Namecoin (NMC) merge mining pool

Namecoin is merge-mined with Bitcoin: mine BTC on BCMonster and earn NMC on the same hashrate, at no extra power cost.

How to earn Namecoin

Mine Bitcoin on any BCMonster BTC port (3333 Standard, 3334 Pro, 3337 Elite — or the solo ports).
Get a Namecoin address (for example from Namecoin Core).
Add it as your NMC payout address in your wallet profile on bcmonster.com.

# Mine BTC — Namecoin and Fractal Bitcoin come along for free
URL: stratum+tcp://bcmonster.com:3333
User: YOUR_BTC_ADDRESS.workername
Pass: x (pool) — or m=solo (solo)

Nothing changes on your miner. Without an NMC address on your profile, merge-mined NMC can't be paid to you, so add it once.

About Namecoin

Namecoin (2011) was the first fork of Bitcoin and the first coin to use merge mining (AuxPoW): the same SHA-256 work that tries for a Bitcoin block also counts toward Namecoin blocks. That lets Bitcoin miners secure Namecoin without spending any extra electricity.

Why BCMonster

Solo or pool on every port. Password x = pool (PPLNS), m=solo = solo (you keep the whole block). Or use the dedicated solo port.
Flat 1.5% fee, pool and solo. Payouts are checked every 2 minutes.
AsicBoost (version rolling) on every port, Stratum V2 on every Standard, Pro and Elite port, and BCMonster Rapid Tune difficulty that settles in minutes.
No account or sign-up needed — your wallet address is your login. Live stats on your own worker page.

Common questions

How do I merge mine Namecoin?

Mine Bitcoin on BCMonster and add a Namecoin payout address in your wallet profile. NMC is merge-mined automatically on all BTC ports with no miner changes.

Does merge mining Namecoin reduce my Bitcoin earnings?

No. Merge mining reuses the same proof of work, so your BTC mining is unchanged and NMC is extra.
