I don't have enough money in to justify a hardware solution like Trezor or Ledger yet. As far as the 12 mnemonic words go, I do use that for wallet backup.

I'm still new to this stuff. I already managed to send a small amount of money into a wallet address with no private key. 

The thread was inspired by me wanting to setup a miner that is hopefully fast enough to get me accepted into a mining pool. I'm currently shopping for an ASIC solution. In the meantime, I can do GPU (I think) with a software I downloaded.

I failed to follow instructions properly. I was having issues getting the exact address. However, I found a better solution, I think. I found BlueWallet on the App Store. I was able to use the xpub key to import a watch only wallet into it. This is actually the functionality I wanted on the iPhone. I haven't tested sending funds with bitcoin-cli yet, but if sendtoaddress works (https://bitcoincore.org/en/doc/24.0.0/rpc/wallet/sendtoaddress/) I'm golden.

BlueWallet also works with the paper wallet generator earlier in this thread. I can set it up for receive only or use the private key to make it a hot wallet. It defeats the point of paper wallets, but it's nice to have options. I grabbed the source from GitHub so I can learn from it.

Thank you for your time and patience.

I used my phone app to transfer funds to the miner wallet that I thought I exported correctly. However, the funds are not showing up in getwalletinfo. I'm not sure what I did wrong. Wrong command perhaps? Bad export? I'm running a rescan right now, but I wouldn't have thought that necessary.

I'm not sure what info to provide other than I've been following the recommended steps above. I have at least had success with a paper wallet (bitaddress.org.html running locally from the GitHub repository (gh repo clone pointbiz/bitaddress.org)).

Since I'm here and it is partly on topic, what is the recommended usage for paper wallets? Reuse or throw away after spending all funds?

Real money goes to a "paper wallet". Secret keys aren't even on an electronic device and are kept separate.

 

Thanks! I have a bit of confusion on a point. I was able to generate a 12 word mnemonic and that showed a QR code which I was able to scan in and import with my iPhone wallet. The words match fine. But the extended public key on the phone does not match the one in the Mnemonic Code Converter. Both have the xpub prefix. But from there they don't match. I was under the impression that they would and that I failed to follow instructions properly.

Any further help or assistance would be greatly appreciated.

I would like to do a small test transaction. It would be nice if the funds showed up on my full node

The computer is on a private IP network. So the only way in, so far as I know, is via the connection used by Bitcoin Core. Although it does get access to the outside world through other services such as NTP and whatever the heck Apple uses for software update.

My security plan, if it can be called that, is if any BTC of significant quantity is successfully mined, it gets moved into a cold storage wallet.

Anyone getting shell access to that machine would have a field day as they are now on my private LAN.

Out of curiosity, what known attacks are there against a hot wallet on Bitcoin Core? I presume they are fixed as they are discovered.

bitcoin-cli dumpwallet gives the same error.

No transactions have been made to or from this wallet yet. I created it with Bitcoin Core. I'm hoping to use this wallet for mining. I also want a copy on my iPhone in the Bitcoin.com wallet app. I don't know what's broken here. I compiled from GitHub source. No GUI.

Any ideas?
