Cryptocurrency Mining on a Raspberry Pi (it's fun....trust me)

A Raspberry Pi can mine Monero (XMR) using CPU-based proof-of-work, and the setup is straightforward enough to get accepted mining shares—though it’s almost certainly not profitable once electricity costs are counted. The payoff is educational and practical: it teaches how blockchain transactions get bundled into blocks, why mining is competitive, and how Monero’s design makes it feasible for small hardware rather than locking the race to specialized machines.

Mining starts with the blockchain’s basic promise: transactions are recorded publicly and can’t be easily altered. When someone sends cryptocurrency, the transaction is broadcast to the network, verified by nodes, and placed into a waiting area often called a memory pool. Miners then compete to package transactions into the next block by solving a cryptographic hash puzzle. The first miner to solve the puzzle gets the right to add the block and earns a block reward. In Bitcoin-style systems, the puzzle difficulty rises as more miners join, and rewards go to whoever finds the solution fastest—so small computers struggle against large-scale competitors.

That’s why the project avoids Bitcoin and Ethereum. Those networks are dominated by high-throughput hardware such as GPUs and ASICs (application-specific integrated circuits). The transcript cites Antminer as an example of purpose-built Bitcoin mining equipment, with costs far beyond a Raspberry Pi. With so much compute concentrated in data centers, a credit-card-sized computer would rarely, if ever, win blocks.

Monero is chosen instead because its mining algorithm is designed to resist ASIC advantage. The transcript contrasts Bitcoin’s SHA-256 approach with Monero’s RandomX algorithm and describes “ASIC prevention” as a core feature intended to keep mining more decentralized. The goal is that ordinary devices—including a Raspberry Pi—can still contribute meaningfully to the network, even if they won’t get rich.

The practical build begins with installing a 64-bit Raspberry Pi OS image onto an SD card, then using headless setup to enable SSH and configure Wi‑Fi. After booting, the process updates packages, installs build dependencies, and compiles XMrig (the mining software) from source. Next comes wallet creation: a Monero wallet is set up (the transcript uses GUI wallet / “Gooey Wallet” as an example), and the wallet address is copied for mining payouts.

To actually earn Monero, the Pi joins a mining pool—demonstrated with Gulf / MoneroOcean (gulf dot minero ocean.stream, port 10128). Pools matter because even Monero mining on a single Raspberry Pi is too unlikely to win blocks on its own. The transcript shows how XMrig reports hash rate (speed), accepted shares, rejected shares, and connection details including RandomX and difficulty. Multiple Raspberry Pis can be run simultaneously against the same pool, and the pool’s website can display worker performance and estimated owed amounts.

Finally, the economics land where expected: profitability is unlikely. The transcript notes that electricity costs can outweigh mining returns, citing mining calculators that suggest roughly a penny per day loss. Still, the project is framed as worthwhile for fun, hands-on learning, and the chance to accumulate a small amount of XMR—especially if Monero’s price moves over time (with a reminder that this isn’t financial advice).
