How Monero Mining Works: RandomX and Proof of Work Explained

Monero mining is how new XMR is created and how the network is kept secure. It uses a proof-of-work algorithm called RandomX, which is built to run on the ordinary CPUs in everyday computers and to resist the specialized ASIC machines that dominate Bitcoin mining. That design keeps mining open to regular people, not just large operators.

About every two minutes, one miner wins the right to add the next block of transactions and takes the full reward of newly issued XMR. There is no cut for a company or a foundation. Because RandomX favors general-purpose hardware, the competition is spread across many small miners instead of a handful of industrial farms.

Those design choices are what make Monero mining unusual, so they are worth walking through one at a time.

What mining actually does on Monero

Mining does two jobs at once on Monero. It issues new coins, because a mined block is the only way fresh XMR enters circulation, and it secures the network, because the computing work miners perform is what makes the ledger expensive to attack. Both jobs are paid for by the same block reward.

Proof of work is the mechanism underneath. Miners race to solve a hard computational puzzle, and the first to find a valid answer gets to add the next block and claim its reward. That answer is easy for everyone else to verify but costly to produce, which is what makes rewriting past blocks impractical. An attacker would have to redo all of that work faster than the rest of the network combined. If the general idea of proof of work is new to you, the primer on proof of work covers it, since this guide focuses on the Monero-specific part. On Monero, a new block arrives roughly every two minutes, and the whole reward goes to the miner who found it, with none skimmed for developers (source: Monero project, About). Because a block confirms about every two minutes, payments settle faster than on networks with longer block times, though most wallets still wait for several confirmations before treating a payment as final. So mining is both the mint and the security guard, funded by one reward.

RandomX, the algorithm built for ordinary computers

RandomX is the proof-of-work algorithm Monero uses, and it is deliberately designed to run best on ordinary computer processors. Instead of one simple calculation repeated over and over, it runs random programs and leans heavily on memory. Those are things a general-purpose CPU does naturally, and a narrow, specialized chip does poorly.

Monero contributors built RandomX, and the network adopted it from release 0.15 (source: Moneropedia, RandomX). The core idea is in the name. Rather than repeating one fixed operation, RandomX generates and executes random sequences of instructions, and it uses memory-heavy techniques that a CPU handles well because it already has fast, flexible access to large amounts of memory (source: RandomX design repository). A chip built to do only one thing very fast, an ASIC, gains little advantage here, because there is no single fixed thing to optimize for. The memory requirement is the key defense. An ASIC earns its edge by stripping a chip down to one calculation, but RandomX forces every miner to use a large, fast pool of memory, and adding that much memory to a custom chip erases most of the cost advantage it would otherwise have. The practical result is that a normal desktop or laptop is close to as efficient, for the money, as anything a specialist could build. That is the whole point, and it leads straight into the next question.

Why Monero resists ASICs, and why that matters

Monero resists ASICs on purpose, because ASIC mining tends to concentrate a network in the hands of whoever can afford the most specialized hardware. By keeping mining CPU-friendly, Monero spreads both issuance and security across many ordinary participants, which supports a more decentralized and more fairly distributed coin.

This is the clearest difference between Monero mining and Bitcoin mining. Bitcoin uses an algorithm that ASICs can run far more efficiently than any general computer, so its mining has consolidated into large industrial operations sited near cheap electricity. Monero took the opposite path. It has even changed its algorithm in the past specifically to break any ASICs that appeared, treating ASIC-resistance as an ongoing commitment rather than a one-time feature. This is why the network schedules regular upgrades and has been willing to change its proof of work more than once: keeping ASICs out is treated as ongoing maintenance, not a battle that is ever finally won. The table shows the contrast.

Why does the difference matter? A coin mined by a few big farms concentrates both the new supply and the practical power to influence the network, while a coin anyone can mine on a laptop keeps both spread out. For the other side of the comparison, the overview of how Bitcoin mining works explains the ASIC model in depth. Monero's choice is a values choice as much as a technical one.

Solo mining vs pool mining

You can mine Monero on your own or as part of a pool, and the difference is about variance rather than the coin itself. Mining solo, you keep a whole block reward, but you might wait a very long time to find one. In a pool, you combine effort with other miners and share smaller, steadier payouts.

Mining is a lottery in the short run. Solo, a small miner might go months without winning a block and then win a full reward all at once, which is exciting but unpredictable. A mining pool combines the work of many miners so the group finds blocks more often, then splits each reward in proportion to how much work each member contributed. The result is frequent, smaller payouts instead of the solo lottery (source: Monero project, mining). Most small Monero miners use a pool for that reason. Pools differ in how they share rewards. Some pay a fixed amount for each unit of accepted work, while others pay out only when the pool finds a block and then split it by recent contribution, which shifts a little more of the timing risk onto the miner. For a beginner, those differences matter less than picking a reputable, appropriately sized pool. There is a tradeoff, though. Large pools concentrate influence over the network, which cuts against the decentralization that ASIC-resistance is meant to protect, so miners are often encouraged to join smaller pools. If you have mined Bitcoin at home, the home mining parallels carry over, and the actual step-by-step for Monero lives in how to mine Monero rather than here.

This is also why the Monero project points miners toward solo mining or P2Pool, a peer-to-peer pool that pays out steadily without handing any single operator a large slice of the network's power. The rule of thumb is simple: a pool smooths your income, but the network's health depends on that computing power staying spread out, so the convenient choice and the socially useful choice are not always the same. For most people starting out, the honest path is to join a mid-sized or peer-to-peer pool, watch its share of the total network, and treat the first weeks as learning rather than earning.

What miners earn: the block reward and tail emission

A Monero miner earns the block reward, which is newly issued XMR plus the fees from the transactions in that block. After the main issuance ended in 2022, the reward settled at a permanent 0.6 XMR per block, or slightly less on oversized blocks, so mining keeps earning a steady reward indefinitely rather than trailing off to nothing.

The reward is what pays for security, so how it is designed matters. During Monero's early years the reward shrank block by block, but it did not fall to zero. Instead it flattened at a permanent tail emission of 0.6 XMR per block, which continues forever and keeps miners paid long after most coins are already issued (source: Moneropedia, tail emission). That is deliberate. A network whose block reward disappears has to fund its security on transaction fees alone, which Monero's designers judged too risky. The reward itself has two parts. The larger part is the newly issued XMR from the tail emission, and the smaller part is the fees paid by the users whose transactions the block includes. As the network matures, fees are meant to grow into a more meaningful share of what miners earn, but the tail emission guarantees a baseline either way.

There is a security logic to that baseline. Miners keep pointing hardware at a network only while it is worth their while, so a reward that never disappears means the chain never has to hope that fees alone will keep enough honest miners online. In that sense the tail emission is less about issuing new coins and more about paying, permanently, for the work that keeps old transactions expensive to rewrite.

The full monetary-policy picture, including how that tail keeps inflation low, is in the guide to XMR supply and tail emission. Whether the reward is actually profitable is a separate question of costs, and the parallel guide to Bitcoin mining profitability frames the same math. For a miner, the takeaway is that the reward is modest but permanent, and it goes entirely to whoever did the work.

The honest downside: Monero and cryptojacking

The same design that lets anyone mine Monero on a normal computer has a dark side. Because it mines efficiently on ordinary CPUs, Monero is a favorite of malware that secretly mines on other people's machines without permission, a practice called cryptojacking. It is a misuse by attackers, not a flaw an honest miner needs to fear.

It is worth being clear about this. Monero's CPU-friendliness, which is what makes its mining fair and open, is exactly what makes it attractive to malware, because a hijacked laptop or server can mine it usefully where it could not mine an ASIC coin. As a result, Monero has been a common payload for cryptojacking software (source: Wikipedia, Monero). Two things are worth separating here. First, this is attackers abusing other people's computers, not a risk to someone who chooses to mine Monero on hardware they own. Second, it says nothing about whether Monero itself is sound. It is a side effect of a neutral, egalitarian design, in the same way that cash's usefulness to criminals says nothing about whether cash should exist. For anyone learning about Monero, the useful takeaway is to recognize cryptojacking for what it is, keep your own machines patched and monitored so they are not conscripted, and judge the coin on its design rather than on how criminals abuse it.

From BloFin's vantage as an exchange operator, a coin whose issuance is spread across many small CPU miners tends to distribute its newly issued coins more widely than one minted by a few industrial farms, which is part of what people mean when they call Monero's distribution fair. That is a structural observation about how the coin enters the world, not a claim about its price or a product we offer. For the bigger picture of the asset, the hub guide on what Monero is ties mining back to the coin.

Frequently asked questions

Can I really mine Monero on a normal computer?

Yes. That is the defining feature of Monero mining. Because RandomX is built to run on ordinary processors, a regular desktop or laptop can mine XMR, unlike coins such as Bitcoin that effectively require purpose-built ASIC hardware. You will not out-earn a room full of machines, and any single computer earns only a trickle, but the barrier to starting is low. It is one of the few coins where you can genuinely mine with hardware you already own, which is exactly what the ASIC-resistant design is meant to allow.

Do I need a GPU or an ASIC to mine Monero?

No ASIC, and you do not strictly need a GPU. RandomX is optimized for CPUs, so a modern multi-core processor is the natural tool, and Monero is deliberately built so that specialized ASIC hardware gains little advantage. GPUs can mine it too, but the design does not reward them the way some other coins do. The short version is that the processor you already have is the intended hardware, which keeps the barrier to entry low and the miner base wide.

What is a mining pool, and do I need one?

A mining pool is a group of miners who combine their computing power, win blocks more often as a group, and split each reward in proportion to the work each contributed. You do not strictly need one, but most small miners use a pool because it turns rare, unpredictable solo payouts into smaller, steadier ones. The tradeoff is that very large pools concentrate influence over the network, so choosing a smaller pool is often encouraged to keep mining decentralized, which is the whole point of Monero's approach.

Is mining Monero worth it?

That depends entirely on your electricity cost, your hardware, and Monero's price at the time, none of which this guide predicts. Because you mine on ordinary hardware, the upside per machine is modest, and in many places the electricity can cost more than the coins earned. Treat home mining first as a way to learn how the network works and to support it, and only second as a possible source of income, after you have checked the current numbers for your own situation rather than trusting a generic calculator.

Does mining Monero damage my computer?

Mining runs your processor at full load for long stretches, which produces heat and uses electricity, so sustained mining does add wear and cost over time. It will not instantly break a healthy computer, but poor cooling and constant maximum load shorten hardware life, and the power bill is a real expense. If you mine, keep the machine well-ventilated, watch its temperatures, and treat the electricity as part of the true cost. Casual, occasional mining is low-risk; running an old laptop flat out around the clock is harder on it.

What is RandomX, in one sentence?

RandomX is the CPU-friendly, ASIC-resistant proof-of-work algorithm that Monero uses to keep mining open to ordinary computers and spread across many participants. It works by running random programs and using large amounts of memory, which favors general-purpose processors over the narrow specialized chips that dominate mining on other coins. In short, it is the piece that makes Monero mining egalitarian by design.

How is Monero mining different from Bitcoin mining?

The core difference is the hardware the algorithm rewards. Bitcoin's SHA-256 is best run on specialized ASICs, so its mining has concentrated into large industrial farms, while Monero's RandomX is best run on ordinary CPUs, so its mining stays spread across many small participants. Practically, that means you can start mining Monero with a computer you already own, whereas competitive Bitcoin mining needs dedicated machines. Monero prioritizes decentralized, egalitarian mining; Bitcoin prioritizes maximum raw hashpower.
