Re: The port should be 8333? (node)

1, 2, 3. Port 8333 is correct regardless of pruned or not. 8333 is the default port, but in some cases (such as multiple nodes on the same local network), you might want to change it.
4. A pruned node stores only block information relevant to your wallet.
5. A full node provides block and transaction data to other nodes. I don't know specifically how being a pruned node affects the amount of outgoing data, but I imagine it reduces the amount significantly because you don't store the entire block chain.

For bitnodes, did you enter your node's local IP address, 192,168.x.x or 10.x.x.x, or did you enter the address for your local network?

The port should be 8333? (node)

Hello.
I downloaded the entire blockchain (600 gigs) and completed it. I chose the node type pruned, because I had no free space on the hard drive. And I think I am a node now.

Screenshot of bitcoin core status:

https://i.postimg.cc/RFLck79S/Screenshot-2024-07-29-212747.png

I have some questions and please help me:

1- Should my port be on 8333? I don't know what my current port is. Given that I am now a pruned node, do I need to be on port 8333?

2- If I want to be a full node in the future, should I be on port 8333?

3- What is the difference between being on port 8333 and not being on port 8333?

4 - What is the difference between full node and pruned? Is full node good and does it help the network more? Is pruned worthless?

i visit https://bitnodes.io/#join-the-network and After clicking the check node option on the site, I received this error:
(My IP:8333 is unreachable)
I did everything mentioned in the links below:
https://bitcoin.org/en/full-node#network-configuration --- https://bitcoin.org/en/full-node#port-forwarding and
https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/create-an-inbound-port-rule.

I'm sorry it took so long.
thank you very much ❤️

Unfortunately, I get the same error (My IP: 8333 is unreachable).

If I use 8333, considering that others will also connect to me, won't my internet security such as accounts, social networks, wallet, etc. be compromised?

It won't. People can connect to you via port 8333 but Bitcoin Core should be the only program that is listening on that port. Bitcoin Core does not reveal any sensitive data to anyone else and thus you should not need to worry about that.

Opening a port is limited to what programs listening to that port deals with the data. In this case, Bitcoin Core will not reveal anything sensitive or identifiable to you to your peers. It is purely transmitting blocks, transactions, peer info, etc.

Thank you dear friend. You guided me a lot today. If I had a question, I would definitely ask. Thankful

And one more question.
Should my port be on 8333?
I don't know what my current port is.
Why maps like this site: https://bitnodes.io/nodes/live-map/
It doesn't show anything in my country?

After clicking the check node option on the site, I received this error:
(My IP: 8333 is unreachable)

What does this mean? I'm not node?

You are a node. Nodes can either connect to others or let others connect to you. Assuming that you're not portforwarding 8333, then Bitcoin Core cannot accept incoming connections and other nodes cannot connect to you. However, you can still connect to others.

This doesn't impact your usability or utility in any way, but it would definitely be better if others could connect to you.

What is meant by current number of transaction and memory usage in memory pool?

Memory pool contains the unconfirmed transactions that your node sees and have yet to be included in a block. The number of transactions is the number of transactions in the memory pool and the memory usage is how much memory is being used to store them in your mempool.

Thank you very much

You’re a node if you’re running Bitcoin Core, no matter if its synchronized or not. You can turn off your computer after shutting down Bitcoin Core properly and you won’t have to synchronize again. If you’re not running Bitcoin Core all the time, then it would synchronize to the latest block whenever you turn it on again.

It doesnt turn on automatically upon start up. For it to be functioning as a node, you’d have to keep it running.

Thank you very much

Am I a node now?

Donald6680

Hello.
I downloaded 600 gigs of bitcoin core. Now the situation is like this (I posted the photo and the link is this:
https://i.postimg.cc/Hk5VB8kc/Screenshot-2024-07-29-135904.png

Am I a node now?

Do I need other settings?

Given that I have pruned the node type, if I turn off the computer, do I need to download 600 again? Should the computer always be on because it was a node? What happens if, for example, I don't run the program for about 5 days? Does the program work automatically if there is an internet connection or do I have to enter the program so that the program is active and does its work?

thank you

When I activate the limit and it is set to 2 GB, it seems that 12 GB will be saved. Not 600. It is true?

If you set the prune limit to 2 GB, you keep 2 GB of data from the blockchain and the UTXO set which should be around 11 GB in size as of now.

Quote from: Donald6680 on Today at 11:34:31 PM

But still, I don't understand that I don't have 600 gigs of space, where is the downloaded 600 gigs saved! UPDATE: I realized. The blockchain will be downloaded and removed from the hard drive at the same time, and the amount of 12 gigs will remain.

Almost true. Just note that you keep 2 GB of data from the blocks, not more.

Quote from: Donald6680 on Today at 11:34:31 PM

And one more question. Does the pruned node do the same thing that full does? I want to know if what I am doing is valuable or not.

Even if you run a pruned node, you still validate transactions and blocks and help the network to more decentralized.
As I already said, the downside is that you will have to redownload the blockchain if you want to import a new wallet.

Thanks for the complete explanation. You did me a favor, my friend ❤️

I will enable prun. You said that the whole blockchain should be downloaded. But I don't have 600 gigs of space. Does that mean I can't even use pruned? Because I don't have 600 gigs of free space on my computer.

You will be able to download the blockchain and run your node.
As I already said, you don't keep the entire blockchain if you run a prune node. Therefore, you don't need to worry about the storage size if you are going to enable pruning. You download the new blocks and at the same time, old blocks are removed from your hard drive.

thank you. Do I have to have 600 gigs of space?! (I want pruned node)

If you don't enable pruning, you will have to keep the entire blockchain. The current size of blockchain is around 600 GB and it will grow over time.

Quote from: Donald6680 on Today at 11:01:40 PM

When I tick, do I can change 2 gigs? For example, 10 gigs?

Yes, you can change the prune limit.

Again, if you run a pruned node, you will have to redownload the blockchain whenever you want to import a new wallet.

If you check "limit blockchain storage to...", you will run a pruned node which means that you won't store the entire blockchain in your hard drive.
A pruned node keeps the latest blocks and removes the old blocks over time.

It may worth mentioning that you will still have to download the entire blockchain even if you run a pruned node.
Also note that in the case you run a pruned node, you will have to redownload the blockchain, whenever you want to import a new wallet.dat file and you need to reindex or rescan the blockchain.

Hello.
I want to become a node in bitcoin core and I want to download 600 gigs.
I just don't know what is meant by limiting and restore backups for 6 days.
please guide me.
