There are three "addresses" https://tradeblock.com/bitcoin/tx/6b1c57d98a557b5f578c02f6c386ef049df5890ebddd01d286bf345f47c5cecc

What do you mean by "addresses" (with quotation marks)?

what do YOU mean by addresses without quotation? Not all transactions go from and to addresses.

You said "There are three 'addresses'." So what is the difference between the addresses involved in the transaction and the addresses involved in the majority of the other transactions? (except for they participated in a multisig output)

Are you saying that there are only wallets in bitcoin protocol? If yes, then I understand what you mean.

I have another question regarding the same transaction. http://bitcoin.stackexchange.com/questions/51772/what-does-this-output-item-in-the-result-of-the-call-with-blocktrail-api-mean Would you mind if you answer it? (I find a way to get the addresses, but another issue appeared.)

<p>This is the transaction in concern: <a href="https://blockchain.info/rawtx/6b1c57d98a557b5f578c02f6c386ef049df5890ebddd01d286bf345f47c5cecc" rel="nofollow noreferrer">https://blockchain.info/rawtx/6b1c57d98a557b5f578c02f6c386ef049df5890ebddd01d286bf345f47c5cecc</a></p>

<p>I think it is a transaction having nothing to do with coinbase because there is a prev_out field in the items in the input array. However, there is no field "addr" in the prev_out item, unlike this transaciton: <a href="https://blockchain.info/rawtx/304b90ea66d80652f2473c0b455bfa7775fa32b2de3f170c15bfe8e65c0a7adc" rel="nofollow noreferrer">https://blockchain.info/rawtx/304b90ea66d80652f2473c0b455bfa7775fa32b2de3f170c15bfe8e65c0a7adc</a> 
and most of the other transactions.</p>

<p>Is there any reason for lacking an "addr" field? Could this indicate some malpractice?</p>

If I search by tx_index of that prev_out entry: https://blockchain.info/rawtx/140787227, there is an entry with the same tx_index and same value, AND having the field "addr".
