Title: Do all input addresses in a transaction always belong to same user? Post by: ani4444 on April 11, 2016, 09:11:24 AM Do all input addresses in a transaction always belong to same user?
Eg: https://blockchain.info/tx/a7df580e6f1c6e0ad9627b77295cafd73836e0d7827116d5237fb6c25b60efbe Can it be safely assumed that the following addresses belong to the same user. Code: 18KUnn8L8DhiASGNNJbC5V49MBQTy6uFVu Other examples: https://blockchain.info/tx/c1ce9b849e014fa25d2089493b008e8edcb8f5db42ca40b451700588cb4a71d1 https://blockchain.info/tx/a7df580e6f1c6e0ad9627b77295cafd73836e0d7827116d5237fb6c25b60efbe Title: Re: Do all input addresses in a transaction always belong to same user?

Eg: https://blockchain.info/tx/a7df580e6f1c6e0ad9627b77295cafd73836e0d7827116d5237fb6c25b60efbe Can it be safely assumed that the following addresses belong to the same user. Code: 18KUnn8L8DhiASGNNJbC5V49MBQTy6uFVu Yep. However, you can also verify them here-> https://www.walletexplorer.com/wallet/11e5dada77ed81bc/addresses . You can therefore say that the three addresses(given above) are a part of the same wallet [11e5dada77]. Title: Re: Do all input addresses in a transaction always belong to same user?
