Vitalik Acknowledges Centralization of Ethereum (ETH) Under Proof-of-Work (PoW) Consensus

Let’s talk about why PoS is a hot topic in the Ethereum community.

Known as the second-largest cryptocurrency by market cap, Ethereum started out using the PoW consensus. However, in September 2022, the Ethereum blockchain made the switch to PoS. This move has sparked some debate among crypto enthusiasts who argue that Ethereum was better off with PoW for its decentralization.

Amanda Cassatt, CEO of Serotonin, has voiced concerns about centralization risks and power balance issues since the switch to PoS. She believes that PoS has led to more centralized validation and removed important ecosystem checks and balances.

On April 26, 2024, Vitalik Buterin responded to the community’s discussions on PoS vs PoW, pointing out that PoW also had its centralization issues. He explained that the temporary nature of PoW was understood by many, which is why these concerns were not as prominent at the time.

Remember how PoW had its own centralization problems too? It’s all part of the journey towards PoS!

Some critics argue that Vitalik’s support for PoS may be influenced by the fact that Ethereum now operates on PoS, while Bitcoin remains on PoW and is seen as more decentralized.

Exploring the Challenges of Ethereum PoS

Since transitioning to PoS, Ethereum has faced scrutiny for high transaction fees and energy consumption. While PoS has reduced electricity consumption, critics still question the network’s operations.

Experts speculate that Ethereum on PoS could attract attention from government regulators, potentially categorizing it as an unregistered security token. Recent months have seen the Ethereum Foundation clashing with American regulatory bodies over the classification of ETH.
