Just make sure that with any option you choose, you have over 350GB of available space. You could also use a high capacity micro SD card or a high capacity thumb drive. But because running a full node involves downloading the entire Bitcoin blockchain, which is a few hundred gigabytes (and growing), we're going to add an external hard drive to the setup. So generally Raspberry Pi users will run the operating system on a small-ish micro SD card. One thing you might notice is that the Raspberry Pi doesn't ship with storage. A machine running a full node can also be used for other tasks, but because a full node should be connected to the network at least six hours a day (and ideally continuously), it makes sense to use an inexpensive computer dedicated to the task. The Raspberry Pi is small, inexpensive, and meets the minimum requirements for running a Bitcoin full node. In this guide, we're going to learn how to run a full node using a Raspberry Pi 4 and an external hard drive. In order for the Bitcoin network to operate securely, it requires many additional full nodes to ensure the miners are following the consensus rules and help relay transactions to other nodes in the network.Īnd since there is no direct financial incentive to run a full node (unlike mining), it requires good Bitcoin citizens to step up and help out. And while mining can be lucrative, it also requires an upfront investment and uses a considerable amount of energy. When a miner (or mining pool) is the first to publish a new block, it receives a mining reward. If a miner tries to publish a block that doesn't follow the rules, it will simply be ignored. Other nodes, simply called full nodes, verify the transactions and ensure that miners are following the consensus rules. Some nodes, called miners, record new transactions by publishing them in "blocks". In order for the Bitcoin network to operate securely, it requires many additional full nodes to ensure the miners are following the consensus rules.
