Merge Mining

Merge Mining is a technology that allows the same computational work to be used simultaneously for mining multiple compatible blockchains. As a result, a miner can receive rewards from multiple networks without performing a completely separate amount of computation for each one.

How Merge Mining Works

One network typically acts as the primary chain, while an auxiliary network uses proof of completed work to verify that a computational task has already been solved. If the solution meets the requirements of the auxiliary blockchain, it may also be accepted by that network.

Thus, the auxiliary blockchain can use computational work that has already been performed as part of the primary network. This allows a smaller network to increase its security without having to independently attract a comparable amount of computational resources.

Economic Meaning

For miners, the main advantage of Merge Mining is the ability to receive additional rewards without a proportional increase in computational workload. Additional profitability depends on the specific rules of the networks and the value of the assets received.

However, Merge Mining requires technical compatibility between the blockchains. Not every PoW network can use this technology, and the mechanism for verifying the proof of work must be provided for by the protocol.

Relationship with Proof-of-Work

Merge Mining is particularly associated with blockchains that use a compatible Proof-of-Work mechanism. Its purpose is not to change the mining principle itself, but to reuse computational work that has already been performed in another compatible network.
