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
RecommendedScalaEthereum 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:latestConfiguration
Use network=etc for mainnet, network=mordor for testnet, network=sepolia for Engine API.
Core-Geth
MaintainedGoMaintained — 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
Quick Start
Install

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.
ETC execution plugin for go-ethereum. Adds Ethereum Classic chain support to the most widely deployed EVM client.
ETC execution plugin for Nethermind. Extends the high-performance .NET client with Ethereum Classic support.
ETC execution plugin for Erigon. Brings Ethereum Classic support to the storage-optimized archival client.
ETC execution plugin for Hyperledger Besu. Adds Ethereum Classic chain support to the enterprise-grade Java client.
ETC execution plugin for Reth. Brings Ethereum Classic support to the modular, performance-focused Rust client.
Ready to Run a Node?
Fukuii is the recommended client for Ethereum Classic — native PoW consensus for ETC and Mordor, Engine API V1–V4 for post-Merge Ethereum. For upgrade-specific guidance, see the Olympia client details.
