ethereum classic, as its name implies, is a network derived from the Ethereum network.
This is one of the most successful forks on the cryptocurrencies network. Of course, bitcoin cash, which is a network derived from the Bitcoin network, has been more successful than ethereum classic in my opinion.
One of the most interesting things about etc is that it itself had a fork. CLO currency. Many forks fail early on, but ethical classics weren't, and that's one reason they can be trusted.
The reason for this fork is that DAO emerged as a sophisticated and revolutionary smart contract for etheruem, but soon after, a security bug was discovered in DAO codes, allowing hackers to make more than $ 50 million. To steal.
