With Ethereum’s transition to Proof of Stake—commonly referred to as "the Merge"—now complete, Ethereum Classic (ETC) has emerged as the largest Proof-of-Work (PoW) smart contract platform in the blockchain ecosystem. As a result, it has inherited a significant portion of the global mining community previously dedicated to Ethereum. Thanks to its nearly identical hashing algorithm, ETCash (a variant of Ethash), Ethereum Classic supports the same mining hardware used for Ethereum, making the switch for miners both seamless and efficient.
This shift presents a unique opportunity for miners seeking a stable, secure, and decentralized network that continues to embrace the original principles of blockchain technology. In this guide, we’ll explore the essential mining resources for Ethereum Classic, explain why PoW remains a cornerstone of trustless systems, and provide practical steps to get started.

Why Mine Ethereum Classic?
Ethereum Classic is built on a foundational commitment to Proof of Work, a consensus mechanism proven over decades to offer robust security and resistance to censorship. Unlike newer models such as Proof of Stake, which rely on economic stakes and can centralize control among wealthy validators, PoW ensures that network security is directly tied to computational effort—anyone with hardware can participate.
This design choice isn’t accidental; it’s philosophical. Ethereum Classic adheres to the principle of “code is law,” maintaining immutability and decentralization above all else. By preserving PoW, ETC offers:
- Decentralized security: No single entity controls validation.
- Permissionless participation: Anyone can mine without approval.
- Predictable issuance: A fixed supply cap and transparent emission schedule.
- Hardware inclusivity: Consumer-grade GPUs remain effective.
These attributes make Ethereum Classic not just a viable alternative, but a preferred destination for miners exiting the post-Merge Ethereum landscape.
Getting Started with ETC Mining
Mining Ethereum Classic requires three core components: hardware, software, and a mining pool.
1. Hardware Requirements
Since ETC uses an Ethash-based algorithm (ETCASH), it is ASIC-resistant and optimized for GPU mining. Most modern graphics cards from NVIDIA and AMD are compatible. Recommended setups include:
- NVIDIA: RTX 3060 Ti, 3070, 3080, or higher
- AMD: RX 6700 XT, 6800, or 6900 XT
A typical rig might consist of 6–8 GPUs connected via risers to a motherboard with sufficient PCIe lanes. Memory bandwidth and VRAM (at least 6GB per card) are critical for optimal performance.
2. Mining Software
Several well-maintained mining clients support ETCASH. Popular options include:
- PhoenixMiner
- GMiner
- T-Rex Miner
- NBMiner
These tools are lightweight, offer high efficiency, and support auto-tuning features to maximize hash rates while minimizing power consumption.
3. Joining a Mining Pool
Solo mining is impractical due to difficulty variance. Instead, most miners join pools that aggregate hash power and distribute rewards proportionally. Reliable Ethereum Classic mining pools include:
- 2Miners
- TitanPool
- Nanopool
- HashrateMarket
When choosing a pool, consider factors like fee structure (typically 0.5%–1%), payout thresholds, server locations, and uptime.

Core Mining Keywords and Their Importance
To help you navigate the ecosystem effectively, here are key terms every ETC miner should understand:
- Proof of Work (PoW): The consensus mechanism securing the network through computational effort.
- ETCASH: Ethereum Classic’s memory-hard hashing algorithm, derived from Ethash.
- Mining Pool: A collective of miners who combine hash power to increase block discovery frequency.
- Hash Rate: The total computational power dedicated to mining on the network (measured in MH/s).
- Block Reward: Currently 2.56 ETC per block, plus transaction fees.
- Decentralization: A core value of ETC, ensured by open participation in mining.
- GPU Mining: The use of graphics processing units to solve cryptographic puzzles.
- Emission Curve: The predictable schedule by which new ETC tokens are released.
Understanding these concepts ensures informed decision-making and long-term success in the mining space.
Frequently Asked Questions (FAQ)
Q: Is Ethereum Classic still mineable after Ethereum’s Merge?
A: Yes—unlike Ethereum, which has moved to Proof of Stake, Ethereum Classic continues to operate under Proof of Work, making it fully mineable using GPU rigs.
Q: Can I use my old Ethereum mining rig for ETC?
A: Absolutely. Since both networks use similar hashing algorithms (Ethash/ETCASH), your existing hardware can be repurposed with minimal configuration changes.
Q: How much can I earn mining ETC?
A: Earnings depend on your hash rate, electricity costs, pool fees, and ETC’s market price. Online calculators like WhatToMine or MinerStat can estimate profitability based on current network conditions.
Q: Is there a risk of a 51% attack on ETC?
A: While smaller than Ethereum pre-Merge, ETC’s network has seen increased hash rate since the Merge. The community actively monitors security, and multiple exchanges enforce deeper confirmations to mitigate risks.
Q: Does ETC plan to switch to Proof of Stake?
A: No. Ethereum Classic is committed to maintaining Proof of Work indefinitely as part of its core philosophy of immutability and decentralization.
Q: Where can I get technical support for mining?
A: The Ethereum Classic Discord hosts an active mining channel where developers and experienced miners provide real-time assistance.

Final Thoughts
Ethereum Classic stands as a beacon for those who believe in the original vision of blockchain: decentralized, immutable, and secured by open participation. As the largest surviving Proof-of-Work smart contract platform, it offers a rare combination of historical significance, technical robustness, and economic opportunity.
For miners displaced by Ethereum’s transition, ETC represents not just a fallback—but an upgrade in ideological alignment and long-term sustainability. With accessible entry points, strong community support, and growing network security, now is an ideal time to contribute your hash power to this enduring network.
Whether you're setting up your first rig or scaling an existing operation, the tools, pools, and knowledge base are readily available. Mining Ethereum Classic isn’t just about earning tokens—it’s about supporting a blockchain that values transparency, resilience, and freedom.
By integrating efficient software, reliable pools, and a clear understanding of PoW principles, you position yourself at the forefront of a movement that continues to prove that decentralization isn’t obsolete—it’s evolving.
