Bitcoin Core

Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Is it possible to specify the number of Tor connections on a listening Bitcoin Core full node?

A standard listening node gets a maximum of 125 connections, clearnet and Tor. Is it possible to reserve say 25 connections for Tor only?

Going to run a Bitcoin Core full node: R-Pi 4, 4GB w/ 2TB ext.

I bought a special heat-sink case with a fan.

Can anybody recommend a good website with step-by step instructions? If so, you will be appreciated.

[help] How can I seamlessly extend disk for bitcoin-core full node?

Hello,
I'm running a bitcoin-core full node and serve customers wallet service. I set the chain data disk size to 400GB when first setting the node up and the disk is almost full now.
I'd like to increase the disk size without halting or stopping wallet service. Can I get advice or tips for doing it?
I'm using a cloud service for running the node and it's highly likely to stop `bitcoind` process if I increase disk size on the cloud console. (I don't think `bitcoind` can write to disk while the cloud service working on the disk)
Any help would be appreciated. Thanks!

What advantage does a Pi4 full node with Electrum Server on the same LAN with a desktop running Electrum, have over a desktop running Bitcoin Core full node and wallet? (optionally if you plan on using a Ledge S as cold storage)

Bitcoin Core Full Node - Almost giving up

Hey all,
I installed Bitcoin Core on an external 1TB Hard Disk, downloaded the entire blockchain in less than 18 hours and got synced.
Everything nice and smooth but I can't open the infamous Port 8333, so I continuously have only 8 outbound active connections and still 0 inbound connections (I can't open Port 8333 because I don't know how to do it).
I searched on the web but really I can't figure out how to solve this issue, I couldn't find any comprehensible help. I'd love to run a full node and contribute with my means to the network. I think that everyone of us should run a full node even if it looks like tech savvy stuff. Though, I don't get why it has to be so complicated.
Any suggestions?
Would love to hear your experience.
Thanks

Ledger Nano X + Ledger Live iOS + watch-only bitcoin core full node?

I'm not a blockchain expert. Question is this: Is the combination of 1. using Ledger Nano X for cool storage, 2. using ledger live iOS app for making transactions, and 3. using a bitcoin core full node with master pubkey for reliable verification of transactions... is that a secure method of using and storing bitcoins that also supports the decentralization of the network?
Does that lack any essential functionality? Any major security risks?

Bitcoin core full node upload bandwidth usage

I've had my first bitcoin core full node running for 24hrs as of this morning and it's sent 25gb of data in that time, is that about right, higher or lower than normal?
Edit: what do I need to put in the config file to limit the upload data as that's way too much for me to keep it running 24/7, I'll get a letter from my isp warning about usage again. Despite being on an unlimited package I usually get a letter warning about fair use when I go over 750gb a month.

Is there any risk on running a Bitcoin Core full node?

I'm thinking of starting a full node on a raspberry pi I have and allow it to be a "public node". Is there any risk on doing this? Can I be hacked? Is a good deal to use VPN/TOR?

Bitcoin Core full-node technical question: how to customize port?

I want to open full-node to incoming connections, but I am unable to open 8333 because it is already taken on my VPN. There are however other ports available for me to use.
Question is, how would I go about changing the port that my Bitcoin Core client uses? A DuckDuckGo search hasn't yielding any clear answer on this subject, other than it is possible to change the port that the Core client uses in the CLI.

What’s a Bitcoin full node? The Bitcoin network is a collection of computers all over the world running the Bitcoin Core software that verifies transactions and blocks. It’s the distribution of these “nodes” (the term for a computer attached to the network) and the fact that anyone can set one up that makes Bitcoin “decentralized.” Bitcoin Core is programmed to decide which block chain contains valid transactions. The users of Bitcoin Core only accept transactions for that block chain, making it the Bitcoin block chain that everyone else wants to use. For the latest developments related to Bitcoin Core, be sure to visit the project’s official website. Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work — but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
