Package org.consensusj.bitcoinj.signing

Interface Utxo

All Known Implementing Classes:
TransactionInputDataUtxo, Utxo.Basic, Utxo.Complete, Utxo.Signable
public interface Utxo
UTXO info for transaction signing. Immutable and all fields non-nullable.

Non-segwit can be signed without amount, but we're focusing on modern Bitcoin, so we're going to simplify things by making Utxo.Signable mandatory in many methods.
