Ethereum faces 80% block control by just two builders. Developer Malik672's "Decentralized Random Block Proposal" could restore true decentralization.

Ethereum has a dirty little secret nobody talks about: just two block builders - Beaverbuild and Titan - control 80% of all blocks.

That’s a level of centralization that would make even the most ardent supporter blush.

Now, a mystery developer thinks they've found a way to fix this mess.

The Proposed Solution

Someone called Malik672 dropped a proposal that's turning heads in the Ethereum community.

They're calling it "Decentralized Random Block Proposal" - a fancy way of saying "let's make this fair again."

Instead of a few builders controlling everything, Malik wants to use a random algorithm that includes all Ethereum clients rather than being biased toward those with the largest stake.

It's basically taking the power back from the few and giving it to the many using random game theory. 

How It Could Work

The proposal uses crypto-grade randomness for block building by implementing Byzantine Fault Tolerance – killing MEV extraction at the block level in the process.

Transactions would propagate faster to validators across the network as well, further boosting the attractiveness of this proposal.

Most impressive is that, if implemented, this approach could slash block times from 12 seconds down to 6-8 seconds – some much-needed time savings given that Etheruem is competing with the likes of Solana for ultra-fast settlement. 

This isn't just theoretical either – Ethereum really is dangerously centralized right now.

Back in October, the Ethereum Foundation's own researcher Toni Wahrstätter confirmed the problem – it was even worse back then, when two builders were handling a shocking 88% of all blocks.

That number has barely improved since, dropping to just around 80% – hardly the level of decentralization we all signed up for. 

This Is A Serious Problem

Centralization defeats the whole purpose of blockchain – the current system (including PBS) has handed far too much power to too few players.

Malik's approach would spread block-building across thousands of global clients.

No more kingmakers, just a fairer system that aligns with what Ethereum was supposed to be.

Malik designed this to work with Danksharding's blob requirements, which is crucial since Ethereum's future scaling depends on Danksharding.

The proposal prioritizes trustlessness over maximum optimization, and for Ethereum purists, that's music to their ears after years of compromise.

Etheruem Finally Saved? 

Devs are pushing for faster upgrades across the board, with this proposal being just one piece of Ethereum's attempt to stay competitive.

With many L1s and L2s nipping at ETH's heels, fixing centralization couldn't come at a better time.

If implemented, it could fundamentally strengthen Ethereum's weakest point just when it needs it most… until new issues inevitably arise.
