<p>Yes, You could use <code>walletnotify</code> in your <code>bitcoin.conf</code> file.</p>

<p>This option will execute command when you receive a transaction.</p>

<p>for example in your bitcoin.conf</p>

<pre><code>walletnotify= curl http://127.0.0.1/callback.php?transaction=%s
</code></pre>

<p><em>Please make sure that you've curl installed.</em></p>

Listening to mempool unconfirmed transaction won't harm your server performance if you are using this server for other purposes you can get another server for these jobs.

<p>I understand that using json-rpc to listen for all transactions is a bad idea due to performance, but bitcoinj is able to do it. In reality bitcoind is parsing all transactions under the hood when it forwards them. Is there any way for bitcoind to notify me when it sees a new transaction (not paying to an address in the wallet)?</p>

<p>Surely its is able to notify other peers, so why not me?</p>

<p>One solution I am thinking of is running connecting a bitcoinj node to my bitcoind and then using that to listen to transactions.</p>

<p>Another solution is to just listen for blocks and lose the ability to see zero conf payments.</p>
