<p>I think what you are looking for is <strong>walletnotify</strong>. You can set on bitcoin.conf file.</p>

<p>For example</p>

<blockquote>
  <p>walletnotify=/home/process_tx.sh </p>
</blockquote>

<p>That will call <code>/home/process_tx.sh</code> passing as parameter the transaction hash
Or you can also run bitcoind with using -walletnotify</p>

<blockquote>
  <p>bitcoind -walletnotify=/home/process_tx.sh</p>

As far as I understand, `walletnotify` only notifies of transactions made to the address that belong to that wallet. I'm interested in collecting all transactions that are broadcasted.

In that case, you should use ZMQ as sugest by @Andrew Chow

<p>You can use the <a href="https://github.com/bitcoin/bitcoin/blob/master/doc/zmq.md" rel="nofollow noreferrer">ZMQ</a> interface to receive a ZMQ notification when a new transaction is received. You can have it give you the txid, the raw transaction, or both.</p>

<p>With <code>getrawmempool</code> it gets me txids, however it just dumps the whole mempool on me. This isn't convenient if I want to quickly detect new transactions. Is it possible to only get newly broadcasted transactions? </p>

<p>Is there another way to sort of stream them from bitcoin-core into my program?</p>

Is there another way to sort of stream them from bitcoin-core into my program?

You can use the [ZMQ](https://github.com/bitcoin/bitcoin/blob/master/doc/zmq.md) interface to receive a ZMQ notification when a new transaction is received. You can have it give you the txid, the raw transaction, or both.

I think what you are looking for is **walletnotify**. You can set on bitcoin.conf file.

For example

> walletnotify=/home/process\_tx.sh

That will call `/home/process_tx.sh` passing as parameter the transaction hash
Or you can also run bitcoind with using -walletnotify

> bitcoind -walletnotify=/home/process\_tx.sh
