MINING / THE MECHANISM
One stream of work. Separate chains.
Auxiliary proof of work lets compatible networks verify the same mining effort.
Picture a pool assembling several sealed envelopes. Each contains an auxiliary chain’s proposed block. The pool commits to those blocks inside the parent candidate, then sends the mining job to Scrypt hardware. The hardware keeps searching; it does not divide into a separate machine for every coin.
When a result meets an auxiliary network’s target, the pool submits that block with an AuxPoW proof. Dogecoin Core checks the commitment and its connection to the parent header. A result need not become an accepted Litecoin block to qualify for an auxiliary chain; each network applies its own target and consensus rules.
Dogecoin enabled AuxPoW through its 1.8 release in 2014. The relationship shares compatible work, not balances, monetary policies or governance. Litecoin does not become a Dogecoin validator, and neither chain inherits Bitcoin’s SHA-256 security. More participating work can strengthen an auxiliary network’s resistance to attack, but only work actually committed to that network counts. Pool concentration, software correctness and independent validation still matter.
- Hashing algorithm compatibility is necessary; auxiliary consensus support and pool integration are also required.
- Merged mining reuses work. Profit switching changes the primary coin being mined.
