In the world of blockchain technology, few debates are as heated as the one surrounding decentralization. As networks grow and evolve, their foundational designs are put to the test. Ethereum Classic (ETC) and Ethereum (ETH) share a common origin, but their paths have diverged significantly—especially in how they handle decentralization. This article explores why Ethereum Classic remains decentralized at scale, while Ethereum has increasingly moved toward centralization, particularly after its transition to Proof-of-Stake (PoS).
All Blockchains Start Centralized
Every blockchain begins with a centralized phase. This is natural—innovation typically starts with a single person or small team who conceives, builds, and launches the system.
Take Bitcoin: when it launched in 2009, only two people were running nodes—Satoshi Nakamoto and Hal Finney. For at least the first two years, Nakamoto had near-total control over development and protocol changes.
Similarly, both Ethereum and Ethereum Classic were centralized at inception in 2015. They originated from the same codebase and community effort, led by a core group of developers. Centralization at launch isn’t a flaw—it’s an expected starting point.

Small Networks Appear Centralized
In their early stages, even well-designed blockchains can appear centralized due to low participation. Bitcoin had very few nodes and miners globally during its first year. Most participants used personal computers, and hash power was minimal.
The same was true for Ethereum and Ethereum Classic after their 2015 launch. With limited node operators and mining activity, these networks naturally looked centralized.
Additionally, many projects establish foundations or non-profits early on to fund development. These organizations often hire core developers and pay for infrastructure, reinforcing the perception of central control—even if the underlying design aims for decentralization.
But appearances can be misleading. What matters isn’t how a network looks when small—it’s whether its architecture supports true decentralization as it scales.
Design Determines Decentralization
Regardless of initial centralization, the key question is: Does the system’s design enable decentralization at scale?
Many economic and natural systems follow a power law distribution—like wealth concentration or market dominance—leading to centralization tendencies. In computing, operating systems and networks often become centralized over time.
However, Bitcoin introduced a breakthrough: a design that guarantees decentralization through Proof-of-Work (PoW) and Nakamoto Consensus. This innovation enables censorship resistance, permissionless access, and minimal trust in a peer-to-peer environment.
This design principle is foundational—and rare.
Proof-of-Work Is the Only Proven Decentralized Consensus
Nakamoto Consensus via Proof-of-Work is currently the only mechanism proven to achieve true decentralization in practice.
Blockchains like Bitcoin and Ethereum Classic use PoW, which allows every node to independently verify the longest valid chain without relying on external validators or trusted parties.
In contrast, all other consensus models—including Ethereum’s current PoS system—require some level of trust in third parties:
- Validators must be identified and staked.
- Block builders are often centralized entities.
- Fork choice rules are subjective and rely on social coordination or off-chain signals.
Without an objective way to determine the correct chain, PoS systems inherently depend on trusted intermediaries—making them more akin to cloud services than decentralized networks.
Why Proof-of-Stake Leans Toward Centralization
Proof-of-Stake introduces several centralizing forces:
- No objective fork choice: Unlike PoW’s “longest chain rule,” PoS relies on complex voting mechanisms that require coordination.
- Staking is frictionless: Large stakeholders gain disproportionate influence, creating economies of scale.
- Concentration of power: A small number of staking pools and institutional validators control most of the network.
For example, over 70% of Ethereum transactions are now subject to potential censorship due to reliance on centralized relays and validator operators.
Moreover, stakers are inside the network—they cannot be easily excluded. In PoW, miners are external participants; if they misbehave, nodes can fork the chain and change the mining algorithm. This check-and-balance doesn’t exist in PoS.
Mining at Scale Promotes Decentralization
Critics argue that PoW mining also leads to centralization through large mining pools. But real-world evidence contradicts this claim.
Bitcoin has operated for nearly 15 years under PoW without becoming centralized. Its mining ecosystem is globally distributed across countries with diverse energy sources—from hydroelectric in Scandinavia to natural gas in North America and renewables in China.
This geographic and energy diversity prevents any single entity from gaining majority control. Even if one miner attempts censorship or manipulation, nodes can reject invalid blocks—and the community can hard fork if necessary.
PoW creates a resilient feedback loop: miners secure the network, but nodes have ultimate authority over consensus rules.

Ethereum Classic Is Decentralized by Design—and at Scale
Some claim Ethereum Classic is centralized because:
- It has a supporting organization (the ETC Cooperative).
- It employs core developers funded by donations.
- It has fewer nodes and lower hash rate than Bitcoin.
But these are surface-level observations.
The ETC Cooperative is not a controlling body—it’s a funding vehicle for open-source development, similar to other nonprofit foundations in decentralized ecosystems. Developers do not dictate protocol rules; upgrades require community consensus.
Node count and hash rate grow organically with adoption. What matters is that ETC uses PoW Nakamoto Consensus, the same battle-tested model as Bitcoin. As demand increases, so will security and distribution.
When investors and developers recognize ETC as the largest truly decentralized smart contract platform, its value will rise—and with it, network effects and decentralization.
Frequently Asked Questions (FAQ)
Q: Is Ethereum Classic just a copy of Ethereum?
A: No. While ETC shares Ethereum’s original codebase, it follows a different philosophy—immutability and decentralization over governance flexibility. After the 2016 DAO fork, ETC continued the original chain, rejecting intervention.
Q: Why did Ethereum switch to Proof-of-Stake?
A: Ethereum moved to PoS primarily to improve scalability and reduce energy consumption. However, this came at the cost of increased centralization risks and reduced user sovereignty.
Q: Can Ethereum Classic handle modern dApps?
A: Yes. ETC supports smart contracts and decentralized applications. While less marketed than ETH, it offers a stable, secure foundation for developers prioritizing censorship resistance.
Q: Isn’t low hash rate a security risk?
A: Hash rate correlates with security, but PoW’s design ensures that even smaller networks remain trust-minimized. As ETC gains adoption, hash rate will naturally increase.
Q: Does having a foundation make ETC centralized?
A: Not necessarily. Foundations support development but don’t control protocols. True control lies with node operators who validate consensus rules independently.
Q: Will ETC ever switch to Proof-of-Stake?
A: No. The ETC community is committed to maintaining Proof-of-Work as a core principle of decentralization and immutability.

Final Thoughts
Decentralization isn’t about appearances—it’s about architecture. Ethereum Classic may start from a smaller base than Ethereum, but its adherence to Nakamoto Consensus, immutability, and open participation makes it uniquely positioned as a truly decentralized smart contract platform.
While Ethereum relies on trusted validators and opaque coordination mechanisms post-PoS, Ethereum Classic continues the original vision: a censorship-resistant, trustless, and permissionless network secured by Proof-of-Work.
As users increasingly demand transparency and autonomy in digital systems, ETC stands out—not as a relic, but as a resilient alternative built for long-term sustainability.
