I guess someone could obtain the list of node IPs (trivial), there would be a slim chance those machines could contain bitcoins for stealing.
People who know what they are doing keep them offline however, so the risk is then gone.
So its the same risk whether I keep a node running 24/7 or 6/5. I dont see the point honestly. Besides that, the IP alone is not really helping. The actual node could be behind any number of network devices (e.g. a NAT router) youd have to attack first in order to get to the machine with the keys. Unless of course bitcoin core itself would be vulnerable to an attack. A SPV client is also easily detected by a malicous node and you know they have coins otherwise it makes next to no sense to run one. Thus IMHO a SPV client is actually a more logical target, considering that the obstacles to reach the coins are basically the same. Again, assuming that the client itself is not vulnerable to a direct attack. I also thought we are talking about full nodes on dedicated machines (or VPS) here. I would not expect that a single one of those to have a wallet with any funds. I know I have disabled the wallet on my node. Well as I said, the chances are slim. |

I'm considering grabbing a Raspberry pi 2 and hook up one on my old HDD's in order to run a Bitcoin node here at home  |

I gave up with the Raspberry Pi node. It kept running out memory and swapping out.
It will be interesting when pruning is released. The master branch has MIN_BLOCKS_TO_KEEP set to 288. That gives a maximum of 288MB of disk space to store the blocks (with full blocks). The MIN_DISK_SPACE_FOR_BLOCK_FILES is set to 550MB, so it will normally store more info (and blocks won't be 1MB each). It still needs to store the UTXO set too. According to Statoshi, it is 650MB, and rising linearly. |

I never bothered waiting for the pi to sync.. Currently run a full node on an old laptop, that pulls from master each evening. I disabled wallet support when configuring, it lowers the required memory somewhat.

Also the Pi took hours to compile the bitcoin core from source. More swapping out.

A full node processes and relays transactions, improving connectivity, stability, and safety of the network. There are also incentive programs that pay you to run one (due to this benefit). In addition, a full node is usable as an entry point to the network. If you want to run a Bitcoin service then having a full node allows you to see and process transactions. |

It gives the world bitcoin. No nodes, no bitcoin. |

So is a Full node basically just running Bitcoin-QT?

Yes, there are other full node implementations though. Like btcd. |

All day everyday and open port 8333, otherwise it's not a full node. |

All day everyday and open port 8333, otherwise it's not a full node. Running it 5 minutes a day and only allowing outbound connections its still called a full node, as long as it can sync in that time. A full node is any network node that is capable of enforcing all the network rules. |

A full node is any network node that is capable of enforcing all the network rules. Maybe by definition, I run my bitcoin core about once a day to sync up and have a full copy of the blockchain, but I only run it for maybe 30 minutes. I wouldn't consider myself running a full node. |

No, I do not have a bitcoin full node. I think the requirements to run one are quite high. Do you need a dedicated server for it?

Moderate VPSs can handle one, just not some huge one with thousands of connections. |

Moderate VPSs can handle one, just not some huge one with thousands of connections. I run mine off a VPS with 2 GB ram and a single core. It handles 50 connetions fine. The only "propblem" will be the disk space soon. I might be able to switch from SSD to HDD though as I dont need the extra speed anway. |

i don't have any node running but want to setup one if anyone can point me to simple and easy to follow tutorial for this. I just pre-ordered a bitseed (V2) and will run it from my home connection. I think it makes sense to run a full node on a simple and dedicated hardware designed specifically for this purpose. |

There are also incentive programs that pay you to run one (due to this benefit). Thanks for the hint! Found the Bitnodes project ( topic about it in this forum). Are there any others? Edit: Bitnodes is only for static IP nodes, since registration is IP address bound. So it's nothing for me, since I have dynamic IP address change. |
