SASEUL myth check, part 1

SASEUL mines on one home graphics card

What people say

“There are no coins left you can mine on a home computer”

Going by a 28-day record on one graphics card

That's wrong

  • Ethereum mining ended in 2022
  • Bitcoin is mined with special mining machines
  • SASEUL is mined on one graphics card by joining a group that mines together
The group behind the record is small, though, so coins don't come in evenly.

Yes. SASEUL can be mined with one NVIDIA graphics card in a home computer. The coin you mine on SASEUL is called SL (the short name of the SASEUL coin).

You don't mine alone. You join a mining pool (a group that mines together and splits the coins). There's also a 28-day record from one graphics card a few years old, on home internet.

What is proof of work (PoW)?

Proof of work (PoW) is a system where whoever does lots of calculating and finds the answer first gets the coins. Getting coins this way is called mining. It's like scratch cards: the more you scratch, the better your odds of a win.

Lots of calculating means the computer has to work. That uses electricity.

So "can you mine at home?" really asks whether a home computer can do this calculating. Coins that dropped proof of work can't be mined at all. Coins where special machines compete are hard for a home computer to join.

Why do people say there are no coins left to mine at home?

I'd guess it's mostly because of what happened with two well-known coins.

Ethereum ended proof of work on September 15, 2022, so there's been no mining since. This switch is called "The Merge." It's explained on ethereum.org's page on The Merge.

Bitcoin is mined with machines built only for mining (specialized hardware), says the official Bitcoin site's FAQ (frequently asked questions). In other words, it's not a coin you mine on an ordinary home computer.

These two things seem to be why the saying "there's nothing left to mine at home" spread. But these aren't the only proof-of-work coins. SASEUL is mined with proof of work too.

Did people once say individuals couldn't mine SASEUL either?

Yes. In early 2024, someone on a Korean online forum for miners asked about mining SASEUL.

Another post said it was unclear how to mine, and unclear whether anything was left after paying for the electricity.

Why was it like that back then?

This is my guess. A 2023 article in Jeongbo Tongsin Sinmun (a Korean IT and telecom newspaper) described SASEUL mining as something you took part in by installing a node (a computer holding a copy of the record book). It said you could install a node on a home PC, and setup took about 30 minutes.

A node can use a lot of the internet connection. That may be why the home internet dropped back then. But that method wasn't checked directly, so this isn't certain.

How is it mined now?

It works differently now. You run a mining program on an NVIDIA graphics card and connect it to a pool. The mining program only sends its calculating results to the pool.

Here's the setup behind the 28-day record. There was no separate dedicated line.

What Setup behind the record
Graphics card One NVIDIA graphics card a few years old
Computer An ordinary Windows 10 PC
Internet Regular home internet
Period August 18 to September 15, 28 days

The roughly 860 MH/s in this record (the numbers on the screen below are blurred) is the hashrate (calculating speed). It means more than 800 million guesses a second.

The mining program screen on this card, about 4 days in (September 15). Calculating speed (hashrate) about 860 MH/s. The exact numbers are blurred.

This record was made with the graphics card set to half use (50% usage). At lower usage, the mining program lets go of the card often. So you can still use the same computer for the internet or documents while it mines.

Can you now tell how to mine, and whether anything's left after electricity?

Yes, you can now tell how to mine. You need two graphics card programs from NVIDIA, the mining program, and an address to receive coins (like a bank account number). Setting it up takes six steps.

People also said it was unclear whether anything was left after electricity. Here's the electricity used and the coins received, from the 28-day record.

What 28-day record
Extra electricity from mining 55 W (watts). Over a month that's 39.6 kWh (the unit on your electric bill)
SL received per day, 28-day average 24 (including the days when settings were still being changed)
SL received per day, average over the 13 days fixed at half use (50%) 39 (including three days with none)
Electricity cost per SL 12 to 20 KRW (Korean won): 12 KRW at 39 a day, 20 KRW at 24 a day. At the most expensive step of Korea's household electricity tiers (step 3), electricity only

How much electricity it takes to mine one SL is covered in detail in the one-month record. To work it out for your own bill, multiply 39.6 kWh by your price per kWh.

Are there downsides to mining at home?

Yes. You can mine at home, but it isn't all good for an individual.

How much power does the whole SASEUL network have?

The hashrate of everyone mining SASEUL right now adds up to about 6.88 TH/s. That's the number shown on the front page of the pool site (saseulmine.com) on September 27, 2026. The same day, the statistics screen (Statistics) of the official block explorer shows 6.26 TH/s. That's the same value, just written in units of 1,024 multiplied four times (about 1.1 trillion) instead of 1 trillion.

MH/s means 1 million guesses a second, and TH/s means 1 trillion guesses a second. 1 TH/s is 1 million MH/s. Divide 6.88 TH/s by this one card (about 860 MH/s), and it's the power of about 8,000 cards of this class put together.

What did the check find?

The saying: "There are no coins left you can mine on a home computer."

What checks out now: Ethereum mining is over, and Bitcoin is mined with special machines. SASEUL can be mined by joining a pool, with one graphics card in a home PC and home internet. But the pool behind the record is small, so coins don't come in evenly.
