Output
blockchain
A spendable unit of cryptocurrency created by transactions; referenced as an input when later spent.
- Also known as
- UTXO
1.basic
Outputs are discrete chunks of value created by transactions. Each output can be spent once by referencing it as an input in a future transaction that satisfies its locking script.
2.wallet-use
Wallets manage sets of outputs, not a single account balance. Coin selection chooses which outputs to spend, and good wallet behavior avoids creating tiny uneconomical outputs that may cost more to spend than they are worth.
