In October, two Ethereum block builders—Beaverbuild and Titan Builder—generated 88.7% of the blocks on Ethereum’s mainnet, sparking concerns about centralization within the network. The data, shared by Ethereum Foundation researcher Toni Wahrstätter, highlights a growing trend where private order flow (XOF) is sold exclusively by certain apps, reducing competition among builders.
Centralization within Ethereum is a critical issue, as it could potentially lead to biased transaction prioritization, undermining the core principle of decentralization. Despite these concerns, some analysts argue that Ethereum’s builder-proposer architecture still preserves its decentralized nature. Ryan Lee, chief analyst at Bitget Research, explains that in Ethereum’s design, proposers select the most profitable block for validation without knowing its specific contents. This separation, according to Lee, limits builders’ ability to prioritize or exclude transactions.
However, concerns about maximal extractable value (MEV) remain. If powerful validators exploit MEV incentives, they could reorder or exclude transactions, potentially threatening Ethereum’s decentralization, according to software engineer Kishan Kumar.
Although Ethereum is progressing on censorship resistance, challenges related to XOF and centralized control may persist. Yet, the network has seen a 30% rise in validator count over the past year, signaling increased institutional adoption and potentially balancing out centralization risks.
This ongoing conversation highlights the need for stronger safeguards to maintain Ethereum’s decentralized and censorship-resistant foundation.
