Merge mining is a technique that allows miners to mine two or more cryptocurrencies simultaneously without compromising performance and profitability. It is suitable for cryptocurrencies that employ the same consensus protocol and hash function – SHA-265 (Bitcoin) and Scrypt (Litecoin).

In this article, we will focus on merge-mining Litecoin (LTC) and Dogecoin (DOGE), which are two proof-of-work (PoW) blockchains powered by the Scrypt algorithm, issuing coins that can be mined together.

So, without further ado, let’s get started.

What Is Merged Mining And How Does It Work?

Merged Mining is a method of mining multiple PoW-based cryptocurrencies that share a hashing algorithm simultaneously using the same mining hardware. The process allows miners to earn significant mining rewards by contributing to the computing power of two or more blockchains at once.

The concept was first proposed by Bitcoin’s pseudonymous creator Satoshi Nakamoto in 2010 to allow miners to mine BTC on the Bitcoin network, which acts as the “parent chain”, alongside another cryptocurrency powered by an auxiliary blockchain, also called a “child chain”. The only condition to be met here is that the child blockchain should follow the same mining algorithm as the parent chain.

The technique behind merged mining is called Auxillary Proof-of-Work (AuxPoW) and it serves as a complementary mechanism to the traditional PoW-based blockchains. AuxPoW allows miners to secure multiple blockchains simultaneously, enhancing the security and efficiency of distributed ledger systems. This means miners can contribute their computational power to secure a primary blockchain while validating transactions on an auxiliary chain without investing in separate resources for each.

For example, when merge-mining on Bitcoin, miners can use the computational process from the Bitcoin network (which acts as the parent blockchain) to validate transactions on a child blockchain (eg. Namecoin, Rootstock). In exchange for their contributions, miners are rewarded with coins mined on both the parent and auxiliary chains, helping offset their operational costs.

This enables miners to maximize their profits by securing both blockchains, increasing mining efficiency. It also enhances the security and viability of the smaller chain, making them less vulnerable to exploits like 51% attacks.

Merged mining is highly beneficial for miners as it is cost-effective and allows them to mine more than one cryptocurrency without needing to invest in additional hardware or modify their existing setup. Overall, it creates a win-win situation for the miners involved by offering reduced costs and increased revenue opportunities.

Merged Mining On Litecoin

Just like Bitcoin, the Litecoin network is also compatible with merged mining. While the former supports auxiliary chains powered by the SHA-256 algorithm, merged mining on the latter involves mining LTC alongside other Scrypt-based cryptocurrencies like Dogecoin (DOGE).

The Dogecoin network adopted merged mining with Litecoin in August 2014, and since then the blockchain has grown substantially. Within a month of implementing the technique, Dogecoin’s hash rate increased by 1,500%. According to various sources, approximately 90% of the meme coin network’s total hash rate now comes from Litecoin mining pools.

Here are the Scrypt-powered cryptocurrencies that can be mined along with LTC

• Dogecoin (DOGE)
• Gulden (NLG)
• PotCoin (POT)
• FeatherCoin (FTC)
• TagCoin (TAG)
• MidasCoin (MIDAS)]
• GridCoin (GRC)
• VeriCoin (VRC)
• AryaCoin (AYA)

While the above-listed coins can be merge-mined on Litecoin, they are not as widely mined as DOGE has been. 

How To Merge Mine Litecoin (LTC) And Dogecoin (DOGE)?

Merge mining of Litecoin and Dogecoin is possible because both blockchains employ the Scrypt hashing algorithm. This allows miners to solve the cryptographic puzzles for both networks to process transactions and create blocks using the same hardware, thereby earning rewards from both chains.

Here is a step-by-step guide on how to merge mine Litecoin and Dogecoin

Set Up A Compatible Mining Hardware

The first and most important step in merged mining LTC and DOGE is to ensure that your mining rig supports both cryptocurrencies and that the mining software is compatible with the Scrypt algorithm. Here is a list of Litecoin / Dogecoin mining software

• CGMiner
• BFGMiner
• MultiMiner
• EasyMiner
• NiceHash
• Claymore Dual Miner

Select Mining Pool

Next up, you need to join a mining pool that supports merge mining for LTC and DOGE. These pools can combine your hashing power with other miners to increase rewards earned from both blockchains. Some popular mining pools include

• Unified Node Open Mining Portal (UNOMP)
• Kryptex Pool
• Litecoinpool.org

Create Litecoin And Dogecoin Wallets

Before starting the mining process, you will need wallet addresses for both Litecoin and Dogecoin. The wallets can be created through crypto exchanges or wallet services.

Install Mining Software And Configure Mining Hardware

Download and install the mining software on your preferred mining rig and configure the settings. Popular Litecoin and Dogecoin mining machines include

• Bitman Antminer L3++
• Innosilicon A6+
• Goldshell LT6
• iBeLink DM22G

Start Mining

Once your mining rig is configured, it is time to start mining. You can monitor your earnings through the pool’s dashboard and track your LTC and DOGE rewards.

Conclusion

Merge mining Litecoin and Dogecoin is a lucrative opportunity for miners looking to maximize their earnings cost-effectively.
