ETC stands for "Ethereum Classic," a blockchain platform that emerged from a split in the original Ethereum network in 2016. This split occurred due to a disagreement over how to handle a major hack that resulted in the loss of millions of dollars. Ethereum Classic maintains the original blockchain and philosophy of immutability, meaning that transactions cannot be altered or reversed. ETC uses a proof-of-work consensus mechanism, similar to Bitcoin, to validate transactions and secure the network. It allows developers to create decentralized applications and smart contracts, just like its counterpart, Ethereum. The platform aims to provide a stable environment for users and developers who value the principles of decentralization and security.
