Currently, I am running a full node bitcoin daemon configured to publish hash transactions via ZeroMQ (ZMQ). I've been noticing that, as a subscriber to the hashtx topic, there are both confirmed and unconfirmed transactions being broadcasted. I only really care about the unconfirmed transactions. Is there any way to configure the bitcoin daemon (bitcoind) to just broadcast unconfirmed transactions?
There are long stretches of intermittent time, on the order of a few minutes, when ZMQ is broadcasting confirmed transactions, and this behavior is resulting in a "freeze" like state because no new unconfirmed transactions are flowing through (being blocked by the stream of confirmed transactions coming through).
At my application layer, I can filter out for the confirmed transactions, but still, I'd like to stop it at the source if possible.
On another note, why is ZMQ broadcasting both confirmed and unconfirmed transactions? Does this have something to do with the daemon having to update its local copy of the blockchain?
