The upcoming transition of Ethereum from Proof-of-Work (PoW) to Proof-of-Stake (PoS), known as the Merge, has sparked considerable discussion within the blockchain community. One notable point of interest is how this shift will affect Ethereum Classic (ETC), which shares a common origin with Ethereum but has since evolved differently.
In a recent address, Vitalik Buterin, one of Ethereum's co-founders, mentioned that those who prefer PoW could consider using Ethereum Classic, describing it as a viable public blockchain. This statement has drawn attention to ETC, especially as Ethereum miners currently relying on GPU setups seek alternatives to maintain profitability post-Merge.
While Ethereum mining remains profitable for now, the full transition to PoS will eventually make ETH mining obsolete. This has led many miners to explore other options, with ETC being a natural candidate due to its similar hashing algorithm. But what does Ethereum's Merge truly mean for Ethereum Classic in the long run? Let’s explore.
The History of Ethereum and Ethereum Classic
Ethereum (ETH) is the second-largest cryptocurrency by market capitalization and hosts the largest ecosystem of decentralized applications (DApps). Its smart contract functionality revolutionized blockchain technology, enabling innovations across decentralized finance (DeFi), NFTs, and more.
Ethereum Classic (ETC), on the other hand, is the original Ethereum blockchain that persisted after a significant ideological and technical split. The division occurred in response to the infamous DAO hack in 2016, where millions of dollars in ETH were stolen. To recover the stolen funds and address security vulnerabilities, the majority of the community supported a hard fork, creating the new Ethereum chain (ETH). A minority opposed the fork, advocating for the immutability of the blockchain, and continued to support the original chain, which became Ethereum Classic (ETC).
Since the split, Ethereum has grown into a globally dominant platform for DApps and smart contracts, while Ethereum Classic has maintained a smaller, niche presence.
Similarities Between ETH and ETC
Despite their differences, ETH and ETC share some technical commonalities:
- Consensus Mechanism: Both currently use Proof-of-Work, though Ethereum is transitioning fully to Proof-of-Stake.
- Smart Contract Support: Both platforms support smart contracts and host DApps.
- Transaction Throughput: Both are capable of processing around 15–20 transactions per second (TPS), though actual usage varies significantly.
These similarities have made ETC a logical alternative for ETH miners, but the differences between the two are substantial.
Key Differences Between ETH and ETC
Philosophical Approach
Ethereum Classic operates under the motto “Code is Law,” emphasizing blockchain immutability above all. This principle stems from its origin story and reflects a commitment to maintaining the original chain without alterations.
Ethereum takes a more flexible approach, allowing upgrades and forks to improve functionality, enhance security, or adapt to community needs. This flexibility has enabled innovations like the upcoming Merge.
Security Record
Ethereum has maintained a strong security profile despite being a frequent target for attacks due to its size and value. The network has effectively managed risks through upgrades and community governance.
Ethereum Classic, however, has suffered multiple 51% attacks, notably in 2019 and 2020. These incidents undermined confidence in the network, leading some exchanges to delist ETC temporarily.
Supply Mechanism
ETH has no hard cap on its total supply, though its current inflation rate is low (around 0.5%). In contrast, ETC has a fixed maximum supply of 210.7 million coins and implements periodic reward reductions to control inflation.
Despite this, ETC’s current annual inflation rate is approximately 5%, significantly higher than ETH’s.
DApp Ecosystem and Adoption
Ethereum hosts over 3,000 DApps with a total value locked (TVL) exceeding $100 billion. Its ecosystem is diverse, encompassing DeFi, NFTs, gaming, and more.
Ethereum Classic supports only a few dozen DApps, with a TVL of around $100 million—more than a thousand times smaller than Ethereum’s.
Transaction Speed and Costs
While both networks have similar theoretical TPS limits, Ethereum often operates near full capacity (around 15 TPS), whereas ETC averages about 1 TPS.
Transaction fees on ETC are significantly lower—often less than a cent—compared to Ethereum, where fees can range from $10 to $50 during peak times.
How the Ethereum Merge Affects ETC
The Merge is expected to impact ETC in several ways:
- Miners Migrating to ETC: With Ethereum moving away from PoW, miners are likely to shift their resources to ETC, potentially increasing its hashrate and security.
- Short-Term Interest and Volatility: The Merge may generate speculative interest in ETC, leading to short-term price volatility.
- Long-Term Viability: While increased mining activity could strengthen ETC’s network, its long-term success depends on addressing security issues and expanding its utility.
However, it’s important to note that the Merge does not directly enhance ETC’s technological capabilities or DApp ecosystem. Sustainable growth will require concerted efforts from the ETC development community.

Frequently Asked Questions
What is the difference between Ethereum and Ethereum Classic?
Ethereum (ETH) is the product of a hard fork that followed the DAO hack in 2016, while Ethereum Classic (ETC) is the original chain that continued without changes. ETH has since evolved into a larger, more adaptable platform, while ETC prioritizes immutability.
Can I still mine ETC after the Ethereum Merge?
Yes. Ethereum Classic remains a Proof-of-Work blockchain, making it a viable option for miners transitioning from Ethereum.
Is ETC a good investment?
ETC may appeal to those who support PoW or anticipate short-term gains due to the Merge. However, its long-term potential depends on improvements in security, adoption, and network activity.
How does ETC’s security compare to ETH’s?
Ethereum has a stronger security track record and a more active development community. ETC has experienced several 51% attacks, though recent upgrades aim to improve its resilience.
Will the Merge increase ETC’s value?
The Merge may drive temporary interest and price increases, but sustained value growth will require broader utility and investor confidence.
What is the maximum supply of ETC?
Ethereum Classic has a capped supply of 210.7 million ETC, with periodic reductions in block rewards to manage inflation.
Conclusion
The Ethereum Merge represents a pivotal moment for the industry—and for Ethereum Classic. While ETC may benefit from an influx of miners and short-term speculation, its future hinges on overcoming security challenges and expanding its ecosystem.
For investors and enthusiasts, ETC offers an interesting case study in blockchain principles and resilience. Yet, for now, Ethereum remains the dominant force in smart contract platforms and continues to innovate with major upgrades like the Merge.
