TLDR

Ethereum Classic (ETC) is the original, unaltered Ethereum blockchain that continues to operate as a smart contract platform with an unwavering commitment to the principle of "Code is Law."

  1. Founded on immutability: It originated from a 2016 philosophical split, choosing to preserve the original transaction history without reversals.

  2. Secured by Proof-of-Work: It maintains Bitcoin's mining consensus for security and has a fixed, capped supply of 210.7 million ETC.

  3. A programmable "world computer": It runs the Ethereum Virtual Machine (EVM), enabling developers to build decentralized applications (dApps) and smart contracts.

Deep Dive

1. Philosophical Origin: Upholding "Code is Law"

Ethereum Classic is the original chain that launched in July 2015. Its defining moment came after the 2016 DAO hack, where attackers stole millions in ETH. The community split: Ethereum (ETH) executed a hard fork to reverse the hack, while ETC supporters upheld blockchain immutability, believing code outcomes are final and should not be overridden (CoinMarketCap). This established ETC's core philosophy that no transaction should ever be undone.

2. Conservative Technology: Proof-of-Work & Fixed Supply

ETC deliberately retains the original Proof-of-Work (PoW) consensus mechanism, where miners use computational power to secure the network. This contrasts with Ethereum's shift to Proof-of-Stake. ETC also has a fixed monetary policy with a hard cap of 210,700,000 coins, creating predictable, Bitcoin-like scarcity (Ethereum Classic). These choices prioritize security and censorship resistance over scalability.

3. Core Functionality: A Smart Contract Platform

Despite its conservative base, ETC is fully programmable. It runs the Ethereum Virtual Machine (EVM), meaning it supports smart contracts and dApps just like Ethereum. This makes it a "world computer" where developers can build decentralized finance (DeFi) protocols, tokenized assets, and other applications on a highly secure, immutable foundation.

Conclusion

Ethereum Classic is fundamentally a principles-first blockchain that sacrifices adaptability for maximal security, decentralization, and transactional finality. How will its unwavering commitment to immutability shape its role as a base settlement layer in a rapidly evolving crypto ecosystem?
