ALERT: Dogecoin co-founder Billy Markus just called the proposed shutdown of merged mining "absolutely idiotic."
"This would be the most idiotic thing we've ever done. The fact that anyone would consider ending merged mining is a direct violation of the security model that made Dogecoin survive the last decade. Some people need to sit down and look at the hash rate numbers before they destroy a network that’s been running for 12 years without a single security incident."
Liquidation pending if they push this through. Don’t ignore the signal.

Context: The Invisible Safety Net That Traders Don’t See
Dogecoin doesn’t mine alone. Since 2014, it has shared its Scrypt hash rate with Litecoin through merged mining. Miners solving Litecoin blocks can simultaneously produce valid Dogecoin blocks—zero extra electricity, zero extra hardware. This arrangement means Dogecoin borrows security from Litecoin’s massive miner base.
In 2023, over 85% of Dogecoin’s hash rate came from Litecoin miners running merged mining clients. Take that away, and Dogecoin’s network security collapses by an order of magnitude. Attack cost for a 51% assault drops from millions of dollars to a few hundred thousand.
This isn’t hypothetical. We’ve seen the playbook unfold with Bitcoin Cash after its split from Bitcoin: hash rate fragmentation, repeated chain reorganizations, and eventual marginalization.
Core: The Hash Rate Math No One Wants to Say Out Loud
Let’s put the numbers on the table.
Current Dogecoin hash rate: ~1.2 PH/s. Litecoin hash rate: ~950 TH/s. The overlap isn’t 1:1 because some miners choose to mine Dogecoin natively, but the vast majority run merged mining stacks.
If merged mining ends, here’s what happens:
- Litecoin miners instantly stop producing Dogecoin blocks. They have zero incentive to waste CPU cycles on a chain with no payout.
- Native Dogecoin miners stay, but they’re a fraction—around 0.15 PH/s based on pre-merged mining era data. That’s an 87.5% drop in hash rate.
- Block time stretches. Dogecoin’s target is 1 minute, but with drastically fewer miners, block intervals can balloon to 5–10 minutes. Confirmation times become unreliable.
- 51% attack cost plummets. At the current hash rate, renting enough Scrypt hash to double-spend Dogecoin for an hour costs roughly $12,000 on NiceHash. After termination? You can do it for under $2,000.
This isn’t just a theoretical risk—it’s a mechanical certainty.
I know this because I spent the 2020 DeFi Summer building Python scripts to monitor MakerDAO liquidation thresholds. The same principles apply here: when you remove a safety net, the system becomes fragile. The only difference is Dogecoin’s safety net is merged mining; MakerDAO’s was stability fees. Both are invisible to the average holder until they fail.

Contrarian: The Unreported Battle—Security Independence vs. Stagnation
The standard narrative is that ending merged mining is a security risk pushed by naive maximalists who want Dogecoin to "stand on its own." That’s half true. But the deeper story is about who benefits from the status quo—and who loses.
From my 12 years covering this space, I’ve learned that every "upgrade" proposal has a hidden constituency. In Dogecoin’s case, the push to end merged mining is likely coming from two groups:
- Second-layer protocol developers who want Dogecoin to support smart contracts. They argue that depending on Litecoin for security makes Dogecoin a "subordinate chain," which hurts developer interest. They see independent mining as a prerequisite for innovation.
- Newer retail holders who don’t understand the technical dependency. They hear "merged mining" and think "controlled by Litecoin" without realizing the alternative is a chain with less than 100 TH/s.
But here’s what the contrarian angle misses: Litecoin itself may be considering ending merged mining.
Litecoin’s mining rewards are halving in 2027. If Litecoin’s block subsidy drops, merged mining becomes less attractive for Dogecoin miners too. The arrangement is symbiotic, but if one side starts questioning it, the other should prepare for a divorce.
No one is talking about this second-order effect. The entire debate frames Dogecoin as the potential divorcée, but Litecoin’s incentives are shifting too. Litecoin developers have quietly discussed whether merged mining tilts hash rate away from Litecoin-only transactions during high DOGE fee events. There’s a cost asymmetry: when Dogecoin’s transaction fees spike, Litecoin miners temporarily prioritize DOGE blocks, sidelining LTC blocks. Litecoin’s ecosystem loses confirmation speed.
This is the blind spot. The co-founder’s warning isn’t just about Dogecoin’s security—it’s about an existential negotiation between two chains that were never designed to share a life this long.
Based on my experience auditing Layer-1 consensus papers during the 2017 ICO boom, I can tell you: when a network’s security depends on another chain’s continued goodwill, you have a structural vulnerability that no amount of community sentiment can fix. The real question isn’t "should we end merged mining?" It’s "how do we build Dogecoin’s own hash rate before the divorce happens?"
Takeaway: The Clock Is Ticking—Here’s What to Watch
The co-founder’s statement buys time, but it doesn’t solve the underlying dependency. The Dogecoin ecosystem must start diversifying its mining base before the next Litecoin halving.
Three signals to track:
- Dogecoin Core GitHub: Look for any PRs proposing changes to merged mining logic. That’s your early warning.
- Litecoin Foundation communications: If they publish a post calling merged mining "suboptimal," the divorce papers are being drafted.
- Scrypt ASIC manufacturer orders: A sudden increase in orders for new Scrypt miners could indicate someone is preparing to build native Dogecoin hash—or it could be Litecoin’s next-gen hardware. Either way, it’s a liquidity signal.
Arbitrage window closing in 10 minutes.
The market hasn’t priced in this migration risk. Dogecoin’s implied volatility is still low because traders think it’s a meme coin with no technical decisions to make. That’s wrong. Every long-term holder should ask themselves: Am I betting on Billy Markus winning this debate, or on a structural solution being found?
I know which side my position is on.
