Ethereum Classic is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, or interference from third parties. Ethereum Classic consists of a cryptocurrency (ETC), a blockchain ledger, and an ecosystem of applications and services built on top of it.
In short, Ethereum Classic provides a way to manage digital assets without intermediaries like banks and other financial institutions. ETC allows for the writing, deployment, and execution of uncensorable smart contracts; it implements truly unstoppable programmable money. Ethereum Classic is the continuation of the original, non-forked Ethereum (ETH) chain and exists to preserve the principle that “code is law.”
1. Project Introduction
ETC (Ethereum Classic) is a fork of Ethereum that occurred after block 1,920,000, with functionalities very similar to Ethereum. ETC adheres to the principles of decentralization and supports a consensus mechanism guaranteed by the blockchain. ETC firmly believes that once a blockchain begins running, its direction is not dictated by any central team but rather determined by the consensus of those participating in the network and the consensus of the network’s computational power.
In July 2016, a hard fork of the Ethereum blockchain aimed to transfer funds stolen from The DAO to an account controlled by investors, effectively erasing the old transactions from history. Most Ethereum developers participated in this reversal, along with exchanges, startups, and other members of the ecosystem. Within days, the project returned to normal. However, not everyone wanted to forget the old transactions. A small group of miners continued using the original blockchain as a form of protest, describing the hard fork as a bailout of the defunct project, The DAO. Thus, Ethereum Classic (ETC) was born.
Immutability
ETC cannot be altered by others. This characteristic aligns with the ideological creed shared by ETC, Bitcoin, Litecoin, and other cryptocurrencies. Some blockchains subscribe to different ideologies (such as “rule by governance”), which allow participants to vote on others’ account balances based on their social and economic influence, giving the wealthy and famous within the system ultimate control over your money. Such a thing will never happen in ETC; it is fundamental to ETC, as historical precedent has shown.
Efficient Transfer
ETC enables efficient value transfer (more efficient than Bitcoin and other forms of Bitcoin), focusing on Internet of Things applications and operating a mathematically verified Ethereum Virtual Machine (EVM). This means ETC is very much in line with the original vision: becoming an efficient medium of exchange connecting different devices worldwide.
Decentralization
Many blockchain communities have centralized leadership, meaning a small group at the top makes decisions for others. The ETC community structurally avoids this. Responsibility for development and discussion is distributed among various individuals. This avoids the unfair form of “rule by governance,” which can affect other blockchains. ETC’s Internet of Things features are under active development, with implementation expected in the latter half of 2018.
Key Events
July 30, 2015: Ethereum Launch
Vitalik Buterin and the Ethereum Foundation created a blockchain-based Turing-complete smart contract platform.
June 17, 2016: The DAO Attack
Due to a system vulnerability, Ether was stolen from The DAO project. The DAO, one of the hottest projects on Ethereum, raised 150 million dollars worth of Ether. Investors sent funds to The DAO and received voting tokens, allowing them to democratically decide how to use the funds. However, just before voting was to begin, a vulnerability in The DAO’s smart contract was exploited, transferring large amounts of funds to accounts controlled by hackers.
Block 1,920,000 / "Ethereum Implements Hard Fork"
Due to the successful execution of the hard fork code, to recover the stolen funds, the Ethereum team implemented an unconventional state change at block 1,920,000. Most of Ethereums computing power switched to the new version supporting the hard fork.
Block 1,920,001 / Birth of Ethereum Classic
It was originally predicted that the unforked old chain would disappear within hours, but some miners continued to maintain the old chain, and off-exchange trading provided value to the old chain token.
July 23, 2016: Poloniex Exchange Lists ETC Trading
The worlds largest Ethereum exchange supported ETC trading; many other exchanges quickly followed suit, with ETC prices reaching one-third of ETH prices.
July 24, 2016: Ethereum Classic Community Formed
The Ethereum Classic community established its own communication channels, including EthereumClassic, Slack, and Telegram.
Block 3,000,000 / Ethereum Classic Upgrade
ETC completed a non-controversial network upgrade, addressing critical issues such as the “difficulty bomb” and “replay attacks.”
March 1, 2017: Adopted Monetary Policy
The ETC community adopted a monetary policy similar to Bitcoin, limiting the maximum number of coins.
March 1, 2017: ETC Investment Fund
Grayscale Investments wrote an investment guide for the “Ethereum Classic Investment Trust,” the first non-Bitcoin crypto fund targeted at traditional investors.
April 24, 2017: Formation of ECC
The ECC oversees funding supporting ETC, ensuring it is efficiently used for the development of the ETC ecosystem.
April 18, 2018: Official Launch of Ethereum Classic China Community.
Halving Mechanism
On December 11, 2017, ECIP 1017 was published, setting limits on the issuance of ETC: when the block height reaches 5,000,000, the block reward will decrease by 20%, with further reductions every 5,000,000 blocks. Due to changes in ETC rewards, the total supply is estimated to be approximately 210 million ETC, with a maximum of no more than 230 million ETC.
ETC will undergo its first halving at block height 10,000,000, reducing the block reward by 20% to 3.2 ETC. This is expected to occur in March 2020.
2. Commentary
Ethereum Classic (Ethereum Classic) is an open-source, public, distributed computing platform based on blockchain technology with smart contract (scripting) functionality. It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), capable of executing scripts via an international public node network. Ethereum Classic also offers a value token called “Classic Ether,” which can be transferred between participants, stored in cryptocurrency wallets, and used to compensate participant nodes for computation. Classic Ether trades on cryptocurrency exchanges under the ticker symbol ETC. Gas is an internal transaction pricing mechanism designed to prevent spam on the network and allocate resources proportionally based on the incentives offered.
The Ethereum platform forked into two versions: “Ethereum Classic” (ETC) and “Ethereum” (ETH). Before the fork, the token was called Ethereum. After the fork, the new token retained the name Ethereum (ETH), while the old token was renamed Ethereum Classic (ETC). The emergence of Ethereum Classic stemmed from disagreements with the Ethereum Foundation regarding the DAO Hard Fork. It united members of the Ethereum community who philosophically rejected the hard fork. Users who owned ETH before the DAO hard fork (block 1,920,000) had equal quantities of ETC after the fork.
Ethereum Classic underwent a technical hard fork on October 25, 2016, to adjust the internal pricing of various opcodes in the Ethereum Virtual Machine (EVM), similar to the hard fork implemented by Ethereum a week earlier. The purpose of the hard fork was to distribute payments for resource-intensive computations more reasonably, eliminating the previous advantages for attacks on both ETH and ETC. An early 2017 hard fork successfully delayed the “complexity bomb” added to Ethereum’s code in September 2015, intended to exponentially increase the complexity of mining and the process of computing new network units. At the end of 2017, a hard fork changed the unlimited emission monetary policy to one similar to Bitcoin’s system.
