Running Bitcoin Knots version v25.1.knots20231115 (the latest version of Knots.)

The wallet file I tried adding it to is a brand new one.

When I try to the loadwallet command, it says "Wallet useage is restricted. (code -18)".

I tried to use Sparrow wallet aswell but it looks like it won't import particular addresses.

Running Qt version 5.15.5.
On the console window, when I try the imortaddress command, it returns:
..even though the wallet is loaded.

If I close the wallet and try again, it says:

Anyone know why it's not able to use the wallet?

Regarding the reported 11 million Optus customers who are disconnected in Australia at the moment, I went looking for an app (android in my case) designed to share an internet connection (or leech off someone who is sharing theirs.)

Eg. If I had a working Telstra 4G/5G internet connection and was willing to share it with other phones/laptops/devices that were looking for an internet connection, via wifi/bluetooth/perhaps even 4G/5G. Eg. If I knew that Optus was down and I had a working internet connection and was willing to 'seed' it to say a maximum total of 20 'leeches', 100kbyte/sec each (and/or total 500kbyte/sec), throttle each when 50megabyte hit down to 5kbyte/sec each, disconnect at 100megabyte each let's say.

SmartMesh and RightMesh seem to be nothing-burgers to be quite frank, and searching for 'peer to peer internet' on the google play store didn't show anything suitable as best as I could find.
Too many search results that claimed to be able to do this sort of thing involved tokens. It shouldn't require monies just to use it!
It should be free for anyone to seed or leech as they want. (Any transaction for priority should be btc settled anyway, not some token.)
Ideally it would also allow peer-to-peer data rather than just internet sharing (mesh network) but one thing at a time I guess.

Just interested in the novelty of being able to physically trade a valuable private key, that is locked say for 10 years or 100 years, that can be verified without needing an internet connection, that destroys itself if opened before the 10 to 100 year time has passed. I guess a list could exist to ensure that the used address did not exist anywhere else. But yes still some trust given to the manufacturer I suppose.

OpenDime, SatsCard and Cacascius; yes that's what I was looking for. Thanks

Sorry, I think I meant Time Lock instead of HTLC's.
So that anyone owning or receiving this card device could check that the address in it could not be spent for like 5-10-20 years.
Personally I wouldn't bother with it, but I do find it an interesting application for bitcoin being used as a physical medium (like a fifty dollar note or a 1 gram bar of gold).

What are the names of some of these devices again? I'm struggling to find them:

A year or three ago I came across various devices that had a private key inside them, holding a certain amount of bitcoin.
I think they ran off external electro-magnetically induced power (like a credit card) to power its chip, which could prove ownership of its key to an external device that had a new-enough copy of the blockchain for verification.
Like a hardware wallet it would destroy its key if an attempt was made to get inside it.
I think they held a HTLC balance for proof of it being able to 'hold its value'.
I forget if they had a way to prove that a particular card was the only card that held that key. (I can't think of one; what would stop the manufacturer reusing the same key on more than one card? Possibly some way on the lightning network or similar? I've no idea.)

I searched for half an hour and failed to find them.
Anyone remember some of their names?

Thanks

I don't have a 32-bit machine handy to find out by trying, and I've been unable to find out from the versions of Bitcoin Core which one was the last .tar.gz version that will run on a 32-bit intel machine?

Thanks

Well if it's half a kilobyte that should be doable in 20 minutes. Over an hour might start to get masochistic  (He says taking 2 years to reply..)

Regarding pooya87's screenshot above, (Tools > Load transaction > From text) I'm curious to see what this looks like, and how long it is.

On electrum's website (https://electrum.readthedocs.io/en/latest/coldstorage.html), they don't mention the text option; they just say "" which assumes nothing nasty is running on the 'cold' machine looking for an exit hole, which doesn't sound very pleasant.

Thanks!

Any thoughts on how you'd find them? (Assuming that all you knew was their key/s and address/es.)

Good point, I guess the authority who is reported to might be able to ask exchanges if any of their customers withdraw to specific addresses.

Yes, I'm assuming that they'd still have their key in question.

Yes; they'd not want to lose it.
Yes; you'd not want to steal it, but would feel awkward having discovered that their valuable key isn't safe.

What would you do if you managed to come across someone else's private key and it's worth an amount that most people would 'prefer not to lose', assuming you have no [idea who it belongs] to or [location clues]? Eg. Sweeping through common books' text for BIP39-based keys.

I suppose you could send a dollar's worth to a different address and hopefully they'd get the hint.

I dare say that in many situations, an aircon running on heating would be a better heater than an old miner, because of typical COP, eg. using 1000 watts to do the same amount of heating as a 3000w fan heater / oil heater / miner. Not to mention floor space usage / noise.
Eg. a miner that's 96 TH/s, 2400 watts, 1.5% pool fee, would lose about $3.14/day @ $0.15/kwh power cost, compared to a small aircon using say 800 watts to pump 2400 watts running 24/7 would cost about $2.88/day (of course if your aircon never stops running, it's undersized.)

Modest/excess wattage spent on lotto mining sounds good.

Sorry, I should have said: sending >0.04 BTC to the bc1 bitcoin address that Breez creates in order to set up the lightning wallet.

Just wondering what happens if you send your Breez wallet more than 0.04 BTC, as it says to send "up to" that amount.

Wasn't able to find out what they do / what happens / doesn't happen if you send more than 0.04 BTC to it, as I didn't see it mentioned on their FAQ page.

Can someone tell Putin to sell his gold for btc? Thanks.

When I produce a QR code to show a receival address in Bitcoin Core, it comes up with both lowercase and uppercase letters in the address. (Core v0.18.0, Qt v5.9.7, old, I know...).

I saw a bitcoin address on a video, and all of its letters were in capitals.

Is this common? Perhaps they made it this since it was in a video, making it harder to "copy & paste"?

Looked a bit weird.
