I’m attempting to seize all of the changed transactions. I’ve complied Bitcon Core with tracing enabled and take heed to the mempool:changed as steered on this query.

This methodology works as anticipated and I can get the changed transactions. Nonetheless, in some instances (about 20% of all of the transactions I seize) the tracepoint alerts me of the transaction being changed, however then I’m not capturing the substitute of that transaction.

I can consider two the explanation why that is occurring:

1. It could possibly be that a few of the replacements don’t enter my mempool. But when that’s the case, how does the tracepoint is aware of that the transactions is being changed? Additionally, it’s bizarre that this might occur with so many transactions (20% as defined earlier).
2. The second possibility is that the script that course of the transaction shouldn’t be contemplating some instances, which leads to dropping transactions. The script is a modified model of this instance. I’ve modified it so I can seize the kids of the changed transactions as effectively. The information I collect with this script is later saved in a pkl file, which is why it has a shared listing.

I do not know why I’m dropping so many transactions, and I used to be questioning if somebody might assist see what I’m doing improper.

Listed below are the modified capabilities:
