eBay has tons of good deals on used laptops. Just check the seller ratings.

But how long do refurbished ones really last? Aren’t they bound to break faster than new ones?

Your perspective is really insightful! A used laptop with a decent SSD is a good idea.

What you said about Linux makes sense. Most devs work in Linux unless they’re specifically targeting Windows. He’s not selling this, just made it for fun, so I get why he went with Linux.

I’m running a Bitcoin Core node headless on a couple of Raspberry Pi 4B units with 8 GB of RAM. I also run Electrs or Fulcrum as personal Electrum servers. Bitcoin Core plus Electrs just fits on a 1 TB SSD, but for…

Hold on, before I get too caught up in this… how effective are your methods? Like, how long would it take to recover, say, 5 or 6 missing words from a 12-word phrase?

Are you sure Bitcoin Core is running under the same user when started from systemd vs command line? It’s a common issue. Also, check if both instances are actually reading the same bitcoin.conf. Have you tried using…

Been thinking about this more. Honestly, I see it as a big setback that pools can fork like this. If that happens, how do they decide which branch to stick with? It’s like a gamble since mining is all about luck with…

Yeah, decentralization sounds legit. I mean, I saw that block 912721 was in both UpdateTip events, same hash. But why the need for a second UpdateTip? It shouldn't have mattered with the fork of 912722. 912723 chose the…

I noticed something odd while checking out the block explorer recently. A few mining pools seem to be forking their own blocks. Totally didn’t see this happening on my node though, so not sure what's going on.

Exactly! When you create a watch-only wallet in Electrum, it warns you. You need those private keys safe somewhere else, or you’re not in control of the coins in there. Remember, coins are on the blockchain; wallets…

USB storage? Not a fan. They’re usually slower and less reliable than internal drives. With Bitcoin Core on Tor, no need for port forwarding. My nodes have no issues with incoming connections via Tor.

I need my connection stable for work, so hoping for a solution. Let me know if the QoS helps.

Sounds like you’re using a watch-only wallet. Those don’t have private keys, so you can't sign any transactions. How did you create that wallet? Do you have access to the wallet with the private keys? Any recovery words?

The main way to get testnet coins is through those faucets. Or, you could ask a friend for some or even send coins from one address to another if you have them. But honestly, why do you need multiple addresses for…

Forget about Blockchain.com. Get a live Linux system and try to find the private key using Ian Coleman's tools.

Yeah, I didn't consider that chainstate might have been bigger back in the day. Thanks for that perspective! My Core nodes are set to allow other nodes to pull as much as they want, but I haven't seen any crazy pulls.…

You can speed up the initial block download for sure, but it won't be smooth all the time. Use SSDs for your chainstate. HDDs can work, but not great unless you have a lot of RAM to handle dbcache settings. Aim for a…

Solar storms can wipe out power. The Carrington Event was a warning. Who knows what larger storms could do.

I doubt a full shutdown is even possible. The world relies too much on the internet and power. Miners might just face high electricity costs instead.
