*Testnet BTC Core Wallet*

getbalance says I have over 0.01 tBTC, but listunspent gives me the empty set: [ ].

What's going on?

I've noticed that when you generate a new address in Wasabi, it shows the address' public key next to the QR code. This gives your counterparty an easy opportunity to take a picture of that public key.

Obviously one person seeing one public key isn't the end of all your privacy, but (extra quantum protection aside) is there any privacy and/or security disadvantage to your counterparty learning the public key of the address they're sending to?

Thank you

Is the bitcoin core reference wallet HD?

or if I run:

$ bitcoin-cli backupwallet

is it only saving my private keys that I have used thus far, and is not backing up my private future keys?

Thank you.

My btc core node (pruned) can receive transactions, but not send them. I've tried to send around a 1000 sats with over 3,000 sats in fees, to the testnet faucet address

and when I type

$ bitcoin-cli listtransactions

I can see the transaction, but it has had zero confirmations for hours, and I when I enter the txid in a testnet block explorer, there are no results.

Do I need to open port 8333 on my router (i.e., have inbound connections) to be able to broadcast transactions?

Thank you.

When I sent myself testnet coins from my phone to my computer, I added a transaction label. When I look at the transaction in bitcoind, I can see the label but when I look at the transaction in a block explorer, I don't see the label.

Are the only people who can see transaction labels the sender and the receiver?

Thank you.

Can someone please point to documentation concerning the trust field (i.e. the field that says "+0 / =0 / -0" for new profiles") for Bitcointalk.org profiles? I've searched for documentation besides what you get just by clicking on the word "trust", but can't find anything.

How is the trust used? I get the impression people use this site as platform for buying/selling in addition to just posting questions and answers?

Thank you,
