
When you spend Bitcoin, the wallet signs the transaction with your private key, producing a signature.
The network validates this signature before confirming the transaction.
“Your wallet is like a cashier that signs off on transactions and tells the network that you own those UTXOs.”
