Ethereum Classic (ETC)

Ethereum Classic (ETC) is the original Ethereum blockchain that continued without modification after a controversial hard fork in 2016. When the Ethereum community chose to reverse the DAO hack with a fork, a minority rejected the rollback on principle ("code is law") and kept the original chain — which became Ethereum Classic.

Key facts

• Algorithm: EtcHash
• Consensus: Proof of Work

ETC vs ETH

	Ethereum Classic (ETC)	Ethereum (ETH)
Consensus	Proof of Work	Proof of Stake
Mineable	Yes	No
Smart contracts	Yes (EVM compatible)	Yes
Origin	Original chain (2015)	Forked chain (2016)

Post-Merge relevance

After Ethereum switched to Proof of Stake in 2022, a significant portion of former ETH GPU miners moved to ETC as the most direct alternative. ETC's hashrate surged following The Merge.
