If you've heard of Ethereum, you might assume it was always the only version.

It wasn't.

Ethereum Classic (ETC) is the original Ethereum blockchain — the chain that refused to change its history, even after a massive hack rocked the crypto world in 2016.

In this guide, you'll learn what Ethereum Classic is, why it split from Ethereum, how it works, and how to buy ETC on MEXC today.

Key Takeaways

Ethereum Classic (ETC) is the original Ethereum blockchain, launched July 30, 2015, preserved without alteration after the 2016 hard fork.
ETC has a hard supply cap of 210,700,000 coins — fixed forever, similar to Bitcoin's scarcity model.
Unlike Ethereum, which switched to Proof-of-Stake in 2022, Ethereum Classic still runs on Proof-of-Work and can be mined.
ETC's block reward decreases by 20% every 5 million blocks — an event the community calls the "fifthening."
The network's core philosophy is "code is law": once something is written to the blockchain, it stays there permanently.
As of March 2026, ETC trades around $8.40–$8.60 USD with a market cap of approximately $1.3 billion, according to CoinMarketCap and CoinGecko.

What Is Ethereum Classic (ETC)?

Ethereum Classic is an open-source, decentralized blockchain that runs smart contracts and supports decentralized applications (dApps).

Its native token trades under the ticker ETC, and the network has a hard supply cap of 210,700,000 ETC — a figure set in December 2017 via the Gotham hard fork, following a bitcoin-inspired deflationary emission schedule.

Unlike most blockchains that change course over time, Ethereum Classic holds one core belief above all else: the blockchain's history should never be rewritten.

That philosophy has a name — "code is law" — and it's the reason ETC exists as a separate chain today.

Ethereum Classic History: The DAO Hack That Split a Blockchain

Ethereum launched on July 30, 2015, created by Vitalik Buterin and Gavin Wood.

In 2016, a project called The DAO — a decentralized venture fund built on Ethereum — raised over 11 million ETH from more than 18,000 investors.

The fork came from a hack — read our piece on when Ethereum was created — origins and launch date explained for early history

Then hackers struck. They exploited a smart contract bug and drained roughly $50 million worth of ETH.

The Ethereum community faced a choice: reverse the blockchain to recover the stolen funds, or let the hack stand as a permanent part of history.

The majority voted to reverse it. A hard fork occurred at block #1,920,000 on July 20, 2016 — creating two separate chains. The new, altered chain kept the name Ethereum (ETH). The original, unaltered chain continued as Ethereum Classic (ETC).

Ethereum vs. Ethereum Classic: What's the Difference?

People often ask what is ethereum classic vs ethereum — and the answer goes deeper than just two tickers on an exchange.

1. Consensus Mechanism

Ethereum switched to Proof-of-Stake (PoS) in September 2022 during "The Merge."

Ethereum Classic kept Proof-of-Work (PoW), using its ETChash mining algorithm — the same energy-intensive, competition-based system that Bitcoin uses.

This means ETC can still be mined with GPUs or ASIC hardware, while ETH cannot.

ETC still uses mining — see our guide on how to mine Ethereum — the historical process before the PoS transition
GPU rigs moved here — see our Ethereum miner explained guide — from GPU rigs to Ethereum Classic alternatives

2. Supply Cap

Ethereum has no maximum supply limit — new ETH is issued continuously to validators.

Ethereum Classic is capped at exactly 210,700,000 ETC, making it deflationary by design.

Think of ETC's supply schedule like Bitcoin's — mathematically fixed, immune to political decisions.

3. Philosophy and Governance

Ethereum operates with a core development team that steers its roadmap, which is why it was able to reverse The DAO hack through a coordinated upgrade.

Ethereum Classic follows a decentralized, community-driven model where no single group holds authority — and that's intentional.

The principle of "code is law" means whatever is written into the blockchain stays there, permanently.

4. Smart Contract Compatibility

Both chains support the Ethereum Virtual Machine (EVM), meaning developers can build compatible dApps on either network.

After a series of protocol upgrades — including Atlantis (2019), Phoenix (2020), and Spiral (2024) — Ethereum Classic achieved full EVM parity with Ethereum.

How Does Ethereum Classic Work? Mining, Block Rewards, and Supply

Ethereum Classic uses a Proof-of-Work consensus mechanism, secured by miners competing to validate transactions.

Miners group transactions into blocks, attach a cryptographic stamp, and solve a mathematical puzzle — a process that requires enormous computing power.

When a miner wins, they broadcast the new block to the network and receive a block reward in ETC.

The current block time averages around 13.9 seconds, meaning a new block is added to the chain roughly every 14 seconds.

Every 5 million blocks — approximately every two years — ETC's block reward drops by 20%. The community calls this event the "fifthening," similar to Bitcoin's halving. The most recent fifthening occurred at block 20,000,001 in 2024, reducing the block reward to 2.048 ETC per block.

In 2025, the network's ETChash hashrate surpassed 300 terahashes per second (TH/s) — a milestone that confirms growing miner participation and strengthened network security, according to the Ethereum Classic Wikipedia entry.

Is Ethereum Classic a Good Investment?

This is one of the most common questions new crypto investors ask — and it deserves an honest answer.

Ethereum Classic has real strengths: a fixed supply cap that limits inflation, a Proof-of-Work security model that's been battle-tested, and a loyal global community that has kept the project alive for nearly a decade.

After the 51% attacks in January 2019 and August 2020 — which resulted in losses estimated at over $1.1 million in 2019 and up to $5.6 million in 2020 — the network responded by adopting the ETChash algorithm upgrade (Thanos, November 2020). Since then, the hashrate has grown significantly, reducing the risk of future attacks.

That said, ETC faces real challenges too. It handles between 10 and 20 transactions per second, far below traditional payment networks. And with Ethereum's dominant ecosystem and developer community, ETC competes for a smaller market share.

Whether ETC fits your portfolio depends entirely on your own goals, timeline, and risk tolerance. As of March 2026, ETC trades around $8.40–$8.60 USD, with a market cap of approximately $1.3 billion, according to CoinMarketCap and CoinGecko.

This is not financial advice. Always do your own research before investing.

FAQ

What is Ethereum Classic used for?

Ethereum Classic is used to run smart contracts and decentralized applications (dApps) on a Proof-of-Work blockchain.

Is Ethereum Classic the same as Ethereum?

No — they share a common origin but split in 2016 over a philosophical disagreement about reversing The DAO hack.

Can Ethereum Classic reach $1,000?

It's theoretically possible but highly speculative — ETC's price depends on market conditions, adoption, and broader crypto trends that no one can predict with certainty.

Does Ethereum Classic have a future?

Yes — ETC continues active development, maintains a growing hashrate, and has a consistent base of miners, traders, and supporters worldwide.

Can you mine Ethereum Classic?

Yes — ETC uses Proof-of-Work (ETChash), so it can be mined using compatible GPU or ASIC hardware.

Miners can still work on ETC — read our answer in Can you mine Ethereum? Everything you need to know about the post-Merge reality

What is the difference between Ethereum and Ethereum Classic?

The key differences are consensus mechanism (PoW vs. PoS), supply cap (ETC is capped at 210.7M; ETH has no cap), and governance philosophy.

Is Ethereum Classic a good buy?

It depends on your individual risk tolerance, investment timeline, and research — no prediction can guarantee future performance.

Conclusion

Ethereum Classic isn't a copy of Ethereum — it is the original Ethereum, preserved exactly as it was before the 2016 fork.

It stands for something specific: that blockchain history is permanent, that code should be trusted, and that no single group should be able to rewrite the ledger.

Whether you're a curious beginner or exploring your first ETC trade, MEXC makes it easy to get started with Ethereum Classic today.
