Node is latest version, fully synced, pruned.

It just get's weirder: in bitcoin-qt -testnet it shows available balance of 0.01 tBTC, but in Send > Inputs, there is nothing, quantity = 0, amount = 0.

*Testnet BTC Core Wallet*

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

What's going on?

ETFbitcoin:

I am able to propagate transactions when using sendrawtransaction, it's just the command sendtoaddress and bitcoin-qt never propagate. Disabled my firewall, same result.

At least I have a work around.

Thanks

Wasabi shows the QR code for the address, but right next to that for reference it shows the public KEY for that address.

Since your counterparty is scanning your screen for the address QR code, they can get that public key. also. Obviously that can't steel your coins with that, just wondering if there a some negative privacy effects to them having that public key before you ever spend those coins to the network and reveal the public key.

crairezx20:
Right, so normally, your counterparty only knows that's address' pub key along with the rest of the network when you spend from that address.

I've heard how this provides a little bit of extra protection from the threat of future quantum computing, because if you spend from an address only once, then the network only sees that pub key for a few minutes in the mempool before the next block is mined ontop of it.

I'm wondering if there's any other privacy/security concerns coming from your counterparty learning your address' pubkey before you spend from it (besides a little extra protection from the tiny threat of them having having access to future quantum computing). 

and yes, I understand the basics of why mixing is important.

Bitmax:
1. The testnet address I've been trying to get tBTC core to send to is my tBTC mycelium app. However, I've now found that both Wasabi Wallet, and an online testnet faucet also reject the bech32 testnet address created by my phone's mycelium tBTC app. (So that's on you, Mycelium).

2. I determined that my tBTC core fails to propagate if I use
$ sendtoaddress [address] [amout of tBTC]
but, if I use:
$ sendrawtransaction [raw_transaction]
then that propagates right away.
Interestingly, the same failure to propagate occurs if I use bitcoin-qt -testnet.

Any chance this is due to my Linux firewall settings?

My bitcoin.config has already been nearly identical to what you've recommended:

testnet=1

listen=1
server=1
proxy=127.0.0.1:9050

[test]
prune = 5000
regtest=0
dnsseed=0
upnp=0
setgenerate=1
blocksonly=1

addnode=104.237.131.138
addnode=151.80.205.132
addnode=192.155.82.123
addnode=74.220.255.190
addnode=80.100.203.151

maxconnections=15
minrelaytxfee=0.0001

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.

Ranochigo:

Just used an online testnet transaction broadcaster with the raw data, and it has propagated successfully. Any other ideas why my node couldn't do it on it's own?

Here's another symptom: when I tried to send to testnet bech32 addresses (staring in "tb") core tells me "error code -5, invalid address." even though  I created the address with testnet mycelium on my phone and am 100% certain I entered the address correctly into core.
 

Ok, that's good to know. Any idea what would cause my node to be able to receive tesnet transactions but not be able to propagate its own?

BitMaxz: I have core configuring to run in Testnet and it shows this when I run $ bitcoin-cli printtoconsole. These are indeed tesnet coins I'm trying to send to a testnet address.

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

n2eMqTT929pb1RDNuqEnxdaLau1rxy3efi
 
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.

To all:

I'm able to see the label on both laptop and phone by creating a receive request in bitcoin-qt with something written in the "message" field. When I scan the resulting QR code with mycelium on my phone, it labels the transaction with that message. I guess that's all transferred through extra fields in the QR code, and not part of the address itself, so that's why it can't be seen on a block explorer. Thanks!

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.

Thanks!

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,
