Ethereum Classic (ETC) is a decentralized, open-source blockchain platform that enables developers to build and deploy smart contracts and host decentralized applications (dApps). Established in 2016 as a result of The DAO hack, Ethereum Classic emerged from a philosophical divide within the Ethereum community. While the majority opted to reverse the hack and restore stolen funds, a minority upheld the principle that "code is law," leading to a split that created two separate blockchains.
The History of Ethereum Classic
The original Ethereum blockchain was designed as a unified network facilitating transactions through its native cryptocurrency, ETH. It quickly gained popularity during the initial coin offering (ICO) boom, with numerous teams leveraging the platform to launch their tokens.
One of the most notable ICOs was The DAO, a decentralized venture fund where investors collectively voted on asset allocations. The DAO raised over 11 million ETH from more than 18,000 investors. However, an unknown hacker exploited a vulnerability in its smart contract, draining approximately one-third of the accumulated Ether.
The scale of the attack prompted intense debate. Some investors proposed reversing the blockchain to recover the funds, while others argued that doing so would undermine blockchain immutability and set a dangerous precedent. After a community vote, 97% supported a hard fork to restore the lost assets.
This decision resulted in the Ethereum blockchain splitting into two distinct networks: the new chain retained the Ethereum name and continued using ETH, while the original chain became Ethereum Classic, adopting ETC as its native currency.
How Does Ethereum Classic Work?
Ethereum Classic operates similarly to Ethereum, relying on a blockchain that facilitates not only payments but also smart contracts and decentralized applications. Its Turing-complete programming language allows developers to create automated applications governed by conditional outcomes.
Like other blockchains, Ethereum Classic maintains a complete, immutable record of all transactions in a shared database. It also tracks the latest state of all smart contracts and user balances, enabling seamless digital transfers between wallets. All network activities are powered by ERC-20 tokens, which are mined through a Proof-of-Work (PoW) consensus mechanism. Notably, Ethereum Classic will not adopt the ETH 2.0 upgrade.
Ethereum Classic vs. Ethereum
Although both platforms originated from the same codebase, Ethereum Classic has since distinguished itself through key technical and philosophical differences.
The most significant distinction is Ethereum Classic’s commitment to maintaining the Proof-of-Work mining system, pioneered by Bitcoin, to secure its blockchain. In contrast, Ethereum has transitioned to a Proof-of-Stake (PoS) consensus mechanism.
Another critical difference lies in their monetary policies. Ethereum Classic has a fixed supply cap of 230 million ETC, introducing a scarcity factor that influences its value. Ethereum, on the other hand, does not have a hard supply limit.
Advantages of Ethereum Classic
Ethereum Classic offers all the benefits of blockchain technology, along with several unique advantages:
- Immutability: Once recorded, transactions cannot be altered, deleted, or modified. This commitment to immutability ensures high levels of decentralization, security, and code integrity.
- Decentralization: By relying on Proof-of-Work consensus, Ethereum Classic eliminates the need for intermediaries or central authorities. Transactions occur peer-to-peer, and smart contracts are self-executing.
- Fast Transaction Speeds: Automated verification processes enable quick transaction processing and validation, reducing reliance on third parties and lowering costs.
- High Reliability: For over five years, the Ethereum Classic blockchain has consistently supported applications, smart contracts, and transactions without downtime, fraud, or censorship.
- Programmability: Developers can build decentralized applications and smart contracts for diverse use cases, including financial services, gaming, and automated agreements.
Is Ethereum Classic Secure?
Every transaction on the Ethereum Classic blockchain is secured through cryptographic encryption. The network’s distributed node structure ensures rapid transaction validation and resilience against attacks. Most security vulnerabilities target poorly coded dApps or smart contracts rather than the blockchain itself. However, since Ethereum Classic continues using Proof-of-Work, it does not benefit from the enhanced security features of Ethereum’s Proof-of-Stake model.

Frequently Asked Questions
What is the main difference between Ethereum and Ethereum Classic?
Ethereum Classic adheres to the original "code is law" philosophy and uses Proof-of-Work, while Ethereum transitioned to Proof-of-Stake and implemented changes to reverse The DAO hack.
How is Ethereum Classic mined?
ETC is mined using the Proof-of-Work consensus algorithm, similar to Bitcoin. Miners use computational power to solve complex mathematical problems and validate transactions.
What is the total supply of ETC?
Ethereum Classic has a fixed supply cap of 230 million ETC, creating a deflationary economic model.
Can I use the same wallet for Ethereum and Ethereum Classic?
No, due to their different blockchains, each cryptocurrency requires a compatible wallet. Using the wrong wallet may result in permanent loss of funds.
Is Ethereum Classic a good investment?
Investment decisions should be based on individual research and risk tolerance. Consider factors like technology, market trends, and project developments before investing.
