Top Block Builders widget — builders ranked by blocks produced, with transaction counts

What it shows

The addresses that assembled the blocks of the live window — ranked by blocks produced, with the transaction count each packed into them. Show all opens the full ranking.

How to read it

Modern Ethereum blocks are mostly assembled by specialized builders (Titan Builder, BuilderNet, quasarbuilder), so this list reads as a builder-market share monitor rather than a validator ranking: the validator proposes, the builder builds. Entries like Lido: Execution Layer Rewards Vault appear where the fee recipient is a staking pool's vault.

As a rough baseline, the leading builder typically lands somewhere between a third and half of the window's blocks; one name taking nearly all of them — or an unlabeled newcomer suddenly ranking — is what deserves a second look. The transaction counts alongside are a quick proxy for how full each builder packs its blocks.

For the consensus-layer side of the same question — who proposed the blocks, by validator or by payout address — see Validators.

Data & update cadence

Rolling window of 3 epochs (~19 minutes), refreshed every block (~12 s).
