LITECOIN + DOGECOIN · SCRYPT

Merged-mining Litecoin + Dogecoin on ARM

1 · Should you mine this on a CPU?

Honestly: not for money. Scrypt is ASIC-dominated — on a pool, a CPU earns fractions of a cent. Two things still make it interesting. First, merged mining: one scrypt work unit pays both LTC and DOGE at once — how that works is the good part of this page. Second, the solo-lottery angle: Bitcoin has a whole cottage industry of low-power lottery gadgets, but scrypt has essentially none — no ESP32-class toys, and the small USB scrypt sticks are long discontinued. An old phone at ~25 kH/s on a few watts is one of the only silent, always-on ways to hold a merged LTC+DOGE lottery ticket. For actual CPU revenue, mine Verus or Monero instead.

2 · How merged mining works

Dogecoin accepts Litecoin proof-of-work via AuxPoW: the same scrypt share can satisfy both chains at once. This is handled entirely pool-side — the miner just mines scrypt; the pool credits you LTC and DOGE for the same work. Nothing to configure in the miner.

Two pool styles exist. Account-based (e.g. litecoinpool.org): you register, log in as username.worker, and set payout addresses for both coins on the website — both are credited automatically. Address-based pools skip registration: your LTC address is the login, and DOGE payout (if offered) is configured via the password field or the pool's site.

3 · Get wallets

You'll want two addresses: Litecoin (Litecoin Core, or Electrum-LTC) and Dogecoin (Dogecoin Core, or MultiDoge). With an account-based pool you paste both into your pool account settings once.

4 · Configure the miner

Worked example with litecoinpool.org (account-based; register first, set LTC + DOGE payout addresses on the site):

CLI

command 
$ ./primo -a scrypt -o stratum+tcp://litecoinpool.org:3333 \
      -u YOUR_USERNAME.worker1 -p x

config.json

config.json — run with ./primo -c config.json 
{
  "algo": "scrypt",
  "url":  "stratum+tcp://litecoinpool.org:3333",
  "user": "YOUR_USERNAME.worker1",
  "pass": "x"
}

APK

  1. Configuration → Algorithm → scrypt. Threads defaults to your core count.
  2. Primary pool: URL and litecoinpool username as above (username + .workername), password x.
  3. SAVE, then START MINING. Each algorithm keeps its own profile — switching back to Verus later restores that config untouched.

5 · What to expect

Hardware Hashrate
A76-class big core (1 thread)~4.8 kH/s
8 threads (phone or RK3588)~25 kH/s

For scale: a scrypt ASIC does ~1 GH/s — about 40,000× an 8-core phone. Hence "not for money".
