Print Page - Parsing your transactions using bitcointools

TxIn: prev(82df...6428:1) means the second TxOut of transaction 82df...something...6428 (it abbreviates the full 256-bit transaction hash and starts counting at zero).

To see that transaction:

Code:

gavin$ dbdump.py --transaction=82df...6428
1 tx in, 2 out
['TxIn: prev(bfb0...cd16:1) pubkey: 17muZqKMEFqzefsqYhR9vqBjz1jNVcDcbh sig: 71:3044...0201 65:0480...af42']
['TxOut: value: 0.05 pubkey: 1GVgigFDZ9pPLyYwxboEoaSDMDbsBQPVMx Script: DUP HASH160 20:a9f6...9268 EQUALVERIFY CHECKSIG', 'TxOut: value: 66.07 pubkey: 1LsvDRhoMmH5YeZDAxaP5rqwNTp3xFCF3Q Script: DUP HASH160 20:da0b...a345 EQUALVERIFY CHECKSIG']

This looks like bitnickels coins coming out of the Bitcoin Faucet. The transaction before THAT is:

Code:

gavin$ dbdump.py --transaction=bfb0...cd16
1 tx in, 2 out
['TxIn: prev(b1dd...5cd9:1) pubkey: 1MQNsNwRHTu7MWPgFRGRRZfo58jU3RGxJv sig: 73:3046...8501 65:041b...6624']
['TxOut: value: 0.05 pubkey: 1GVgigFDZ9pPLyYwxboEoaSDMDbsBQPVMx Script: DUP HASH160 20:a9f6...9268 EQUALVERIFY CHECKSIG', 'TxOut: value: 66.12 pubkey: 17muZqKMEFqzefsqYhR9vqBjz1jNVcDcbh Script: DUP HASH160 20:4a4e...e0c3 EQUALVERIFY CHECKSIG']

To compute the net transaction value, just add up the values of all the TxOuts; they have to equal the sum of all the TxIns (well, unless there are transaction fees (http://www.bitcoin.org/wiki/doku.php?id=transaction_fee)). So for that first transaction, 66.07+0.05 = 66.12 (which is, indeed, bfb0...cd16:1)
