Why does the mining pool change its address every time it mines a block? Does anyone know where this code is?
I want to fix the mining receiving address of the mining pool or change the address after every 100 blocks mined.

what software are you referring to? dogcoind?

[slightlyskepticalpotat]

If you are mining with outside software, typically you have to specify a fixed coinbasetxn address so all the coins go to the same address.

getauxblock generates a new address each mined block
createauxblock <address> then submitauxblock <hash> <auxpow> will generate to desired address.

Depends what mining software is being used to how you/they generate the blocks.

[msy2008]

The address can be reused 100 times or 1000 times before it is changed to another address without the need for me to set it up separately.
The existing version of the code only uses the address once by default. . .
I want to know where the code is

I want to know where the code is

Called here in the getauxblock RPC call:

dogecoin/src/rpc/mining.cpp

Line 1167 in a6d1220

GetMainSignals().ScriptForMining(coinbaseScript);

Which, through boost signals, calls:

dogecoin/src/wallet/wallet.cpp

Lines 3464 to 3473 in a6d1220

	void CWallet::GetScriptForMining(std::shared_ptr<CReserveScript> &script)
	{
	std::shared_ptr<CReserveKey> rKey(new CReserveKey(this));
	CPubKey pubkey;
	if (!rKey->GetReservedKey(pubkey))
	return;
	script = rKey;
	script->reserveScript = CScript() << ToByteVector(pubkey) << OP_CHECKSIG;
	}

As @farsider350 noted, if you want to control the address, createauxblock is the recommended RPC call to use (many pools already use this instead of getauxblock). You can then, even if you use the built-in wallet, control exactly to which address the coinbase tx will pay out, i.e. by calling getnewaddress whenever you desire to switch addresses.

But not every mining pool will consciously use createauxblock
When the mining pool only uses getauxblock, the receiving address can be received 100 or 1000 times instead of 1 time. Which code modification can do this? Thanks

I wouldn't recommend that. Not reusing addresses is a security feature, as you don't want to repeat signatures outside of a single transaction, in case of signing also weaknesses. Changing the default behavior like that would force pools to be less secure, so that's not really an option.

Are you asking this for your own pool?

To be honest, I am developing DOGM...
