Glamsterdam Slows, Hegotá Sharpens

Ethereum's next fork is stuck on block-building plumbing, while the following fork has picked a censorship-resistance feature as its main consensus change.

Ethereum's next upgrade is still moving, but the hard parts are the kind most users never see. The Ethereum Foundation's latest core-development checkpoint says Glamsterdam remains under active implementation while client teams work through changes to block building, gas pricing, and the amount of work each block can safely carry.

The main delay is enshrined proposer-builder separation, or ePBS. Today, validators often rely on outside builders and relay software to assemble profitable blocks. That market is important, but much of the coordination sits outside Ethereum's core rules. ePBS would move more of that handoff into the protocol itself.
