Ethereum Classic is an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality. It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum Classic also provides a value token called "classic ether", which can be transferred between participants and is used to compensate participant nodes for computations performed. The classic ether token is traded on cryptocurrency exchanges under the code ETC. Gas, an internal transaction pricing mechanism, is used to prevent spam on the network and allocate resources proportionally to the incentive offered by the request.

Ethereum Classic appeared as a result of disagreement with the Ethereum Foundation regarding The DAO Hard Fork. It united members of the Ethereum community who rejected the hard fork on philosophical grounds. Users that owned ETH before the DAO hard fork (1900000th block) received the same amount of ETC after the fork.

Ethereum Classic passed a technical hard fork to adjust the internal prices for various opcodes of the Ethereum Virtual Machine (EVM) on October 25, 2016, similar to the hard fork committed by Ethereum a week previously. The purpose of the hard fork was a more rational distribution of payments for resource-intensive calculations, which led to the elimination of the favorable conditions for attacks that were previously conducted on ETH and ETC. A hard fork held in the beginning of 2017 successfully delayed the "bomb complexity" that was added to the Ethereum code in September 2015 with a view of exponentially increasing the complexity of mining and the process of calculation of new network units. The next hard fork is scheduled for late 2017 with the aim of changing the monetary policy with unlimited emissions to a system similar to Bitcoin.

In May of 2016, a venture capital fund called The DAO built on Ethereum raised around $168 million, with the intention of investing in projects using smart contracts. In the same month a paper was released detailing security vulnerabilities with The DAO that could allow ether to be stolen. In June, 3.6 million Ether (approximately $50 million USD) was taken from accounts in The DAO and moved to another account without the owners' consent, exploiting one of the vulnerabilities that had been raised in May. Members of The DAO and the Ethereum community debated what actions, if any, should occur to resolve the situation. A vote occurred and in July 2016 it was decided to implement a hard fork in the Ethereum code and to move the Ether taken in the exploit to a new smart contract through which it would be restored to the owners from whom it had been taken.
