Proof of Work · ETChash

Mine Ethereum Classic

Ethereum Classic is the world's largest Proof-of-Work smart contract platform, secured by GPU and ASIC miners using the ETChash algorithm. Whether you are setting up your first rig or optimizing an existing operation, this section covers hardware selection, pool options, software configuration, and profitability analysis.

Network Configuration

Production RPC endpoints, chain IDs, and explorer URLs for ETC Mainnet (Chain 61) and Mordor Testnet (Chain 63). Drop-in configuration for MetaMask, Hardhat, Foundry, and any EVM-compatible toolchain. Both networks run Proof-of-Work consensus under the Spiral EVM specification, with the Olympia upgrade pending activation.

Client Software

Client Implementations

Multi-client architecture eliminates single points of failure at the protocol layer. Independent implementations in distinct languages, maintained by separate teams, ensure the network can withstand the discontinuation or compromise of any single codebase. Fukuii, Core-Geth, and ETC compatibility plugins for Besu, Erigon, Go-Ethereum, Nethermind, and Reth provide implementation diversity without fragmenting the ecosystem.

Fukuii

PrimaryOlympia Client

Scala

Ethereum execution layer client in Scala 3 — native Proof-of-Work consensus for Ethereum Classic and Mordor, plus Engine API V1–V4 for post-Merge Ethereum. One binary, four networks. The primary ETC client for the Olympia era.

Mining Algorithm

GPU + ASIC

Compatible Hardware

Ethereum Classic is the only EVM-compatible chain secured by Proof-of-Work. When Ethereum transitioned to Proof-of-Stake, ETC absorbed the majority of the ETHash mining ecosystem, including established ASIC manufacturers like Bitmain and Jasminer. ETChash supports both ASIC efficiency for commercial-grade operations and GPU accessibility for global participation, decentralizing hashrate across geographies and reducing supply chain risk. Run fukuii to participate in block production and earn ETC rewards.

Hardware

Mining Equipment

ETChash supports dedicated ASIC hardware and consumer GPU rigs, distributing hashrate across a broad base of independent operators. ASIC efficiency enables commercial-scale operations; GPU accessibility brings in global retail miners, together diversifying the security budget and reducing single-vendor supply chain risk.

Mining Pools

Mining Pools

Active ETChash mining pools contributing to Ethereum Classic's security budget. Pool selection affects expected earnings variance, payout frequency, and infrastructure dependence. Hashrate is estimated from recent block attribution. Larger pools appear at the top.

Payout types

PPS
Pay Per ShareFixed payout per valid share submitted, regardless of whether the pool finds a block. Variance-free for miners; pool bears the risk.
PPS+
Pay Per Share PlusPPS for the block reward, plus a proportional share of transaction fees. Slightly higher expected earnings than standard PPS.
FPPS
Full Pay Per SharePPS that includes an average of expected transaction fees in the per-share rate. Smooths fee income across all miners.
PPLNS
Pay Per Last N SharesPayout proportional to shares submitted in the most recent window. Rewards consistent miners and discourages pool-hopping.
PROP
ProportionalBlock reward split proportionally among miners who contributed shares to that specific block. Simple, but earnings vary with block luck.
RBPPS
Round-Based Pay Per SharePPS calculated per mining round (block-to-block). Combines the low-variance of PPS with round-scoped accounting.
SOLO
Solo Mining via PoolMiner receives the full block reward if they find a block; nothing if they don't. Pool provides infrastructure only. High variance.

Fee Market

The Fee Market Problem

ETC blocks are currently near ATL utilization. The average block is over 99% empty. Block rewards fifthened every 5M blocks under ECIP-1017. Without fee revenue to replace diminishing block rewards, PoW miners eventually have no financial incentive to secure the network. Olympia is how ETC fixes this: it funds the core development that fills blocks, creates fee revenue, and aligns miners with long-term ecosystem growth.
