<h1>can addresses of input of a single tx be always considered as belonging to same account?</h1>

<p>Above is a sample transaction on bitcoin.
Here, input addresses are </p>

<pre><code>3P2hJg8iRSBExAjd9yQGaazCLPFLeGB3hU (0.88970519 BTC - Output)
35jRUYxAwkqFhGyiGvS6Q4Aqxgcru7m9DM (0.43636859 BTC - Output)

<p>My question is, since these two addresses are in a single tx, can they be considered as coming from same account (or wallet)?</p>

<p>The reason why I ask is I want to extract account-like info because bitcoin world actually has no account concept.</p>
