Ben Edgington, a former Ethereum client developer and current finality researcher at the Ethereum Foundation, published the first edition of a new blog series outlining a practical path to reducing Ethereum's time to finality from roughly 1,000 seconds to under 10 seconds. The core strategy is decoupling, which could alone deliver a meaningful initial speedup.

Currently, finality votes and fork-choice votes are bundled into a single attestation structure, which ties the finality process to the rhythm of individual slots. Separating the two would allow finality to operate on its own timescale, consuming otherwise-idle network bandwidth and removing the slot-length constraint.

Further incremental improvements will be designed to be deployable independently. Edgington notes that we must achieve fast finality without excluding home stakers or reducing validator set diversity. The Ethereum Strawmap places decoupled consensus as a headliner candidate for the I* fork, currently anticipated in late 2027.
