Introduction to Ethereum Classic's Core Geth
Ethereum Classic (ETC) operates as a decentralized network powered by robust node software. Among its primary implementations stands Core Geth, a versatile client-server application that forms the backbone of ETC's blockchain operations.
This fifth installment in our blockchain fundamentals series explores Core Geth's architecture, unique features, and operational capabilities within the Ethereum Classic ecosystem.
Key Components of Ethereum Classic:
- Network: Open-source, permissionless participation
- Blockchain: Fully replicated transaction ledger
- Cryptocurrency: Native ETC coin with secure monetary properties
Core Geth's Technical Architecture

Server-Client Hybrid Model
Unlike traditional client-server systems, Core Geth operates as a peer-to-peer hybrid where:
- All nodes maintain equal status
- Each participant serves as both server and client
- Data propagates through gossip protocol
