Ethereum Proposes Random Block System to Boost Decentralization and Tackle MEV

Ethereum’s Bold Move Toward True Decentralization: A New Randomized Block Proposal System

Ethereum, a cornerstone of decentralized technology, faces a pivotal moment as it tackles the centralization of its block proposal system. With about 80% of its blocks proposed by just two entities, Ethereum’s commitment to decentralization is at risk. However, new research offers a groundbreaking solution—a decentralized random block proposal system—that could redefine Ethereum’s future and enhance its foundational ethos.

• Ethereum proposes a decentralized random block proposal system.
• The system aims to eliminate most of the Maximum Extractable Value (MEV).
• Leadership changes at the Ethereum Foundation coincide with this research.

The Problem of Centralization

Ethereum’s current block proposal system is a concern. As Ethereum Foundation researcher Toni Wahrstätter pointed out, two builders were responsible for 88% of blocks in early October 2024, later reduced to around 80%. This concentration undermines the network’s decentralized foundation, allowing these entities to hold most of the Maximum Extractable Value (MEV). MEV, akin to front-of-the-line privileges at a popular event, is the profit that block proposers can extract by reordering, including, or excluding transactions within a block. This leads to tactics like arbitrage and front-running, which compromise the fairness of Ethereum’s transaction processing.

Can Ethereum maintain its decentralization ethos while scaling to meet global demand? The centralization issue poses a challenge to the very principles that underpin Ethereum’s mission. It’s high time Ethereum tackled its centralization problem head-on.

The Proposed Solution

To address this, Ethereum researchers propose a decentralized random block proposal system. This system would use an identical random algorithm across all Ethereum clients, such as Geth and Nethermind, to select transactions and roll-up blobs from their respective mempools (memory pools where transactions wait to be included in a block). Pseudonymous researcher Malik672 explains, “This randomization would ensure no entity could predict or control transaction ordering,” thereby directly tackling the centralization issue.

The proposed system aims to eliminate block-level MEV, democratizing Ethereum. By randomizing transaction selection, it could also shorten block times from 12 seconds to 6-8 seconds, supporting the future roll-up requirements of Ethereum’s scaling solution, Danksharding (a scaling solution aimed at improving Ethereum’s layer-2 capabilities). Imagine a scenario where a small group of miners control the majority of transactions. This is the reality Ethereum faces today, and the proposed system is a bold move to change that.

Malik672 also acknowledges potential drawbacks, such as the sacrifice of gas tips, reduced efficiency for layer-2 solutions, and potential issues with mempool synchronization due to latency. However, he believes the advantages of increased decentralization and reduced MEV outweigh these challenges.

Leadership Changes

Coinciding with this research, the Ethereum Foundation has seen significant leadership changes. Hsiao-Wei Wang, a core researcher with a deep understanding of Ethereum’s technical intricacies, and Tomasz Stanczak, previously a developer and organizational leader at Nethermind, have been appointed as co-executive directors. These changes are seen as a strategic shift to balance optimization with Ethereum’s core values.

Tim Beiko, a core developer at Ethereum, described these changes as “one of the most consequential turning points in Ethereum’s history.” He emphasized the need to balance optimization with Ethereum’s core values, stating,

While it’s clear that many things need to change for Ethereum to win, it’s easy to overcorrect and kill the magic in search of maximal optimization.

Beiko also acknowledged the challenges ahead, saying,

There’s a lot of work ahead of us and we shouldn’t delude ourselves into taking for granted that Ethereum will succeed at the level of its ambitions.

These leadership changes come at a time when Ethereum’s price performance has been lagging behind competitors like Solana, adding pressure to implement changes that enhance the network’s efficiency and appeal. Ethereum’s journey from an early-stage project to a robust base layer for global finance and software is fraught with challenges, but the proposed random block proposal system and new leadership signal a commitment to addressing these issues head-on.

Future Implications

The proposed changes could have a significant impact on Ethereum’s block time and scalability, potentially reducing slot time from 12 seconds to 6-8 seconds. This could improve transaction speeds and support Ethereum’s future scalability efforts through Danksharding.

From a competitive standpoint, Ethereum’s move to enhance decentralization and reduce MEV could help it regain ground against rivals like Solana, known for its speed and efficiency. However, Ethereum’s focus on decentralization and security might attract users prioritizing these aspects over pure transaction speed.

From a Bitcoin maximalist perspective, Ethereum’s efforts to address centralization are a necessary step but highlight the inherent advantages of Bitcoin’s simpler and more decentralized structure. Ethereum’s complex ecosystem might always struggle with centralization issues due to its broader scope and varied use cases.

Embracing the concept of effective accelerationism, these changes could accelerate Ethereum’s growth and impact, pushing it to the forefront of blockchain innovation and potentially driving adoption across various sectors.
