Run Your Own Node

ETC Node Clients

Run your own Ethereum Classic node for maximum decentralization and independence. Choose from multiple client implementations in Go, Java, and Scala.

Why Run Your Own Node?

Full Verification

Independently verify every transaction and block without trusting third parties.

Privacy

Your transactions and queries stay private - no external RPC provider sees your activity.

Network Support

Help strengthen the ETC network by adding another independent node.

Reliable Access

Never depend on external services for blockchain access - your node is always available.

Available Clients

Fukuii

RecommendedScala

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. Pairs with Lighthouse, Prysm, Teku, Lodestar, or Nimbus to run Sepolia and ETH mainnet. One binary, four networks. The primary ETC client for the Olympia era.

Features

  • SNAP, fast, and regular sync for ETC and Mordor
  • Engine API V1–V4 — Sepolia validated, ETH mainnet ready
  • Compatible with all major consensus clients
  • Signed Docker images on GHCR
  • JSON-RPC, Engine API, and MCP support

Quick Start

Install

docker pull ghcr.io/chippr-robotics/fukuii:latest

Configuration

Use network=etc for mainnet, network=mordor for testnet, network=sepolia for Engine API.

Core-Geth

MaintainedGo

Maintained — Established go-ethereum fork with all known security patches applied for the Olympia transition. Maintained through the upgrade period as the network transitions to Fukuii as the primary client.

Features

  • Full and light sync modes
  • JSON-RPC and WebSocket APIs
  • EVM tracing and debugging
  • Built-in mining support
  • MEV-free transaction ordering

Execution Client Plugins

Post-Olympia Roadmap

Upstream Ethereum clients separated the consensus engine from the execution engine to support Proof-of-Stake. ETC plugins leverage this separation to add Ethereum Classic chain support to the execution layer only. No mining, no PoW consensus. Products and infrastructure built on Go-Ethereum, Nethermind, Erigon, Besu, or Reth can add ETC support via a lightweight plugin without running a separate PoW consensus client. Fukuii remains the primary and long-term supported Proof-of-Work client for the mining ecosystem.
