Ethereum Classic (ETC) has solidified its position as the largest Proof of Work (PoW) smart contract platform following Ethereum's transition to Proof of Stake (PoS), an event widely known as "The Merge." This shift has led a significant portion of the mining community, previously dedicated to Ethereum, to migrate their operations to Ethereum Classic. Thanks to its use of the Ethash algorithm, which is nearly identical to Ethereum's, ETC supports the same mining hardware, making the transition a straightforward process of connecting to a pool that supports ETC.
This guide provides a comprehensive overview of the mining resources available for Ethereum Classic.
Why Mine Ethereum Classic?
Ethereum Classic is fundamentally committed to the long-term use of Proof of Work consensus. This mechanism is a time-tested, robust foundation for building unstoppable applications. This commitment is a deliberate design choice, prioritizing proven security and decentralization over other mechanisms like Proof of Stake, which involve different and often complex security trade-offs.
Mining is a critical component of any Proof of Work blockchain. It provides the necessary security that allows the distributed network of nodes to achieve consensus on the state of the blockchain. In exchange for contributing this essential service, anyone in the world can permissionlessly contribute their hashing power. Miners are rewarded with ETC for each block they mine, receiving both new coins from the emission curve and any transaction fees included in the block.
Essential Mining Resources for ETC
Getting started with Ethereum Classic mining requires a few key components. Here is a non-exhaustive list of resources to guide you.
Hardware Requirements
The primary requirement for mining ETC is a Graphics Processing Unit (GPU). Since ETC uses the Ethash algorithm, it is best mined with GPUs that have sufficient video memory (VRAM). Application-Specific Integrated Circuits (ASICs) designed for Ethash are also compatible and can offer higher hash rates.
Choosing Mining Software
Mining software acts as the bridge between your hardware and the blockchain network. You will need to select a program that is compatible with your GPU or ASIC hardware and supports the Ethash algorithm. Popular options include open-source clients that are widely used within the community.
Connecting to a Mining Pool
While solo mining is possible, it is highly impractical for most due to the high level of competition. Joining a mining pool, where miners combine their computational power to increase the chances of finding a block and share the rewards, is the standard approach. You will need to choose a reliable pool that supports Ethereum Classic.
Configuring Your Wallet
To receive your mining rewards, you need a secure ETC wallet address. This address is entered into your mining software configuration. It is crucial to use a wallet you control, such as a hardware wallet, a software wallet, or a verified mobile wallet, ensuring you have access to your private keys.

Frequently Asked Questions
What is the best hardware for mining ETC?
High-performance GPUs with at least 6GB of VRAM are typically the best starting point for most individual miners. The specific model will depend on your budget and desired balance between hash rate and energy efficiency.
How do I calculate my potential profitability?
Mining profitability depends on several factors: your hardware's hash rate, the network's current difficulty, the price of ETC, and your electricity cost. Numerous online calculators allow you to input these variables for an estimate.
Is mining Ethereum Classic still profitable?
Profitability fluctuates constantly with market conditions. While the migration of miners has increased network security and potentially the value of ETC, it has also increased mining difficulty. Always conduct a thorough cost-benefit analysis before investing in equipment.
What is the difference between ETC and ETH mining?
The core technical process is identical because both originally used the Ethash algorithm. The primary difference now is that Ethereum has moved to Proof of Stake, so ETH can no longer be mined, whereas ETC continues to operate on Proof of Work.
Can I use my old Ethereum mining setup for ETC?
Yes, absolutely. Since both chains used the same algorithm, any GPU or Ethash ASIC rig that was mining Ethereum can be easily repurposed to mine Ethereum Classic by simply switching to an ETC-supporting pool.
Where can I get help if I have mining issues?
The Ethereum Classic community is very active and supportive. For technical questions and troubleshooting, the dedicated mining channel on the Ethereum Classic Discord server is an excellent resource for real-time assistance.
