How to mine Ethereum Classic after the merge? (Tutorial)

Understanding Ethereum Classic’s Post-Merge Landscape

1. Ethereum Classic remained a proof-of-work blockchain after the Ethereum mainnet transitioned to proof-of-stake in September 2022.

2. The network did not undergo any consensus-layer upgrade or fork that altered its mining mechanism.

3. Miners retained full ability to validate blocks using computational hashing power, specifically Keccak-256.

4. Block time stabilized around 13–15 seconds, with difficulty adjustments occurring every block to maintain consistency.

5. Network hash rate experienced volatility immediately post-merge but gradually recovered as displaced ETH miners redirected hardware toward ETC.

Hardware and Software Requirements

1. GPU-based mining remains the dominant and most accessible method; NVIDIA and AMD cards with at least 4GB VRAM are viable.

2. Older generation GPUs such as GTX 1060, RX 570, and RX 580 continue to produce profitable hashrates under current network conditions.

3. Mining software options include T-Rex Miner, PhoenixMiner, and GMiner—each supporting ETC’s Ethash variant (ETChash).

4. ETChash requires DAG file generation, which grows over time; systems must allocate sufficient SSD space and RAM for efficient loading.

5. Linux-based rigs often deliver higher stability and lower overhead than Windows setups, especially for large-scale operations.

Setting Up a Mining Rig

1. Install compatible GPU drivers—NVIDIA 470+ or AMD Adrenalin 22.5.1+ recommended for optimal kernel compatibility.

2. Download and configure a miner binary, specifying pool URL, wallet address, and worker name via command-line flags or config files.

3. Choose a reliable mining pool such as Ethermine, Hiveon, or Nanopool—each offering low fees, transparent payout structures, and real-time dashboard metrics.

4. Ensure firewall settings allow outbound connections on the pool’s designated port (typically 3333 or 4444) and verify SSL/TLS certificate trust if using secure endpoints.

5. Monitor rig performance using tools like MSI Afterburner or Netdata to track GPU temperature, fan speed, power draw, and rejected share rates.

Wallet Configuration and Payout Management

1. Use an ETC-compatible wallet such as MetaMask, Trust Wallet, or the official Ethereum Classic Electron Wallet to store mined rewards.

2. Generate a new receiving address and verify checksum compliance—ETC addresses follow the same format as Ethereum but operate on a separate chain.

3. Configure pool payout thresholds carefully; too low may trigger excessive small transactions, while too high delays liquidity access.

4. Enable two-factor authentication on pool accounts and store wallet seed phrases offline in tamper-evident media.

5. Regularly audit transaction history on ETC explorers like Blockscout or ETCScan to confirm block confirmations and finality status.

Frequently Asked Questions

Q: Can ASIC miners be used for Ethereum Classic mining?Yes. Devices such as Bitmain Antminer E9 and Innosilicon A10 Pro support ETChash and remain competitive due to their optimized memory bandwidth and power efficiency.

Q: Is cloud mining for ETC trustworthy?Most cloud mining services lack verifiable infrastructure and often obscure operational details. Direct hardware control remains the only method ensuring transparency and full reward entitlement.

Q: Why do some pools report stale shares more frequently than others?Stale shares increase when network latency exceeds block propagation time or when local system clocks drift significantly from NTP-synchronized reference servers.

Q: Does Ethereum Classic support merged mining with other chains?No. ETC does not currently implement any merged mining protocol. Its PoW implementation is standalone and not cryptographically linked to auxiliary blockchains.
