GPU mining is mostly over. ASICs have taken most of what's left. But CPU mining is quietly having a moment — not because the returns are spectacular, but because a specific category of coin was deliberately designed to keep it alive.
These coins share a philosophy: mining should be accessible to regular hardware, resistant to industrial farms, and distributed across individuals rather than concentrated in warehouses. The algorithms are purpose-built to make CPUs competitive. And in 2026, several of these networks are healthier than they've ever been.
Here are five worth your attention, and the thread that connects all of them.
1. Monero (XMR) — RandomX
Monero is the coin that legitimized CPU-friendly mining as a design decision rather than an accident.
RandomX launched in late 2019 and was specifically engineered to favor general-purpose CPUs. The algorithm makes heavy use of random code execution and relies on the full memory bandwidth and branch prediction capabilities of a modern processor — things that are expensive to replicate efficiently in custom silicon. ASICs exist, technically, but they don't maintain the margin over CPUs that they do with SHA-256 or Ethash, which keeps the playing field significantly more level.
Monero is the standard against which every other CPU coin is measured. It has real liquidity, real privacy properties (ring signatures, stealth addresses, confidential transactions), and a development community that takes the ASIC-resistance mandate seriously enough to hard fork when necessary.
Mining profile: High memory requirement (~2GB per thread). Best on machines with many cores and fast RAM. A modern desktop CPU mines competitively. Expected returns are modest relative to difficulty, but liquidity is real.
Why it matters in 2026: Regulatory pressure on privacy coins has increased, but so has demand from people who actually need financial privacy. Monero's fundamentals are stronger for being pressure-tested.
2. Verus (VRSC) — VerusHash 2.2
Verus takes the CPU-first philosophy further than almost anyone else, and adds a layer of ambition that makes it one of the more interesting projects in the space.
VerusHash 2.2 is specifically tuned to be fastest on modern CPUs with AES hardware acceleration — nearly every CPU made in the last decade qualifies. On FPGAs and GPUs the algorithm deliberately underperforms relative to expectations, and ASIC development has never produced a meaningful efficiency advantage. The result is that Verus is genuinely mined by individuals on regular hardware, at scale.
Beyond mining, Verus is building a multi-chain, decentralized finance system with native bridge capabilities, ID infrastructure, and a currency definition system that's legitimately novel. Whether that roadmap pays off is an open question, but the mining layer is real and the community is technically serious.
Mining profile: Excellent performance-per-watt on modern Intel and AMD CPUs. Works well on lower-power machines. Can be merged-mined with Verus sister chains.
Why it matters in 2026: One of the few CPU coins with a development story beyond "maintain the chain." If the DeFi layer gains traction, the mining foundation matters more.
3. KOTO (KOTO) — yescryptR8G
KOTO is a Japanese privacy coin, a Zcash fork running yescryptR8G, maintained by a developer known as wo01. It has been running continuously since 2018, has never had an ASIC problem, and has a small but genuinely dedicated community mostly in Japan.
I've written about KOTO in detail elsewhere on this blog, so I'll keep this brief: it's the coin I find most personally interesting, and the one I mine most actively. The network is small — around 60,000 hashes per second total at current difficulty — which means an individual miner with a few machines can hold a meaningful share of hashrate.
yescryptR8G is memory-hard and specifically tuned to be hostile to GPU mining. The GPU exodus of 2019 wasn't an accident — it was the algorithm working as designed. What's left is a network of CPU miners, many of them running the same hardware they use for everyday computing.
Mining profile: Low barrier to entry. Runs well on Raspberry Pi 5, Intel NUCs, home servers. Pool options are thin (there are two serious Western-facing pools; I run one of them at koto.isekai-pool.com).
Why it matters in 2026: Niche, but genuine. If you want to understand what a CPU-first privacy coin looks like in practice, KOTO is the clearest example running today.
4. Zephyr Protocol (ZEPH) — RandomX variant
Zephyr is a newer entrant worth watching — a privacy coin built on the Monero codebase with an added algorithmic stablecoin layer called ZEPHUSD.
The mining algorithm is RandomX-derived, meaning it inherits Monero's CPU-friendly design. What differentiates Zephyr is the attempt to solve a long-standing problem with privacy coins: volatility makes them difficult to use as actual payment instruments. If KOTO or Monero drops 40% in a week, spending them on goods or services becomes psychologically fraught. Zephyr's reserve-backed stable asset is designed to give the network a medium of exchange that doesn't swing wildly.
Whether the economic model holds under stress is unproven. The project is young. But the mining layer is real and the concept is sound.
Mining profile: Same hardware profile as Monero. Any machine that mines XMR mines ZEPH competitively.
Why it matters in 2026: If it works, Zephyr solves the spending problem at the protocol level. That's directly relevant to what GameGlass is trying to do at the application level.
5. Salvium (SAL) — RandomX variant
Another Monero fork, Salvium adds compliance features — specifically, the ability to audit transactions for regulatory purposes while maintaining default privacy. This is a deliberate attempt to make a privacy coin acceptable to businesses and exchanges that can't touch fully opaque networks.
The mining layer is standard RandomX. The differentiation is entirely at the protocol and compliance level.
Mining profile: Same as Monero and Zephyr. CPU-competitive, GPU-resistant by design.
Why it matters in 2026: If exchange listings and merchant adoption require some auditability, Salvium is betting that "privacy with an opt-in transparency key" is the regulatory sweet spot. An interesting experiment.
What All Five Have in Common
These coins are not random survivors. They share a deliberate design philosophy:
1. Algorithm hostility to industrial mining. Every coin on this list chose or developed an algorithm specifically to prevent ASIC dominance. That choice has economic and ideological consequences — it keeps the network distributed, but it also keeps the hashrate lower and the returns more modest than industrial coins.
2. Privacy as a feature, not an afterthought. All five treat financial privacy as a legitimate use case. Whether that's Monero's ring signatures, KOTO's shielded transactions, or Zephyr's selective disclosure, the default assumption is that transaction data belongs to the parties involved.
3. Small networks, real communities. None of these are top-100 coins by market cap. All of them have active development, genuine communities, and chains that have been running for years. They're not abandoned experiments.
4. Nowhere obvious to spend the coins. This is the problem all five share, and it's the problem that sits at the center of why GameGlass exists.
Mining any of these coins produces something real — genuine proof-of-work, genuine computation, genuine energy expenditure. But the economic loop doesn't close. You mine, you accumulate, and then you wait for liquidity that may never come, or you sell at thin spreads on obscure exchanges.
The missing piece isn't a better algorithm or a better pool. It's a spending layer — somewhere to use coins on things you actually want, without going through a full exchange-to-fiat cycle.
That's what we're building. If you mine any of these coins and you've hit the "now what" moment, the waitlist is open.
