What it is (simple definition)
Merged mining (Auxiliary Proof of Work / AuxPoW) allows you to mine:
-
a parent chain (the main PoW chain you’re actually mining), and
-
an auxiliary chain (a second PoW chain that “accepts” the parent’s work as valid)
…in the same mining process.
How it works (high level)
-
You mine the parent chain normally.
-
At the same time, your miner includes a commitment proving it also worked on the auxiliary chain’s block template.
-
If your PoW meets the auxiliary chain’s difficulty, you can submit it there too.
-
If your PoW is strong enough for the parent chain, you may get both rewards (parent + auxiliary). If not, you may still get only the auxiliary reward (depending on difficulty and setup).
So, the key idea is: one hash attempt can potentially “count” for both chains.
Why people use merged mining
-
Extra revenue without proportional extra cost: You may earn the auxiliary coin on top of your normal mining rewards.
-
Better security for the smaller chain: The auxiliary chain “borrows” the hashpower of the parent chain, making it harder to attack.
-
Efficient use of hardware: Especially useful when the auxiliary chain alone wouldn’t attract enough miners to be secure.
Common example
-
Bitcoin (parent) + Name coin (auxiliary) is the classic example of merged mining.
Is it good for beginners?
It can be, but mostly if you join a mining pool that already supports merged mining—because:
-
solo merged mining configuration can be technical,
-
pools often handle the AuxPoW details automatically.
Quick caveats
-
Not all coins support it. The auxiliary chain must be designed to accept AuxPoW.
-
Centralization risk: If only a few pools dominate merged mining, the auxiliary chain can become dependent on them.
-
Operational complexity: More moving parts, more places for misconfiguration.
