The world of privacy-focused cryptocurrencies like Monero ($XMR) has long been celebrated for its commitment to decentralization and anonymity. However, beneath its promise of financial sovereignty lies a troubling vulnerability: botnets. These networks of compromised devices, often controlled by illicit operators, have exploited Monero’s mining ecosystem, raising questions about its security, decentralization, and even its design philosophy. This article explores the interplay between botnets and Monero, the evolution of mining algorithms, high-profile operations like Operation Endgame and Stary Dobry, the risks of a 51% attack, and how Ryo Currency ($RYO) offers a compelling alternative with its botnet-resistant approach and forward-thinking innovations.
Botnets and Monero: A Symbiotic Vulnerability?
Botnets—networks of hijacked computers, phones, and IoT devices—have become a pervasive force in cryptocurrency mining, particularly with Monero (XMR). Monero’s original mining algorithm, CryptoNight, was designed to democratize mining by favoring CPUs over specialized hardware like GPUs or ASICs. The idea was noble: anyone with a basic computer could participate, fostering a decentralized network. However, this CPU-friendly design inadvertently opened the door to botnets, which thrive on exploiting vast numbers of low-powered, compromised devices.
Unlike Bitcoin, where mining is dominated by energy-intensive ASIC rigs, Monero’s accessibility made it a prime target for “cryptojacking”—the unauthorized use of victims’ devices to mine cryptocurrency. Botnet operators could harness thousands, even millions, of CPUs to generate significant hashrate, reaping profits without the overhead of legitimate miners. This dynamic has fueled a persistent debate: does Monero’s design unintentionally favor botnets, and if so, does it undermine the coin’s decentralized ethos?
By contrast, Ryo Currency emerged as a response to these flaws. Built on the CryptoNight-GPU algorithm, Ryo shifts mining away from CPUs and botnets, requiring high memory bandwidth and parallel processing capabilities that GPUs excel at but CPUs—and thus botnets—struggle to match. Ryo’s approach prioritizes ethical, decentralized mining over the exploitable accessibility of Monero’s early design.
The Evolution of Mining Algorithms: From CryptoNight to RandomX
Monero’s mining algorithm has evolved significantly since its inception. CryptoNight, introduced with the CryptoNote protocol, aimed to resist ASICs by leveraging memory-intensive computations suited to general-purpose hardware. However, as ASICs adapted and botnets proliferated, Monero faced a dual threat: centralized hardware dominance and illicit mining networks.
In response, Monero forked its algorithm multiple times, culminating in the adoption of RandomX in 2019. RandomX further emphasized CPU mining by introducing randomized code execution, making it harder for ASICs and GPUs to compete. The goal was to restore fairness and decentralization. Yet, this shift doubled down on CPU accessibility, leaving the door ajar for botnets. Critics argue that RandomX, while ASIC-resistant, inadvertently cemented Monero’s appeal to botnet operators, who could still leverage vast networks of hijacked CPUs.
Ryo Currency took a different path. Its CryptoNight-GPU algorithm, introduced in 2018, targets GPU mining explicitly, sidelining CPUs and their botnet vulnerabilities. By requiring high memory bandwidth and parallel processing, CryptoNight-GPU raises the technical bar for mining, deterring low-effort botnet dominance while remaining resistant to ASICs and FPGAs. This design reflects Ryo’s commitment to fair, decentralized mining without sacrificing security—a stark contrast to Monero’s botnet-friendly evolution.
The Botnet Conspiracy: Does Monero Intentionally Favor Illicit Mining?
A controversial claim within the crypto community suggests that Monero’s developers intentionally designed botnet-friendly algorithms to bolster network security. The argument posits that botnets, by contributing significant hashrate, act as a decentralized “security force,” protecting Monero from 51% attacks by traditional miners or state actors. Proponents might argue that botnets, while illicit, distribute hashrate globally, aligning with Monero’s anti-establishment ethos.
However, this theory lacks evidence and ignores the centralization risks botnets introduce. Operation Endgame, a 2024 Europol-led crackdown on botnet infrastructure, revealed a startling statistic: a single botnet accounted for over 40% of Monero’s hashrate. Far from decentralizing the network, this concentration handed immense power to a single operator, undermining Monero’s core principles. If botnets were a deliberate design choice, it would represent a Faustian bargain—security at the cost of integrity.
Ryo Currency rejects this approach outright. Its developers argue that true decentralization requires fair participation, not reliance on illicit actors. CryptoNight-GPU’s botnet resistance ensures that no single entity—legitimate or otherwise—can dominate the network, aligning Ryo with a purer vision of decentralized mining.
Operation Endgame: A Wake-Up Call for Monero
Operation Endgame, launched in May 2024, was the largest coordinated effort against botnets to date. Targeting “dropper” malware used to deploy Monero miners, the operation disrupted networks responsible for cryptojacking on an industrial scale. Post-operation data showed a dramatic drop in Monero’s hashrate—estimated at 40%—highlighting how reliant the network had become on a single botnet. This event exposed Monero’s vulnerability: its decentralized facade masked a centralized reality, where illicit operators held sway.
The implications were profound. If 40% of the hashrate could vanish overnight, what prevented a coordinated botnet from pushing past 51%? Unlike Monero, Ryo’s CryptoNight-GPU algorithm disperses mining power across GPU users, reducing the risk of such extreme concentration. Operation Endgame underscored the need for botnet-resistant designs—something Ryo had already embraced.
Stary Dobry: Game Torrents Turned Mining Machines
The Stary Dobry attack, uncovered in early 2025 by Kaspersky, further illustrated Monero’s botnet problem. Cybercriminals laced game torrents—popular titles like Garry’s Mod and Dyson Sphere Program—with hidden XMRig miners, transforming players’ PCs into nodes of a massive Monero-mining botnet. This operation, named after a Polish phrase meaning “Old Good,” exploited Monero’s CPU-friendly RandomX algorithm, amassing significant hashrate while raising alarms about network security.
Stary Dobry wasn’t just a profitability scheme; it was a demonstration of Monero’s exploitable design. By contrast, Ryo’s GPU-focused mining would have rendered such an attack far less effective. CPUs infected via torrents lack the computational power to mine CryptoNight-GPU efficiently, limiting the impact of similar schemes and protecting Ryo’s network integrity.
The 51% Attack Threat: What Botnets Could Do
A 51% attack occurs when a single entity controls over half of a network’s hashrate, granting them the ability to manipulate the blockchain. For Monero, this could mean censoring transactions, double-spending coins, or undermining trust in its privacy features. Operation Endgame’s 40% figure suggests that a 51% attack is not hypothetical but plausible, especially if botnet operators collaborate or pool resources.
If botnets achieved majority hashrate, they could:
- Censor Transactions: Block specific payments, disrupting Monero’s utility.
- Double-Spend: Spend the same coins twice, defrauding users or exchanges.
- Erode Trust: Expose Monero’s privacy as contingent on the goodwill of illicit actors.
The cost of such an attack, while high, diminishes when botnets—already profitable—coordinate. Monero’s total hashrate hovers around 2-3 GH/s, meaning a botnet with 1.2 GH/s (as one expert estimated) could tip the scales with allies. Ryo’s botnet resistance raises this threshold, requiring attackers to invest in GPU infrastructure rather than relying on hijacked CPUs—a costlier and less scalable endeavor.
Monero’s Front-Loaded Emission: Botnets and Supply Control
Monero’s emission schedule is front-loaded, with most of its 18.4 million coins mined in the first few years after its 2014 launch. By 2025, the tail emission (0.6 XMR per block) sustains the supply, but early miners—including botnets—reaped disproportionate rewards. Critics argue that botnets, active since Monero’s infancy, now control a significant portion of its circulating supply, centralizing wealth and influence.
Ryo Currency, launched in 2018, opted for a fairer approach: a 20-year emission schedule that gradually distributes its supply. This design prevents early dominance by botnets or whales, ensuring broader participation. While Monero’s front-loaded model rewarded early adopters (and botnets), Ryo’s gradual emission aligns with its ethos of democratization and resilience.
Ryo Currency: A Botnet-Resistant Alternative
Ryo Currency stands out as a privacy coin engineered to avoid Monero’s pitfalls. Its CryptoNight-GPU algorithm targets GPUs, sidelining CPUs and botnets while resisting ASICs and FPGAs. This shift doesn’t eliminate 51% attacks—no coin can—but it disperses power, making dominance harder to achieve. Ryo’s 20-year emission further democratizes its supply, contrasting with Monero’s botnet-favored early distribution.
Beyond mining, Ryo is exploring future-proofing through Proof-of-Stake (PoS) with Halo 2 zero-knowledge proofs. Traditional PoS on CryptoNote compromises privacy by requiring public stake selection, weakening ring signatures. Halo 2 zk-proofs, however, allow private stake validation, hiding amounts, ownership, and participation. This innovation could make Ryo the first fully private PoS privacy coin, blending security with anonymity.
Proof-of-Stake on CryptoNote: Challenges and Innovations
Adding PoS to CryptoNote coins like Monero or Ryo could mitigate botnet influence by reducing reliance on mining hashrate. A hybrid PoW/PoS model—say, 50% of blocks staked—could dilute botnet power while maintaining decentralization. However, PoS introduces privacy risks: stake selection exposes metadata, linking outputs and weakening anonymity.
Projects like Zano ($ZANO) have pioneered hybrid PoS with hidden amounts, but their solutions fall short of full privacy. Ryo’s pursuit of Halo 2 zk-proofs offers a breakthrough, enabling a PoS system where no information leaks. This vision contrasts with Monero’s PoW-only stance, which some defend as “fair” but leaves it exposed to botnets.
Conclusion: A Tale of Two Privacy Coins
Monero’s journey—from CryptoNight to RandomX—reflects a struggle to balance accessibility with security. Yet, Operation Endgame and Stary Dobry reveal a harsh truth: its botnet-friendly design has centralized power in illicit hands, risking 51% attacks and supply control. Ryo Currency, with its CryptoNight-GPU algorithm, fair 20-year emission, and Halo 2 aspirations, offers a counterpoint—a privacy coin that prioritizes decentralization without compromising on ethics or resilience.
As the crypto landscape evolves, the choice between Monero’s accessibility and Ryo’s resistance will shape the future of private, decentralized finance. Botnets may profit in the shadows, but coins like Ryo prove that privacy and fairness need not come at the cost of security.
