Why Classic?

Ethereum Classic is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.

Ethereum Classic is a continuation of the original Ethereum blockchain - the classic ‘unforked’ version; free from external interference and subjective tampering of transactions.

Transaction Finality

We believe the core value proposition of any blockchain is immutability; valid transactions can never be erased or forgotten. Individuals interacting on Ethereum Classic are governed by this reality; Code is Law.

This does not necessarily mean that code replaces existing laws, or that only code is law (there are many geographical jurisdictions), but it gives users the opportunity to enter into a new blockchain-based jurisdiction where agreements are governed by code.

By entering into contracts on Ethereum Classic, you can be certain that the network remains neutral. The outcome of transactions will be dictated by code you voluntarily interact with. Unless explicitly defined by the contract code, there are no reversals, no undos, no opt-outs.

Transactions are final; applications are unstoppable.

Decentralized Governance

There are many problems that fester due to centralization and opaqueness; corruption, unaccountability, nepotism, inefficiency and stagnation. Ultimately, centralization leads to fragility; only decentralized systems can stand the test of time.

These problems can be only solved by adhering to governance systems that do not rely on a central point of failure. Just like distributed networks and the consensus protocol itself, we believe that only truly decentralized projects can survive in the long run.

Ethereum Classic manifests these values by relinquishing control by a formalized central foundation. The only hierarchy is that of transparent meritocracy and mutual reputation. No backroom deals or behind-closed-doors unilateral decision making; just free and open discourse.

To Be Continued

As both communities begin to refocus efforts on development, despite an uncertain future, we reflect on mistakes of the past and look ahead at future potentials...

Ethereum Classic Community

Thousands of individuals united by the promise of immutability


Fun fact. Everyone who had legacy ETH in your wallet pre-fork, now has an extra ‘bonus’: you have the same amount of classic ether (ETC) on the same address.

Blockchain technology exists to serve the people, and this can only be achieved fairly and effectively if the the network is neutral to which transactions get processed. In the long run, only applications that run this way will be truly trustless, and we need the help of everyday users to grow the network and create demand for useful dapps.


Progression of technology is the fundamental motivating factor of developer adoption. Ethereum Classic represents another chance to continue the development of the original, world-changing, decentralized, turing-complete smart contract platform.

From newbies to professionals, whether you’re a protocol dapp, web or native developer, the Ethereum Classic community always welcomes you help continue the vision.


The hard fork created a huge opportunity for miners, creating two fluctuating currencies to switch their rigs between. Ethereum Classic is presently one of the most profitable crypto-currencies to mine and is attracting substantial hash power with zero switching cost.

With your help, the Ethereum Classic network can grow strong and you will be rewarded for ensuring the future of the original chain. Do it for profit and principles; mine Ethereum Classic today!


Those who understand the core value proposition of blockchain have a unique opportunity to invest in the growth of the original Ethereum vision. Before the fork, Ethereum was valued at around $20 USD.

Using the exact same technology with an untampered chain, Ethereum Classic is presently valued at around $2 USD, and many investors expect an eventual full recovery and surpassing of pre-fork valuations. Don’t miss out on this unique opportunity.
