Ethereum Classic (ETC)

Last reviewed: June 10, 2026

Ethereum Classic (ETC) is a decentralized blockchain platform that emerged from a split in the Ethereum network. It retains the original Ethereum blockchain's history and is known for maintaining the principle of immutability. This principle emphasizes that once data is recorded on the blockchain, it cannot be altered. As of October 2023, Ethereum Classic continues to operate independently of Ethereum, with its own community and development roadmap. The platform supports smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. Ethereum Classic has integrated with various stablecoins, including Tether (USDT), to enhance its ecosystem.

History

Ethereum Classic originated from a hard fork in the Ethereum network in July 2016. The fork was a response to the DAO (Decentralized Autonomous Organization) hack, where an attacker exploited a vulnerability in the DAO's code, to the loss of approximately $50 million worth of Ether. The Ethereum community was divided on how to address the issue. One group supported a hard fork to reverse the hack and return the stolen funds, while another group opposed altering the blockchain's history, advocating for immutability. The hard fork resulted in two separate blockchains: Ethereum (ETH), which implemented the changes, and Ethereum Classic (ETC), which continued on the original chain.

Technology

Ethereum Classic shares many technological features with Ethereum, as both originated from the same codebase. It supports smart contracts and decentralized applications (dApps), allowing developers to create and deploy applications on its blockchain. Ethereum Classic uses the Ethereum Virtual Machine (EVM), which executes smart contracts and ensures compatibility with Ethereum-based applications. The platform's code is open-source, enabling developers to contribute to its development and improve its functionality.

Consensus Mechanism

Ethereum Classic employs a proof-of-work (PoW) consensus mechanism, similar to Bitcoin. In PoW, miners solve complex mathematical problems to validate transactions and add new blocks to the blockchain. This process requires significant computational power and energy consumption. The PoW mechanism ensures the security and integrity of the network by making it difficult for malicious actors to alter the blockchain. Ethereum Classic has considered transitioning to a proof-of-stake (PoS) mechanism, which is more energy-efficient, but as of October 2023, it continues to use PoW.

USDT Integration

Ethereum Classic has integrated with Tether (USDT), a popular stablecoin pegged to the US dollar. Stablecoins like USDT provide stability in the volatile cryptocurrency market, making them attractive for transactions and as a store of value. The integration allows users to transact USDT on the Ethereum Classic blockchain, leveraging its security and immutability. This integration enhances the platform's utility and attracts users who prefer stable assets for their transactions.

Ecosystem

The Ethereum Classic ecosystem comprises developers, miners, and users who support its principles and contribute to its growth. The platform hosts various dApps and projects, ranging from decentralized finance (DeFi) to non-fungible tokens (NFTs). Although smaller than Ethereum's ecosystem, Ethereum Classic's community is dedicated to maintaining its independence and promoting its unique value proposition. The platform's compatibility with Ethereum-based applications allows developers to port their projects to Ethereum Classic with minimal modifications.

Governance

Ethereum Classic's governance is decentralized, with decisions made through community consensus. The platform does not have a formal governance structure or a centralized authority. Instead, stakeholders, including developers, miners, and users, participate in discussions and propose changes to the network. Ethereum Classic Improvement Proposals (ECIPs) are used to suggest and implement changes, similar to Ethereum's Ethereum Improvement Proposals (EIPs). This decentralized governance model aligns with Ethereum Classic's commitment to immutability and resistance to centralized control.
