Will Monero change its mining algorithm again?

Monero could change its mining algorithm again, but you should not assume a replacement is coming on a fixed schedule. As of 2026, it uses RandomX, and another major change would depend on a strong technical reason, careful testing, and broad support—not simply how long RandomX has been around.

Why Monero has changed it before

A mining algorithm is the set of computing tasks your device performs to help secure the network and compete for rewards. Monero’s choice reflects a goal: keeping mining practical on ordinary computer processors, or CPUs, rather than letting specialized machines dominate.

Monero originally used CryptoNight and later adjusted it several times. Those changes aimed to resist ASICs—machines built to perform one particular mining task extremely efficiently.

On November 30, 2019, Monero replaced the CryptoNight variants with RandomX. Instead of repeatedly making small changes to frustrate specialized hardware, RandomX uses varied computing tasks designed to suit general-purpose CPUs.

That history shows Monero is willing to change. It does not mean frequent replacements are inevitable.

What could justify another change?

A major replacement would need to offer enough benefit to justify disruption and risk. Possible reasons include:

• Specialized hardware gaining a decisive advantage. If credible evidence showed that custom mining machines could substantially outperform ordinary CPUs, the community could consider a response.
• A serious weakness in RandomX. A flaw that made mining unexpectedly cheap for some participants, or threatened network security, could require changes.
• A clearly better design. A new approach might offer stronger resistance to specialized hardware without creating worse security, performance, or accessibility problems.

Not every improvement would require abandoning RandomX. Developers could fix an implementation bug or improve mining software while keeping the same basic algorithm.

Also, a rising mining difficulty is not proof that RandomX is failing. Difficulty—the measure of how hard it is to find a valid block—adjusts every block as mining activity changes.

How a change would actually happen

There is no single owner who can simply order every Monero user to switch. A proposal would typically face public technical discussion, research, implementation, testing, and security review.

A replacement would normally require a hard fork, meaning a network rule change that older software cannot fully follow. Developers, mining pools, miners, and other network participants would need to coordinate compatible software around an activation point.

You should distinguish between an idea, experimental code, and an agreed upgrade. A discussion about “the next mining algorithm” is not, by itself, an announcement that RandomX is being retired.

What this means for your browser mining

If you mine through your browser, a future change could require the website’s mining software and its mining pool—the service that combines miners’ work—to update. Your browser might download updated code automatically, but you should still check the service’s instructions.

Do not buy hardware based on claims that an unconfirmed algorithm will guarantee higher earnings. Browser performance, electricity costs, and network competition still matter. Check a live mining calculator for estimates, and treat guaranteed-return claims as warning signs.

An algorithm change would not automatically erase your existing XMR or require you to hand over your wallet’s secret recovery words.

The bottom line

Monero can change its mining algorithm again if there is a convincing reason. For you, the sensible approach is to follow verified upgrade announcements, keep your mining software current, and avoid treating speculation as a scheduled replacement for RandomX.
