Recently I decided to switch from using listunspent in my code to listsinceblock for processing transactions. The information I used to receive from listunspent was in the format of:
{'account': 'Test', 'vout': 0, 'txid': '0106719077ecf117f52b4b17cec68f8e0580603f04abc9f98e053ff9689c0562', 'amount': 0.01, 'confirmations': 5129, 'address': 'mvPFEtQKyAWS8ixQBSGS8hPPMhrVRNVTmy', 'scriptPubKey': '76a914a314b4516faf67360e753a6dfd1fc668ea90e98c88ac'}
The information I receive from listsinceblock is in the form of:
{'category': 'send', 'account': '', 'fee': 0.0, 'blockhash': '000000009e131e0f2f5f8b3b1485622cb1a39a94bbb4aac43bca291fc7e21090', 'blockindex': 20, 'walletconflicts': [], 'time': 1392137346, 'txid': '00b0ebf36eb216e1e772b10171c86a45ddf073cf9b4bb8b204a62477ea51a75f', 'blocktime': 1392138920, 'amount': -1.0, 'confirmations': 64795, 'timereceived': 1392137346, 'address': 'n18poNZrLTNHQMFHj89A6B3ukprGMQu6nN'},
{'category': 'send', 'account': '', 'fee': 0.0, 'blockhash': '000000009e131e0f2f5f8b3b1485622cb1a39a94bbb4aac43bca291fc7e21090', 'blockindex': 20, 'walletconflicts': [], 'time': 1392137346, 'txid': '00b0ebf36eb216e1e772b10171c86a45ddf073cf9b4bb8b204a62477ea51a75f', 'blocktime': 1392138920, 'amount': -2e-08, 'confirmations': 64795, 'timereceived': 1392137346, 'address': 'mtT9kuEYE6VtGH3Wz3SvPJaBNS9eJsNTbp'},
{'category': 'receive', 'account': 'Test', 'blockhash': '000000009e131e0f2f5f8b3b1485622cb1a39a94bbb4aac43bca291fc7e21090', 'blockindex': 20, 'walletconflicts': [], 'time': 1392137346, 'txid': '00b0ebf36eb216e1e772b10171c86a45ddf073cf9b4bb8b204a62477ea51a75f', 'blocktime': 1392138920, 'amount': 1.0, 'confirmations': 64795, 'timereceived': 1392137346, 'address': 'n18poNZrLTNHQMFHj89A6B3ukprGMQu6nN'},
{'category': 'receive', 'account': 'Test', 'blockhash': '000000009e131e0f2f5f8b3b1485622cb1a39a94bbb4aac43bca291fc7e21090', 'blockindex': 20, 'walletconflicts': [], 'time': 1392137346, 'txid': '00b0ebf36eb216e1e772b10171c86a45ddf073cf9b4bb8b204a62477ea51a75f', 'blocktime': 1392138920, 'amount': 2e-08, 'confirmations': 64795, 'timereceived': 1392137346, 'address': 'mtT9kuEYE6VtGH3Wz3SvPJaBNS9eJsNTbp'},
The latter lacks vout for 'category': 'receive', which means it is impossible to use just that data to uniquely identify a transaction output for processing. If someone created a transaction with 2 outputs to the same address and amount, those would essentially produce 2 identical entries for listsinceblock.
I would like the vout parameter added to the listsinceblock output to make its responses more like listunspent for consistency.
