What Is “Merged Mining” and How Is It Related to AuxPoW?
Merged mining is the process that enables Auxiliary Proof-of-Work (AuxPoW). It allows a miner to use the same computational work (hash power) to mine two different blockchains simultaneously.
The miner includes the block header of the secondary chain (the one using AuxPoW) within the block of the primary chain. If the hash meets the difficulty target for both chains, the miner receives block rewards from both.
Merged mining is the technical mechanism that allows the smaller chain to "merge" its security with the larger chain.
