The split occurred after the Decentralized Autonomous Organization (DAO) hack, in which attackers exploited a vulnerability in the DAO’s code, leading to the theft of approximately $50 million worth of Ether.
To recover the stolen funds, the Ethereum community implemented a hard fork, effectively creating a new chain—Ethereum. However, a faction of the community rejected this decision, arguing that blockchain transactions should remain immutable, following the principle of “code is law.” This group upheld the original, unchanged ledger, now known as Ethereum Classic.
As of March, 2025, Ethereum Classic has a market capitalization of approximately $2.85 billion, with a circulating supply of around 150 million ETC tokens. The 24-hour trading volume stands at about $128.97 million, indicating active trading and interest in the cryptocurrency.

3. Differences Between Ethereum Classic vs Ethereum 2.0
The evolution of Ethereum into Ethereum 2.0 has further distinguished Ethereum vs Ethereum Classic, highlighting key differences in scalability, energy efficiency, and governance.
3.1. Consensus Mechanism
One of the most significant differences in Ethereum vs Ethereum Classic lies in their consensus mechanisms. Ethereum transitioned from a Proof-of-Work (PoW) to a Proof-of-Stake (PoS) model with Ethereum 2.0, improving scalability, security, and energy efficiency. In contrast, Ethereum Classic remains committed to PoW, prioritizing decentralization and the immutability of the original blockchain.
3.2. Sharding and Scalability
Ethereum 2.0 aims to address scalability issues through the implementation of shard chains, allowing the network to process multiple transactions simultaneously. This upgrade is expected to significantly increase transaction throughput and reduce fees, enhancing the overall user experience.
Ethereum Classic has not implemented sharding, limiting its transaction capacity and potentially hindering its competitiveness in handling large-scale applications.
3.3. Energy Efficiency
With Ethereum 2.0’s transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS), the network’s energy consumption has drastically decreased, aligning with global sustainability efforts. This shift makes Ethereum a more environmentally friendly option.
Meanwhile, Ethereum Classic continues to operate on PoW, maintaining the high energy demands of traditional mining, which may be a drawback for users and developers concerned about sustainability.
3.4. Governance and Philosophical Differences
Another key distinction in Ethereum vs Ethereum Classic lies in governance and blockchain philosophy. Ethereum’s community embraces upgrades and major protocol changes to improve the network, even if it means altering blockchain history—such as in response to the DAO hack.
In contrast, Ethereum Classic upholds the principle of immutability, emphasizing that blockchain records should never be altered under any circumstances, following the “code is law” ideology.
These differences reflect the distinct paths both blockchains have taken, shaping their roles and use cases in the evolving crypto ecosystem.
