Should enter UTXO references (txid + vout) be distinctive in a transaction, and/or be distinctive in a block?
Put one other manner, is it a rule that UTXOs could be consumed piecemeal in transactions and blocks, as long as the full quantity spent is <= to the UTXO’s quantity?
If a transaction was constructed by which totally different inputs referenced the identical UTXO, would the transaction be commonplace or legitimate?
If a block was constructed by which totally different inputs in numerous transactions use the identical UTXO, would the block be legitimate?
In each circumstances, let’s assume that the full quantity consumed is lower than the UTXO complete.
