So I've been running a (pruned) node for about a week. All the status related functions (getinfo, getnettotals, getnetworkinfo etc), as well as wallet operations and all seem to be working ok.

When I'm watching debug.log, I don't see a lot takes place though. I can mostly see the regular UpdateTip messages, and similar "housekeeping" notifications, but not much more.

How can I figure out more about what my node is doing? if it verifies transactions sent from elsewhere, is it logged anywhere? I can see the mempool, that's ok, but is there a deeper level of monitoring that can be done?

ElectrumX docs mention a non-pruning bitcoin daemon is a must.

Is there a way to run Electrum server (either ElectrumX or another project) on a pruned node?

I currently run a pruned node, with the

Code:

prune=550

option set in bitcoin.conf

If I now want to turn my node to be unpruned, what should I do?

Just remove this option from the file and restart bitcoind, or anything else?

I want to set up a server that will receive http requests (using a simple protocol I define) and perform some simple bitcoin related operations, including import of a HD wallet and pushing transactions.

I wonder what is a good way to do it. I will use an NGINX web server to receive the requests and process them with PHP (I'm also comfortable with python, just for background).

As for the operations themselves, I thought about the following options:
- Run a full bitcoin node on the server and send JSON-RPC requests to bitcoind
- Run a full node + an electrum server and send the requests to the electrum server (with electrum dameon)
- Send them to electrum daemon. No full node / electrum server.
- Don't run anything locally (except the web server) - use a third party API, such as of blockchain.com. Problem is I didn't see an api that allows import / restore of a HD wallet.

I assume there are other options I didn't think. I will appreciate your input on this.
