The only advantage of a Sybil attacker in Tor is that they can create an infinite number of onion addresses for free, which would come at a cost to do with IP addresses. I cannot think of any other advantage. If you're being Sybil attacked in a Proof-of-Work blockchain system, it means the attacker owns a good percentage of the hashrate, because otherwise, your client would stuck on a block height, and you could notice that you're being Sybil attacked.

In the case of an attacker who has the incentive and amount of money to Sybil attack, the cost to acquire a few IP addresses would really be negligible.

Is it better for the monero network to run a node over clearnet or tor? I've heard running over tor increases chances of a sybil attack

Yes, it was actually slowing down my whole internet connection at home. I was trying to use watch some videos on YouTube and it was very slow.

What saved me was:

1. I changed in-peers and out-peers to much lower values.
2. I used the limit-rate to limit the up and down rate.

I think specifically I have set them to:
in peers = 8
out peers = 20
limit rate = 2048

I am not sure about the specific issue that you mention though...

I just tried installing a Monero full node on my Raspberry Pi 4 today. It didn't go well. Installation is spot on, and I'm glad that I could use the Monero GUI (which is officially supported by Monero dev team), but it's just too resource-requiring for a Pi that already runs a Bitcoin node.

The ugly part wasn't synchronization. That took a week on my HDD, and it's a reasonable amount of time given that Monero has an exponentially larger spend index size. The ugly part is that it's faster to run a pruned node on my main computer (with no running in the background) and open it up whenever I want to make a transaction, than connecting to my Raspberry Pi via remote node. It was trying to calculate the automatic fee, and had stuck...

Does it go slow to you too?

It's the Raspberry Pi 4b 8GB RAM as I mention in the first tutorial.

To be honest, I chose the RPi because it was very cheap, but if I had plenty of money I would probably choose an NUC. The 8GB RAM sound sufficient of course.  The IBD took 72hrs for me.


Yes I will go with CLN and I will definetely take a look at it.

Which model? My experience with Pi nodes was... mediocre, to say the least, in the (now somewhat distant) past. Especially due to initial block download time. In my guide, I showed that you basically really want 8GB of RAM.

I highly recommend Core Lightning (as used in my guide). You can take my guide as a starting point.

Yeah mine too. I thought of running all the essentials on a rapberry pi. The only thing I haven't yet figured out is whether I will make it a Lightning node as well. If I do, I will probably do it using CLN and not LND. But I need to find the necessary time, otherwise I will never make it.

Thanks, I try to keep it updated, as seen in the changelog.
I'll update it again this week; it's been 6 months..

My guide is more focused on setting up a dedicated machine that runs all (and only) the Bitcoin 'essentials'.

No, absolutely not. I have just forgotten about it.  I am adding it now! I will run sudo du -sh on each directory and I will update the posts.


Very nice guide. Congrats to you too.

Looks great now, super comfortable to navigate. So you decided against something like a little 'disclaimer' or information regarding disk utilization at the top of the Bitcoin Core, Electrs and Monero guides?

I think with Core and Monero people will find the information online easily; just Electrs was surprising to me when I first installed it. Maybe I shall add information about that in my own guide..

I will definetely do both, in fact the first suggestion is very useful. That way it is more apparent that the posts are part of a series, otherwise, one could miss it. Thanks

True, but I meant a full index, something like:

That's very good to know, thanks! I'd add it to the individual guides too, so users would know what they're 'getting into' before installing every one of these.

Hey n0nce.

So:

There are. Just check on top of each post. And there is also a link to the next one on the bottom of each post.

So every post is linked with the previous and the next one.

I just realized that it's a series; maybe would be a good idea to add backlinks to all or at least the first tutorial to the top.

Yeah, I think as a user I'd like to see how much RAM & CPU, but maybe most importantly how much disk space, every additional piece of software uses. From my own experience, it should be just Bitcoin Core and Monero taking up most of the disk space.

Hello.

If you are interested in the hardware that I use, you can head back to the 1st tutorial of the series, in which I install bitcoin core on the same machine.

If you want to know how much RAM and CPU the node uses, then I will definitely make sure to update the original post.

In fact it is interesting to see how much RAM all of the apps I have installed in the series use (Bitcoin Core, Electrs, Sparrow, Monero)

It would be interesting to add a few details in terms of requirements (computing and storage) to the top of the guide.

I remember fondly the days when people downloaded Bitcoin Core, back when it was the default wallet to run on your daily driver laptop, coming back a few days later to 'full hard drive' notifications from their operating system..

Especially, when someone is already running Bitcoin Core on the same machine and maybe even chose their SSD to fit a certain number of years worth of Bitcoin blockchain on it.

I just remembered that I forgot to write about allowing incoming connections on 18080 and 18089 on my node's firewall. I will add it at the beginning of my tutorial. Take into consideration that I have used 18089 but the default for the RPC commands is 18080. Anyway, thanks for the comment and the reminder.

Great job with this tutorial apogio.

Is important to mention that you can run bitcoin and monero on the same raspberry pi because the nodes run on a different port, some altcoins uses the same port than bitcoin and that can give use some problems but we can modify those ports in the config file and that should fix the problem.

And for those who want to test this tutorial but don't have a R.Pi then feel free to try in your PC. you can download the source for any os here:

Hosting a Monero node on the same machine

As I have mentioned in various places in this forum, I am a huge fun of Monero. So, without further delay, let's run a monero node on our Raspberry Pi.

Configuring Firewall to allow incoming connections on ports 18080 & 18089

I am using ufw for this tutorial. So the command should be:


Downloading & Installing Monero binaries

We will download the binaries in our Downloads folder and we will install them.


Now, all the binaries are install in our /usr/local/bin directory.

Let's check if they work using the command


It should print an output that displays the available options for monerod binary.

Configuring Monero node

We are almost ready to roll, but we need to create the configuration file for our node. We will create it in our external SSD, in the path /media/apogio/BTC/monero.


Now let's paste the following data inside the file:


The last 2 lines will be removed after the initial blockchain synchronization.

Let's start our node by running the following:


Now monero runs on the background, downloading the blockchain. We can easily check the status by running:


It will return something like the following example:


That's it, we are now running a monero node.

Connecting Monero GUI wallet to our node

The final step is to connect a wallet to our node. Of course we could use the monero-wallet-cli binary, but for our tutorial we will connect the Monero GUI wallet to our node.

After downloading the appropriate version for our OS, we will need to choose the "Advanced mode".



Create a new wallet:



Then head over to the node settings and simply add the IP where the node is hosted and the port.
