An Ethereum researcher, known by the pseudonym Malik672, has introduced a groundbreaking proposal aimed at addressing the centralization issues within the Ethereum network. This innovative solution seeks to democratize the block-building process and eliminate Maximal Extractable Value (MEV) at the block level, potentially transforming the way transactions are processed on the blockchain.
Key Takeaways
-
Proposal Overview: The "Decentralized Random Block Proposal" aims to implement a shared random algorithm to democratize block proposing.
-
Byzantine Fault Tolerance: The proposal leverages Byzantine Fault Tolerance (BFT) to mitigate MEV and enhance transaction propagation.
-
Current Centralization Concerns: Recent data shows that a small number of builders dominate block creation, raising concerns about centralization.
-
Trustless Roots: The proposal aligns with Ethereum's foundational principles of decentralization and trustlessness.
-
Potential Benefits: The new system could reduce block creation times and improve overall network efficiency.
The Centralization Challenge
Ethereum has faced increasing scrutiny over the centralization of its block-building process. Recent statistics revealed that two block builders, Beaverbuild and Titan Builder, were responsible for constructing approximately 88% of all Ethereum blocks in early October. Although this figure has since decreased to around 80%, it remains a significant concern for the Ethereum community, which values decentralization.
Malik672's proposal aims to address these issues by spreading block-building responsibilities across thousands of clients globally. This approach would prevent any single entity from dominating the process, contrasting sharply with the current Proposer-Builder Separation (PBS) model.

The Proposed Solution
The core of Malik672's proposal is the implementation of a shared random algorithm that utilizes Byzantine Fault Tolerance (BFT). This method is designed to eliminate MEV at the block level, which has been a source of profit-driven manipulation strategies such as front-running and arbitrage. By democratizing the block proposal process, the proposal aims to restore Ethereum's decentralized ethos.
Key features of the proposal include:
-
Cryptographically Random Block Construction: All Ethereum clients would participate in block creation, reducing reliance on a few dominant builders.
-
Enhanced Transaction Propagation: The new system is expected to accelerate the propagation of transactions across the network.
-
Alignment with Ethereum's Vision: The proposal is designed to be compatible with Danksharding, a solution aimed at scaling Ethereum's layer-2 solutions.
-
Reduced Slot Times: Malik672 anticipates that the new system could decrease block times from the current 12 seconds to approximately 6-8 seconds.
Addressing Potential Drawbacks
While the proposal presents numerous advantages, Malik672 acknowledges some potential drawbacks, including:
-
Gas-Tip Sacrifice: The new system may require adjustments to gas fees.
-
L2 Efficiency Reduction: There could be a temporary decrease in layer-2 efficiency during the transition.
-
Mempool Variance: Latency issues may lead to discrepancies in the initial blocks proposed by clients.
Despite these challenges, Malik672 believes that the benefits of the proposal outweigh the drawbacks, and solutions can be developed to address the identified issues.
Conclusion
As Ethereum developers and researchers move towards a faster deployment of upgrades, Malik672's proposal represents a significant step towards enhancing the network's decentralization and efficiency. By addressing the centralization of block building and eliminating MEV, this innovative approach could pave the way for a more equitable and robust Ethereum ecosystem.
