Ethereum researcher proposes decentralised block building

Ethereum researcher proposes decentralised block building

An Ethereum (CRYPTO:ETH) researcher known as Malik672 has proposed a solution to address centralisation in Ethereum’s block-building process and eliminate Maximal Extractable Value (MEV).

The proposal introduces a "shared random algorithm" designed to democratise block construction.

The core idea is to use Byzantine Fault Tolerance (BFT) to remove MEV at the block level, fully democratising block proposals and potentially accelerating transaction propagation.

The current Ethereum block-building process has become increasingly centralised, with a few block builders dominating the network.

Ethereum Foundation researcher Toni Wahrstätter highlighted that two builders, Beaverbuild and Titan Builder, constructed 88.7% of all Ethereum blocks in the first two weeks of October 2024.

Although this figure has decreased to around 80%, it remains more centralised than the Ethereum community desires.

Malik672's solution involves implementing a shared random algorithm that selects block proposers cryptographically, preventing profit-driven manipulation tactics.

All Ethereum clients would use an identical random algorithm to select transactions and roll-up blobs from their local mempools.

This randomisation ensures no entity can predict or control transaction ordering.

This approach could potentially reduce Ethereum’s current 12-second slot time to 6-8 seconds while supporting Danksharding’s future roll-up requirements.

The proposed system mandates that every Ethereum client generates blocks using a Verifiable Delay Function (VDF) and RANDAO for randomness, ensuring uniform transaction selection.

Validators then prune invalid transactions and reach consensus via a BFT model requiring a 3T+1 threshold.

"This system flips that: block-building spreads to thousands of clients globally, fully democratising the process," Malik672 wrote.

According to Malik672, this solution aligns with Ethereum's trustless roots and remains compatible with Danksharding's blob requirements, which aim to scale Ethereum layer 2s.

Core developer Tim Beiko characterised recent leadership changes at the Ethereum Foundation as "one of the most consequential turning points in Ethereum’s history."

At the time of reporting, the Ethereum (ETH) price was $2,447.78.
