A Public Company Wants 1.5% of Dogecoin's Hashrate

One number anchors this whole story: 43,200 GH/s. That is the total hashrate Shuttle Pharmaceutical Holdings, a Nasdaq-listed company (SHPH) that agreed on April 30, 2026 to merge with Dogecoin mining firm United Dogecoin, plans to bring online through a fleet of up to 3,000 ElphaPex DG1+ Scrypt mining rigs, each rated at 14.4 GH/s. The merger, backed by an $11 million private placement, turned a pharmaceutical company into what its own announcements call the largest publicly traded Dogecoin miner, and it is a real, current example of institutional capital moving into merged-mining Scrypt hardware rather than SHA-256 Bitcoin ASICs. The number is worth working through directly instead of taking the company's own framing at face value.

The Arithmetic, Laid Out

Dogecoin and Litecoin share the same Scrypt hashrate through AuxPoW merged mining: hardware pointed at Litecoin's network effectively secures Dogecoin at the same time, since Dogecoin's proof of work is auxiliary to Litecoin's. That means the right denominator for United Dogecoin's planned fleet is the combined Litecoin and Dogecoin Scrypt network hashrate, not Dogecoin's number in isolation.

Figure	Value
Planned fleet size	up to 3,000 ElphaPex DG1+ units
Hashrate per unit	14.4 GH/s
Total planned fleet hashrate	43,200 GH/s (3,000 x 14.4 GH/s)
Litecoin network hashrate (August 16, 2026)	approximately 2,750,000 GH/s (2.75 PH/s)
Fleet's share of network hashrate	approximately 1.57% (43,200 / 2,750,000)
Merger agreement signed	April 30, 2026
Concurrent PIPE financing	$11 million

That 1.57% comes out close to the 1.5% figure the company itself has cited, which is a useful sanity check: the math holds up against the company's own claim rather than contradicting it. It is also, by construction, a hashrate-share calculation, not a probability claim. A single entity controlling 1.5 to 1.6% of a merged-mining network's hashrate does not change the underlying arithmetic that decides whether any individual miner, industrial or hobbyist, finds a block. It only describes how much of the network's total mining power that one company would represent once the fleet is fully deployed and running, which the company's own reporting places on a rolling timeline of roughly 60 days from unit delivery, subject to installation and power hookups actually going to plan.

What This Looks Like Next to a Hobbyist's Own Odds

Put United Dogecoin's planned fleet next to a single home Scrypt miner to see the actual gap in scale. A Bitdeer Sealminer DL1, one of the more efficient Scrypt ASICs available to hobbyists in 2026, runs at roughly 25 GH/s. Against the same 2,750,000 GH/s Litecoin network figure, that gives a per-block probability of 25 / 2,750,000, or about 0.00091%. Inverting that, a miner running that single unit continuously would expect to find a block roughly once every 110,000 blocks (2,750,000 divided by 25). At Litecoin's roughly 150-second target block time, that works out to about 210,240 blocks a year, so 110,000 expected blocks between finds comes out to about 0.52 years, or roughly 191 days, of continuous solo mining for one expected win. That is the same formula every miner on the chain uses, industrial fleet or single home rig: hashrate divided by network hashrate, nothing about scale changes the underlying math, only how many attempts a given amount of hashrate buys per unit of time.

What a Public Company's Dogecoin Mining Hashrate Does and Does Not Change

A single company adding 1.5 to 1.6 percentage points of network hashrate does two things worth separating clearly. First, it very slightly raises the total network hashrate once deployed, which very slightly lowers everyone else's per-attempt probability, an effect any hobbyist can compute for their own hardware the same way the table above computes it for a Sealminer DL1, by dividing their own hashrate by the new, larger network total. Second, and more significantly for the long-term shape of merged mining, it is a data point in a broader pattern of publicly traded companies treating Scrypt merged mining as a legitimate capital allocation rather than a hobbyist curiosity, alongside the ETF-driven institutional interest that has touched Litecoin more broadly this year. Neither of those effects changes what non-custodial mining actually pays out, or improves anyone's odds relative to their own hashrate; they only describe how the denominator in that hashrate equation is likely to keep growing.

What To Actually Do With These Numbers

If you already run Scrypt hardware at home, the honest takeaway is not alarm. A fleet arriving over roughly 60 days changes the network hashrate total gradually, not overnight, and your own solo odds were already a function of your hashrate against a constantly shifting denominator before this merger existed. What is worth doing is recalculating your own expected wait using the same formula above with current network hashrate, rather than a number from months ago, since that denominator moves with every institutional deployment like this one. For anyone solo mining Dogecoin or Litecoin through a pool that pays the full merged-mining reward directly to your own address, the payout mechanics work the same regardless of whether the hashrate finding the block belongs to a single hobbyist board or a fleet financed by a public company; NexusPool's Litecoin and Dogecoin mining support runs on the same non-custodial, Stratum V1 and V2 same-port infrastructure either way, and checking that infrastructure's current state directly is possible through the pool's public changelog rather than taking any claim, including this one, on faith.

None of this is investment guidance about Shuttle Pharmaceuticals, SHPH stock, Dogecoin, or Litecoin, and nothing here claims that any pool, hardware choice, or company entering the market improves an individual miner's odds. Those odds are set entirely by hashrate divided by network difficulty, identical for every miner on the chain, institutional fleet or single ASIC on a desk. Trust nothing. Verify the current network hashrate yourself before trusting any wait-time estimate, including the one in this post.
