The post Vitalik Buterin Proposes Potential Design Changes to Mitigate Centralization Risks in Ethereum appeared on BitcoinEthereumNews.com.

Ethereum co-founder Vitalik Buterin addresses the rising concerns regarding the centralization risks associated with proof-of-stake systems. He emphasizes that the dominance of large stakers could lead to significant vulnerabilities, including transaction censorship and 51% attacks. Buterin highlights that the current architecture of Ethereum allows a small number of builders to control a vast majority of block production, exacerbating these issues. Vitalik Buterin warns that Ethereum’s proof-of-stake centralization could threaten the network’s integrity, suggesting innovative solutions to distribute block production and uphold decentralization. Understanding the Risks of Proof-of-Stake Centralization Vitalik Buterin has raised alarm regarding the inherent risks posed by centralization within Ethereum’s proof-of-stake (PoS) framework. As large stakers begin to dominate the network, smaller stakers often find themselves compelled to consolidate into larger pools. This growing centralization raises alarm bells due to the increased potential for critical issues such as transaction censorship and 51% attacks, which could compromise the network’s security and integrity. The Core Problems of Block Construction At the heart of the current challenges is Ethereum’s approach to block construction known as proposer-builder separation (PBS). This system segments the responsibilities between validators who propose blocks and builders tasked with organizing transactions. While this separation promotes decentralization among validators, it inadvertently introduces a risk where those engaged in specialized tasks tend to cluster, resulting in significant centralization. Buterin pointed out that just two builders were responsible for creating an overwhelming 88% of Ethereum blocks as of October 2024. This concentration implies that if these entities chose to censor transactions, it could lead to alarming delays—extending processing times from six seconds to an average of 114 seconds. Proposed Solutions to Mitigate Centralization To counteract these centralization tendencies, Buterin proposed several innovative strategies aimed at redistributing the responsibilities of block construction. One viable solution rests on returning transaction selection tasks to…
