Ethereum Classic (ETC) is a forked version of the Ethereum blockchain that emerged as a result of the DAO (Decentralized Autonomous Organization) attack in 2016. It maintains the pre-fork blockchain history and leverages the same core blockchain technology as Ethereum, including smart contracts and a virtual machine. ETC operates on the Proof-of-Work (PoW) consensus mechanism, ensuring decentralization, security, and immutability, while supporting the development of decentralized applications. ETC’s compatibility with Ethereum’s tools makes it easier for developers to migrate smart contracts between the two chains or create new applications.

ETC continues to uphold its founding principle of immutability, where "Code is Law," rejecting any modifications to the blockchain, even after events like the DAO hack. This strong commitment to the original blockchain philosophy distinguishes Ethereum Classic from Ethereum, which rolled back the chain post-hack.

In January 2024, Ethereum Classic underwent the Spiral Hard Fork at block 19,250,000, which improved the network's scalability and performance. While Ethereum has transitioned to Proof-of-Stake (PoS), Ethereum Classic remains committed to Proof-of-Work (PoW), maintaining its original decentralized mining model.

This combination of immutability and continuous development ensures that ETC remains a prominent player in the blockchain ecosystem, preserving the original vision of a decentralized, unalterable ledger.
