Ethereum Classic (ETC) stands as one of the most enduring and philosophically driven blockchains in the cryptocurrency space. With the transition of Ethereum to proof-of-stake through "The Merge," Ethereum Classic has emerged as the largest proof-of-work smart contract platform, preserving the original vision of decentralized, censorship-resistant computation. This shift has also attracted a wave of miners previously dedicated to Ethereum, making ETC mining more competitive and accessible than ever.
In this guide, we’ll explore everything you need to know about mining Ethereum Classic, from hardware and software to mining pools and long-term network security. Whether you're a seasoned miner or just getting started, this resource will help you navigate the ETC ecosystem with confidence.
Why Mine Ethereum Classic?
Ethereum Classic is built on a foundational principle: immutable blockchain integrity. Unlike other networks that may alter history during forks, ETC adheres strictly to the idea that "code is law." This makes it a trusted platform for developers and users who value predictability and decentralization.
The network’s commitment to proof-of-work (PoW) is not just technical—it's ideological. PoW ensures that security comes from distributed computational effort rather than concentrated wealth, reducing centralization risks associated with proof-of-stake systems. For miners, this means ETC offers a sustainable, permissionless environment where anyone can contribute hash power and earn rewards fairly.
Understanding ETC Mining Mechanics
Mining on Ethereum Classic involves validating transactions and securing the network by solving complex cryptographic puzzles. Miners compete to find valid blocks, which are then added to the blockchain. In return, they receive:
- Block rewards (newly minted ETC)
- Transaction fees from included transactions
ETC uses the ETHash algorithm, a memory-hard hashing function nearly identical to Ethereum’s former Ethash. This similarity means that hardware used for Ethereum mining—especially GPUs—is fully compatible with ETC mining.
Because ETC maintains a fixed monetary policy with diminishing block rewards over time, early participation can offer greater returns. The emission curve is designed to incentivize long-term miner support while controlling inflation.
Essential Tools for Mining Ethereum Classic
To start mining ETC effectively, you’ll need three core components: suitable hardware, reliable mining software, and access to a mining pool.
Hardware: Choosing the Right Equipment
Graphics Processing Units (GPUs) remain the most popular choice for ETC mining due to their flexibility and efficiency. High-performance models such as NVIDIA’s RTX 3060 Ti, 3070, and AMD’s RX 6700 XT offer strong hash rates while maintaining reasonable power consumption.
While ASICs exist for some PoW chains, ETC’s ETHash algorithm resists ASIC dominance, helping preserve decentralization by keeping mining accessible to individual operators.
When selecting hardware, consider:
- Hash rate (MH/s)
- Power consumption (watts)
- Cost-to-performance ratio
- Availability and resale value
Always calculate your potential profitability using current electricity costs and ETC market prices before investing in equipment.
Mining Software: Bridging Hardware to Network
Once your hardware is set up, you’ll need mining software to connect your rig to the Ethereum Classic network. Popular options include:
- PhoenixMiner
- T-Rex Miner
- GMiner
- NBMiner
These tools are compatible with both Windows and Linux systems and support multiple algorithms, including ETHash. They provide real-time monitoring, automatic overclocking, and low developer fees (typically 1–2%).
Configuration usually involves entering your wallet address, selecting a mining pool server, and optimizing intensity settings for maximum performance without overheating.

Mining Pools: Increasing Reward Consistency
Solo mining on ETC is highly unlikely to yield consistent returns due to the competitive nature of the network. Joining a mining pool allows miners to combine their hash power and share block rewards proportionally.
Popular Ethereum Classic mining pools include:
- 2Miners
- TitanPool
- Nanopool
- MiningPoolHub
Pools typically charge a small fee (1–3%) and offer features like real-time statistics, low payout thresholds, and secure wallet integration. Be sure to choose a reputable pool with transparent operations and strong uptime.
Frequently Asked Questions (FAQs)
Q: Is Ethereum Classic still mineable after Ethereum’s switch to proof-of-stake?
A: Yes. Ethereum Classic continues to operate on proof-of-work and is now the largest PoW smart contract blockchain. It remains fully mineable using GPU-based rigs.
Q: Can I use my old Ethereum mining rig for ETC?
A: Absolutely. Since ETC uses a nearly identical hashing algorithm (ETHash), any hardware that mined Ethereum pre-Merge can mine ETC with minimal configuration changes.
Q: How often are new ETC blocks mined?
A: Ethereum Classic targets a block time of approximately 13 seconds, ensuring fast transaction confirmations and consistent miner rewards.
Q: What is the total supply of ETC?
A: Unlike inflationary models, ETC follows a fixed issuance schedule with a final cap expected around 230 million coins, promoting scarcity and long-term value retention.
Q: Is cloud mining available for Ethereum Classic?
A: While some third-party platforms offer cloud mining contracts, they often come with high fees and risks. Self-mining gives you full control over operations and profits.
Q: Does ETC plan to switch to proof-of-stake?
A: No. Ethereum Classic has a formal commitment to maintaining proof-of-work indefinitely as part of its core philosophy of immutability and decentralization.
Building a Sustainable Mining Operation
Successful mining isn’t just about buying hardware—it’s about building a sustainable operation. Key considerations include:
- Cooling and ventilation: High-performance GPUs generate significant heat; proper airflow prevents throttling and extends hardware life.
- Power efficiency: Use energy-efficient components and consider renewable energy sources to reduce costs.
- Monitoring tools: Implement remote monitoring software to track performance, detect failures, and adjust settings in real time.
- Wallet security: Store mined ETC in a secure wallet—preferably cold storage—to protect against theft.
Regular maintenance and firmware updates also help maintain optimal performance across your mining farm.
