Raspberry Pi 2 Bitcoin Node

Not long ago I set up a Bitcoin node on a Debian Wheezy VPS to teach myself about Bitcoin and the blockchain in general. It was a great learning experience but the memory requirements of the Bitcoin software kept causing my VPS instance to run out of memory so the kernel would constantly be killing off the bitcoind process. A growing blockchain also meant the node was getting close to the limit of its available disk space as well. Simply increasing the amount of disk space available to the VPS instance with the plans offered by the hosting provider was going to be prohibitive for the purpose so I decided to assess other solutions. Luckily I had a spare Raspberry Pi 2 that I had yet to do anything with at home. So I made the decision to try and install a Bitcoin node on that instead to save some money. The main expense with using the Raspberry Pi was going to be finding enough storage for the block chain. I didn’t have an SD card that was big enough at home to¬†accommodate the operating system image and the block chain. So I opted to buy a cheap external USB flash drive to keep it separate from the root filesystem. After formatting with ext4 the flash drive has 57Gb of available space, at the time of writing the blockchain takes up 40Gb of space so that leaves a further 17Gb for future growth.

Running a Bitcoin Node on Debian Wheezy

Over the last few years I have keenly followed the rise of Bitcoin from its early days trading at around $8USD. I watched with interest when it made its sharp rise to $1200USD and then felt a bit of dismay with more recent decline back to around the $200USD mark. As a whole I think Bitcoin and the Blockchain are both game changing technologies that are yet to see their full potential. So over the last few months rather than just watching the Bitcoin exchange rate bounce around the place. I sought to get a deeper understanding of how the underlying technology works and how it can be extended further. As part of this learning process I decided to set up a Bitcoin node both to act as learning resource for myself and to help contribute something to the larger Bitcoin network. In this article I am going to run through the process of turning a VPS running Debian Wheezy into a fully fledged Bitcoin node. Continue reading “Running a Bitcoin Node on Debian Wheezy” »
