Ethereum's Glamsterdam Upgrade Aims to Remove Block-Building Middlemen

Ethereum's Glamsterdam upgrade, scheduled for the Sepolia testnet on October 6, introduces EIP-7732, which enshrines proposer-builder separation, moving block-building away from trusted relays into protocol rules. The upgrade is part of a broader effort to reduce reliance on middlemen and increase network efficiency.

Why it matters. Developers and node operators are adapting to new validator duties, while the upgrade's success will impact Ethereum's infrastructure and trust model.
