Ethereum Classic (ETC) is a decentralized, open-source blockchain platform that was created as a result of a hard fork from the original Ethereum blockchain in 2016. The fork was a result of a disagreement within the Ethereum community over how to handle a hack that resulted in the loss of millions of dollars worth of Ether. The Ethereum Classic blockchain is designed to be immutable, meaning that once a transaction is recorded on the blockchain, it cannot be altered or deleted. This makes it a popular choice for applications that require a high level of security and transparency, such as supply chain management and voting systems.

ETC is the native cryptocurrency of the Ethereum Classic blockchain and is used to pay for transaction fees and to incentivize miners to validate transactions on the network. Like other cryptocurrencies, ETC can be bought and sold on various exchanges and can be stored in a variety of wallets. ETC has a fixed supply of 210 million coins, which means that there will never be more than 210 million ETC in circulation. This fixed supply, combined with the immutability of the blockchain, makes ETC a popular choice for investors who are looking for a long-term store of value.
