There has been a lot of confusion among relatively new people in this space about which is the original Ethereum, which one has a future, and why there are two Ethereums..... Ethereum Classic’s blockchain is the same in every way with Ethereum’s until Block 192000, where the hard fork was applied.
Ethereum Classic (ETC) is also a decentralized programmable blockchain like Ethereum. And like ETH, ETC is traded on exchanges and offers the same functionality of decentralized apps and smart contracts as Ethereum (ETH). Eth had to go through a needed fork in order to help reinstate that belief in Blockchain, after the DOA fiasco.
