20 reasons why Raspberry Pi is not a good option to Run a Bitcoin & Lightning Network Node
While the Raspberry Pi is a highly versatile and popular device among hobbyists and enthusiasts due to its affordability, using it as a full Bitcoin node is generally not considered the best option. Here are the reasons why:
1. Limited processing power: Raspberry Pi devices are equipped with processors that are relatively low-powered compared to those in desktop or server-grade machines. A full Bitcoin node demands substantial computational resources, which the Raspberry Pi might struggle to provide efficiently, especially considering the continuous growth of the Bitcoin blockchain.
2. Insufficient RAM: Typically, Raspberry Pi models come with a limited amount of RAM, which may result in performance challenges when running resource-heavy applications such as a full Bitcoin node. Given that the Bitcoin blockchain’s size is continuously growing and a full node needs to store the entire blockchain in memory, the limited RAM on a Raspberry Pi might lead to slower synchronization and potential performance issues.
3. Storage limitations: The ever-growing Bitcoin blockchain currently extends beyond hundreds of gigabytes in size. Raspberry Pi devices, which commonly use SD cards for storage, may not offer sufficient capacity for this. Furthermore, the SD cards may not provide the robustness and durability required for continuous operation as a full Bitcoin node.
4. Network bandwidth: Participating in the peer-to-peer Bitcoin network as a full node involves receiving and relaying transactions and blocks to other nodes. The limited network bandwidth capabilities of Raspberry Pi devices can potentially lead to slower synchronization and potential connectivity issues, especially in high-traffic networks.
5. Security concerns: The Raspberry Pi is not designed with security-critical applications, like running a Bitcoin full node, in mind. It may therefore be vulnerable to attacks and exploits, potentially compromising the security of the Bitcoin network.
6. Limited upgradeability: Unlike a traditional desktop or server system, Raspberry Pi lacks a direct upgrade path for its hardware components. This limitation means that as the Bitcoin network grows and evolves, the device may quickly become outdated, potentially requiring the purchase of a new unit to keep up with increasing demands.
7. Software compatibility: Not all Bitcoin-related software or updates may be compatible with the operating system or the ARM architecture of the Raspberry Pi. This may limit the ability of users to utilize newer features or maintain the necessary security updates.
8. Heat dissipation: The Raspberry Pi, especially when under high computational load, can generate substantial heat. Continuous operation, such as running a Bitcoin node, could lead to overheating, reducing the lifetime of the device or even causing sudden shutdowns.
9. Energy efficiency: While Raspberry Pis are generally energy-efficient for small tasks, they are not designed for high-load, continuous computing like running a Bitcoin node. In such a scenario, their energy efficiency can decrease significantly, making them less optimal compared to specialized hardware designed for such tasks.
10. Technical support: Compared to other, more traditional systems, the Raspberry Pi community may not provide the same level of technical support for complex operations like running a Bitcoin node. While there is a lot of general support for Raspberry Pi, niche uses such as this might not have extensive troubleshooting resources.
11. Durability: Raspberry Pi devices are not built to withstand continuous heavy load operations such as running a Bitcoin node. The wear and tear caused by such a task can decrease the device’s lifespan considerably.
12. Unstable power supply: Raspberry Pi is usually powered via a micro-USB port, which can be an unstable source of power. Any disruptions or instabilities in the power supply could lead to data loss or corruption, especially in tasks like running a Bitcoin node which require continuous, stable power.
13. Lack of redundancy: In professional server settings, redundancy is often built-in to prevent data loss and maintain high availability. Raspberry Pi lacks such features. If the device fails, or if data becomes corrupted, it could lead to significant downtime or even loss of the entire blockchain data stored on the device.
14. Non-optimization for multithreading: Many Bitcoin client implementations, like Bitcoin Core, are designed to use multiple cores simultaneously for faster processing. However, the Raspberry Pi’s processor is not optimized for such multithreaded tasks which can hinder performance.
15. Networking issues: Raspberry Pis often use Wi-Fi for network connectivity, which can be less stable and slower than wired connections. A drop in connection or reduced bandwidth can affect the performance of the Bitcoin node, slow down transaction verification, and lead to a poor overall performance.
16. Dependency on external storage devices: Due to limited on-board storage capacity, a Raspberry Pi requires an external SSD or hard drive to store the full Bitcoin blockchain. This dependency on external storage devices can introduce additional points of failure, including data corruption and drive failures.
17. Performance issues with USB-connected SSDs: Running a Bitcoin node from an external SSD connected via USB can lead to performance issues. The USB interface, particularly if it is USB 2.0, is significantly slower than a direct SATA or PCIe connection, leading to slower read/write speeds. This can severely hamper the performance of your Bitcoin node.
18. Power consumption of external drives: External drives, especially HDDs, can require substantial power, more than what the Raspberry Pi can supply through its USB ports. This can lead to instability, potential data loss, or even hardware damage if the drive draws too much power.
19. Limited USB ports: A Raspberry Pi has a limited number of USB ports. If an external SSD takes up one port, you may quickly run out of available ports for other peripherals. Using a USB hub can introduce additional potential points of failure.
20. Data integrity: The Raspberry Pi file system, especially when running on an SD card or an external SSD over USB, may face higher risks of data corruption in case of power loss or hardware failure. This could be disastrous for a Bitcoin node, where data integrity is of utmost importance.
Considering all these factors, it becomes clear that a Raspberry Pi might not be the best choice for running a full Bitcoin node in the long term. However, that doesn’t make the Raspberry Pi useless in the Bitcoin realm. It can still contribute to Bitcoin-related projects, like running lightweight wallets or other network contributions, based on the specific project requirements and the device’s capabilities.
If you are looking for a more powerful and secure option for running a full Bitcoin node, you may want to consider using a dedicated computer or server instead.
Conclusion:
Even if you could find one under $100 or even $200 dollars. Availability seems to be September 2023 or onward even if they upped the productions to 1 Million units a month! Clown world!
It is not sable enough over the long therm plus limited bandwidth due the USB constraints even with a NVMe USPA enclosures, like for example: SABRENT M.2 SSD Enclosure, USB C 3.2 Gen 2 to NVMe SSD.
Search Google yourself also why to run a Bitcoin node for the long term with Raspberry Pi is not optimal, but this is what I found:
Running a Bitcoin node with a Raspberry Pi for the long term might not be a good idea due to several reasons:
- Storage Constraints: One of the biggest hurdles is storage space. Most Raspberry Pi users run the OS on a microSD card which doubles as internal storage. Unless you have a large microSD card, you’ll need to increase your storage. The entire Bitcoin blockchain requires more than 350GB of storage1.
- Insufficient Hardware: The experience of running a Lightning node on Raspberry Pi, especially on older models like the 3, has been described as “horrible”. It is suggested to use Raspberry Pi 4 or a used mini desktop instead of a Raspberry Pi 3 due to better performance and cost-effectiveness2.
- Limited Resources: If you compile bitcoin-core and LND/CLN from source, you can run a node on a Raspberry Pi. But as soon as you add any web interface or use a node manager like Umbrel, you will quickly run out of RAM. The Raspberry Pi can also draw more amps than the power supply can give, causing stability issues that can corrupt data. These are serious considerations for running Lightning nodes as these issues could potentially result in loss of funds2.
- Power and Connectivity Issues: The Raspberry Pi is prone to issues around power and slow USB HDD connection. These issues can cause data corruption and instability in the node, making it unsuitable for long-term and serious use2.
Overall, while it’s an interesting concept and possible to run a node on a Raspberry Pi, it may not be the best choice for long-term and serious usage due to the reasons outlined above. A more powerful and robust system such as a desktop or laptop would provide a better experience.
