Let’s talk about a guy named Joe who's into Bitcoin and his setup: - Joe's using a Linux machine. - This is his personal computer where he does everything, from binge-watching shows to handling online banking. - He’s…

Hey everyone, just wanted to share some analysis I did on how the famous power law model has shifted over the years. I can't post images here, so you'll need to click the links if you're interested. Maybe a mod can help…

Anyone know where to find the official details on what goes in the `bitcoin.conf` file and what each option means? From what I’ve seen, almost every argument from the `bitcoin-cli` command can be used in there. But now…

I am curious, if I may ask, why is it so memory hungry? From my limited understanding, while downloading the blockchain it is also validating it. This has to be done one block at a time, because of the nature of the…

I left `bitcoind` running for some hours in a very powerful machine and can confirm that now it is going very fast again, so the bottleneck is something in the Raspberry Pi. In the powerful machine I am running it with…

and `top` is: Also, using `iotop` I get: all the time. This could be the bottleneck.[/code]

It has 8 GB of RAM. ``` $ free -h total used free shared buff/cache available Mem: 7.6Gi 452Mi 79Mi 456Ki 7.2Gi 7.2Gi Swap: 511Mi 324Mi 187Mi ```

So, I'm trying to run a bitcoin node for the first time. I got bitcoin core from the official site. I'm using `bitcoind` on a Raspberry Pi 4 with a Samsung T7 that has about 220 GB free space (just checked a couple…

Just got into running a node. I'm using a pretty basic machine, and whenever I call `bitcoin-cli getconnectioncount`, it usually shows only about 1 to 3 connections, never more than 4. But on my more powerful setup, it…

I just discovered that my system time as reported by the `timedatectl status` command was wrong by 1 hour with respect to my location, because he `Time zone` was set to a nearby city but not my city. Could this be the…

At the moment I just want to setup a node for learning purposes. Why on an external USB SSD? So it is system independent, today I run it in PC1, next week in PC2, and so on. In the end, the `.bitcoin` directory is just…

I was going once more through a `bitcoind -reindex-chainstate` and now I got this: ``` 2025-09-15T16:28:46Z UpdateTip: new best=000000000000000001b2c2c82835d620f320a164d5a2bc76d2f0055587aa6697 height=349842…

It is formatted as ext4. I discovered that if I remove (or comment) `rpcauth=btcusr:78a8kocqo123n3u139b19695ac06401b2f$00e056c84e4981419f8c9829edaaaf9685b50988e12646318945dd9b60f0e165` from the `bitcoin.conf` file, then…

The `.bitcoin` directory is a symlink to the folder in the USB drive. Now it failed during `bitcoind -reindex-chainstate` in this way: ``` 2025-09-13T21:22:28Z connect() to 127.0.0.1:9050 failed after wait: Connection…

This happened again, this time not even unmounting the USB drive. `bitcoind` was running fine since yesterday. I stopped it with `bitcoin-cli stop` and waited until it finished. Time later I started it again (no…

So I'm setting up a node for the first time and I've got the whole blockchain on my Samsung T7 external USB SSD. The node runs pretty well, but about 20% of the time when I stop `bitcoind` using `bitcoin-cli stop`, the…
