Title: How secure is it to set up a bitcoin node? Post by: Reynaldo on January 03, 2015, 05:41:55 PM As a node i mean just installing bitcoind on a raspberry pi and letting it run 24/7
Are there any implications that i have to be aware of? I have not found anything about the security related to the nodes, information is appreciated.

Post by: shorena on January 03, 2015, 06:18:31 PM As a node i mean just installing bitcoind on a raspberry pi and letting it run 24/7 You will need >32GB for the blockchain data. Are there any implications that i have to be aware of? I have not found anything about the security related to the nodes, information is appreciated. Dont use it as a wallet and you are fine.

Post by: Reynaldo on January 03, 2015, 06:28:21 PM One more question, I've set it up and i have the space, 5tb will do.. is there any way to limit the bitcoind download/upload speeds?

Haha obviously.. thanks :) Does anyone know how to limit upload/download speed? should i just get a program that does it per process?

Haha obviously.. thanks :) Does anyone know how to limit upload/download speed? should i just get a program that does it per process? 1. Install "wondershaper" sudo apt-get -y install wondershaper 2. Setup Up and Downloadlimits like this: sudo wondershaper eth0 512 512 Thanks i've found dummynet and nethogs for monitoring.. its awesome, I'll also try wondershaper. edit: seems like dummynet is far more complex too and its better used to simulate network traffic, wondershaper will do in conjuction with nethogs.

Post by: Kipsy89 on January 03, 2015, 09:02:14 PM Is a RaspberryPi capable of running a full node, actually? I though you needed a ton of memory to run a node effectively! How much memory do they have? I don't believe running a crappy node helps the network much, but rather cripples it even if the intent is good!

The memory usage for Bitcoin Core doesn't necessarily be that much. https://bitcointalk.org/index.php?topic=765934.msg8632982#msg8632982 The heavy I/O load could be a problem for your SD card though.

I've been monitoring it (downloading the database right now), and it does not go above 200 MB and I'm only allowing 10 connections till it finishes downloading the whole blockchain I also use USBS for swap, my configuration file for fstab looks like this: Code:
