Ethereum Classic ETC
The older sibling who wouldn't edit the ledger, even after the family name walked out the door with someone else
๐ญ Same parents and same starting block as ETH, then one argument over a single rule split them for good
๐ฌ โPeople always ask if I'm jealous of my brother. The mansion, the crowds, the name everyone knows. No. He got the name; I kept the rule. Ask him to undo a record and he'll do it. Ask me, and I'll just lift the hammer. CLANG. โ๏ธโ
- ETC and ETH are the same coin until one summer day in 2016. Then they split, and ETC is the half that refused to rewrite the ledger.
- ETH took the famous name and later went green (proof-of-stake). ETC kept the old rules: same hammer as Bitcoin (proof-of-work), plus a hard cap of about 210.7 million coins that ETH never had.
- So if you've ever wondered what Ethereum would look like if it had never changed its mind, you're looking at it.
๐ The Story
To understand ETC, you have to understand the fight it lost. Two brothers were born from one chain. The trouble started with a giant shared vault called "The DAO," which a thief drained of roughly 3.6 million ETH in the summer of 2016. The family gathered to decide what to do, and most of them wanted the same thing: "Rewind the ledger. Pretend it never happened. Give everyone their money back."
The younger, louder brother agreed. On July 20, 2016, at block 1,920,000, he edited history and clawed the coins back. He kept the family name, Ethereum, and most of the friends, the developers, and the spotlight went with him. But the older brother wouldn't move. "If we can erase a record just because we don't like it, then it was never really written down. Even a thief's transaction is the truth once it's mined." He stayed on the untouched chain, and four days later, on July 24, an exchange called Poloniex listed that chain under a new ticker. That's how Ethereum Classic (ETC) got its name. He didn't pick it. He inherited it as the consolation prize for being right and outvoted.
For years the gap only widened, and the rivalry took a strange turn in 2022. ETH dropped proof-of-work entirely and switched to proof-of-stake, leaving a whole crowd of miners with nowhere to swing their machines. They came to ETC, the brother who never abandoned the hammer. Overnight he became the largest proof-of-work smart-contract chain in the world, runner-up by fame, but still mining the original ground his brother walked away from.
๐ Stats
๐งฉ How it works
Ethereum Classic builds its blocks by swinging the hammer (proof-of-work, PoW), just like Bitcoin. Miners use their computers to solve hard puzzles and stack new blocks. It also works exactly the way Ethereum does (EVM-compatible), so smart contracts and apps (dApps) can run on it too. At the same time, its issuance is capped so that, like Bitcoin, fewer and fewer new coins are minted over time.
๐ Light & Shadow
- Lost the vote in 2016 but never bent the immutability rule: where ETH chose to rewrite, ETC chose not to
- Has the hard cap ETH lacks (~210.7M, with issuance that shrinks Bitcoin-style over time)
- When ETH abandoned proof-of-work in 2022, the orphaned miners had one obvious home, making ETC the biggest PoW smart-contract chain there is
- The name went to ETH, and so did most of the developers, the apps, and the money. ETC competes against its own brother for attention and usually loses
- While its mining power was thin, attackers seized over half the network and double-spent coins (51% attacks in 2019 and again in 2020)
- "We're the real original" is a great story, but it isn't a reason to build something new here instead of on ETH. That's the gap ETC still has to close
๐งฌ Evolution Lineage
A sibling that split off from Ethereum (ETH) in the July 2016 DAO hard fork. ETC is the original "first" chain, and the side that branched away became today's ETH. It's the same "contentious fork" pattern as Bitcoin Cash (BCH), which split from Bitcoin in 2017.
Note: the other side of that same fork is Ethereum (ETH). A similar contentious split is Bitcoin Cash (BCH, which branched from Bitcoin in 2017).

โ FAQ
- What is Ethereum Classic?
- In 2016, after the "DAO hack," Ethereum split into two chains to reverse the stolen funds. Ethereum Classic is the coin that kept the original chain going, holding to the principle that a blockchain record should never be changed once written (immutability). In short, it's the smart-contract platform that stayed true to the "original Ethereum chain."
- How is it different from Ethereum (ETH)?
- The two are siblings born from the same event. ETC is the "original chain," while the side that broke away became today's ETH (which kept the Ethereum name). In 2022 ETH dropped proof-of-work and switched to proof-of-stake (PoS), and it has no supply cap. ETC, on the other hand, keeps proof-of-work (PoW) like Bitcoin, and its issuance is capped at about 210.7 million coins.
- Why does it have a supply cap?
- In 2017 the "Gotham hard fork" fixed the maximum supply at about 210.7 million coins (210,700,000 ETC). It also uses a "5M20" policy that cuts the mining reward by 20% every 5 million blocks, so, just like Bitcoin, new issuance gradually shrinks over time.
- Where can I buy it?
- On most crypto exchanges. ETC is listed on major platforms like Coinbase, Kraken, and Binance. Prices swing a lot, so only try a small amount for fun. (This is general information, not a recommendation of any exchange or an investment suggestion.)
