Ethereum Classic (ETC) is a cryptocurrency that was created in 2016 as a result of a hard fork of the Ethereum blockchain. The hard fork was a response to a hack of the Ethereum blockchain that resulted in the loss of approximately $50 million worth of Ether, the native cryptocurrency of the Ethereum blockchain. The Ethereum Classic blockchain operates similarly to the Ethereum blockchain, allowing for the creation and execution of smart contracts and decentralized applications (dapps). However, there are some key differences between the two blockchains, including the approach to immutability and the treatment of certain historical events. The purpose of Ethereum Classic is to provide a secure and decentralized platform for the creation and execution of smart contracts and decentralized applications, enabling developers and businesses to build and deploy a wide range of applications on a secure and decentralized infrastructure.
